Water taking and direct heat exchange system of sewage source heat pump

Abstract

The invention discloses a water taking and direct heat exchange system of a sewage source heat pump. A water diversion tank and a water taking tank are respectively arranged at two sides of a road; a municipal sewage well of a sewage main canal is connected to the water diversion tank via a drainage pipe and a primary mechanical grating; the drainage pipe takes water from the middle of the municipal sewage well so as to guarantee that muddy sand impurities at the bottom of the municipal sewage well directly flow to the downstream along the sewage main canal; sewage taken out from the middle part enters a primary mechanical bar screen via the drainage pipe to be filtered; filtered sewage enters the water diversion tank; the filtered impurities ascend along with the primary mechanical bar screen and fall off into a sewage drainage pipe connected with a sewage drainage pump at the other side, and further are exhausted into the downstream of the municipal sewage well; sewage entering the water diversion tank flows into the water taking tank at the other side of the road via oblique free flow pipelines arranged below the sewage main canal and the road. The water taking and direct heat exchange system of the sewage source heat pump is very suitable for application types of sewage source heat pumps at two sides of the sewage main canal and separation roads of heating buildings.

Description

technical field [0001] The invention belongs to a sewage source heat pump system, in particular to a sewage source heat pump water intake system. Background technique [0002] The use of cold and heat sources of sewage can alleviate the current situation of energy shortage. It has good energy-saving effects, environmental protection benefits and economic benefits. It will save increasingly scarce fresh water resources, open up new fields for energy utilization, and provide comprehensive and comprehensive utilization of water resources. A new train of thought. The main reason why sewage cold and heat sources are not widely used and promoted is that their water quality cannot meet the water quality standards required in the current water circulation system. In actual operation projects, these sewage often block the water pumps and heat exchangers, resulting in system performance. Significantly down, can't even run. [0003] In order to solve the above problems, the filter su...
