Good performance of cryogenic cooling crystallization technology and equipment Sep 28, 2018

Cryogenic cooling crystallization is a cooling crystallization technique that relies on lowering the temperature of the material to cause supersaturation of the material and ultimately crystallization of the material. This technique is more suitable for treating systems where solubility is significantly reduced with temperature.

 

The cooled crystallizer for cryogenic cooling crystallization is cooled by an external tube heat exchanger, and the heat of the clarified mother liquid is removed by the cooling liquid, and then sent to the bottom of the crystallizer by a circulation pump to form an outer circulation passage. . The equipment can achieve continuous operation, high production intensity and high efficiency.

 

The low-temperature cooling crystallizer has good mixing effect, uniform supersaturation distribution, and is difficult to crystallize. The crystal product has good quality, coarse particles and uniform particle size distribution. It can produce large-grain crystal products with particle size of 500-2000μm, which can fully satisfy the user's crystallization of products. Different particle size distribution requirements, can be applied to barium chloride, ferrous sulfate, potassium chloride, magnesium sulfate, potassium sulfate, sodium carbonate, sodium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, potassium dihydrogen phosphate, phosphoric acid Crystallization of products such as ammonium dihydrogen phosphate, urea phosphate, and sodium hypophosphite.
