Considering the characteristics and complexity of various solutions in different factories, our company will provide specific technical solutions for the composition and content of solutions with crystal precipitation provided by users for their reference and selection!

Equipment Composition
This equipment consists of a heater, forced circulation pump, evaporator separator, condenser, various material pumps, condensate pump, vacuum pump, operating platform, electrical instrument control cabinet, and internal pipeline valves..

Working principle

The material liquid is heated by the steam outside the heat exchange tube in the heater, resulting in an increase in temperature. Under the action of the circulation pump, the material rises into the evaporation separator. Due to the decrease in static pressure of the material, it evaporates, producing secondary steam that overflows from the material liquid. The material is concentrated and becomes supersaturated, causing crystal growth. The material that is released from supersaturation enters the forced circulation pump and, under the action of the circulation pump, enters the heat exchanger. The material continues to evaporate and crystallize in a cyclic manner, achieving separation between substances and purifying chemical substances and obtaining chemical products.

main features
According to the characteristics of the material and the size of the evaporation capacity, it can be designed as a single effect or multi effect evaporation unit.

2. Adopting a uniquely designed crystallizer, it can meet the zero process requirements of continuous feeding and discharging. The forced circulation of the evaporator forms a good fit, and its internal structure enables effective and rapid separation of crystals and clear liquid.

3. The entire process involves evaporation under vacuum conditions, with relatively low temperature and fast evaporation rate. The evaporation energy consumption is low, and the evaporation concentration is high, making the viscous liquid easy to flow and evaporate without scaling.
