Alloy chlorination reaction kettle for production of chlorinated polyethylene

Abstract

The invention provides an alloy chlorination reaction kettle for production of chlorinated polyethylene, which is capable of effectively eliminating reaction temperature delay during synthesis of the chlorinated polyethylene, and is short in production cycle, high in efficiency, low in labor intensity and energy consumption and easy in implementation of automated operation.

Description

technical field [0001] The invention relates to a chlorinated polyethylene production equipment, in particular to a device for synthesizing chlorinated polyethylene through chlorination reaction. Background technique [0002] At present, in the production process of chlorinated polyethylene, domestic chlorinated polyethylene manufacturers use 5m 3 、6.3m 3 or 12.5m 3 Glass-lined reactor, this type of reactor has a small volume, small batches of products, and unstable performance; the glass-lined reactor uses an enamel baffle inserted into the reactor as a temperature measurement point, and the glass-lined heat insulation effect is good , the reaction temperature lags seriously. During the heating process, the temperature can lag by 2°C-5°C, resulting in unstable temperature control and large fluctuations in product quality; The leaves are small, the material rotates in a circle in the reactor, there is no up and down movement, and the stirring intensity is weak, resulting ...
