Description

Technical Field

[0001] The utility model belongs to the technical field of chlorinated paraffin production, in particular to a chlorinated paraffin chlorination reactor with a quantitative function. Background Art

[0002] A chlorinated paraffin chlorination reactor is a device used to carry out chlorination reactions. This reactor usually includes a reactor in which paraffin and chlorine react under high temperature and high pressure conditions to produce chlorinated paraffins with different degrees of chlorination. The degree of chlorination refers to the number of chlorine atoms on each carbon atom, which can be adjusted by controlling the reaction conditions.

[0003] The chlorinated paraffin chlorination reactor in the prior art needs to stir the paraffin and chlorine to accelerate the reaction rate between the two. Most of them use mechanical stirring. Simple mechanical stirring easily increases the temperature in the reactor and causes friction between the materials and the inner cavity of the reactor, which affects the reaction of paraffin and chlorine and reduces the service life of the reactor. At the same time, most of the existing reactors cannot quantify the input of chlorine and paraffin, resulting in a loss of control of the ratio of reactants, affecting the reaction efficiency, and causing excess of some raw materials, wasting costs.

[0004] Therefore, we provide a chlorinated paraffin chlorination reactor with quantitative function to solve the above problems. Utility Model Content
