AI Technical Summary
Traditional low-temperature evaporation crystallization devices for high-salt wastewater use a single stirring method, resulting in uneven mixing of wastewater and uneven concentration in some areas, which affects the purity of the crystallized salt. Furthermore, the stirring device is prone to scaling, has low heat transfer efficiency, and high energy consumption.
The main and auxiliary stirring rods rotate synchronously in different directions. Combined with the scraper inside the auxiliary stirring rod to clean the tank wall, it achieves enhanced mixing and real-time cleaning of wastewater. It is equipped with a filter device to remove suspended solids and prevent impurities from entering.
This improved the purity of the crystallized salt and the operating efficiency of the equipment, reduced energy consumption and maintenance costs, and ensured the continuous and efficient operation of the equipment.
