Scheme design: 41t/h MVR evaporation crystallization system
1. The raw material is the mother liquor of ternary lithium precursor, which is deammoniated + deweight +MVR evaporator evaporation and crystallization
2. Evaporator capacity: 1000t/d
3. Evaporation capacity of evaporator: 41t/h, including deammonia, weight removal, water washing system
4. Evaporator material: 304 stainless steel
Product Features
MVR is the abbreviation of mechanical vapor recompression technology, which uses the secondary steam and energy generated by the evaporation system itself to compress low-grade steam into a high-grade steam heat source through the mechanical work of the steam compressor. This cycle provides heat energy to the evaporation system, reducing the demand for external energy, thereby improving thermal efficiency, reducing energy consumption, reducing pollution, and achieving the purpose of energy saving.
Project results
1. Realized resource recycling:
Sodium sulfate industrial dry salt grade, in line with GB/T5462-2015 index requirements. The water produced by the deammonia process meets the requirements of the technical agreement.
2. The operating cost of a ton of water is about 35 yuan, and the operating cost is controlled reasonably to realize the conversion of waste resources into treasure.
3. The project is a model project in the lithium battery recycling industry, and the process technology is currently at the leading level at home and abroad.
