Description

Technical Field

[0001] The utility model relates to the technical field of flocculant production, in particular to a polymerization reaction device for flocculant production. Background Art

[0002] Flocculants are chemical substances used in water treatment and wastewater treatment. When producing flocculants, a polymerization reaction device is required. Polymerization reaction is a chemical reaction used to prepare chemicals such as polymer materials. In the polymerization reaction, the reactants self-assemble through the formation of chemical bonds to eventually form a polymer compound.

[0003] Most of the current polymerization reaction devices are composed of a kettle box, a stirring device, a jacket, etc. The inventors found in the actual operation process that since the polymerization reaction is an exothermic reaction, if the reaction system (usually including a mixture of reactants, products, catalysts and solvents) is overheated, the reaction will intensify, resulting in the escape of product gas and solvent or the burning and explosion of the reaction system. Therefore, we proposed a polymerization reaction device for flocculant production. Utility Model Content
