Low Temperature Evaporation Technology
Low temperature evaporation refers to the evaporation process with an operating temperature generally between 35 and 40 ° C. The technology mainly deals with a variety of polluted wastewater, water containing oil products and viscous or crystalline fluids, especially from cutting fluid wastewater, cleaning wastewater, surface treatment wastewater, high salt wastewater, high concentration wastewater, inspection wastewater or other production process water.
Basic Principle of Low Temperature Evaporation Technology
Preheating
This step is automatic. After the original bucket reaches the medium level, the pump runs to produce vacuum, the evaporator automatically enters water, and the compressor runs to generate heat to heat the wastewater in the evaporation tank. In the vacuum state, the wastewater temperature rises to about 30℃, and the wastewater begins to evaporate, and the preheating is completed.
Evaporation and Concentration Process
The evaporation temperature is set at 35-40℃, the compressor compresses the refrigerant to generate heat, and the water evaporates rapidly at the same time, the refrigerant absorbs heat and refrigeration after gasification through the expansion valve, and the vapor rises and liquefied into the cold liquid into the water storage tank. The refrigerant absorbs heat, and then compresses and heats the waste water. If bubbles rise during the evaporation process, the sensor detects that the defoamer is automatically added to the defoamer, and after a cycle is completed, the concentrated liquid is discharged (the time of a cycle can be set).
Concentrate Discharge
After the completion of an evaporation cycle, the compression pump stops working, the concentrate pipeline pneumatic valve is opened, the evaporation tank is pressurized, and the concentration hydraulic pressure is put into the concentration barrel.

Frequently Asked Questions
What is the typical operating temperature for low temperature evaporation?
The operating temperature for low temperature evaporation technology is generally maintained between 35 and 40 °C.
What kinds of industrial fluids can this technology treat?
It treats a variety of polluted wastewater, oil-containing water, and viscous or crystalline fluids, including cutting fluid wastewater, cleaning wastewater, surface treatment wastewater, high salt wastewater, high concentration wastewater, and inspection wastewater.
How does the preheating step work in the evaporator?
Preheating is automatic. When the original bucket reaches a medium level, the pump creates a vacuum, water enters the evaporator, and the compressor heats the wastewater to about 30℃ in the vacuum state to start evaporation.
What happens if bubbles rise during the evaporation and concentration process?
If bubbles are detected by the sensor during evaporation, the system automatically adds a defoamer to control the foam and maintain process safety.
How is the concentrated liquid discharged after processing?
Once the cycle completes, the compression pump stops, the concentrate pipeline pneumatic valve opens, the evaporation tank is pressurized, and the concentrated liquid is discharged into the concentration barrel.
