Solar hot water heat supply system assisted by biomass fuel boiler as well as regulation and control method

Abstract

The invention discloses a solar hot water heat supply system assisted by a biomass fuel boiler as well as a regulation and control method. The system comprises a heat accumulating type energy-saving water heating brink bed, heat sources, room heating and domestic hot water equipment, a circulating water pipeline and a circulating water pump, wherein the circulating water pipeline and the circulating water pump are in communication with each other; the heat sources are a solar water heater and the biomass fuel boiler, the solar water heater preferentially supplies hot water to the heat accumulating type energy-saving water heating brink bed through a control switch, and the biomass fuel boiler assists in providing hot water when solar energy is insufficient; and a smoke outlet of the biomass fuel boiler is in communication with a smoke inlet of an energy-saving and emission-reducing flue wall. According to the solar hot water heat supply system assisted by the biomass fuel boiler as well as the regulation and control method, the heat accumulating type energy-saving water heating brick bed is creatively designed, the energy-saving and emission-reducing flue wall is ingeniously designed to be in communication with the smoke outlet of the biomass fuel boiler, and meanwhile continuous heat supply of a hot water system is easily and conveniently achieved in a low-cost mode. The system has the advantages of being high in heat exchange efficiency, low in pollutant emission, high in indoor air quality, high in heating quality and the like.

Description

technical field [0001] The invention relates to the technical field of solar heating systems, in particular to a biomass fuel boiler-assisted solar hot water heating system and a control method. Background technique [0002] Today, coal is the main energy source for heating in winter in rural areas in northern my country. The amount of coal burned for heating per household is about 1-2 tons per year. The consumption is huge, and the smoke emitted after combustion causes environmental pollution. At the same time, the heating methods in the northern region are mainly stove heating and boiler combustion heating. The smoldering coal in the stove can easily cause the surface of the stove to be heated unevenly. At the same time, the harmful smoke generated during the smoldering process penetrates into the room through the gaps in the stove surface, and the indoor air quality deteriorates. In addition, it is troublesome to add fuel in the boiler and stove, which will pollute the i...

Problems solved by technology

[0005] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a biomass fuel boiler-assisted solar hot water heating system and a control method to solve the problem of large coal consumption in winter heating of farm houses in northern areas and the fact that existing solar water heaters only use For domestic hot water, it is troublesome to replace the fuel when the existing bio-fuel kang is used, the indoor air quality is low, and the environmental pollution caused by the combustion of coal and bio-fuels, etc.
