[0002] The concentration and distillation device for chemical production is one of the important equipment in the chemical industry. Its working principle is to utilize the difference in boiling points of different substances to vaporize the volatile components in the mixture by heating, and then cool and condense them in the condenser, thereby achieving separation and concentration of the mixture. This device is widely used in the chemical, pharmaceutical, food and other industries to purify and concentrate various liquid mixtures and improve the purity and concentration of the products.

[0003] The heater surface of the existing concentration and distillation device used in chemical production is prone to impurities. During the chemical production process, due to the complexity of the raw materials and long-term operation, impurities will gradually accumulate on the heater surface, which will not only reduce the heat transfer efficiency of the heater and increase energy consumption, but may also affect the distillation effect and product quality. The presence of impurities may also cause local overheating of the heater, increase the risk of equipment damage, and shorten the service life of the equipment.

[0004] Therefore, in order to address the problem that impurities are easily attached to the surface of the heater of the existing concentration distillation device for chemical production, a concentration distillation device for chemical production can be designed, in which a stirring device of the heating device is combined, and while stirring, the liquid impacts its surface to clean the attached impurities.
