Description

Technical Field

[0001] The utility model belongs to the technical field of sodium sulphate production and processing, in particular to a device for electrically drying sodium sulphate. Background Art

[0002] Sodium sulfate is a salt formed by the combination of sulfate and sodium ions. Sodium sulfate is soluble in water, and its solution is mostly neutral. It is soluble in glycerol but not soluble in ethanol. It is an inorganic compound. The high-purity, fine-grained anhydrous substance is called glauber's salt. Glauber's salt is white, odorless, bitter crystals or powders. It is hygroscopic and has a colorless, transparent, large crystal or granular small crystal appearance. Sodium sulfate is easily exposed to air and absorbs water to form sodium sulfate decahydrate, also known as Glauber's salt, which is alkaline. It is mainly used to manufacture water glass, glass, porcelain glaze, pulp, refrigeration mixture, detergent, desiccant, dye diluent, analytical chemical reagents, pharmaceuticals, feed, etc. In organic synthesis laboratories, sodium sulfate is the most commonly used post-processing desiccant. The upstream raw materials include sulfuric acid, caustic soda, etc. Among them, glauber's salt needs to be dried during the production process. In order to improve the treatment effect and efficiency, it is necessary to propose a device that uses electric drying of glauber's salt.
