Composition is the leading cause of haze weather vocs many of organic waste gas emissions, this article first to vocs, summarized the origin of organic waste gases and damage combined with his environmental waste management experience for many years and are commonly used in waste management skills made a brief analysis and discussion, and then on the source of organic waste gas to take the most useful measures for the prevention and control of down the effects of pollutants on the human body and natural environment. The primary provenance VOCs emissions, it first refers to a kind of evaporation of organic matter, which is under normal temperature conditions, the vapor pressure of the full scale beyond 133.32 Pa, it under the condition of normal pressure fee of 50-260 ℃ range of organic compounds in atmospheric pressure and room temperature conditions, the next is mountable evaporation of an organic liquid and solid. VOCs exhaust emission sources are relatively many, and extremely complex, with human-oriented and natural origin as the main source. The origin of humanity mainly includes mobile source, day source and industrial source. The natural history mainly includes anaerobic process of wetland, forest fire, wildlife discharge, vegetation discharge, etc. VOCs waste gas is a kind of waste gas with relatively extensive distribution scale. To a certain extent, human activities are the source of VOCs emissions center. In daily practice, burning straw, building decoration, kitchen fume and so on will constitute and release the necessary quantitative VOCs waste gas. During the practical operation of engines of ships, planes and cars, it will also discharge mandatory VOCs waste gas. During the operation of industrialized production, chemical fiber, petroleum exercise and other relevant professional practices will also constitute a lot of VOCs waste gas, damaging part of the environment. Fundamental damage analysis Next to VOCs waste gas, there are a lot of evaporative organic compounds, including ammonia, ketones, hydrocarbons, aldehydes, acids, etc., which are extremely harmful to people's livelihood and production environment and health. During the period of industrial production, a lot of VOCs waste gas is usually released, which is of great harm, mainly reflected in the following aspects: if there is relatively high concentration of benzene vapor in the side of VOCs waste gas, it may directly cause the human body to present a deadly and acute toxic condition; In VOCs waste gas next to the compounds containing aromatic amine, organic nitrogen, polycyclic aromatic hydrocarbon organics, and so on, and these compounds have a high carcinogenic rate; This kind of benzoic acid organic matter in the side of VOCs waste gas, once enter human body, can cause human body to present the cell directly next to protein deformation or coagulation, constitute human body to present each kind of bad symptom to reflect; Once it enters the human body, it will directly enter the respiratory system and nervous system of the human body. As a result, the human body will present symptoms such as breathing difficulties, neurological disorders, asphyxia, and even endanger people's lives. So, besides can constitute irreversible damage to the human body, after gradually VOCs waste gas emissions to the atmosphere, also can destroy the atmosphere of a temporary ozone, the greenhouse effect is more serious, will ultimately lead to changes in global climate presents adverse condition, which leads people to a living walls and produce of atmospheric environment day setting, ecological balance problem is more serious. Discussion of traditional processing skills 1. Adsorption processing skills In today's VOCs waste gas traditional processing skills, adsorption processing skills have been the most commonly used treatment skills. The basic principle of adsorption and treatment skill is to rationally use solid adsorbent, such as carbon fiber, molecular sieve, activated carbon, etc., for the constituted VOCs waste gas, to carry out useful treatment, adsorb and purify the VOCs waste gas and discharge it into the atmosphere. To a certain extent, this kind of traditional adsorption processing skill has the greatest advantage in its low cost of practice, extensive practice and high net rate. So, for some organic waste gas with low air ratio, low concentration and temperature, this kind of adsorption treatment skill is more effective. 2. Incineration treatment skills Among the traditional VOCs waste gas treatment skills, incineration treatment is also widely used. This incineration skill is, above all, the direct use of incineration, which turns VOCs waste gases and nearby pollutants into water (H2O) and carbon dioxide (CO2). This incineration treatment skill can be divided into catalytic incineration, thermal incineration and direct incineration. Catalytic incineration, which mainly USES the catalytic auxiliary function, ends the oxidation during the abundant incineration of some organic gases, and releases the corresponding heat from those gases which are harmless in the process of homogenization. This incineration treatment skill has now entered the sophisticated stage of skills, which can finish the treatment of VOCs waste gas without heat. Thermodynamic incineration, which mainly USES some auxiliary fuel such as the addition of natural gas, to treat some organic waste gas of low concentration. Direct incineration is the first direct incineration of VOCs waste gas under high temperature conditions. This incineration treatment is suitable for high concentration of organic waste gas and high calorific value gas treatment. New processing techniques Biological processing skills Biological treatment skills, which primarily use microorganisms to degrade the VOCs waste gas and organic pollutants next to it, thus creating a less harmful and perhaps harmless substance. VOCs is surrounded by many compounds that can damage the environment and human body, but they are also a source of carbon and power that can provide fundamental life resources for some microorganisms. Through the use of some cultivated and domesticated microorganisms, some of the pollutants can be useful into inorganic substances to achieve the best exhaust gas purification. After biological treatment skills to deal with VOCs waste gas, the use effect is relatively ideal, and there is no secondary pollution present. Therefore, the biological treatment skills in China have reached the stage of maturity. 2. Ability to handle photocatalytic oxidation Photocatalytic oxidation treatment is a relatively new treatment of VOCs waste gas. This kind of treatment skill, the first under the action of light compose must chemical reaction, the harmful material near the waste gas is useful change into the harmless compound, the pollution of VOCs waste gas decreases. At present, the technology of photocatalytic oxidation treatment in China is still under further research. It is reported that through the photocatalytic oxidation treatment skills to VOCs waste gas treatment, VOCs waste gas next to the pollutant practical removal rate of around 80%, the use of more ideal. 3. Low temperature plasma processing skills Low temperature plasma processing skills, its fundamental use principle for using the rf discharge and corona discharge skills such as the method, under the condition of normal pressure and room temperature to obtain a lot of active particles with high energy electrons, in many active particles with high energy electron interaction, the VOCs emissions down the poison useful compounds are converted into less harmful or harmless (H2O) and carbon dioxide (CO2), nitrogen (N2), etc. Low temperature plasma treatment skill is a new kind of VOCs waste gas useful treatment skill proposed and used in recent years in China. Now, in the treatment of VOCs waste gas, low-temperature plasma treatment has become the most advanced waste gas treatment skills, the use of more ideal.

