Abstract

The invention discloses an environment-friendly dual-channel purification treatment device for exhaust of a paint spraying room. The device comprises a piston plate, a purifying shell and an electrostatic dust removal net, wherein an exhaust conveying pipe is connected to the middle of the left end of the purifying shell, a partition board is connected into the purifying shell, a vent hole is formed in the middle of the partition board, a separation board is arranged in the vent hole, an upper gas collection pipe is arranged at the upper part of the separation board, upper filter cotton is arranged above the upper gas collection pipe, an upper filter net is arranged above the upper filter cotton, and an upper purifying channel is formed in the purifying shell and above the upper filter net; and a lower gas collection pipe is arranged at the lower part of the separation board, lower filter cotton is arranged below the lower gas collection pipe, a lower filter net is arranged below the lower filter cotton, and a lower purifying channel is formed in the purifying shell and below the lower filter net, the partition board is mounted at the left end of the separation board, and the piston plate is mounted between the partition board and the purifying shell. According to the environment-friendly dual-channel purification treatment device, the purifying effect of dust-containing paint fog in the paint spraying room is improved; and by flexibly changing the upper purifying channel and the lower purifying channel, the maintenance is convenient, and the treatment of paint mist is not influenced.

Description

technical field The invention relates to the technical field of environmental protection equipment, in particular to an environment-friendly double-channel purification treatment device for exhaust gas in a spray painting room. Background technique Auto parts spray paint, generally use baking paint. In the automobile manufacturing plant, the frame and shell are welded, and the next process is painting. The forms include ordinary paint, metallic paint, and pearlescent paint. Automobile painting process: scraping putty, grinding, painting, etc. In the production and manufacture of automobiles, it is necessary to use various metal parts to connect and fix the structures. In order to slow down the corrosion and aging of metal parts, it is necessary to spray paint on the surface. The accessories are placed on the frame and put into the spray booth for collective painting, thus increasing the service life of the surface of the auto parts. Painting is an important link in the ...
