[0002] Sodium sulfate is an industrial solid waste produced during the brine refining process in the chlor-alkali industry. It is the common name for sodium sulfate containing water of crystallization. At the same time, Sodium sulfate is an important inorganic salt mineral. It is widely used in chemical, light industry, medicine, food and other fields. Since Sodium sulfate contains a large amount of water of crystallization, it needs to be dried and dehydrated before subsequent processing or storage.

[0003] In traditional Glauber's salt drying and dehydration devices, Glauber's salt materials are usually added in an intermittent manner, which is not only cumbersome to operate, but also difficult to achieve continuous and uniform addition of materials, thus affecting the drying effect. At the same time, traditional drying methods often rely on simple hot air convection, lacking strong shearing, blowing, floating, rotation and other effects, resulting in insufficient material drying and high energy consumption. To this end, we provide a drying and dehydration device for the production of Glauber's salt in the chlor-alkali industry to solve the above problems. Summary of the invention
