A kind of new bio nido methane-generating pit
Technical field
The utility model relates to a kind of new bio nido methane-generating pit, specifically be a kind ofly to utilize biological nest material as microbe carrier, thereby improve the methane-generating pit fermentation efficiency, improve a kind of new bio nido methane-generating pit of biogas output, belong to the biogas generating device technical field.
Background technology
In recent years, the application of methane-generating pit in day-light greenhouse obtains people's attention and development gradually, in day-light greenhouse behind the construction of marsh gas tank, the biogas that produces is used for lighting a lamp or cooks by the cooking stove burning and heats up water, in save energy, can also heat and be incubated for booth, effectively solve short, the insufficient problem of photosynthesis of sunshine time in winter, and promote to promote good quality and high output by the greenhouse crops healthy growth.At biogas lamp or methane cooker incendiary simultaneously,, can solve in the canopy problems such as the fertile deficiency of gas, reduce humidity in the canopy, promote the metabolism of plant to help the growth of plant and the accumulation of carbohydrate for vegetables in the booth or fruit provide carbon-dioxide gasfertilizer.Make foliage fertilizer, drip irrigation fertilizer after natural pond liquid in the methane-generating pit filters, can prevent Powdery Mildew, gray mold, the generation of prevention aphid, mite class; Natural pond slag in the methane-generating pit not only can substitute chemical fertilizer, and can also improve the soil, and is high-quality fertilizer.By the comprehensive utilization in " three natural ponds ", plant the gourd, fruit and vegetable that comes out and meet the non-polluted farm product standard.It is estimated: 1 800m 2Sun light green house, build 8 cubic metres of methane-generating pits, 400～500 cubic metres of year aerogenesis, can obtain the heat (biogas calorific value 5000～5500 kilocalorie/cubic meters) of 2,750,000 kilocalories, when temperature of shed is minimum, light biogas lamp, biogas stove morning, temperature of shed is risen 2 ℃～3 ℃ for booth provides the heat of 1.1 ten thousand kilocalories, prevent freeze injury, and, can save coal more than 2 tons every year for life brings convenience, economize on the use of funds about 600 yuan.Can provide 6 tons of natural pond slags, 4 tons of natural pond liquid in 1 year simultaneously.Natural pond per ton slag is equivalent to 80 kilograms of carbon ammoniums, and natural pond per ton liquid is equivalent to 20 kilograms of carbon ammoniums, can save 560 kilograms of fertilizer every year.Natural pond fertilizer is the high-quality fertilizer material, has both reduced pollution, and the soil fertility of having fostered and apply fertilizer makes vegetables early go public again, can increase economic efficiency more than 20%.Can also improve gas concentration lwevel in addition.The indoor carbon dioxide content sometimes of canopy less than 0.1%, have a strong impact on vegetable growth, can produce 0.975 cubic metre of carbonic acid gas after 1 cubic metre of biogas burning, by lighting biogas lamp, the biogas stove can make the gas concentration lwevel in the booth reach 0.1%～0.13%, satisfy the needs of vegetable growth, produce carbon-dioxide gasfertilizer with the use additive method and compare, can economize on the use of funds more than 200 yuan.
Construction of marsh gas tank in daylight vegetables or fruit booth, when saving the energy, the root of vegetables or fruit, stem, leaf the like waste etc. when promoting peasant's volume increase, increasing income, can also solve the problem of interior vegetables of booth or fruit waste pollution as the part material of methane-generating pit.
Yet, because methane-generating pit all is a underground type ortho-water pressure type domestic methane tank in the booth at present, gas producing efficiency is on the low side, cause the biogas that produces not enough, and pursuit simply increases the methane-generating pit volume, has increased investment again virtually, and the peasant is not easy to accept, the development that this has limited methane-generating pit in the booth has influenced the enthusiasm of booth user construction methane generating pit.Therefore, the factor of created gase of methane-generating pit in vegetables or the fruit booth has become one of important factor of restriction booth vegetable fruit production area's biogas development.
Publication number is the Chinese patent of CN201305595, discloses a kind of novel film-type marsh gas tank, by add biological bacteria bed dividing plate in methane-generating pit methane-generating pit is divided into three districts, and biological bacteria bed dividing plate is connected with the bottom with the methane-generating pit top up and down, is staggered.But this patent design more complicated, peasant household is not easy to accept.
