Technical Field

The utility model relates to the technical field of dye processing and production, in particular to a high-efficiency reaction kettle for dye production.

Background technique

Dyes are organic compounds that can give other substances a bright and firm color. Since the pigments currently used are all artificially synthesized, they are also called synthetic dyes. Dyes and pigments are generally compounds that have their own colors and can give other substances a bright and firm color in a molecular or dispersed state. And because dyes can be directly dissolved in water and can color fibers and other materials without the use of related chemical methods, they have been widely used in the coloring process of various materials including cotton and linen.

In the dye production process, a reactor is needed to synthesize the dye. Moreover, the reaction is an exothermic reaction, which requires cooling during the reaction to ensure the normal progress of the reaction. However, the existing reactor has a poor cooling effect, which will affect the reaction results and reduce product quality and production efficiency. At the same time, after the reaction is completed, the inside of the reactor needs to be manually cleaned, which is difficult to clean and has low cleaning efficiency.
