The working method of equipment of industrial off-gas treatment

Just began period of reforming and opening at the outset, we develop industrial construction energetically, hardly those who consider pair of environments is destroy, what pollute as industrial waste gas nowadays now is serious, our country also begins to take the processing to industrial waste gas seriously, and had issued article for many times, come to those who administer industrial waste gas arrange an issue, so current what does the method of country’s most common industry off-gas treatment have? Below grand richIndustrial off-gas treatmentEquipment manufacturer gives everybody introduction, the word that have fun at can look.

　　One, dilute diffuses law

Will stink ground gas is discharged through chimney to atmosphere, or with without foul air dilute, reduce effluvial material concentration in order to reduce a stink. Suitable scope: Apply to the effluvial gas that handles medium, low pH indicator to the organization is discharged. Advantage: Charge low, equipment is simple. Defect: Easy be deceived resembles a condition to restrict, effluvial matter still exists.

　　 2, water absorbs a law

Some of some material easy dissolve in using bad smell the character at water, make bad smell composition is contacted with water directly, dissolve thereby achieve deodorization goal at water. Suitable scope: The water-solubility, effluvial gas that has constituent source. Advantage: Craft is simple, management is convenient, low yield of equipment movement charge gives birth to pollution 2 times, need to undertake handling to catharsis fluid. Defect: Purify efficiency low, answer to be used jointly with other technology, mellow to sulfur, the processing effect such as fatty acid is poor.

　　 3, aeration type law of activated sludge deodorization

Will effluvial material arrives dispersedly with aeration form in the mix up juice that contains activated sludge, the microbial degradation that grows through suspension is effluvial material, suitable scope is wide. Advantage: After activated sludge passes domestication, to exceeding the effluvial part that ultimate load measures, purify rate can amount to 99.5% above. Defect: Get the limitation of aeration intensity, the application of this law still has certain limit.

4, technology of combustion of much medium catalysis

　The solid state filling with the tailor-made backfill inside reaction tower, filling is in-house answer match much medium activator. Filling layer is crossed below the effect that citing fan when effluvial gas, with show the fluid with ejective shape of mist of disperse the internal heat with sudorifics through tailor-made nozzle photograph answer matchs oxidizer to be contacted adequately in surface of solid photograph filling, fall in the catalysis of much medium activator, the contaminative factor with effluvial medium gas is decomposed adequately. Advantage: Cover an area of small, investment is low, management of moving cost low; is convenient, leave to be used namely namely. Defect: Impulse withstand bear, chroma of not easy contaminant and temperature change are affected, need to use up the drug of certain amount.

　5, cooling tower handles a way

　This also is current till the method of processing waste gas with our country most wide application, probably the principle passes cooling tower when waste gas namely when, meeting and the absorption with cooling in-house tower the contact with sufficient fluid, absorb fluid to be able to happen with the harmful gas in industrial waste gas a series of reaction, through a series of after reaction, the gas of eduction is clean gas, such processing method is simple, and the result is very right, need relatively simple equipment to be able to be finished only, and the fee of waste gas processing of manufacturer also can be reduced greatly.

　 6, technology of AOP advanced combustion

　　Technology of AOP advanced combustion is the law of classical and chemical oxidation in handling a technology to the tradition, in a kind of of the emerge as the times require on the foundation of reform new technics, LTAOP of dragon peaceful environmental protection uses AOP technology to handle effluvial gas, hydroxyl is free base after reacting with organic matter in antiseptic, disinfection, deodorization, its are final resultant is CO2, H2O and harmless carboxylic acid. Oxidation activator is precious metal oxide, oxidizer falls in the action of activator, the hydroxyl with generation extremely strong oxidisability is free base (OH) , these freedom base dissoluble almost all and organic matter, the hydrogen that contains its (H) and carbon (C) oxidation becomes water and carbon dioxide. Outside dividing waste time of power consumption, water, do not use up other raw material, do not bring pollution 2 times, need not handle 2 times.

　7, off-gas treatment keeps apart a law

　It is to pass special type to filter material, buy is put at process of the platoon outside waste gas, via mechanical segregation, achieve waste gas to administer the effect thereby. Advantage: Tall to efficiency of processing of smoke of mist form gum, without technical requirement, the operation is simple. Defect: Cannot effective purify organic matter, wind block is large.

　 8, wait to oxidize from microtherm catalysis law

The 4th kind of except solid state, liquid state, gaseous state condition that plasma is corporeal existence, have macroscopical degree inside electrically neutral with tall conductivity. Particle of many active electron, ionic, excitation state and photon are contained to wait in plasma. These active particle and aeriform element touch the result of whisk, · of freedom radical O, OH · , HO2 mixes the strong oxidisability with many generation the member of O3; organic matter with very powerful oxidisability is collided by high-energy electron, be aroused to reach atom be good at rupture and form small fragment base group or atomic;O · , OH · , HO2, O3 with invoke element of atomic, organic matter, base the reaction such as round, freedom radical, make degradation of oxidation of organic matter element is CO, CO2 and HO2 finally.

　　 The working method of equipment of industrial off-gas treatment

Advantage: Extensive applicability, agree with handle low density ( ) , the harmful gas with virulent foul play, made up for the blank that other technology cannot handle. And the operation is simple.

Defect: Alone microtherm plasma technology still has its defective place when handling harmful gas, be like cannot complete thoroughly harmful gas translate into harmless gas, by-product is more; and in oxygen taller; takes off the ozone; specific power consumption with the many generation below plasma except efficiency lower.
