Efficient sewage heat exchange system capable of carrying out on-line cleaning and automatic decontamination

Abstract

Provided is an efficient sewage heat exchange system capable of carrying out on-line cleaning and automatic decontamination. Filtration is carried out on dirt and impurities through devices such as a grit chamber, a water taking pool and a hair filter, filtered sewage enters a sewage heat exchanger along with solid particles separated through a solid-liquid separator to participate in heat exchange, meanwhile, a control valve b, a control valve c, a control valve d and a control valve e are arranged on four sewage pipes respectively, the sewage pipes are connected with the sewage heat exchanger, and back washing is carried out on the sewage pipes through switching between opening and closing of the control valves. The problems that in the process of using the sewage as a cold and heat source, the dirt and the impurities block pipelines, hair blocks a heat exchange device, the size of the heat exchange device is large due to the dirt, and performance reduction and faults of the heat exchange device are caused by turbid water are thoroughly solved; heat exchange performance of the efficient sewage heat exchange system is greatly improved, it is ensured that the efficient sewage heat exchange system is safe, reliable and stable, the efficient sewage heat exchange system can be used for using the sewage or surface water as a low-level cold and heat source to carry out cooling and heating through a heat pump technology, or used for cooling industrial devices, and high efficiency and environmental friendliness are achieved.

Description

technical field [0001] The invention belongs to a sewage heat exchange system, and relates to an efficient sewage heat exchange system capable of online cleaning and automatic decontamination. 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 way of thinking. 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 or...
