Dredging type tubular heat exchanging device for sewage or surface water

Abstract

The invention discloses a dredging type tubular heat exchanging device for sewage or surface water and belongs to the technical field of energy. The dredging type tubular heat exchanging device aims at solving the problem that the plate type structure of the existing sewage heat exchanging device is insufficient in loading capacity, severe in water leakage accident, large in steel consumption of a sleeve structure and the like and connection blocking can be caused by suspended solids at an orifice. A multilayer heat exchanging tube is arranged in a casing, two ends of the multilayer heat exchanging tube is fixedly connected with a left tube plate and a right tube plate, the left tube plate, the right tube plate and a left end socket and a right end socket of sewage or surface water define a sewage or surface water left transition cavity and a sewage or surface water right transition cavity, a left clean water channel and a right clean water channel are arranged in the casing, and the sewage or surface water left transition cavity is communicated with the orifice of the heat exchanging tube at the corresponding layer; and the sewage or surface water left transition cavity is divided into two sewage or surface water left transition cavity units through a second vertical partition plate, the top end of the sewage or surface water right transition cavity is provided with a sewage or surface water outlet or inlet, and a sewage or surface water outlet or inlet is arranged at the bottom end of the sewage or surface water right transition cavity. The dredging type tubular heat exchanging device for sewage or surface water is used for blocking-free and efficient heat exchanging between sewage or surface water and clean water during cold energy extracting in the sewage or surface water.

Description

technical field [0001] The invention relates to a heat exchange device for sewage or surface water and clean water when utilizing cold heat in sewage or surface water, and belongs to the field of energy technology. 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 probl...
