Device for Continuously Separating Hexachloroethane from Perchlorethylene Solid Waste

Abstract

A device for continuously separating hexachloroethane from tetrachlorethylene solid waste, including a base, a speed-regulating motor, a driving motor, and a strip groove. The outer wall of the strip groove is covered with a heating jacket, and the opening of the strip groove is Sealed by the sealing cover, a speed regulating shaft is rotatably arranged in the strip groove, and a first helical blade extending in the axial direction is arranged on the speed regulating shaft, and the first helical blade cooperates with the groove wall of the strip groove to seal One end of the cover body is fixed with a feed vertical pipe, and the upper opening of the feed vertical pipe is connected with a tapered feed hopper. A drive shaft is rotatably arranged in the feed vertical pipe, and a first axially extending shaft is provided on the drive shaft. Two helical blades, the second helical blade is matched with the inner wall of the feed vertical pipe, the other end of the sealing cover is provided with an exhaust port for connecting with the material steam trap, and the bottom of the strip groove is provided with a discharge pipe, The discharge pipe is located below the other end of the first helical blade.

Description

technical field [0001] The invention relates to the field of recovery and utilization of hexachloroethane, in particular to a device for continuously separating hexachloroethane from tetrachlorethylene solid waste. Background technique [0002] The solid waste generated in the production process of tetrachlorethylene contains a large amount of hexachloroethane. Hexachloroethane is one of the most toxic chlorinated hydrocarbons and has a toxic effect on the central nervous system of the human body. Therefore, it is necessary to recycle the hexachloroethane in solid waste. Usually, the separation and recovery of hexachloroethane in tetrachlorethylene solid waste is carried out intermittently by using a reactor to achieve the purpose of recycling hexachloroethane. However, in the process of separating hexachloroethane in the reactor, the intermittent reaction time is long, and the hexachloroethane in the solid waste of tetrachlorethylene cannot be continuously separated, the s...

AI Technical Summary

Problems solved by technology

However, in the process of separating hexachloroethane in the reactor, the intermittent reaction time is long, and the hexachloroethane in the solid waste of tetrachlorethylene cannot be continuously separated, the separation efficiency is low, and the work environment is polluted when feeding and discharging, which is not conducive to work.
