（1）The collection of gas：Gas gathering mask 1, the centrifugal blower 6 that gas gathering mask 1 is connected is arranged in emission point in the exhaust gas centralized in workshop
Air quantity be 5000~20000m3/ h, negative pressure absorbing exhaust gas to spray equipment;
（2）Spray cleaning：Exhaust gas increases gas humidity via the coating cloud in spray equipment removing exhaust gas, forms exhaust gas B；
（3）Biological cleaning：Exhaust gas B passes through the new old generation of the microorganism on filler in biological purification plant via biological purification plant
Pollutant in organic exhaust gas is converted to inorganic matter and microbial cell matter by the effect of thanking, and forms exhaust gas C；
（4）Exhaust fume catalytic：Exhaust gas C reduces shape after VOC ingredients via 5 heatable catalytic of gas combustion mechanism, filtration residue organic matter
It is discharged via air at exhaust gas D.
In step（3）Or step（4）Afterwards, it is also associated with the inner loop pipeline that the control of controller 12 opens and closes, to control exhaust gas C
Or exhaust gas D enters next work step or returns to wind turbine and restart step（1）Cycle.
In the production link of related factories, needed during paint use in proportion with isobutanol, anti-plain boiled water and open grease into
Row allotment, paint process carry out in paint room, and paint room is provided with gas gathering mask 1 and is collected to illegal a small amount of organic exhaust gas
It is directly arranged afterwards to outdoor.
Painting process uses air spray finishing, and by deployed paint spraying to shell, aerial spraying is empty using compression
Gas flows through spray tip hole and forms negative pressure, and negative pressure makes paint vehicle be sucked from suction pipe, sprayed through nozzle, forms coating cloud, coating cloud injection stream
Uniform paint film is formed on by covering with paint component surface.
In specific works, waste water station exhaust gas is mainly the organic gas to volatilize in spraying coating line waste water.Spray column acts on
In removing the coating cloud in removing exhaust gas, while increasing gas humidity；Biological packing tower then utilizes bioanalysis, by being filled out in attachment reaction device
Bacteria metabolism on material is acted on is converted to inorganic matter and microbial cell matter by the pollutant in organic exhaust gas.Biological oxygen
Change method, which handles organic exhaust gas, has equipment simple, is not necessarily to additional aid in treatment medicament, and construction cost is relatively low；It is easy to operate, energy consumption
Low, operating cost is small；High treating effect, non-secondary pollution have the advantages that stronger security performance.
Wet-type spray deduster removal paint particles dominant mechanism is mainly concerned with inertial collision, interception function, diffusion work
With and gravity etc., shower water is to recycle, but certain using that can contain in clarifier after a certain period of time and recirculated water
The Oil Paint Slag of amount, it is therefore desirable to be cleared up, recirculated water is replaced.
In order to improve the treatment effect of water spray deduster, need to add the professional eliminating smell agent of suitable spray painting in shower water,
The eliminating smell agent can effectively remove the organic exhaust gas such as benzene,toluene,xylene, can reduce subsequent spray biology.
This project exhaust gas executes Guangdong Province's provincial standard after processing《Air Pollutant Emission limit value》(DB44/27-
2001) the second period secondary discharge standard in.Leading indicator is as shown in table 1-1：
Table 1-1 discharge of major pollutant standards
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although
Present invention has been described in detail with reference to the aforementioned embodiments, for those skilled in the art, still can be right
Technical solution recorded in foregoing embodiments is modified or equivalent replacement of some of the technical features.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in the protection of the present invention
Within the scope of.
