1.How to evaporate:

Vacuum heat pump evaporator uses vacuum pump to keep the system in a high vacuum state(<5000pa), so that the temperature of the material liquid boiling is reduced to between 35-40 oC, thereby increasing the heat transfer efficiency and evaporation effect.

2. How to heat exchange:

Vacuum heat pump evaporator uses heat pump technology to provide energy for evaporation. Its energy consumption is only used to drive the compressor to run, which greatly saves energy consumption and achieves more than 90% energy saving

Vacuum heat pump evaporator characteristics:

1. Plug and play, no additional steam and cooling water is required.

2. Compared with traditional evaporation technology, heat pump evaporation technology can save more than 90% in energy consumption.

3. Ultra-low temperature evaporation. The vacuum degree is above -0.095Mpa, the evaporation temperature is 35-40 oC. More suitable for heat-sensitive effluent. For corrosive effluent, the degree of corrosion of the equipment is minimized, and the life of the equipment is greatly extended compared to traditional evaporators.

4. Modular design. The structure of the equipment is more compact, the area is small, and the assembly operation is fast and convenient.

5. Fully automatic control, one-key start, automatic feed, automatic discharge, material break alarm.

6. Low failure rate, stable operation, extremely low repair and maintenance costs.

Process description

1. Effluent flow:

The effluent is sucked into the evaporation chamber under vacuum. Turn on the heat pump compressor heating and condensing cycle system to heat the effluent and condense the vapor, so that the effluent is continuously evaporated. In the process of evaporation, it is continuously feeding through vacuum, ad automatic liquid level control;

After the effluent is evaporated and concentrated, it reaches the predetermined concentration ratio, and the system automatically turns on the pneumatic discharge device to transport the concentrated effluent to the storage tank. After the concentrated effluent is drained, the system automatically restarts the feed evaporation mode to perform a new round of evaporation;

PLC automatic feeding, automatic control of liquid level, automatic discharging, material failure alarm, etc., continuous evaporation without manual operation.

2. Vapor flow:

The hot refrigerant heats the effluent, and the water is vapored. Then the vapor from effluente goes into the condenser and make heat exchange with circulative water from compressor, and then condensed into water. Finally the condensed water is discharged out of system by condensate pump
