Technical Field

[0001] The invention belongs to the technical field of sodium acetate purification, and particularly relates to a sodium acetate extraction and purification method and processing equipment. Background Art

[0002] Sodium acetate, also known as sodium acetate, is an organic substance. In the laboratory, sodium acetate is often used as a reagent for acid-base neutralization reactions to adjust the pH value of the solution. In industry, it is usually used as a raw material or intermediate to participate in the synthesis of various organic compounds. In the food industry, sodium acetate can be used as a food acidifier, flavoring agent and preservative. It can adjust the pH value of food and extend the shelf life of food. In the pharmaceutical field, it can be used as a buffer and stabilizer for drugs, which helps to adjust the pH value of drugs and enhance the stability of drugs. The purification of sodium acetate is a delicate process involving multiple steps. The main purpose is to remove impurities, improve the purity and quality of the product, and make it have better performance and stability in chemical reactions, material preparation, food processing and other fields.

[0003] A method for purifying sodium thioglycolate is disclosed in the patent application number 202011014500.2. The purification method of the application provides a method including desalting and concentration in one. The solvent extraction method is used to obtain the sodium thioglycolate with high content and few salt impurities. In the process of eluting the sodium thioglycolate concentrate with 40%-42% industrial liquid alkali, energy consumption is saved compared with evaporation concentration, and the oxidation of the thiol group caused by the high-temperature evaporation process is avoided, thereby improving the quality of the finished sodium thioglycolate.

[0020] (2) When the device is in use, since the centrifugal spray body is arranged at the top of the inner side of the drying body, when the sprayed droplets have already contacted the wall of the device before reaching the surface drying, they will stick to the inner wall of the drying body.
