Sewage Anti-Blocking Machine Principle and Double-Stage Pump Technology

Abstract:

The sewage should be filtered to prevent the blockage of the heat exchanger before using. And the anti-blocking machine is the key device to prevent blocking in sewage source heat pump system. The paper introduces the development of the anti-blocking machine: intermittent backwashing, flat continuous backing, cylindrical with external baffle continuous backwashing, double-stage continuous backwashing without external baffle. Also, it describes the principle of the anti-blocking machine, the key technologies and the necessity of choosing double-stage pump in sewage source heat pump system with anti-blocking machine. The paper concludes the technical characteristics, the advantages and disadvantages of the double-stage sewage source heat pump system and introduces the selecting principle of the double-stage pump. The paper clarifies some misunderstanding about anti-blocking machine and double-stage pump.
