Heat Pump Scraper Drying Crystallization System

Evaporative crystallization equipment system is a common equipment in the evaporation industry and also commonly used equipment in industrial production, chemical wastewater treatment process.

Evaporation crystallizer equipment is mainly used for the evaporative crystallization of crystal precipitation solution, widely used in chemical industry, metal mining smelting, power plant wet desulfurization waste liquid treatment, also commonly used in sodium chloride, phenylpropylferric acid, sodium sulfate, ammonium chloride, glycine and evaporative crystallization of barium chloride, zinc sulfate, calcium chloride, ammonium sulfate and sodium hydroxide.

Greenlan VESALT heat pump low temperature drying crystallization system breaks the conventional principle of evaporative crystallization process, using low temperature vacuum evaporation process, is a horizontal evaporator, through a specially designed pump to make the evaporation chamber vacuum pressure up to ≈33 mbar, so that water will boil at 30°C ~ 40°C low temperature. It enables concentrated liquid to be processed into a dry powder solid. This is actually to minimize the disposal of hazardous waste liquids.

As a pioneer in the field of heat pump distillation crystallization, Weihai Greenlan has nearly 30 years of rich experience, dozens of patents and more than 5000 global installation cases. Its unique design and impeccable quality of products are well-known. The main characteristics are as follows:

1. Made of AISI 316L stainless steel, fully detachable.

2. Heat pump low temperature vacuum distillation design, using R134a refrigerants.

3. Only heat source is electricity. No steam is needed for heating or as an auxiliary heat source.

4. Wastewater intake, distilled water, concentrated liquid effluent are fully automated operation.

5. Completely closed without exhaust emissions.

6. The control system uses Siemens PLC and control panel.

7. Modular design, compact structure, small footprint, fast and convenient assembly and operation.

   
   

OPEX analysis：

Greenlan VESALT heat pump scraper drying crystallization system operation consumption is only power. Under normal and smooth operation, distillation of 1m3 water consumption of 130-160 degrees of electricity, the operating costs are as following:

Based on the 24-hour operation, if the average electricity cost per day is 0.7 RMB/KWH, and the cost of distilling 1m3 of water is about 84 to 105 RMB.
