Abstract

The utility model relates to a combined heating system of rural biogas bioenergy and solar energy, which belongs to the technical field of heating and heating. The system is composed of solar heat collection system, heating system, biogas generation promotion system and auxiliary heating system. This system mainly solves the problems of insufficient gas production in winter biogas digesters and insufficient supply of solar hot water in rural areas. Solar hot water first enters the floor heating coil to heat the room, and then flows through the disc-shaped heat exchange coil of the biogas digester to heat the biogas digester, thereby increasing the gas production of the biogas digester. Under the action, it enters the wall-type biogas water heater, and after heating, it flows into the energy storage water tank to form a hot water circulation system combined with biogas bioenergy and solar energy for heating. This system makes full use of biogas bioenergy and solar energy, improves energy utilization efficiency and saves operating costs.

technical field

The utility model relates to a combined heating system of rural biogas bioenergy and solar energy, which belongs to the technical field of heating and heating.

Background technique

At present, my country's building heating generally adopts a centralized heating method, which requires a large investment and is difficult to realize in rural areas, and cannot meet the heating needs of rural areas in winter. In rural areas, coal and other fossil fuels are generally used for heating, which produces a large amount of harmful carbon monoxide, carbon dioxide, etc. Gas, not only pollutes the environment, but also has low energy efficiency. At present, energy conservation and emission reduction and improvement of energy utilization efficiency are a basic national policy of our country. Therefore, using solar energy and wall-type biogas water heaters to heat homes is a way of energy conservation and emission reduction and improvement of energy utilization efficiency. It can be used reasonably and maximized. Combined heating with solar energy and biogas not only enables the hot water to be used twice, but also makes the most effective and reasonable use of solar energy and biogas bioenergy.

detailed description

Figure 1 is a schematic diagram of the connection of a rural biogas bioenergy and solar combined heating system

See Figure 1: A combined heating system of rural biogas bioenergy and solar energy, which consists of a solar heat collection system, a heating system, a biogas growth promotion system, and an auxiliary heating system.

Its working principle is: utilize solar heat collecting plate 1 to absorb solar energy, and convert it into hot water thermal energy. On the one hand, the hot water flows through the floor heating coil 10 for room heating; on the other hand, the heating return water flows through the biogas pit 13 and enters the disc-shaped heat exchange coil 14 to heat the biogas pit and increase the biogas output. When the temperature measured by the temperature detector 8 exceeded 70° C., the controller 6 would increase the resistance and automatically slow down the water flow rate. The hot water flowing through the biogas tank enters the wall biogas water heater under the action of the circulating water pump. The wall biogas water heater burns the biogas to heat the return water, and then flows into the energy storage tank. The amount of water lost by evaporation in the system forms a hot water circulation system combined with biogas bioenergy and solar energy for heating.
