[0002] At present, most of the tail gas with solvents in the coating industry uses traditional treatment processes. For example, it is concentrated by a zeolite wheel and then incinerated by RTO. This consumes a lot of energy and emits a large amount of carbides. At present, the multi-component solvent tail gas generated by the coating workshop enters the tail gas recovery equipment through the exhaust system for recovery, and then the recovered tail gas is discharged in compliance with the standards. When the tail gas enters the tail gas recovery process, the gas is usually mixed with solid impurities. In the prior art, it is generally filtered through a filter net.
