Description
Technical field
The utility model belongs to field of Environment Protection, relates to the purified treatment of organic exhaust gas, especially a kind of modularization organic waste gas purifying treatment system.
Background technology
A large amount of organic gas pollutant is produced sometimes in the industry operation process such as application, printing, petroleum and chemical industry industry, working environment and atmospheric environment are made a big impact and destroys, need to carry out administering and processing, to reduce the harm of these pollutants to atmospheric environment and field personnel's personal safety.Organic pollution in air is mainly VOC (VOC), generally refers to and holds volatile organic compound at ambient temperature, as hydro carbons, halogenated hydrocarbons, nitrogen hydrocarbon, oxygen-containing hydrocarbon, sulphur hydrocarbon, aliphatic hydrocarbon, aromatic hydrocarbon etc.Most of VOC class material has neurotoxicity, kidney and hepatotoxicity, some even has carcinogenesis, and blood circulation system and cardiovascular system can be damaged, gastrointestinal disturbance, immune system, internal system and the disease of hematopoietic system etc. that cause because sucking excessive VOC gas in addition also happen occasionally.Long Term Contact and these gases of excessive suction, also can cause metabolic deficiency and genetic disease.Research has proved the nervous system that aromatics and fats hydrocarbon energy loss victimize, chlorohydrocarbons etc. can cause human liver renal damage and slow poisoning, and ketone and based organic solvent pollutant can cause human respiratory tract's inflammation, bronchial astehma and allergic dermatitis, eczema, conjunctivitis etc.
The VOC class material atmosphere pollution pollutant kind of broad sense is various, wide material sources, control and difficulty of governance larger.In industrial environment, VOC material also has a great difference because of solvent kind, volatile matter source difference, is also not quite similar to the harm that operator and atmospheric environment may cause.As furniture, install additional, lacquer spraying waste gas that the workshop section of spraying paint of application etc. produces, wherein pollutant is a large amount of benzene, toluene equal solvent other organic pollution materials that painting process produces, and has stronger toxicity, easily causes very serious injury to human body.Implement spray paint spraying process in, these organic substances are sprayed away as solvent, and a part is adsorbed in the surface for the treatment of coat, play effect of spraying paint and are separately partially suspended among air, and may inhale by operating worker people, enter its respiratory system of people.The benzene that toxicity is very strong, toluene etc. can cause serious injury the respiratory tract of operator, once this type of noxious material reaches finite concentration, more can cause major injury to the central nervous system such as human brain, spinal cord and hemopoietic system, very easily cause workman poisoning, and cause the disease that a series of refractories such as alpastic anemia heal, cause great damage to poisoner.Even if when the organic substance concentrations such as benzene are lower, harmful organic substance gas in environment also can cause certain injury to long-term work operating personnel in the environment, if harmful gas concentration is not high in operator's working environment, workers with long time works in such circumstances, though do not have obvious toxic reaction, but after the long period, occur feeling sick still unavoidably, dizzy, vomiting, the obnubilation even symptom such as neurasthenia, this be all due to nervous system impaired caused by, and the cause of poisoning is all the long-term induced gas breathed containing organic harmful toxic matter.In addition, also injury in various degree can be caused to respiratory tract and retina etc. containing organic lacquer spraying waste gas such as a large amount of benzene, toluene.Therefore very important, very urgent to the improvement of this type of waste gas.
One of mankind's environmental problem urgently to be resolved hurrily has now been become to the improvement of organic gas pollutant (VOCs) in air.At present, substantially can be divided into the purification techniques of VOCs material in air and reclaim and eliminate two large classes, absorption method mainly contains absorption method, condensation method, absorption process and membrane separation process etc.; Null method has the technology such as thermal oxide burning, catalytic combustion, biodegradation, photoelectric catalysis degrading.The method commonly used at present the purified treatment of lacquer spraying waste gas is that Production by Catalytic Combustion Process, adsorption treatment method, photochemical catalytic oxidation, plasma electric are from oxidation etc.Direct burning wherein refers to and is directly heated to uniform temperature to the waste gas containing pernicious gas, under the high temperature conditions, in waste gas, organic gas can react with oxygen in high temperature air, through after a period of time, in waste gas, the organic matter such as benzene, toluene can be burned complete, thus reach the object removing organic exhaust gas.The temperature that direct combustion method needs is higher, keeps higher temperature that the processing cost of waste gas can be made to increase, and there is secondary pollution in various degree sometimes.Production by Catalytic Combustion Process requires lower compared to its ignition temperature of direct combustion method, makes organic gas burning in waste gas at a lower temperature thus realize purification under the effect of catalyst.Catalytic combustion method is at present comparatively conventional lacquer spraying waste gas processing method, but also have that organic exhaust gas concentration is low, burning costly, catalyst easy in inactivation, the problem such as passivation.Treatment by Photocatalysis Oxidation is the most frequently used is at present Titanium Dioxide processing method, this technology utilizes titanium dioxide can produce a large amount of oxygen radical feature under action of ultraviolet radiation, by organic matter in the oxidation process waste gas of oxygen radical, but the oxidation of this technology is sometimes not thorough, there is the problem of secondary pollution.
Absorption method removes organic effective ways in lacquer spraying waste gas, and under the suction-operated of high-efficiency adsorbent, in waste gas, organic gas can constantly to adsorbent transfer, concentration can decline fast, reaches the object effectively removed.Adsorbent declines in efficiency or adsorbs saturated rear needs regeneration process and just can use further.Under the effects such as high temperature, adsorbent organic gas can discharge again, thus reaches the object of adsorbent reactivation.Therefore adsorption treatment is not only a kind of processing method of organic exhaust gas, is also the effective ways that a kind of waste gas concentrates.By absorption and the regeneration desorption of adsorbent, the concentration of organic exhaust gas can to a certain degree be greatly improved, again through burning process etc., not only increase treatment effeciency, due to the raising of organic exhaust gas concentration, release energy in combustion process and also can greatly improve, thus greatly reduce the energy ezpenditure in other combustion processes.
Although the processing method of above-mentioned organic exhaust gas reaches the object of cleaning organic waste gas all to a certain extent, purification efficiency is not high, and usually can only process the waste gas of a certain particular flow rate, and disposal ability is limited, versatility is bad.
