New energy combined heat supply device

Abstract

The invention relates to the technical field of heat supply, in particular to a new energy combined heat supply device. The new energy combined heat supply device comprises a heat supply pipeline anda photovoltaic water heater; the heat supply pipeline comprises a water return pipe and a water supply pipe, the water return pipe and the water supply pipe are connected with a water inlet and a water outlet of the photovoltaic water heater respectively, the water supply pipe is further connected with an electric water heater, and the water return pipe is also connected with a circulating water pump, a decontamination pipeline and a supplementing water pipe; a heating radiator and a water mixer are further connected with the heat supply pipeline; and solar energy and the electric water heaterare comprehensively utilized so that all-weather heating can be achieved. Under normal weather conditions, the photovoltaic water heater is started to collect heat energy, and the solar energy is used for heating or preparing hot water. In cloudy days and rainy days, the electric water heater can be used as a supplement of the solar energy, and the continuity of building heating or hot water preparation can also be guaranteed; and by arranging a standby decontamination pipe in the decontamination pipeline, normal heat supply of the circulating heat supply pipeline can be guaranteed when a dirt separator of the decontamination pipe is cleaned, and influences brought to users are avoided.

Description

technical field [0001] The invention relates to the technical field of heat supply, in particular to a new energy combined heat supply device. Background technique [0002] New energy heating refers to the use of natural gas, electricity, geothermal, solar energy, industrial waste heat, clean coal, nuclear energy and other clean energy to achieve low emission and low energy consumption heating methods through high-efficiency energy utilization systems. In recent years, due to environmental pollution Increasingly serious, social resources are increasingly scarce, so new energy has attracted the attention of the market and people. [0003] Compared with traditional heating methods, new energy has the advantage of saving resources. In recent years, my country has put into use clean energy heating projects such as air energy and solar energy, which has effectively saved our country's coal storage and solved the problem of coal Storage capacity is increasingly scarce, and clean e...
