Chlorinated paraffin raw material pretreatment equipment

Abstract

The invention relates to chlorinated paraffin raw material pretreatment equipment. The chlorinated paraffin raw material pretreatment equipment is characterized in that a primary cyclone separator anda secondary cyclone separator are connected with a vapor-phase pipe and a paraffin oil raw material inlet of a salt acid finished product tank through multiple stages of control kettles, and are sequentially connected with a primary falling film absorption tower, a secondary falling film absorption tower, an oil acid extraction tower, a diluted acid circulation tank, and a diluted acid distributor to form a circulation loop; the multiple stages of control kettles are connected with a primary filler tower, a secondary filler tower, a ternary filler tower, a primary absorption water tank and asecondary absorption water tank. The chlorinated paraffin raw material pretreatment equipment has the advantages that the paraffin oil raw material in a chlorinated paraffin production line is firstlyused as an absorbent before entering the multi-stage reaction kettle production line, participates in the treatment of tail gas, and then is used as the raw material of the production line to be used; the chloride gas in the tail gas can be fully absorbed, the byproduct of hydrochloric acid can be prepared when the chloride gas passes through the absorption water tank in the treatment process ofthe tail gas, and the reaction efficiency is improved.

Description

technical field [0001] The invention relates to a chlorinated paraffin raw material pretreatment equipment. Background technique [0002] In the production process of chlorinated paraffin, due to inaccurate feeding of raw materials and insufficient reaction, tail gas containing chlorine gas and wax oil raw materials will be generated. The tail gas containing chlorine gas will be directly discharged, resulting in waste of raw materials and increasing production cost consumption. At the same time, chlorine gas is also easily mixed with air The mixture of water and vapor produces hydrogen chloride gas, which pollutes the environment; the wax oil in the tail gas will also waste raw materials, pollute the environment, and affect production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a chlorinated paraffin tail gas pretreatment equipment capable of fully separating residual raw materials from raw materi...
