摘要
The extremely poor sewage quality could make the sewage heat utilization difficult. The paper introduces the content and distribution property of the sewage dirt. For the dirt properties and project experience, it proposes the two basic points of the anti-blocking technique in sewage source heat pump system: filtering surface continuous regeneration and dirt continuous reduction and the request for filtering pore size parameters. It also describes the principle of filtering surface hydraulic continuous regenerative technique and establishes its mathematical model and design method of the device. The calculation and application result indicates that filtering surface hydraulic continuous regenerative technique can guarantee the filtering effect and operation flow stable.
