Unit is the flow area that monolithic structure and each coating cloud capture unit cover air；This method can greatly improve coating cloud
Trapping carrying capacity and separating effect of the capturing device to coating cloud.
For the separation and collection of coating cloud, the patent of Cai Qi et al. applications《A kind of separation of paint slag, regenerative system and method》,
A kind of paint slag separation of the disclosure of the invention, regenerative system, which can turn waste into wealth, and also avoid to the secondary of environment
Pollution.
Although foregoing invention can well filter the coating cloud in VOCs, the coating cloud capturing device of Zhou little Can inventions is one
The product that secondary property uses needs replacing into new coating cloud capturing device after coating cloud capturing device reaches the trapping receiving limit, and
It could not be it is further proposed that being collected to coating cloud after filtering；Coating cloud process meeting is being collected in the invention of another aspect Cai Qi et al. applications
A large amount of waste water is generated, and since the boiling point of VOCs is at 90 DEG C or so, in paint slag drying course, the VOCs painted in slag can be prior to
H2O volatilizees, and certain secondary pollution is caused to environment.
