Abstract

The invention belongs to the technical field of energy resources and relates to a forcible dredging type tubular heat exchange device for sewage or surface water. The forcible dredging type tubular heat exchange device for the sewage or surface water aims to solve the problems that an existing wide-flow-passage plate type structure is insufficient in pressure bearing capability and severe in water leakage accidents and results in retention of suspended matters and impurities, a tubular structure orifice is prone to blockage and the like. The device comprises a flow passage separation device, header dredging devices, heat exchange tubes, a shell, two tube plates, two headers, two seal heads, baffle plates, diaphragm plates, diaphragm plate holes, a sewage or surface water inlet, a sewage or surface water outlet, a heat exchange media inlet, a heat exchange media outlet and the like. The sewage or surface water flows into the device from the inlet and then flows backwards sequentially by means of blocking of the header dredging devices after being subjected to flow passage separation of the flow passage separation device, and performs heat exchange with heat exchange media outside the tubes during flowing, and after entering the device from the inlet, the heat exchange media baffle and flow in the shell by means of blocking of the diaphragm plates and the baffle plates and performs heat exchange with the sewage or surface water in the tubes during flowing. The forcible dredging type tubular heat exchange device for the sewage or surface water is used for heat exchange of the sewage or surface water with the heat exchange media.

Description

technical field [0001] The invention relates to a heat exchange device for heat exchange between sewage or surface water containing impurities and suspended matter and a heat exchange medium, and belongs to the technical field of energy. Background technique [0002] Using heat pump technology to extract cold heat from low-grade renewable clean energy for building heating and air conditioning is one of the effective ways to save energy and reduce emissions in buildings, and its energy saving rate can reach more than 45%. These low-level renewable clean cold and heat sources include: the atmosphere, soil, groundwater, surface water, urban sewage, etc. When using these cold and hot energy sources, on the one hand, it needs to be utilized according to local conditions, and on the other hand, it is necessary to effectively solve some common and key technologies question. Regarding sewage and surface water cooling heat sources, the key problems to be solved are the clogging of i...
