What does the processing technique of waste gas of volatile organic industry have after all?

Off-gas treatment of volatile organic industry is to show boiling point issues saturated vapour pressure to exceed 133.3Pa in 50-260 ℃ , room temperature easy volatile organic compound. Its bases is hydrocarbon kind, sulfide, ammonia, can generate O3 to be able to form photochemical smog with the NO2 reaction in atmosphere, and be accompanying is worn peculiar smell, effluvial send out in air, have stimulative effect to the person’s eye, bazoo and respiratory tract, wait to heart, lung, liver splanchnic reach neurological happening ill effect, some are influence human body the abnormal reaction source of certain organ and airframe, cause even acute and chronic and toxic, can cause cancer, cause mutation, can cause crop reduction in production at the same time. No time to delay of off-gas treatment of volatile organic industry, what method of off-gas treatment of what organic industry suits volatile gas to have so?

1 liquid is absorbed deal with technology

In project of processing of industrial off-gas treatment, the liquid absorbs a law is one of the most commonly used methods. This law can remove gaseous contaminant not merely, still can reclaim a few useful material, this technology is used low volatilize or do not volatilize the liquid is absorbefacient, all sorts of constituent in using industrial off-gas treatment through absorbing unit are in the solubility in absorbefacient or the difference with chemical characteristic responses, make the harmful constituent in industrial off-gas treatment is absorbed by absorbefacient, achieve the goal that purifies industrial off-gas treatment thereby

2 biology deal with technology

Use process of organic biology degradation at organic industry off-gas treatment purify dealing with is just begin in last few years as a result of microbial all have stronger, faster adaptability to all sorts of contaminant, can regard metabolization bottom as content its and degradation, change. Accordingly, compare with photograph of traditional technology of organic industry off-gas treatment, biology deals with the technology is had deal with good, investment reachs the result moving charge is low, restful the gender is good, pollute without 2, easily the advantage such as management; In the meantime, because biology of industrial off-gas treatment deals with,the second birth of absorbefacient can pass the microbial action in absorbefacient to come true directly, and do not need to be changed like manage absorb and adsorptive in that way special device, simplified thereby technological process and industrial equipment, reduce moving operation cost.

Oxidation of 3 smooth catalysis deals with technology

Law of smooth catalysis oxidation is the contaminative processing new technology that is taken seriously in recent years increasingly. Can achieve 90 ％ ～ to VOCS degradation rate 95 ％ . This technology is to show in certain wavelengh illumination falls, the smooth catalysis that uses activator is active, make sorbent produces oxidation in the VOCS of its surface reductive reaction, become organic matter oxidation finally CO2H2O and matter of inorganic young member. Smooth catalysis oxidation is had alternative, reaction condition is gentle (normal temperature, often press) activator is avirulent, specific power consumption is low, the operation is handy, the value is relatively inferior, generate without by-product, the activator after using is used circularly after second birth of usable physics and chemical method, all provide to almost all contaminant purify the advantage such as ability.

Plasma of 4 low temperature deals with technology

Microtherm plasma technology says to be not balance plasma technology again, below the action of adscititious electric field, produce many high-energy particle through medium discharge, high-energy particle and organic contaminant element produce a series of complex plasma to react physico-chemically, thereby will organic corrupt
