The definition of organic off-gas treatment mixes room of the lacquer that bake characteristic and its processing means

　　Organic off-gas treatment is to point to produce in industry the organic waste gas that produces in the process undertakes adsorption, filter, depurative processing works. General and organic off-gas treatment has formaldehyde the benzene such as xylene of toluene of organic off-gas treatment, benzene is content fourth ketone of organic off-gas treatment, acetone ester of second of acid of organic off-gas treatment, second is off-gas treatment, oily mist organic off-gas treatment, furfural is organic off-gas treatment, styrene, acrylic organic off-gas treatment, colophony organic off-gas treatment, add an agent organic off-gas treatment.

Feature of organic off-gas treatment: Organic waste gas exists commonly combustible explode easily, poisonous and harmful, not dissolve at water, dissolve at, the feature with processing great difficulty. What choose generally when organic off-gas treatment is adsorption of activated carbon of organic waste gas processing law, catalysis burns law, catalytic oxidation law, soda acid counteracts a variety of principles such as law, plasma law. General recommend uses plasma method, because the law has microtherm plasma purify power is high use handy feature.

Method of better organic off-gas treatment is catalytic oxidation purifies a system, off-gas treatment is program careful, layer upon layer purify filter waste gas, function is better. But no matter which kind of plasma are with high pressure discharge is given priority to,should see, produce discharge strike a light, japanese Osaka university on October 2, 1991 16 when, produce plasma to blow up, on the spot scamper is dead 2 people, flesh wound 5 people. Do not advocate in chemical medicine exercise is applied so.

Manufacturer of room of the lacquer that bake about baking lacquer room the method of organic off-gas treatment has a few kinds:

Absorb a law: Choose physics to absorb commonly, soon waste gas introduces absorb fluid to enter purify, wait for absorb the classics after fluid is full to heat, analytic, condensation calls in this law applies to waste gas of big tolerance, low temperature, low pH indicator, but need equipment to heat analytic call in equipment, equipment bulk is big, contributive taller.

Burn directly law: Apply light the fuel of assist a ruler in governing a country such as gas or fuel to burn, heat gas mixture, make harmful material issues differentiation to be harmless material in high temperature action this law craft is brief, contributive small, apply to the waste gas of high concentration, small wind force, but taller to requirement of safe skill, operation.

Direct and adsorptive law: Activated carbon of classics of organic waste gas is adsorptive, can amount to the purifying rate of 95% above, equipment is brief, contributive small, but activated carbon is replaced frequent, increased to assemble and unassemble, carry, replace wait for work program, bring about operation expenses to increase.

Adsorptive – call in law: Have machine waste gas with adsorption of fiber activated carbon, getting close to full hind with backflushing of overheat water vapour, undertake this law requirement supplies desorption second birth necessary vapour quantity.

Adsorptive – catalysis burns law: This law generalized adsorptive law and catalysis to burn the interest of the law, choose new-style and adsorptive material (beehive shape activated carbon) adsorptive, hot air introduces to undertake after getting close to drink is mixed desorption, analytic, the waste gas after desorption introduces catalysis to burn the bed burns without blaze, purify its completely, heat up gas to be applied circularly in the system, drop greatly specific power consumption. This law has operation capital of smooth and steady firm, contributive province, exercise is low, repair handy wait for a feature, apply to off-gas treatment of large wind force, low pH indicator, it is now home handles the method with organic adepter, useful waste gas.

Condensation calls in law: Guide organic waste gas into condenser classics adsorption directly, absorb, solution board, respectively, can call in valuable organic matter, this law applies to chroma of organic waste gas tall, temperature operating mode of hidebound of low, wind, demand is accessary frozen plant, principal apply at pharmacy, change exercise job, presswork the enterprise is chosen lesser.