The dust layer on the outside of the filter cylinder of activated carbon adsorption equipment xEq4o0O is shaken to the ash hopper due to deformation of the filter barrel, and the dust is discharged by the ash hopper through the discharge valve. The resistance of the filter cylinder deduster of activated carbon adsorption equipment increases with the increase of the dust layer thickness on the filter surface. Clear the dust when the resistance reaches a certain value. Of PLC program control pulse valve opening and closing, a first chamber lift valve closed, will be truncated filtering flow, and then the electromagnetic pulse valve open, compressed air and a short time the case on the rapid expansion, the influx of cartridge, cartridge expansion deformation produces vibration, and under the action of reverse flow scouring, attached to the filter bag dust on the surface of the appearance, stripped fell into the hopper. In the process of catalytic purification of waste gas, the waste gas is fed into the heat exchanger by the fan through the pipeline and heated to the starting temperature required for catalytic combustion. The waste gas is preheated and burned through the catalyst layer. Due to the effect of catalyst, catalytic combustion exhaust gas initial burning temperature of about 250-300 ℃, much lower than direct combustion method of combustion temperature 650-800 ℃, thus is far less than direct combustion method for energy consumption. At the same time, under the action of catalyst, the reactive gas generates a certain amount of heat, and the high-temperature gas enters the heat exchanger again and is cooled by heat exchange, and finally is discharged into the atmosphere by the fan at a lower temperature. Activated carbon adsorption equipment Working principle: The air flow containing dust enters the air box through the lower tuyere, and evenly distributes the air flow to the filter element through the guide baffle. Under the action of the filter element, dust is absorbed on the surface of the filter element, and clean gas is discharged through the outlet pipe. As the filter parts are installed vertically, good cleaning effect can be guaranteed. The cleaning of filter material of the purifier is realized through the spray device controlled by the pulse control instrument: when the purifier runs for a period of time, fine dust is absorbed on the surface of the filter material, which reduces the permeability of the filter material. Signals are sent out by the pulse control instrument at regular intervals to control the electromagnetic valve, and clean compressed air is ejected by the valve port. The dust adsorbed on the surface of the filter material is removed under the action of air flow and falls in the dust collector in the lower part of the chamber body. Pulse spray requires 0.4 ~ 0.6mpa of clean compressed air and must maintain continuous and constant air supply during operation. Integrated filter cartridge deduster is the integral design of fan, motor and filter unit. The heat of activated carbon adsorption equipment is reused through heat exchanger. 2. Zhonghan environment control system mainly consists of PLC electric control cabinet, temperature display instrument, electric valve actuator and panel simulation flow chart, etc. Its function is to control the switch of related valves in the pipeline during work. Control the start and stop of electric heaters, control and indicate the heating temperature, reaction temperature, air inlet temperature and air outlet temperature of the catalytic bed according to the requirements of process conditions. Application field multi-filter cartridge deduster is widely used in mechanical, casting, metallurgy, building materials, chemical industry, automobile, ship, equipment manufacturing industries in the electric arc welding, CO2 protection welding, MAG protection welding, special welding, gas melting cutting on carbon steel, stainless steel, aluminum and other metals when welding the purifying treatment of smoke. Activated carbon adsorption equipment Is the filtering unit for the mid - h environment The air inlet of the precipitator is equipped with a ash deflector, which can equalize the air and protect the filter core from damage of large particles. The filter unit adopts the vertical end cover type rapid installation method, which is more convenient for the disassembly and maintenance of the filter core. The vertical installation of the filter core makes its ash cleaning more thorough and clean. The filter core is made of imported polyester coated filter material with good air permeability and the filtration accuracy is up to 99.9%, meeting the discharge requirements. Blower unit Fan built - in design, compact structure; Fan impeller: compression molding of blade and wheel cover mold, precision, with a balance level of no more than 4.0 (national standard), with good air power, high efficiency, low noise and stable performance. Represents the environment control system The control system type design can be based on the requirements of the field operating environment of the equipment, and the installation position is more flexible, which can reduce the pollution of internal dust to electrical components and extend the service life. The variable frequency control can be selected for multi-station centralized processing. Through the automatic frequency converter, the system can adjust the rotation speed of the fan according to the actual air volume demand, reduce the operation energy consumption, reduce the wear on the filter core and extend the service life of the filter core. The high-energy ozone in the form of meteor shower in activated carbon adsorption equipment has non-collision with the molecules (principle) in the medium, transforms the energy into the internal energy of ground state molecules (atoms), and generates a series of processes such as excitation, dissociation and ionization, which make the contaminated media in the activated state. Achieve purify deodorant effect. Photooxygen catalytic waste gas purification equipment produces active free radicals under the action of ionizing the pollutant medium, and the activated pollutant molecules are removed after the directional chain chemical reaction. When the average energy exceeds the chemical bond binding energy in the contaminated medium, the molecular chain breaks down, the contaminated medium decomposes, and is collected under the action of the ozone generator adsorption field. The rotary adsorption bed is used to adsorb and concentrate the organic waste gas. The concentrated organic waste gas is removed from the desorption regeneration area and introduced into the catalytic combustion purification device by the regenerative fan for further purification treatment. The whole device is divided into two modules: VOC concentration zone and VOC purification treatment zone. live Range of application It is applicable to centralized control of welding dust, plasma and laser cutting dust, centralized control of polishing and polishing dust, and centralized control of new material processing dust. We can design excellent smoke and dust capture device and pipe system according to different field working conditions of customers, and select the corresponding type of deduster required air volume.

