Vinyl chloride processing equipment

Abstract

The invention discloses vinyl chloride processing equipment. The equipment includes a water separator and a compressor. The equipment also includes a fiber demister. An air inlet of the fiber demister communicates with the water separator. An air outlet of the fiber demister communicates with the compressor. The vinyl chloride processing equipment provided by the scheme is additionally provided with the fiber mister between the water separator and the compressor. The fiber demister is used for removing mist carried in vinyl chloride so as to reduce the mist entering the compressor to reduce the oil emulsification of the compressor and ensure the normal operation of the compressor. Meanwhile, the water carried by the vinyl chloride into a distillation process is reduced, the vinyl chloride monomer is prevented form self-polymerization to block distillation equipment, the generation of acidic matters can be reduced, and corrosion of the distillation equipment is slowed down.

Description

technical field [0001] The invention relates to the technical field of vinyl chloride processing equipment, in particular to a vinyl chloride processing equipment. Background technique [0002] The vinyl chloride process includes mixed dehydration, synthetic conversion, water washing, alkali washing, compression and rectification. Specifically, the crude vinyl chloride formed after mixed dehydration and synthetic conversion is demercurized and then enters the three-in-one water-washing combined tower, removes residual trace HCL through the alkali-washing tower, and then enters the VC gas cabinet or removes part of the entrainment through the pre-machine cooler. liquid, and then pressurized to 0.5-0.6MPa by a screw compressor, and then the entrained water and oil are removed by the after-machine cooler, and sent to rectification. [0003] Since the screw compressor has a high requirement on the water content of vinyl chloride, if the water content in vinyl chloride is high, ...

AI Technical Summary

Problems solved by technology

[0003] Since the screw compressor has a high requirement on the water content of vinyl chloride, if the water content in vinyl chloride is high, when the screw compressor compresses the vinyl chloride, the oil in the screw compressor will be emulsified, although there is a device in front of the screw compressor Water separator, but the water separator can only simply separate the water, and a large amount of water foam will be entrained in the vinyl chloride passing through the water separator, and the water foam entering the screw compressor will also emulsify the oil of the screw compressor; and the vinyl chloride Carrying water into the rectification process will cause the vinyl chloride monomer to undergo self-polymerization reaction, block the rectification equipment, and produce acidic substances at the same time, corroding the rectification equipment
