Description
We manufacture vacuum heat pump crystallizers for industrial wastewater. We have extensive experience designing, manufacturing, and installing wastewater crystallizers. Our vacuum heat pump crystallizer has its own characteristics. These characteristics vary with the type of wastewater treatment industry.
Heat pump is a device that transfers the heat energy from low temperature heat source to high temperature heat source. It is more energy saving, fast and safe than using electric heater to make heat.
Industrial Pain point
Most factories usually treat high salt industrial wastewater through evaporation crystallizer. The existing evaporation crystallizer usually uses traditional steam or electric heating evaporation technology, which consumes high energy, and must be equipped with steam boiler, cold water tower and other equipment, covering a large area.
Advantages
1.The vacuum degree is about -95KPa, and the evaporation temperature is about 35-40ºC;
2. Intelligent automatic control system, simple operation, convenient and efficient;
3. It occupies a small area and is almost unattended;
4. High concentration ratio of wastewater and high purity of evaporated water;
5. Using air energy heating technology, the technology is stable, safe, energy-saving and environmentally friendly;
6. Up to the sewage discharge regulations,almost 0 maintenance.
Application
Concentration of machining wastewater
Concentration of pickling phosphating solution
Landfill leachate treatment
Concentration of high ammonia nitrogen wastewater
Spraying wastewater treatment
Coating wastewater treatment
Treatment of Wire Electroplating Washing Wastewater
Treatment of polyamide production wastewater
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 ºC) 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.