With the rapid development of the furniture industry in recent years, more and more furniture is processed on wood-based panels, resulting in a large amount of particulate matter emissions from drying after the application of glue on wood-based panels, thus causing pollution to the environment. The waste gas treatment equipment provides a filter tool for the waste gas produced by the factory in the process of production. The waste gas produced by the state should be treated by the equipment before being discharged. Waste water is produced during the production of fibreboard, particleboard and plywood. In addition, there is the rubber factory flushing equipment waste water, from the heat center boiler waste water and domestic sewage. The waste gas pollution in the production of plywood mainly comes from the waste gas discharged by the veneer dryer, as well as the harmful gas such as formaldehyde generated in the process of gluing and hot pressing, as well as the dust emitted by the sanding process. In the production of particleboard, free formaldehyde is produced in the process of sizing, hot pressing of slab, cooling of wool board and sawing of edge. Dust can be produced in the process of making, drying and sanding of wood. In addition, a large amount of drying exhaust gas is produced in the drying process of shaving, which also contains a certain amount of VOC and particulate matter. At present, the waste gas treatment equipment mainly adopts dry production technology, and a large amount of exhaust gas is discharged in the fiber drying section. VOC, particulate and other pollutants are the main pollutants. In the process of hot pressing and cooling, it emits free formaldehyde and other gases. In wood chip cutting, screening, molding and other sections, there will be a certain degree of dust pollution. With the continuous improvement of emission standards, enterprises need to adopt different combined treatment methods to control waste water and waste gas pollution in production, so as to promote the long-term development of enterprises. Geyuan provides you with DMF waste gas treatment, waste gas treatment of food factory and paint waste gas treatment and other waste gas treatment services. It also specializes in the production and sale of waste gas treatment equipment, VOC online monitoring equipment, RCO catalytic combustion equipment and zeolite rotary equipment and other environmental protection equipment.

