AI Technical Summary
In existing technologies, vinyl chloride residues remaining before the maintenance or shutdown of vinyl chloride production units cannot be effectively recovered, leading to raw material waste, environmental pollution, and safety hazards. Furthermore, direct discharge of vinyl chloride poses serious risks.
The vinyl chloride negative pressure recovery system uses a water ring vacuum pump to create a negative pressure environment. Combined with a condenser group and a DCS control system, it achieves closed-loop recovery and automated protection of vinyl chloride. This includes the combined use of end connection pipes, instrument shut-off valves, negative pressure tanks, water ring vacuum pumps, condenser groups, and VCM storage tanks to ensure comprehensive recovery and safe operation.
It achieves efficient recovery of vinyl chloride, reduces raw material waste and environmental pollution risks, improves production economic efficiency, reduces safety hazards, and the recovery rate can reach over 98%.
