Technical characteristics of three effect continuous evaporation crystallizer 1, the traditional three effect manual operation is very cumbersome and difficult, our company produces three effect continuous crystallizer through PLC control, operation more stable, operation simpler, more efficient. 2, steam enters the evaporator as a heat source for the first performance for materials in the heating effect; a separation of indoor materials through evaporation of two steam into two effect evaporator as the material of the second effects in heat heating; two effect separation chamber material to produce two steam after evaporation, enter three as of third effect evaporator material in the heat source for heating. A condensate water enters the preheater as the heating source of the preheater, and the whole system makes full use of the wet and latent heat to save the consumption of the raw steam and reduce the running cost. 3, combining the advantages of enhanced boiling heat transfer and anti fouling performance of boiling evaporation and forced circulation evaporation, forming a complementary enrichment way. The utility model can realize the enhanced heat transfer, and can prevent the fouling of the heating surface of the heating tube in the process of boiling evaporation. A forced circulation device is arranged in the third through the discharge effect in the heating system, the heating pipe in the material flow rate reaches more than 2.0m/s, to achieve the purpose of heat transfer enhancement, so that the heat transfer efficiency is greatly improved, at the same time by maintaining high-speed flow of liquid in the bundle, but also to prevent the crystallization of the material in the heating pipe wall attached to the maximum, and then prevent fouling. The device is widely used in boiling evaporation crystallization process of bittern, Glauber's salt, potassium sulfate, sodium fluoride, caustic soda, sodium sulfite, manganese sulfate, sodium chloride, barium chloride, calcium chloride, alumina, ammonium sulfate, ammonium chloride, sodium nitrate, sodium sulfate, zinc sulfate solution, Magnesium Sulfate.