Waste gas treatment equipment engineering environmental protection equipment 1. When the dry paint fog filter is working, the paint fog is flying, the paint fog particles are small and the viscosity is large, which is easy to adhere to the surface of the material. The paint mist part is carried away by air flow and filled with our special filter material through the paint fog filter, which can not only remove 95% of the paint dust, but also guarantee the minimum air pressure loss. To ensure the efficiency of activated carbon in the next process and extend the service cycle, thus reducing the cost. 2. Activated carbon adsorption tower, which is suitable for large flow and low concentration of organic waste gas, adopts TF efficient honeycomb activated carbon with specific surface area (adsorption area) up to 500-1500m2/g. It has high surface activity and adsorption capacity due to its large surface area. The low concentration of organic gas discharged is adsorbed on its active surface to achieve the purpose of waste gas purification. Description of waste gas treatment equipment treatment process The waste gas of paint spraying is generated in the process of paint spraying. Under the action of air pressure, liquid paint forms the particulate matter of atomized dust and volatile triphenyl and other organic hazardous substances with high concentration and small particle size. Most of them are below 10 plus m. Spray paint waste gas after dry mist filter purification treatment, waste gas in the tiny dust, not solidified paint particles and a small amount of organic waste gases to be absorbed by the filter, exhaust gas to ensure that most of the dust particles in a blocked, again into the activated carbon adsorption device, organic gas in the bed by activated carbon adsorption, purge gas by pressure fan through a vent air emissions. The waste gas treatment efficiency of the paint exhaust treatment project is over 95%, which greatly improves the atmospheric environment. After regenerating, the saturated activated carbon of the waste gas treatment equipment can be recycled: the steam generated by the activated carbon regeneration device will blow out the substances adsorbed by the activated carbon, and then enter the catalytic bed for combustion, so that the organic gas will eventually be converted into harmless gases such as H2O and CO2.

Sewage and waste gas are two major source of environmental pollution, due to the wastewater contains various chemicals or toxic ingredients, so very easy to react with each other and produce the stench gas, sewage factory waste gas processing factory emphasize in this case must take measures to governance, therefore in sewage and waste gas governance also cannot be ignored. To be specific, the main points about the treatment of odorous waste gas include the following aspects. Sewage plant waste gas treatment of the malodorous waste gas treatment of the key points One, want to produce odour material and appraisal If we want to deal with odorous waste gas, we should look for the root cause, so that we can complete such treatment more thoroughly. Therefore, waste gas treatment experts of sewage treatment plants emphasize the importance of identifying substances related to the specific source of the stench. Through the unremitting research of experts, it is found that the odorant material mainly consists of carbon, nitrogen and sulfur elements. At the same time, the waste gas treatment experts of sewage plants also found that there were active groups in these odorous gases, and it was very easy to have chemical reactions, easy to be oxidized by oxygen, and also after such reactions, the odor would disappear, so it could be well used to treat the odorous gases. Try to measure the odor so that it can be better identified Cheap and environmentally friendly waste gas treatment experts stress that it is not easy to identify the source of the odour because the waste gas itself is so complex. Waste gas treatment experts of sewage plant also introduce when measuring, what can be used commonly is olfactory method, it is the gas that diffuser collects to put special instrument and air mix specifically, let by the 4 people that have received special training to distinguish odour respectively, achieve these two purposes thereby.  Three, to take the appropriate method of deodorant  Methods that can achieve anti-wrinkle effect are generally common, such as adsorption and combustion methods using activated carbon as the medium, etc. Besides, the experience of waste gas treatment experts in sewage plants shows that the use of these methods is relatively effective, and the most economical method is biological absorption method. Waste gas treatment experts of sewage treatment plants introduce that biological absorption method can be used to remove odorous substances as long as waste gas is prepared with water solubility. These are some of the aspects that are included in the treatment of odorous waste gas from waste water treatment plants. In addition, biological methods can be used for deodorization, because this process is very simple and USES natural resources, so the cost is relatively low. But professional waste gas treatment expert of sewage plant reminds every kind of method has limitation, because this is in real management process, should want many aspects comprehensive consideration, just can have good effect.

