Tubular heat exchanging device with dredging structure for sewage or surface water

Abstract

The invention provides a tubular heat exchanging device with a dredging structure for sewage or surface water and belongs to the technical field of energy. The invention is to solve problems that in the traditional wide runner plate type structure, serious accidents are caused, suspended solids and impurities are detained in a runner, and the pipe opening of a tubular structure is blocked. According to the invention, the device comprises a runner separating device, a heat exchanging tube, a shell, two tube plates, two collecting boxes, two sealing heads, a baffle plate, a transverse partition plate, a transverse partition plate hole, a dredging plate and so on, wherein the runner separating device comprises a runner separating shell, a runner separating plate, a separating runner, a runner separating inner opening, a runner separating inlet and so on; the sewage or surface water enters from an inlet and flows backwards in sequence under the blocking of the dredging partition plate after being separated by the runner separating device; and in the flowing process, heat is changed between the sewage or surface water and a heat exchanging medium outside the tube. The tubular heat exchanging device with the dredging structure for the sewage or surface water, provided by the invention, has the advantages as follows: through runner separation and dredging, blockage and detaining caused by the suspended solids and the impurities are guaranteed. The tubular heat exchanging device with the dredging structure for the sewage or surface water, provided by the invention, is used for achieving no blockage and efficient heat exchanging of the sewage or surface water and the medium and has the advantages of simple and reliable principle.

Description

technical field [0001] The invention relates to a heat exchange device for exchanging heat between sewage or surface water containing impurities 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 impurities and the i...
