　　A lot of factories and enterprise have spray paint room and house of the lacquer that bake, they can produce paint grain content and waste gas in spray paint working procedure, cause very great harm to human body. Accordingly, of these organic waste gas discharge without the organization belong to environmental protection not to amount to mark, it is environmental protection bureau fathers one of phenomena that check, so the enterprise wants environmental protection amounts to mark, be about to undertake waste gas is collected there is an organization to discharge after purifying processing.

Want to accomplish organic exhaust emission to amount to mark, be about what to understand is room of environmental protection spray paint. Room of environmental protection spray paint is to show in a room object of opposite filter spray paint undertakes spray paint, indoors spray paint, because be in outdoor environment,be spray paint, mix dust easily into paint, reduce spray paint quality.

Environmental protection branch asks spray paint room installs purifying device, if did not install purifying device, or the enterprise with processing abnormal unit, in receive ” inform a book ” hind stop spray paint to work instantly; Had installed purifying device, need administers establishment to undertake to the waste gas such as activated carbon comprehensive examination, newer, ensure equipment moves normally, reach environmental protection level.

The classification of room of environmental protection spray paint:

1. Will divide by air current direction, can divide issue strong pattern spray paint for room of crosscurrent type spray paint, flank room and leave room of strong pattern spray paint completely 3 kinds;

2. By heat means will divide, can divide heat for room of derv spray paint, report spray paint room, vapour heats room of spray paint room, spray paint of infra-red room of the lacquer that bake, useless engine oil;

3. By Qi Wu processing means is divided, can divide mix for room of dry type spray paint wet spray paint room, use at present more is room of dry type spray paint, so system of filter of operation personnel opposite should check hand-in-hand travel to change regularly, can affect quality of the lacquer that bake otherwise.

6 kinds of common spray paint rooms off-gas treatment law:

1. Box of water type environmental protection off-gas treatment law: The advantage is water natural resources is gotten easily, the course filters, can answer after precipitation with, quite big limit reduces the waste of water natural resources, because efficiency is tall, often serve as the pretreatment of off-gas treatment.

2. Box of activated carbon environmental protection off-gas treatment law: Activated carbon of organic gas classics is adsorptive, with heat air undertakes desorption second birth after activated carbon is saturated.

3. Condensation absorption method: the condensation after direct condensation or adsorption condense waste gas, condensate reclaims via depart valuable organic matter. This law applies to chroma tall, temperature off-gas treatment of hidebound of low, wind.

4. Absorb a law: Physics absorbs a law is to choose appliance to have lesser volatile liquid absorbefacient, it has taller affinity with constituent be absorptioned, the classics after absorbing saturation heats the reuse after analytic refrigeration.

5. Act of the water that do not have pump + box of activated carbon environmental protection + law of off-gas treatment of equipment of processing of catalysis of Uv smooth oxygen: Apply to the organic waste gas that high temperature Gao Nong spends to administer, do not apply to the organic waste gas of low density, large wind force to administer.

6. Microtherm plasma law: Suitable scope is wide, purify efficiency tall, the much constituent that applies to other method to be handled hard especially effluvial, organic waste gas, equipment covers an area of an area small; Moving charge is relatively inferior; Reaction is sharp, stop very rapid, along with with follow.

Environmental protection amounts to mark is every production company runs the business that should accomplish normally, the organic waste gas with spray paint unripe house property is right the harm of human body is very great, also can cause certain effect to the environment. Accordingly, spray paint room off-gas treatment law is the method that every production company should master.
