Multistage jacketed chlorinated paraffin reaction tower

Abstract

The invention relates to a multistage jacketed chlorinated reaction tower, and belongs to the field of paraffin processing equipment. The multistage jacketed chlorinated paraffin reaction tower includes a cylindrical tower body and end covers arranged at both ends of the tower body; the tower body is provided with at least two ring jackets and, each jacket is provided with at least a circulating liquid outlet and at least one circulating liquid inlet. According to the multistage jacketed chlorinated paraffin reaction tower, the multistage jackets are externally arranged on the reaction tower, the cooling effectiveness of the multistage jackets can be controlled when in use, so that materials in each part of the reaction tower can be fully reacted, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a multi-stage jacketed chlorinated paraffin reaction tower, which belongs to the field of paraffin wax processing equipment. Background technique [0002] Chlorinated paraffin can be widely used as a plasticizer and because of its good flame resistance, it can also be used for flame retardancy of plastics and rubber, waterproof and fireproof additives for fabrics, additives for coatings and inks, and pressure-resistant lubricating oils. additive. [0003] The preparation methods of chlorinated paraffin currently include thermal chlorination method, catalytic method and photocatalytic method. In the above three methods, the reaction heat generated by the reaction needs to be taken out during the production process. At present, the more commonly used method is to use a pump to force the external circulation of the reactants in the reactor, and reinject the reactants cooled outside the reaction tower.

AI Technical Summary

Problems solved by technology

In the above three methods, the reaction heat generated by the reaction needs to be taken out during the production process. At present, the more commonly used method is to use a pump to force the external circulation of the reactants in the reactor, and reinject the reactants cooled outside the reaction tower. In the reaction tower, although this method is effective, the materials injected back into the reaction tower are not uniform, and repeated cycles waste energy

In addition, due to the gradual progress of the reaction, the viscosity of the reaction material in the reaction tower will increase from top to bottom, resulting in a decrease in the reaction rate of the material in the lower part.
