Description
Technical field
The present invention relates to a kind of method that rural energy utilizes, the method for say so more specifically a kind of methane-generating pit and booth coupling.
Background technology
Uncontrolled along with the sharp increase of the development of world industrial economy, population and human being's production mode of life; world climate faces more and more serious problem; CO2 emissions is increasing; earth's ozone layer is just suffering unprecedented crisis; the calamitous climate change in the whole world occurs repeatedly, and serious harm is to existent environment of people and healthy and safe.Chinese as a developing country, on total amount, the CO of present China
2Quantity discharged has occupied the second in the world; Expect 2025, the CO of China
2Quantity discharged surpasses the U.S. probably, occupies the first in the world.Therefore China demand urgently need be to the CO that is discharged
2Catch research, to alleviate the atmospheric pollution pressure of China.At present, the capture mode of carbonic acid gas mainly contains three kinds: capture (Post-combustion) after capturing (Pre-combustion), oxygen-enriched combusting (Oxy-fuel combustion) and burning before the burning.
Development of marsh gas in rural area is the rich people's that benefit the nation a strategic engineering.Since country project verification in 2003, country successively dropped into national debt fund and greatly developed the production and use of marsh gas for 10,500,000,000 yuan recent years, and project relates to 6417 counties time.The Central Committee of the Communist Party of China, State Council pointed out in " some suggestions that the new socialist countryside of going ahead in a down-to-earth manner about the develop actively modern agriculture is built " in 2007, accelerate development the rural area clean energy, continue to increase the rural methane facilities development input, central authorities in 2008 drop into national debt fund and reach 25.2 hundred million yuan, the investment cumulative year after year.Show that according to the statistics made by the departments concerned by the end of the year 2007, national household biogas has reached more than 2 600 ten thousand families, the popularity rate in all suitable peasant households reaches 18.3%, increases progressively 17.5% every year, has also built up place surplus plant's biogas engineering 2.6 ten thousand simultaneously.
There are problems in the current rural methane facilities development; the peasant only is confined on " cook, light a lamp " such everyday use the understanding majority of construction methane generating pit effect; heightened awareness is not to the vital role of biogas construction to aspects such as ecological protection and improvement, resource circulation utilizations, at CO
2All there is bigger shortcoming isothermal chamber gas purging and natural resources reasonable disposition aspect; In winter, when external temperature was lower than zero degree, underground methane-generating pit was in and produces half a lifetime or stop production status, has seriously limited the gas producing efficiency of methane-generating pit.At present, aspect the methane-generating pit insulation, mainly contain following measure: on methane-generating pit, build simple and easy temperature canopy before the open country methane-generating pit is gone into the winter, in methane-generating pit is covered; Cover the methane-generating pit insulation with stalk, plastics film, carry out in time that charging and discharging mouth, hydraulic pressure pond etc. directly contact with the external world, the insulation of heat dissipation capacity larger part.
Guan Yingui, Jiang Gongjian, Wu such as wash down at the integrated ring shaped anaerobic biogas generating pit of people's invention, adopt the composite integrated design, have reduced the seepage probability, and facility compact, floor space is little, production efficiency is high; Has intensity height, corrosion-resistant, advantages such as thermal conductivity is low, high insulating effect, long service life.At present, the utilization of rural area booth and methane-generating pit is all universal, but does not take certain measure that the two is carried out organically combination.For the research of existing methane-generating pit, only be confined to the material, constructional feature of methane-generating pit itself etc., unsatisfactory for the adaptation effect of external environment (as low temperature).In addition, above-mentioned CO
2Trapping technique exists popularity rate not high, is subjected to problems such as region and restraint of trade.Therefore, for methane-generating pit insulation and CO
2The capture problem is needed the solution that finds more cheap easy row badly.
Summary of the invention
In order to solve the deficiency of resource distribution in the existing production and use of marsh gas utilization, reach the low-carbon (LC) requirement simultaneously, the purpose of this invention is to provide the method for a kind of methane-generating pit-booth coupling, near the residential area, set up booth, the inner methane-generating pit of installing is collected the CO that residential area biogas burning generates
2, utilize gas release device, with CO
2Be discharged in the booth, utilize plant CO
2Absorb, can energy efficient, realize carbon emission reduction, improve CO
2Assimilated efficiency improves crop yield simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
The method of a kind of methane-generating pit-booth coupling, its step is as follows:
(a) set up booth near the grange district, methane-generating pit is installed in booth inside, the residential area utilizes the biogas of methane-generating pit generation as the energy, and be incubated methane-generating pit with booth winter;
