Heating Type Integrated Heat Exchange Unit

Classification: Sewage Waste Heat Recovery System
Product Details

Working Principle

  The heating type integrated heat exchange unit adopts stepped heat transfer and heat pump integration technology. Heat pump technology is an energy utilization method to efficiently recover medium and high grade waste heat by consuming a small amount of electric energy, which can extract more than 75% of the waste heat energy in the process wastewater. In addition, the cooling capacity discharged by the unit can also be used for the cooling process of the production workshop and the cooling process, and meet the process requirements that the temperature of the sewage mixed into the sewage treatment plant not higher than 38℃.

  The waste water pump delivers the treated wastewater to the pre - and post-effect heat recovery heat exchanger, transfers most of the heat to the new water, and then releases the heat to the heat pump through the intermediate medium to cool the heat twice, and the final drainage temperature can be reduced to 20-25℃. At the same time, the released heat is absorbed by the refrigerant, then by the heat pump, the refrigerant transfers the heat to the new water through the intermediate medium, and the final temperature of the new water can reach up to 60-75℃.

  The unit has a refrigeration function. The cooling output can be achieved by switching the function keys. When necessary, it can be directly connected to the cooling system for heat exchange, to cool down the cooling needed process or to improve the working environment of the workshop. The wastewater discharge temperature will increase, while hot water production is not affected.
