[0002] The sewage source heat pump is a type of water source heat pump. As we all know, the advantages of the water source heat pump are the large heat capacity of water and the good heat transfer performance of the equipment, so the heat exchange equipment is more compact and the change in water temperature is smaller than the change in outdoor air temperature. Therefore, the operating conditions of the sewage source heat pump are more stable than those of the air source heat pump.

[0003] When sewage from existing sewage source heat pumps flows through pipes and equipment, scaling is likely to occur on the heat exchange surface, and microorganisms attach and grow to form biofilms.

During the existing cleaning, the filter device needs to be disassembled, and then the internal filter cartridge needs to be cleaned. The operation is cumbersome and affects the filtering efficiency and time. Utility Model Content
