Description
Technical Field
The utility model relates to the technical field of energy sources, in particular to a solar heat collection system and a solar heat collection network.
Background
The burning of the scattered coal is one of the main factors causing pm2.5 pollution and haze in the air, and particularly, the scattered coal which is heated and burned in winter in rural areas is a direct reason for serious haze in winter in China. However, the heating problem in rural areas is still not solved effectively so far. The main transformation schemes at present are coal to gas and coal to electricity.
Because the natural gas resource reserves in China are small, the whole winter heating requirement in the north can not be met, the fuel cost is high, and the resources consumed by engineering reconstruction and the like are large. If a large amount of imported natural gas is adopted, the problem of heat supply safety is inevitably caused. Thus, "coal to gas" can only be used as a supplementary means and not as a basic heat supply guarantee.
The current application of 'coal to electricity' is limited in a small part of areas, and the main reasons are that the investment of a heat pump is huge, the heat supply cost is high, and the comfort level in a severe cold period is poor. These factors limit their popularization and application, and cannot be used as a basic heat supply guarantee at present.
Therefore, at present, the vast rural heat supply problem still does not have a perfect solution, and the coal burning is still the main solution. Under the encouragement of various clean heating policies in China, various clean heating means are provided, wherein solar heating is a very potential direction.
The heat utilization of solar energy is to convert the radiant energy of solar energy into heat energy, and the device for realizing the conversion is a solar heat collector. The solar heat collector is the most mature technology in solar heat utilization, and has the advantages of simple structure, convenience in maintenance, energy conservation, environmental friendliness and the like.
The current solar heat collectors mainly include two major types, vacuum tube heat collectors and flat plate heat collectors. The former adopts a vacuum glass tube for light transmission and heat preservation, and has the advantages of high efficiency, low temperature resistance and the like. However, the heat collector has higher manufacturing cost (initial investment is about 1000 yuan/m)2Heat supply area), not withstand voltage, not freeze proof has restricted its more extensive application. The flat plate collector is pressure-resistant, low-temperature resistant and slightly low in cost, but has poor heat collection efficiency in a severe cold period. Both of these solutions have not been widely used due to the above factors.
