The technical characteristic of off-gas treatment equipment

Off-gas treatment equipment basically is to use different technology skill, the course calls in or purify cuts the harmful part that arranges tail gas, reach place of dimension retaining ring, purify airy equipment of a kind of environmental protection. Off-gas treatment basically is pressing with a finger one kind when gas of soot of the content of grain of dust of example of industrial waste gas that breaks out to industrial place, flue gas, peculiar smell, poisonous and harmful gas stops to deal with purifies gimmick.

Common off-gas treatment has off-gas treatment of processing of peculiar smell of soot off-gas treatment, dust off-gas treatment, organic off-gas treatment, waste gas, soda acid to wait. Adsorptive law includes: Direct and adsorptive law, water absorbs law, adsorption – catalytic combustion law, direct combustion law, catalytic combustion law, absorb a law. The method of a few kinds of off-gas treatment of off-gas treatment equipment:

1, adsorptive law: The adsorptive function that handles sorbent makes effluvial material is communicated by aeriform photograph move to solid. Advantage: Apply to processing low density, gao Jing turns the effluvial gas of the request, purify power very tall, can treat form of much constituent evil bad smell. Blemish: Adsorptive charge is precious, second birth is harder, the effluvial gas that requests to wait for processing has inferior temperature He Hanchen to measure. This kind of method is appropriate at in the off-gas treatment of small wind force, and the operation is simple, the effect is good, contributive charge is reasonable.

2, water absorbs law principle: Off-gas treatment equipment applies some of some material easy dissolve in bad smell the character at water, make bad smell composition is contacted with water directly, dissolve next arrive at deodorization purpose at water. Suitable scope: The water-solubility, effluvial gas that has constituent source. Advantage: Craft is simple, conduction advantage, small show effect of facility work expenses is polluted 2 times, need to stop to handle to cleanse fluid. Blemish: Purify power low, answer to be applied with other craft union, mellow to sulfur, the processing effect such as fatty acid is poor. This kind of method is simple and reliable, contributive province, processing wind force does not accept an obligation.

3, condensation law is to will abandon air temperature to descend, make harmful material condensation, condense and with waste gas space, arrive at depurative purpose, this kind of method is contributive big, specific power consumption is tall, do not suit to handle the waste gas of large wind force.

4, combustion law cent is direct combustion law and catalytic combustion law. Effluvial below high temperature material and fuel enrage sufficient mix up, finish complete combustion. Off-gas treatment equipment applies to the flammability gas that handles high concentration, persnickety volume. Advantage: Purify power tall, effluvial material is changed to synthesize by complete oxygen. Blemish: Equipment is perishable corrode, consume fuel, processing capital is tall, easy form pollution 2 times. Direct combustion law is to will contain the waste gas of harmful material to send burner burn-up, catalytic combustion is the harmful material in having waste gas of the combustion below activator assist a ruler in governing a country. Combustion law is contributive also big, specific power consumption is tall, do not suit to handle the waste gas of large wind force, the environmental risk that existence fit pollutes 2 times.
