Self-cleaning heat transfer enhanced solar sewage source heat pump system

Abstract

Provided is a self-cleaning heat transfer enhanced solar sewage source heat pump system. Filtration is carried out on dirt impurities through a mechanical bar screen, a hair filter and other equipment, a control valve b, a control valve c, a control valve d and a control valve e are arranged in four sewage pipes connected to a sewage heat exchanger respectively, and back washing is carried out on a sewage pipeline through the switching of the opening and closing of the control valves. The problems that the dirt impurities block the pipeline, hair blocks heat-exchange equipment, the heat-exchange equipment is large in size due to dirt, the performance of the heat-exchange equipment is reduced and the heat-exchange equipment breaks down due to dirt water in the process that the sewage is used as cold and heat sources are solved thoroughly. Solar equipment is mounted on the water inlet of a water source heat pump to improve water temperature of inlet water, the problem that normal starting cannot be carried out due to the fact that the temperature of the inlet water is too low in winter, the heat exchange performance of the system is improved greatly, the safety, reliability and stability of the system are guaranteed, the self-cleaning heat transfer enhanced solar sewage source heat pump system can be applied to the field of carrying out cooling and heat supplying by using the sewage or surface water as low order cold and heat sources and using the heat pump technology, or be applied to cooling industrial equipment, and the self-cleaning heat transfer enhanced solar sewage source heat pump system is efficient and environmentally friendly.

Description

technical field [0001] The invention belongs to a sewage heat exchange system, and relates to a self-cleaning and enhanced heat exchange solar sewage source heat pump system. 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 order to solve the a...

Problems solved by technology

[0006] In order to overcome the shortcomings of 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, and it provides a self-cleaning and heat-exchanging solar sewage source heat pump system that can filter dirt of any size and combine clean and pollution-free solar technology to increase the temperature of the incoming water.