Summer, less haze, more blue sky and white clouds, although very hot, but still air conditioning! You can't help but feel the beauty of life in summer. A bombshell falls, the temperature rises and indoor pollution comes! Especially summer, the temperature is high, pressure is low, humidity is big, make indoor air convection is reduced accordingly, also cause the retention of pollution gas, indoor air pollution also entered accordingly high issue period. Summer is the season with high incidence of toxic and harmful gas pollution such as formaldehyde and benzene. As the temperature rises, the molecular thermal motion intensifies, which leads to the accelerated evaporation of indoor air such as formaldehyde and the increased release quantity. Indoor uncomfortable all over, bosom is frowsty, cough, sneeze to wait to be the disaster that indoor air pollution causes. Summer is the season with the most germs and the fastest breeding. Not only do these bacteria that lurk around us become allergens, causing allergic symptoms in some people, but more importantly, they can easily get sick in the summer. Some people with poor resistance are prone to abdominal pain, diarrhea, skin irritation and other symptoms in summer. At the time of year, indoor air pollution is four to five times higher than outdoor air pollution. So home air purifier must not be idle, indoor air purification, summer is still very important!

1. From the perspective of working principle The function of the fresh air system is to purify the outdoor air and then introduce it into the indoor air. Meanwhile, the indoor dirty air is discharged into the outdoor air and the indoor air is constantly replaced. And air purifier is depending on the fan will indoor air suction machine again after filtration purification released into the indoor, and the air or the original air, only will be of some pollutants in the air. 2. From the perspective of the filtration system The filtration system can be divided into three types from the perspective of filtration, namely, filter screen (filtering large particles), adsorption (the adsorption capacity is determined by the mass and volume), and decomposition (some chemical action). From filtering methods are divided into mesh (early effect, the main filter large particles, improve the working efficiency of the filter system) behind, electrostatic dust collection (high voltage electrostatic stick to small particulate matter), hepa/activated carbon (adsorption), light catalyst (nanoscale titanium dioxide photocatalytic effect under the action of a light source, can effectively decompose the small particles, organic gases, viruses, bacteria, etc.), the general air purifier is three to five layers of filtration, filter and activated carbon on the second floor, combined with the electrostatic dust collection, and hao court has six layer filtration system, air system includes electrostatic dust collection, hepa filter, photocatalytic system, Moreover, due to the small volume of air purifier, its adsorption capacity is limited, and more frequent replacement of filter element is often required. 3. From the perspective of using effect 1. The effective purification area of a fresh air system can reach 200 square meters, while the purification area of air purifiers is usually no more than 20 square meters. 2. Air purifiers cannot solve the problem of excessive carbon dioxide when sleeping at night, and fresh air system can solve this problem. 3. Air purifier cannot solve the problem of bacteria and viruses caused by air conditioning, and the new air system can solve this problem. Therefore, the fresh air system and air purifier are very different, and the new air system is better than the air purifier in function attribute.

The function of the purifier are: air purification air, air negative ions to make dust, smoke, pollen, water droplets and gas suspended microbes such as soluble substances easy coagulation, can with the organic matter in the air oxidation and eliminate the peculiar smell, thus has the role of clean air, improve environmental quality; 1. Sterilization: air negative ions can be combined with bacteria and microbial viruses attached to dust in the air to reduce it. Experimental studies have shown that air negative ions have a strong inhibitory effect on air microorganisms, making viruses lose their ability to attack cells, and thus have the effect of killing and reducing bacteria and purifying air. 2. Eliminate static electricity: static electricity is generally caused by ions with positive electric charge. Negative ions in the air will combine with positive ions to eliminate static electricity. 3. Biological effect: experimental research and clinical observation show that air negative ions have many biological effects on the body. Recommend a xindu air purifier, it has this function, after use, the air becomes very fresh, can reduce various kinds of air pollution, bring you comfortable environment Other purification methods: 1. Washing method. Use of siphon and centrifugal principle, will be mixed in water purifying agent by siphon principle to inhale the lower part of the motor base coaxial centrifugal turbines in the straw, through exchange cover pole machine high speed rotating, reuse centrifugal principle, will be mixed in water purifying agent spray form a layer of water film within the inside, will absorb dust and bacteria in the air to the water. Negative ion method. Hydroxyl ion after contact with the harmful gas of floating in the air can restore from atmospheric pollutants, nitrogen oxides, cigarettes and other produce reactive oxygen species (oxygen free radicals, reducing excessive reactive oxygen species to the harm of human body. Functions of air purifier: 1. Air purifier, as the name implies, is the function of purifying air. 2. Filter out impurities in the air that are harmful to human health. 3, adsorption and decomposition or transformation of various air pollutants (generally include PM2.5, dust, pollen, peculiar smell, formaldehyde, decoration pollution, such as bacteria, allergens, etc.), and effectively improve the cleanliness of the air.

