VOCs disposal

Automobile Manufacturing Coating Workshop VOCs Disposal

Main Source

VOCs emissions in automobile surface coating process account for more than 90% of the manufacturing process. Air pollutants are emitted in the process of electrophoresis primer drying, middle coating, paint and varnish spraying and drying in automobile production, 50% of which comes from medium coat, color coat and varnish, 30% from cleaning solvent. Due to the high curing rate and nonvolatility of PVC and protective wax, the pollutant emission from the body sealing and wax spraying process is relatively small. In the process of coating, paint and varnish operation, about 80~90% of VOCs exhaust gas is emitted in the spray booth and leveling chamber, and 10~20% is emitted in the drying room.

Technical Route

1. RTO/TO: aimed at the high temperature, high concentration and small air volume waste gas generated by electrophoresis, middle coating and finish drying room.

2. KPR+RTO: aimed at the room temperature, low concentration and large air volume waste gas generated by electrophoresis, middle coating and finish coating workshop.
