Background: Sodium sulfate is an important chemical raw material, but its production process generates a large amount of saline wastewater, and traditional evaporation methods have high energy consumption.
Solution: Adopt MVR evaporation crystallization technology to treat sodium sulfate wastewater. After preheating, the wastewater enters the MVR evaporator for evaporation. Generated by evaporation; After being compressed by the compressor, the secondary steam is used again as heating steam, achieving the recycling of energy. Finally, sodium sulfate precipitates in the form of crystals, and the mother liquor is returned to the system for recycling.
Effect: This process greatly reduces the steam energy consumption in the production process of sodium sulfate, improves production efficiency, and reduces production costs. At the same time, the purity and quality of sodium sulfate crystals are also guaranteed.
