Description

Wind-powered electricity generation and solar energy power generating complementation are applied in the heating device on the methane-generating pit
Technical field
The present invention relates to a kind of wind-powered electricity generation and solar energy power generating complementation and be applied in heating device on the methane-generating pit, belong to technical field of new energy application.
Background technology
Though China has found biogas very early, but apply is in the later stage twenties 20th century, Cantonese sieve state is auspicious to build up the concrete marsh-gas pond that first has actual use value, has set up " Chinese state auspicious casinghead gas head office ", builds methane-generating pit specially and produces the biogas light fixture.After the founding of New, the Premier Zhou Enlai is concerned about the construction of rural energy in person, and the 1950's, more than 600 ten thousand methane-generating pits were built up in the whole nation to the beginning of the seventies, many county governments set up " biogas office ", are responsible for providing material of construction such as cement, sandstone, support peasant household's construction methane generating pit.A large amount of constructions of methane-generating pit, promoted rural economy and agriculture production development, improved the sanitary condition in rural area.National departments concerned has been carried out large-scale base application technical study, introduces the external anaerobism research new results of digestion.Progressively perfect science build pool technology, zymotechnique and support equipment.
In March, 1986, inventor's Miao TongChun is at the invitation of China Academy of Agriculture Mechanization, former Beijing Institute of Agricultural Mechanization in the China Agricultural University of Beijing has participated in the international rural energy meeting that UNESCO holds, session, the participant to Daxing District, Beijing (former Daxing County) visited the large-sized biogas demonstration project, the useless assorted organism of the cow dung urine of large-scale diary farm, Daxing District and rural area is focused on fermentation gas in the methane-generating pit, biogas is by pipe-line transportation each peasant household to this village, the fuel that both can be used as the biogas kitchen range, cook, there is not peculiar smell during cooking, very cleaning; Also can be used for the illumination of lighting a lamp of peasant household, biogas lamp is very bright.Delegates to the meeting come into peasant household's dwelling house, hear that peasants to using the satisfied explanation and the straightforward laugh of biogas, have also heard peasant's suggestion: methane-generating pit summer aerogenesis many, winter, aerogenesis was few, aerogenesis not when cold, air feed is inhomogeneous in 1 year, and hope can solve this practical problems.
Inventor's Miao TongChun is gone on the top of Daxing District, Beijing large methane tank then along staircase, that is that an area reaches 160 square metres cement planar top, although Miao TongChun stands the direct projection of blowing hard of north wind and sunlight at the cement pit top, but hear that the peasant about the few enquirement of methane-generating pit aerogenesis in winter, did not have to think deeply the way that to deal with problems at that time.
Summary of the invention
Epoch are improving, and science is in development.Enter 21 century, the solar energy industry and the wind energy industry of China have had more and more faster development.Inventor's Miao TongChun is joined in the new energy development work of participating in, up to 2010, Miao TongChun has just been realized sun power and the wind energy that makes full use of in the outside physical environment of methane-generating pit, to contain in sunlight and strong wind in energy transformation become electric energy, introduce the heating device of methane-generating pit inside by conductor wire, suitably improve the temperature of the fermented liquid in the methane-generating pit, activation biogas bacterium, increase the biogas number of bacteria, improve digestion rate, realize that methane-generating pit increases the purpose of biogas output winter.
The solar cell 1 that solar light irradiation is installed in 2 tops of bracing frame day by day on the bracing frame base 3 produces direct current, direct current is adjusted the back, is then imported photovoltaic DC-to-AC converter 6 and convert alternating-current to by conductor wire 4 input photovoltaic controllers 5, alternating-current input is arranged on the photovoltaic register 15 in the fermented liquid in the sweathouse 17 of methane-generating pit 19, convert electric energy to heat energy, disperse heat, suitably increase the temperature of fermented liquid, promote growth and the breeding of biogas bacterium, accelerate the speed of decomposing organic matter, thereby improve the output of biogas; The blade 7 of the wind blows aerogenerator 9 of hemisphere rotates around the rotating shaft 8 of aerogenerator, drive aerogenerator 9 and produce direct current, direct current is adjusted the back, is then imported wind-powered electricity generation invertor 11 and convert alternating-current to by conductor wire 4 input wind-powered electricity generation controllers 10, behind the alternating-current input wind-powered electricity generation heating device 16, convert electric energy to heat energy, distribute heat energy, suitably increase the temperature of fermented liquid, promote growth and the breeding of biogas bacterium, accelerate the speed of decomposing organic matter, improve the output of biogas equally;
The biogas raw material enters sweathouse 17 in the methane-generating pit 19 from feed space 13 by feed-pipe 14, fermented liquid in the water pressure house 21 is pushed down the outlet of discharge nozzle 20, make the sweathouse 17 in the methane-generating pit 19 form anaerobic environment, just can make the normal output biogas of methane-producing bacteria in the biogas fermentation flora;
The biogas of output rises between gas storage 18 from the fermented liquid of sweathouse 17, biogas gathers the back and form certain pressure, and when the user used gas, biogas was by pneumatic tube 22 and storage cover 23 outputs, and supply user's biogas kitchen range burning is used; When the removable cover 12 at methane-generating pit 19 tops was removed, the confession serviceman passes in and out the maintenance methane-generating pit or the cleaning personnel pass in and out cleaning natural pond slag in the pond.
Solar cell 1 has the 1-800 piece, and the length of every solar cell 1 is 0.1 meter-1 meter, and width is 0.1 meter-0.5 meter, and the electric power of every solar cell 1 is 0.1 watt-80 watts; The kind used of solar cell 1 has: monocrystaline silicon solar cell or polysilicon solar cell or silicon-based film solar cells or compound film solar cell.
Aerogenerator 9 has the 1-80 seat, and the electric power of every aerogenerator 9 is 10 watts-2 kilowatts.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The solar radiation solar cell produces direct current, after direct current input photovoltaic controller is adjusted, then imported photovoltaic DC-to-AC converter and converts alternating-current, alternating-current input photovoltaic heating device to, convert electric energy to heat energy, distributes heat energy in fermented liquid; The blade shroud of wind blows aerogenerator rotates around the rotating shaft of aerogenerator, drive the aerogenerator running and produce direct current, after direct current input wind-powered electricity generation controller is adjusted, then import the wind-powered electricity generation invertor and convert alternating-current to, behind the alternating-current input wind-powered electricity generation heating device, also in fermented liquid, dispel the heat, obviously improve the temperature of the fermented liquid in the sweathouse in the methane-generating pit.Promote to be dispersed in growth and the breeding of the biogas bacterium in the biogas raw material, make the biogas bacterium in suitable temperature environment, accelerate the speed of decomposing organic matter, thereby improve the output of biogas.
