Technical introduction

      The heat pump vacuum evaporator, operating at 35-40 ° C, can significantly reduce the COD of distillate and a small amount of discharged 

concentrate. The technology is low maintenance cost, automated.

      The vacuum evaporator can effectively and simply treat wastewater without using reagents. They are very effective even when traditional 

technologies are not feasible. With the vacuum heat pump evaporator, the wastewater is converted into two streams: one is highly concentrated, 

and the other is high-quality water (up to the discharge standard). The evaporator works under vacuum conditions to reduce the boiling temperature 

of wastewater and reduce energy consumption.

Principle of the vacuum heat pump evaporator

      The operation of the heat pump vacuum evaporator is based on making the stock solution reach its boiling point, which is about 35-40 °C under 

vacuum conditions.

1. Freon (heat medium) is compressed by the compressor, the temperature rises, and the heat is transferred to the waste water in the evaporation tank.

2. After heat transfer, the raw liquid in the evaporation chamber reaches the boiling point (about 35-40 ℃) under negative pressure.

3. Freon after heat exchange of evaporator is cooled through expansion valve.

4. The expanded low temperature Freon makes the temperature of cooling circulating water lower.

5. The low temperature cooling circulating water makes the vapor formed in the evaporation tank condense rapidly to ensure that the evaporation 

tank is in a negative pressure state.

Therefore, the system doesn't need any other heating or cooling sources.

This means that the process is very beneficial from an economic and management perspective.
