Trichlorethylene separator

Abstract

The invention discloses a trichlorethylene separator, which comprises a still body, the still body is connected with a intermittent tower, and the inside of the still body is provided with a partition separating the mixed gas and the rectifying gas, and the partition It communicates with the condenser, the intermittent tower is connected with a collection pipe, and the intermittent tower is connected with two adjustment parts for adjusting the position of capturing trichlorethylene, and the two adjustment parts are connected with a collection plate, and the collection plate is located at Inside the batch tower, the waste mixture produced in the trichlorethylene production process of the present invention is distilled through the existing distillation pot, and the rectified gas generated during the distillation process is introduced into the set partition through the condenser to exit. Reduce the mixing of rectified gas and undistilled mixture gas. At the same time, after a period of distillation, adjust the collection position of the collection plate through the set adjustment member to reduce the collection of other mixture gases with distillation during the collection process.

Description

Technical field [0001] The present invention relates to the technical field of chemical devices, in particular a trichlorethylene separator. Background technique [0002] In the production of trichlorethylene, crude trichlorethylene is removed from the low boiled tower. This part of the acidity of the low boiling matter is high, the moisture content is high, which is dark yellow. It is the waste in the production process. The low-boiling waste component is known by test analysis, and the waste composition produced in trichloroelectric production is: Dichloro Ethylene mass fraction 1.82%, dichloroethane mass fraction of 2.38%, trichlorethylene mass fraction of 85.85%, trichloroethane mass fraction 1.61%, tetrachlorethylene mass fraction 6.87%, tetrachlorose mass fraction of 0.43%, pentachlorine Ethylene moral fraction of 0.001%, hexachloroethane mass fraction of 0.01%, acidity 4.5 ~ 28 x10 -4 Like HCL, the same as the same), aquatic mass fraction 4.2-18.3) x10 -5 The mass fraction...

AI Technical Summary

Problems solved by technology

[0003] Currently, in the process of repeated rectification, the gaseous waste with low boiling point is condensed and collected at the top of the intermittent tower, and the condensed low-boiling point gaseous waste is condensed into the distillation pot through the condenser, and the condensed low-boiling point gaseous waste is When the mixed gas in the still is not completely evaporated, the low-boiling point gas waste condensed into the still is mixed with each other, so that the trichlorethylene in the gas mixture is mixed with fine water containing water. Distilled gas, so that in the capture process of trichlorethylene, trichlorethylene mixed with rectification water seal is captured, which is not conducive to the capture purity of trichlorethylene. At the same time, in the multiple rectification process, the waste gas produced It is gradually absorbed by distillation, and the waste gas with a boiling point similar to trichlorethylene is easily captured at the capture device of trichlorethylene. impure, for which we propose a trichlorethylene separator
