Solar sewage-source heat pump system capable of carrying out on-line cleaning and automatic decontamination

Abstract

Provided is a solar sewage-source heat pump 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, 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 a 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 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; due to the fact that a solar device is installed on a water inlet of a water source heat pump, the temperature of inlet water is increased, the problem that normal starting cannot be carried out due to the fact that the temperature of the inlet water is excessively low in winter is solved, heat exchange performance of the solar sewage-source heat pump system is greatly improved, it is ensured that the solar sewage-source heat pump system is safe, reliable and stable, the solar sewage-source heat pump 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 a solar sewage source heat pump system capable of online cleaning and automatic decontamination. Background technique [0002] The use of sewage as a cold and heat source can alleviate the current energy shortage situation, has good energy-saving effects, environmental protection benefits and economic benefits, saves increasingly scarce fresh water resources, opens up new areas for energy utilization, and provides comprehensive and comprehensive utilization of water resources. A new train of thought. 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 order to solve...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the deficiencies in the above-mentioned prior art, the present invention effectively solves the problems of blockage of heat exchange tubes, growth of dirt, low heat exchange efficiency, machine failures, etc. caused by too much dirt and different sizes, as well as the low temperature of incoming water in winter. It is difficult to turn on the problem, providing a solar sewage source heat pump system that can filter any size of dirt, combined with clean and pollution-free solar technology to increase the temperature of the incoming water, online cleaning and automatic decontamination
