Automatic production technology of chlorinated paraffin

Abstract

The invention relates to an automatic production technology of chlorinated paraffin. A continuous kettle type chlorinating technology production control process combining a thermal chlorination process with a photo-chlorination process is adopted, the automatic production technology of the chlorinated paraffin is that the traditional intermittent production process is changed into a continuous production process, forced circulation is changed into natural circulation, and the photo-chlorination process is that an optical fibre technology is adopted for introducing ultraviolet light for replacing an incandescent tube and a distributed automatic control production system is used for replacing manual operation. According to the technical scheme, the automatic production technology of the chlorinated paraffin has the advantages of high chlorine conversion rate, continuous production, safety, low energy consumption and automatic operation.

Description

technical field [0001] This patent relates to a chlorinated paraffin process, in particular to an automatic control process for the automatic production of chlorinated paraffin, which replaces the original artificial intermittent operation and high energy consumption chlorinated paraffin production mode. Background technique [0002] There are mainly three kinds of chlorinated paraffin production technologies in China: thermal chlorination, catalytic chlorination, and photochlorination; these three processes have their own characteristics. [0003] (1) thermal chlorination method [0004] Chlorine molecules are excited by thermal energy to dissociate into chlorine free radicals, which then react with hydrocarbon molecules to generate various chlorine derivatives. This method has mature technology and stable product quality, and most domestic chlorinated paraffin factories adopt this method. However, the device investment of this method is large, the conversion rate of chlo...

Problems solved by technology

In this method, the conversion rate of chlorine gas is high, the cost is low, the product quality is stable, and the environmental protection is easy to meet the standards. However, during the production process, the fluorescent lamp tube is in the reaction tube of the reactor or in the reactor, which is easy to catch fire and cause frequent safety accidents.

[0009] This shows, there is following shortcoming in above-mentioned existing chlorinated paraffin production technique: (1) chlorine conversion rate is low; (2) can not produce continuously; (3) electric wire aging occurs in production process and easily causes explosion; (4) chlorination The forced cycle of the process consumes a lot of energy; (5) It is impossible to realize automatic unmanned operation
