Description
Technical field
The utility model relates to solar light-heat power-generation and the complementary methane-generating pit that improves factor of created gase of photovoltaic generation, belongs to technical field of new energy application.
Background technology
The scale that China promotes methane-generating pit is that the whole world is maximum, and state plan to 2010 year will develop ten thousand mouthfuls in methane-generating pit to 2600.These methane-generating pits mainly are distributed on the south the Changjiang river, because the inner natural pond liquid fermentation of methane-generating pit needs suitable leavening temperature, could produce more biogas.Under the medium temperature condition about 35 ℃, biogas fermentation can produce best economic benefit.The temperature environment of methane-generating pit outside is quite big to the influence of the course of fermentation in the liquid of natural pond, methane-generating pit inside.Chinese vast northern area, vast central and west regions; Particularly on the Qinghai-Tibet Platean; Because the daily mean temperature that has many days in a year is lower than the needed temperature of the normal fermentation of biogas; Therefore limited methane-generating pit in many geographic development, many methane-generating pits that built up can not be fully used.
The staple of biogas is methane CH
4, methane is reproducible geseous fuel, colorless and odorless and can burn after the air mixed.Biogas is clean energy; Can be peasant household illumination, heating are provided, biogas may be made in can be as the automobile-used biogas of automotive fuel, can vehicle with automobile-used biogas; The country that Northern Europe has is greatly developing the biogas automobile, and purpose is to reduce from the world market upper inlet oil.
On October 7th, 2011, the market value of the egg that China produces went up 15.7% than on October 7th, 2010, and the price of the egg in Guizhou Province in October reaches 0.85 yuan of Renminbi, and it is low in economic efficiency that peasant household's dispersion is raised chickens and laid eggs.Have only and build 100,000 poulty houses, 1,000,000 poulty houses that the scale of going up is raised laying hen; And utilize chicken manure in methane-generating pit, to concentrate generation biogas to be used for marsh gas power generation in a large number; Inside and outside the poulty house, supply power; Take in the chicken raising cost that reduces the scale prodn egg with the electricity charge of marsh gas power generation, could reduce and keep the stable of Egg price for a long time.
At present; Since many methane-generating pits lack effectively heat, insulation, temperature adjustment auxiliary facility; Not only many methane-generating pits of northern area have the time about half a year in 1 year and do not produce biogas because temperature is low, even the factor of created gase of many methane-generating pits of southern area is also not high enough.
