Description
Technical field
Patent of the present invention belongs to environment protection and renewable energy source domain, and particularly the biogas about harmless treatments such as cold district livestock and poultry farms in scale fecaluria and slaughterhouse sewage is produced system.
Background technology
Along with the raising of expanding economy and living standards of the people, China's livestock and poultry breeding industry develop rapidly, but this has also caused the pollution problem of livestock and poultry fecalurias serious day by day, has become the principal pollutant of rural environment pollution of area source.Simultaneously, China will face the energy scarcity problem for a long time, demand developing new forms of energy such as biomass energy urgently.The application of biogas technology solves the good method of this two aspects problem just.Biogas technology is through the development of many decades, the comparative maturity and obtained widespread use in China south, and the average factor of created gase of livestock and poultry farm biogas engineering that current China is moving reaches 0.4m
3/ (m
3D).As a kind of anaerobe technology, aerogenesis apparatus just can not normally move when its temperature of reaction is lower than 10 ℃.Be subjected to the influence of aspects such as geography and climate, area is northeastward protected in the winter of generally using, two seasons of spring at present, heating technology is not ideal enough, causes biogas technology to be difficult to promote.
Summary of the invention
Technical problem to be solved by this invention is: solve the north cold area winter emphatically, two seasons of spring produce the biogas difficulty; heat, heat preservation technology is unreasonable; be difficult to realize annual biogas continuous production; existing biogas engineering factor of created gase is low, and livestock and poultry farms in scale fecaluria and slaughterhouse sewage can not get phenomenons such as processing in time.Provide a kind of and be suitable for the solution livestock and poultry cultivation fecaluria of north cold area and the mass-producing biogas of slaughterhouse sewage is produced system.
The present invention is design like this:
The biogas that a kind of cold district livestock and poultry farms in scale fecaluria is handled is produced system, mainly constitute by marsh-gas fermentation tank 7, marsh-gas fermentation tank 7 two ends are provided with opening for feed 1 and discharge port 5, tank body top is provided with draws hole 4, it is characterized in that: the outer setting of described marsh-gas fermentation tank has duplicature heliogreenhouse 2, the marsh-gas fermentation tank inner bottom is provided with heating tube 8, the biogas fermentation pot bottom is provided with bioreactor 10, the tank body outside surface design of marsh-gas fermentation tank has tank body thermal insulation layer 3, described marsh-gas fermentation tank is by duplicature heliogreenhouse 2, tank body thermal insulation layer 3, bioreactor 10 is incubated, and described marsh-gas fermentation tank is by duplicature heliogreenhouse 2, heating tube 8, bioreactor 10 heats; Described bioreactor 10 adds saccharifying enzyme and cuts up with a hay cutter broken straw and stir sealed storage; Described marsh-gas fermentation tank adopts all steel matter structure, all scribbles sanitas inside and outside the tank body; The opening for feed 1 of described marsh-gas fermentation tank is connected with pretreatment pool 11, and described discharge port 5 is connected with detritus pool 6, and the described hole 4 of drawing connects the biogas storage jar; Described marsh-gas fermentation tank 7 tank base are provided with fermentor tank supporting seat 9, are distributed in the bioreactor, support tank body.
The invention has the beneficial effects as follows: adopt the biogas of the cold district livestock and poultry farms in scale fecaluria processing of above-mentioned design to produce system; the bottom of marsh-gas fermentation tank 7 is furnished with heating tube 8; when the fermentation raw material temperature in the marsh-gas fermentation tank 7 descends; can start heating unit; improve the temperature of heating tube 8, thereby improve the fermentation raw material temperature in the marsh-gas fermentation tank 7.The surface of marsh-gas fermentation tank 7 is surrounded by tank body thermal insulation layer 3, and tank body thermal insulation layer 3 can reduce marsh-gas fermentation tank 7 and dispel the heat in duplicature heliogreenhouse 2, guarantees the effect of fermentation raw material temperature of reaction in the marsh-gas fermentation tank 7.Duplicature heliogreenhouse 2 can effectively absorb sun shortwave in the duplicature heliogreenhouse, and terrestrial surface radiation is blocked in the greenhouse by plastics film, so the temperature in the greenhouse constantly raises.By taking above measure, can guarantee the temperature of fermentation raw material in the marsh-gas fermentation tank 7 well, thereby solve the problem that north cold area is produced the biogas difficulty winter, realize all can effectively producing biogas throughout the year, harmless treatment livestock and poultry farm fecaluria and slaughterhouse sewage.
Environmental benefit:
By promoting advanced practical biogas technology, the livestock and poultry fecaluria be can eliminate and water, underground water, air environmental pollution and microbial contamination shown over the ground, improve the rural environment quality, environmental benefit is huge.
Economic benefit:
Calculate with 10,000 pig farms of livestock on hand:
Produce about 14600 tons of fecaluria per year.Build biogas facility total reaction volume 1000m
3, about 1,600,000 yuan of whole project total cost.
Can produce biogas 300000m the whole year
3Can make cooking fuel for 1000 family left and right sides resident.1.25 degree if every cubic metre of biogas of generating can generate electricity, 0.4 yuan of calculating of every degree electricity, ten thousand yuan of benefit=1.25 * 0.4 * 300000 yuan=$15.
The natural pond slag is made a senior organic fertilizer, produces 12 tons of fertilizers every day, and You Jifei $100 per ton is first to be calculated; Year is reclaimed ten thousand yuan/year of benefit=12 * 100 * 250 yuan/year=$30.
Developing the commercialization utilization of natural pond liquid.Natural pond liquid has huge business potential, can be used for seed soaking, foliage fertilizer after natural pond liquid is handled, breeds fish and soilless culture etc. alternative chemical fertilizer, feed.
