Solar heat supply device for villages and small towns

Abstract

The invention relates to a solar heat supply device for villages and small towns. The device comprises a solar heat supply device and a water heating furnace used as an auxiliary heat source, wherein the water heating furnace body comprises a burner cap, an adjustable burner cap, a by-pass flue, a heat absorbing filter, an ash bucket and a water tank thereof; the furnace body is arranged in the center of the upper part of the water tank of the device; a part of 2/3 height of the water tank is provided with the ash bucket below the furnace body; and the solar heat supply device is in the structure that a photoelectric pump is arranged on a solar water return pipeline, the water tank can be internally provided with a heat exchange coil, and water heated by a solar heat collector directly enters the water tank or heats cold water in the lower part of the water tank through the heat exchange coil. By adopting the solar heat supple device, the consumption of conventional fuels can be reduced, and the indoor human environment of the villages can be improved, the purposes of energy saving and emission reduction are achieved and the indoor air quality is improved, the sustainable development of energy resources can be realized, and the human environment quality of the villages and the small towns is remarkably improved.

Description

technical field [0001] The invention relates to the field of village heating and utilization of domestic hot water, in particular to a solar heating device for villages and towns. Background technique [0002] Traditionally, my country’s rural areas use fire pits and soil heating or coal stoves for heating in winter. Firewood and coal are used as fuel. The indoor thermal environment is difficult to guarantee, and accidents caused by indoor pollution such as low fuel combustion efficiency and gas poisoning Happens frequently. [0003] The technology and economy in villages and towns are relatively backward, and the economic affordability is poor, and the supply of conventional energy such as electricity is often not effectively guaranteed. At present, solar heating in villages and towns is mainly based on passive solar house heating. Active solar heating using hot water as a medium is still in the exploratory and demonstration stage due to cost, equipment, technology and othe...

Problems solved by technology

[0002] Traditionally, my country’s rural areas use fire pits and soil heating or coal stoves for heating in winter. The fuel is firewood, coal, etc. It is difficult to ensure the indoor thermal environment, and accidents caused by indoor pollution such as low fuel combustion efficiency and gas poisoning Happens frequently

[0003] The technology and economy in villages and towns are relatively backward, and the economic affordability is poor, and the supply of conventional energy such as electricity is often not effectively guaranteed

At present, solar heating in villages and towns is mainly based on passive solar house heating. Active solar heating using hot water as a medium is still in the exploration and demonstration stage due to cost, equipment, technology and other factors.
