Description

Containerized Low-Temperature Heat Pump Evaporator

Designed with standardized, modular, and intelligent skid-mounted concepts, the containerized low-temperature heat pump evaporator system offers high flexibility and ease of transportation. The system is delivered as a fully assembled unit, enabling rapid installation and commissioning while meeting customized project requirements.

It is widely applied across industries such as food processing, chemicals, metallurgy, pharmaceuticals, and environmental protection.

The system is available in two configurations: Concentration type and Crystallization type. 

• The concentration type is suitable for applications such as food and pharmaceutical processing, emulsion concentration, organic wastewater treatment, and brine concentration. 

• The crystallization type is designed for high-salinity wastewater, enabling concentration and crystallization, and is particularly suitable for handling complex wastewater streams.

Low-Temperature Heat Pump Crystallization Evaporator

Working Principle

• Feeding

Wastewater is introduced into the evaporator under vacuum conditions.

• Heating

The heat pump system operates through vapor compression to generate high-temperature refrigerant. The refrigerant transfers heat to the feed through the heat exchange surface, gradually increasing the temperature of the material while the refrigerant is cooled.

• Agitation

A motor-driven scraper continuously cleans the heat transfer surface, preventing fouling and enhancing heat transfer efficiency.

• Evaporation

Under high vacuum, the boiling point of the feed material decreases, allowing evaporation occurs at approximately 38°C.

• Condensation

Secondary vapor is condensed into distilled water in the condenser by the cold side of the heat pump, while latent heat released from the vapor is recovered and reused by the heat pump.

• Discharge

As concentration increases, crystallization occurs. Once the target condition is reached, the system discharges the concentrated slurry or crystalline solids.
