Abstract

The invention relates to a tubular channel-type heat exchange method for sewage or surface water, and belongs to the field of energy technology. The method aims at solving the problems that the heat exchange manner of an existing plate-type structure has an insufficient pressure bearing capacity, the water leakage accident is terrible, the tubular structure consumes a large amount of steel, the pipe mouth of the tubular structure is often blocked, and suspended solids and impurities retain in the channel of a plate-type broad runner structure. The method provided by the invention is that a plurality of side-by-side runners are arranged in a channel-type case; part of the sewage or surface water flows to a pipe mouth 22, and the other part of the sewage or surface flows in an opposite direction, which means that the flow directions of the two parts of sewage or surface water form an angle of 180 DEG C, so that suspended solids cannot form a blockage in an inlet; a plurality of channelizing baffle plates are arranged on tube plates at both ends of a heat exchange pipe, and the outlet of one exchange pipe only corresponds to the inlet of the next heat exchange pipe, so that the inlet of an internal heat exchange pipe cannot be blocked. When the method provided by the invention is used for extracting the heat of sewage or surface water, the sewage or surface water as well as media cannot be blocked, the heat exchange efficiency is high, and the method is simple in theory and reliable.

Description

technical field [0001] The invention relates to a method for exchanging heat with a medium by using cold heat in sewage or surface water and belongs to the technical field of energy. Background technique [0002] Utilizing the cold and heat in low-grade renewable clean energy such as sewage or surface water to provide heating and air conditioning for buildings, generally using heat pump technology, 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 cloggin...
