Technical process video


The evaporated mother liquor can be reduced by about 70%, the moisture content of the residue is 10%~20%.

The low-temperature vacuum distillation tank is designed with a stirring scraper device, the evaporation mother liquor stays on the evaporation surface without coking or scaling

Concentrate or crystallization residue is discharged by mechanical scraping, automatic discharge, no clogging

Evaporate under low temperature (below 60 degrees) and vacuum (above -95kPa) conditions, and the content of organic matter and salt in the condensed water is low, which is easy for subsequent biochemical or physical and chemical standard treatment

Batch feeding, fully automatic operation, unattended, easy maintenance

Service process

Service process

Low temperature heat pump evaporator series

Soliges LT-I is a heat pump-based vacuum evaporator that is electrically operated.

Clean water production between 0.2T-50T/day.

Vacuum is maintained around -96Kpar, the evaporation temperature is about 37 ℃.

The energy is electricity and compressed air.

Evaporation process

The evaporation temperature is set at 35-40°C. The compressor compresses the refrigerant to generate heat. While the water evaporates rapidly, the refrigerant absorbs the heat to cool through the expansion valve. The waste water is reheated by compressing and heating through the compressor. If there are bubbles rising during the evaporation process, after the sensor detects, the defoamer is automatically added to defoam, and after one cycle is completed, the concentrated liquid starts to be discharged (the time of one cycle can be set).

Concentrate discharge

After one evaporation cycle is completed, the compression pump stops working, the pneumatic valve of the concentrate pipeline is opened, the evaporation tank is pressurized, and the concentrated hydraulic pressure is poured into the concentration barrel.
