Surface painting waste gas treatment program - treatment equipment

Automobile manufacturing industry is a high-pollution industry, especially the automobile surface painting will produce a lot of exhaust gas, in the context of modern global promotion of environmental protection, the automobile manufacturing industry has received more attention and attention, but also a lot of problems to be solved, a lot of process technology to be optimized and improved, automobile manufacturing surface painting exhaust gas generation sources are what?

The surface painting workshop is the high energy consumption and high pollution in the automobile manufacturing industry, and the painting room is the most important pollution point, but also the main source of air pollution, the treatment of the exhaust gas of the painting room is an imminent problem to be solved.

If you want to solve a problem, you must first know where the problem is, the exhaust gas mainly comes from the paint mist and the vapor of the solvent volatilization. In particular, solvent vapor is a highly toxic gas substance, the solvent content of general liquid coatings accounts for 50% to 60% (nitro coatings and even up to 80%), these solvents in the coating all volatilized into gas, and the main source of exhaust gas generated in the coating:

Spray booth exhaust:

In order to maintain the working environment of the painting room, the ventilation speed of the painting room should be controlled at 0.30 ~ 0.60m/s. General spray booth contains paint mist dust produced by overspray. The particle size of this dust (paint droplets) is 20 ~ 200um, no large wind can not fly far away, and the role of the drying room is to make the coated material after painting, drying or forced drying before, so that part of the solvent in the coating film volatilized to form a good coating film.

In this exhaust contains only solvent vapor and almost no paint mist.