There are two types of waste gas purification tower, respectively vortex plate spray tower (dust removal desulfurization), packing spray tower (and), and two kinds of tower is suitable for many industries, but also need to take regular check on them. What should the exhaust gas purification tower pay attention to when maintaining? 1. Check the dosage of neutralization potion every day, carefully record and make dosage calculation to supplement in time; 2. Check the running condition of the water pump every day, and check that the sprinkler spray is normal; 3.

Clean the liquid tank of the medicine cabinet every month or regularly to reduce the obstruction of the hot water pump.

The main sources of waste gas treatment are industrial noise, traffic noise, construction noise and social life noise. Soil pollution is caused by human activities to enter the soil and accumulate to a certain extent, causing the deterioration of soil quality. It is mainly due to industrial, domestic wastewater and solid waste, pesticides and fertilizers, as well as atmospheric fallout. Pesticide pollution, environmental protection equipment, pesticide and its degradation products to soil, water and air pollution. It mainly refers to organic chlorine, organic phosphorus and organic nitrogen pesticide pollution. Severe acute or chronic poisoning can cause people and animals and plants. It is the pesticide and its degradation products in the natural environment, which pollutes the atmosphere, water and soil, destroys the ecosystem, environmental protection equipment and facilities, and causes acute or chronic poisoning of people and animals and plants. Pesticides are also classified as organic and inorganic. Pollution is mainly caused by organochlorine pesticides, organophosphorus pesticides and organic nitrogen pesticides. There are many reasons for pesticide contamination, such as the long-term use of some banned high toxic pesticides, or the indiscriminate use of crops. Chemical fertilizer pollution, environmental protection equipment and facilities, excessive use of chemical fertilizer and cause water, soil and air pollution. Nitrogen compounds that have not been used in time by plants can be contaminated by the presence of no3-n, which cannot be adsorbed by the soil colloid, and the soil water will be transferred to the root density layer below. It can lead to eutrophication of rivers, lakes and inland seas; Soil is polluted and physical property deteriorates; Increased levels of toxic substances in food, feed and drinking water. In order to prevent pollution, the use of chemical fertilizers should be controlled and managed.

The main equipment in chemical washing tower is made of high quality PP material, has the characteristics of anti-corrosion: design before chemical washing tower body and level of venturi structure, can effectively remove dust and absorb part of the water-soluble gas composition; The nozzle is easy to install and the clogging rate is low. The other special structure can effectively remove fog, reduce water consumption and save dosage. Chemical scrubbing towers use the contact between the gas and the liquid to transfer the pollutants in the gas to the liquid, then separate the clean gas from the contaminated liquid to purify the air. The exhaust gas is processed through the filling type scrubber, which is treated by air - liquid reverse absorption, that is, the liquid is poured down from the top of the tower with a spray of mist (or small droplets). The exhaust gas is from the tower body (reverse flow) to the gas liquid to connect the chemical washing tower. This treatment can cool the exhaust gas, remove particles and purify the gas, and then after the removal of fog, it is discharged into the atmosphere. Chemical scrubbing tower is a new kind of purification equipment which purify high concentration of chemical waste gas. It has the characteristics of fast reaction rate, high purification efficiency, compact structure, small footprint, corrosion resistance, good aging performance, light weight, easy installation, transportation, management and maintenance. Introduction to chemical scrubbing tower structure: Tower body: according to the different characteristics of the exhaust medium, there are various materials such as fiberglass, carbon steel, stainless steel, engineering plastics and so on. Packing: it is the key factors influencing the treatment effect, under the condition of different operating conditions (surface load, total ratio surface area, etc.), using different materials, in the form of filling material to meet the requirements of a good contact with gas and liquid. Spray system: according to different packing form and exhaust characteristics, different flow, pressure, diffusion range of nozzle, water pump and pipeline synthesis system are selected. Defoaming device: the main function is to intercept the water mist carried by the gas after cleaning, there are different forms to choose from. Chemical washing tower is mainly to the opposite direction of liquid or gas into the packed bed, gas distribution board, will average distribution of the gas in the spherical raschig ring, each point contact, stuffed with increased contact surface area, in order to remove the particles in the gas and liquid absorption of harmful gases. It is widely used in the treatment of acid waste gas purification and noxious gas. The washing tower is divided into vertical scrubbing tower and horizontal scrubber tower. Vertical generally is round, horizontal is generally square. The chemical scrubbing column is customized according to customer's requirement.

