Which a few kinds does the processing principle that equipment of industrial off-gas treatment handles have?

Be aimed at the waste gas of different type, need uses different method to undertake equipment of industrial off-gas treatment undertakes handling, and the method that equipment of different industrial off-gas treatment uses also is different, so in what is the principle that handles waste gas put to distinguish?

1. Plasma of microtherm plasma low temperature is the material after afterwards solid state, liquid state, gaseous state the 4th condition, catch fire when what extra voltage achieves gas when voltage, aeriform element by puncture, generation includes all sorts of electron, ion, atom and freedom base inside mixture body. In discharge process although electronic temperature is very high, but heavy particle temperature is very low, whole system presents microtherm position, call microtherm plasma so. Contaminant of microtherm plasma degradation is to use the contaminant function in the active particle such as these high-energy electrons, freedom radical and waste gas, make contaminant element happens inside cutty time decompose, all sorts of reaction of intercurrent unripe follow-up in order to achieve the goal of degradation contaminant.

2. The solid state filling with the tailor-made backfill inside tower of reaction of technology of combustion of catalysis of much medium of technology of combustion of much medium catalysis, 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. Suitable scope: Suitable scope is wide, apply to processing especially big tolerance, medium waste gas of tall pH indicator, have very good purify rate to hydrophoby pollutant. 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.

3. Water absorbs law water to absorb Farley to use some of some material Yi Rong in 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.

4. Dilute diffuses law dilute diffuses the law will have stink ground gas to be 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. Say equipment of industrial off-gas treatment can use different method to undertake handling according to different waste gas so, assure its good performance thereby.
