Low Temperature Evaporator V-HP-SF-10000 - 440 L/h, 64.35 kW Power, China Suppliers and Factory
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
Step 1
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.
Step 2
Evaporation & Concentration
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 refrigerates after gasification through the expansion valve, and the vapor rises and liquefies 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 it and the defoamer is automatically added. After a cycle is completed, the concentrated liquid is discharged (the time of a cycle can be set).
Step 3
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.
Step 4
Liquid Handling
Atomized liquids to achieve maximum evaporation efficiency.

Frequently Asked Questions
What is the operating temperature range for low temperature evaporation?
The operating temperature of low temperature evaporation technology is generally maintained between 35 and 40 °C.
What kinds of wastewater can be treated with this technology?
It is designed to treat polluted wastewater, water containing oil, and viscous or crystalline fluids, including cutting fluid, cleaning, surface treatment, high salt, high concentration, and inspection wastewater.
How does the system start the preheating phase?
Once the original bucket reaches a medium level, the pump generates a vacuum, water enters automatically, and the compressor heats the wastewater in the tank to about 30°C to initiate evaporation.
What happens if bubbles occur during the evaporation process?
The system features a sensor that detects rising bubbles and automatically injects a defoamer to control them.
How is the concentrated liquid discharged?
After the cycle completes, the compression pump stops, the pneumatic valve opens, the tank is pressurized, and the concentrate is discharged into the concentration barrel.
What is the purpose of liquid atomization in the system?
The liquids are atomized to maximize the overall evaporation efficiency of the treatment process.