Fire ventilation equipment mainly refers to when there is a fire in the room, there will be a lot of smoke, it is the effect is to discharge the smoke indoors. Fire smoke exhaust fan has a smoke exhaust valve, exhaust valve at ordinary times you are closed, open automatically when the fire broke out, it is with the alarm host connected, open is the condition of fire automatic alarm system, fire alarm host in the automatic state, fire smoke exhaust valve automatically opens, linkage fire smoke exhaust fan. The higher the building is, the worse it is. What happens after a fire? Shenzhen xicheng plastic co., LTD. Thinks this is positive. Therefore, we should do well in the anti-smoking measures of the building. With the development of society, more and more complex and diverse high-rise residential buildings have been built in various parts of the country. Because of the complex functions of such buildings, there are more fire factors and more ways of spreading. Harm is big. The evacuation is difficult and it is easy to cause significant losses. Therefore, the design of high - level civil buildings is particularly serious, and the anti-smoke design is part of the manmeng part of high - level civil building fire protection design. It plays a vital role in evacuation and fire fighting. It is also the main content of fire fighting professional review, so we believe that this aspect should arouse the attention of all aspects. Therefore, we need to pay attention to the following points in the installation of smoke exhaust machine: 1, the smoke exhaust fan at the ends of the flexible soft must as a-class non-combustible material, packing material must be as a-class non-combustible material (fire according to the function is divided into: canvas anti-corrosion type, radiation type, clean air type, resistance to high pressure incombustible type four; According to the thickness: no steel wire 1.1mm, 1.3mm single surface coating with steel wire, 1.6mm steel wire and 3 kinds of glue. The specification is 1 by 50, 1.2 by 50 and 1.25 by 50. 2. The exhaust fan and duct adopt the hose (flexible material and not burning), the length should not be less than 200mm, the diameter of the pipe is the same as the inlet and inlet of the fan. In order to ensure that the hose does not distort deformation during the operation of the system, it should be installed in a moderate degree. For the canvas hose installed in the suction side of the fan, it can be installed a bit tighter to prevent the fan from being inhaled and reduce the section size of the canvas hose. 3, civil before pouring concrete, with professional design drawing review the location of the foundation, based on the surface of the top elevation, the basis of geometry size, the reserved bolt holes, location and depth of the top of the base level should not be a positive error (i.e., unfavorable and bring up the design elevation). 4. The pipe diameter of the fan outlet can only be larger and not smaller, and the final outlet should be installed with the anti-worm net, and the wind and rain cap should be added to the wind. Usually smoke of high-rise civil buildings facilities mainly includes the smoke prevention stair well and room, before the fire elevator room, share before the room, stair, closed, refuge floor (between) and other places set up smoke prevention facilities, basement, walk inside, the atrium, with no Windows or with fixed window set who smoke in areas such as the room facilities, smoke smoke hanging wall between partitions, etc. Smoke control facilities are essential to protect the safety of people's life and property of tall buildings fire safety facilities, but as part of the design, construction personnel to smoke facility structure, function and performance of the lack of understanding, to the national standard understand thoroughly, often lead to some problems in the design and construction.

Introduction to the products of shenzhen xi cheng PP (polypropylene) PP board (rod, tube) is a semi-crystalline material. Copolymer of PP materials with low heat distortion temperature (100 ℃), low transparency and gloss, low rigidity, but has a stronger impact strength. The strength of PP increases with the increase of ethylene content. Characteristics of PP board The PP board has the characteristics of light weight, uniform thickness, smooth surface, good heat resistance, high mechanical strength, excellent chemical stability and electric insulating and non-toxic characteristics. PP board is widely used in chemical containers, machinery, electronics, electronics, food packaging, medicine, decoration and water treatment PP board practical temperature can reach 100 degrees, acid and alkali resistant equipment, environmental equipment, waste water, waste gas emissions equipment, washing tower, clean room, semiconductor factory and related industrial equipment, and optimization of manufacturing plastic water tank material, including PP thick plate is widely used in drawing, punching plate, etc. How to identify the quality of PP board 1. Touch with the hand to see if the surface is smooth and smooth, and the color particles are uniformly bright. At present, the wholesale market of PP sheet metal is mainly white and transparent. Generally, the recycling is not white, so we usually think that the color white is good, in fact, this statement is also one-sided. Due to the rapid updating of the technology, the color of pp sheet is not easy to see the good and poor. But it can be touched by hand, and the coarser surface particles may be adulterated with other impurities. 2. Smell the smell, good PP plate is not smell, bad smell. 3, use the hand to pinch, PP plank material has very strong hardness, if can knead to transform easily, that is not good. 4, bad, good PP sheet material, resilience is better, it is easy to be smashed of course is not good. 5. It's good to see this method on fire. If the material is mixed with other recycled materials, it will emit black smoke and a pungent smell. Good materials will not have black smoke after burning. The liquid will also be clean.Shenzhen city Xicheng Plastic Co., Ltd. Located in Bao an District, Shenzhen, The company mainly produces waste gas treatment equipment, ventilation equipment, exhaust tower, activated carbon tower, washing tower, PP board, PP pipe, PP wind valve, PP elbow, and other ventilation accessories.

