Device for continuously separating hexachloroethane in tetrachloroethylene solid waste

Abstract

A device for continuously separating hexachloroethane in tetrachloroethylene solid waste. The device comprises a base, a speed regulating motor, a driving motor and a strip groove; the outer side wallof the strip groove is covered with a heating jacket, and the opening of the strip groove is sealed by a sealing cover body; a speed regulating shaft is rotatably disposed in the strip groove; a first spiral blade extending along the axial direction is arranged on the speed regulating shaft, and the first spiral blade is in clearance fit with the groove wall of the strip groove; a feeding vertical pipe is fixed at one end of the sealing cover body, and a tapered feeding hopper is connected to the upper end opening of the feeding vertical pipe; a driving shaft is rotatably arranged in the feeding vertical pipe; the driving shaft is provided with a second spiral blade extending along the axial direction; the second spiral blade is in clearance fit with the inner wall of the feeding verticalpipe; the other end of the sealing cover body is provided with an exhaust port for connecting with a material steam trap; the bottom of the strip groove is provided with a discharge pipe; and the discharge pipe is located below the other end of the first spiral 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.