Studies have shown that the proportion of organic matter in PM2.5 is 50 to 70 percent, much of which is converted by VOCs through photochemical smog. Ozone in the pearl river delta region of China, is the main atmospheric pollutants, and is the precondition of ozone generated by organic waste gases, if you can reduce organic waste gas in the root, will be able to effectively abate photochemical smog. Most of the organic waste gases are poisonous, can smell smell, when in the high concentration organic waste gas in the air, even a short period of time contact, also can appear the symptom such as vomiting and headache, and even more severe symptoms such as seizure, fainting, at the same time can cause a person's memory decline, damage of kidney, liver and other human body function system. In particular, organic waste gases such as toluene and styrene can smell like odors even in low-concentration environments. Most of benzene is harmful to the blood system, nervous system and reproductive system, causing damage to human blood, nerve and reproductive system. Organic waste gas, if released into the atmosphere, enters people's living areas and can seriously affect People's Daily life and work, and the natural environment of our existence will be affected accordingly. As one of the most common pollutants in volatile organic waste gas, toluene is one of the main raw materials used in organic chemical industry. It is often used as solvent and additive. Toluene steam inhalation and skin absorbed into the body through respiratory tract, long live in containing toluene environment, there will be a nervous breakdown, women can appear menstrual disorders, dry skin and skin rashes. Toluene exhaust gas is discharged into the atmosphere, which not only causes serious pollution to the atmosphere and water, but also endangers the life of life on earth. There are four main hazards of volatile organic waste gas: (1) it has the stench, toxicity and carcinogenicity, which endangers the health of the human body and causes certain harm to the environment; (2) at noon or mid-afternoon, sunlight can be absorbed into the sunlight to generate photochemical smog and produce secondary organic aerosols. (3) some organic waste gases can cause the greenhouse effect; (4) part of halogenated hydrocarbon organic matter into the stratosphere, in the land of the sun's rays, in particular, the role of ultraviolet radiation, ozone and a series of chemical reactions, such as serious damage to the atmospheric ozone layer, the enhanced greenhouse effect.

The working principle of waste gas treatment equipment products: 1, through the special excitation light source produce different energy of light quantum, using the strong absorption of the photons, foul-smelling substances in a lot of can carry the bombardment of the light quantum foul-smelling substances molecular dissociation and inspire. 2, the use of free oxygen decomposition of light quantum oxygen molecules in the air, the reactive oxygen species, shenzhen industrial waste gas treatment equipment in xian cheng environmental protection is worthy of your trust, for free oxygen carrying electron-positron unbalanced so need to combine with oxygen, which produce ozone. 3, ozone under the action of the photons can produce a lot of new ecological hydrogen, oxygen and hydroxyl oxygen reactive group, part of foul-smelling substances can react with reactive group, eventually translate into harmless material such as CO2 and H2O, so as to achieve the purpose of removing odorous gases completely. Because of its excitation light source the light quantum average energy in ev 1 ~ 7 ev, proper control of reaction conditions can be implemented generally difficult to implement or make slow chemical reactions become very quickly, greatly enhance the efficiency of the effect of reactor. 4, by collecting system will fetor into light quantum purification device, in the use of special excitation light source the light quantum induced after a series of reflection, the stench harmless material is decomposed into CO2, H2O and other ingredients, the device is a kind of green environmental protection air purifying device function is stronger. Without secondary pollution, the waste gases after the reaction are mainly nitrogen, oxygen, water, carbon dioxide and other harmless gases.
