Description

Methane packaged technical equipment for cold area
Technical field
A kind of methane packaged technical equipment for cold area belongs to biogas practical technique field.
Technical background
Biogas is a kind of flammable mixed gas that organism under anaerobic generates through the fermentative action of microorganism.Its major ingredient is methane and carbonic acid gas, generally methane (CH 4) account for about 60% carbonic acid gas (CO 2) account for about 40%.Development biogas cause both can have been produced biogas as the energy, can handle organic waste again with the protection environment, and the natural pond slag behind biogas fermentation, natural pond liquid are the high-quality fertilizer material.The biogas construction is closely connected life of farmers, production and is in the same place with the ecological agriculture, promoting peasant programme, and structure of agricultural production adjustment and agricultural play significant role with the aspects such as Sustainable development of rural economy.
The generation of biogas is an organism at secluding air and keep under the conditions such as certain temperature, humidity, potential of hydrogen, decomposes and produces through the fermentation of multiple microorganism (general designation biogas bacterium).The temperature range of biogas fermentation is bigger, generally can both produce biogas under 8-60 ℃ of condition.Temperature is actually the influence to the fermentation raw material fermenting speed to the influence of biogas fermentation, and when temperature raise, the vital movement of biogas bacterium was vigorous, and the fermenting speed of fermentation raw material is fast, and the methane tank gas production amount is big, and fermentation period is just short; When leavening temperature was low, the fermenting speed of fermentation raw material was slow, and the methane tank gas production amount is few, and fermentation period is longer; Biogas can't produce when the sweathouse temperature was lower than 8 ℃ in the pond.
Rural households' formula methane-generating pit under the subzero 7-8 of temperature ℃ the situation, increases the insulation measure on methane-generating pit top in the winter time at present, and as ox, horsehit, mulch film or faggot cover, and still can produce biogas.Further technology mode is that methane-generating pit, livestock and poultry house, lavatory, arviculture chamber are arranged in the heliogreenhouse, forms the system of a sealing.Heliogreenhouse is printing opacity and the diffusing performance of resistance of utilizing plastics film; and supporting composite heat insulating wall body structure; with conversion of solar energy is heat energy; protect simultaneously and stop scattering and disappearing of heat and moisture content; reach the purpose that heats, is incubated, the winter indoor and outdoor temperature difference can be reached about 30 ℃, in the subzero 20 ℃ of conditions of external temperature; temperature can remain on about 10 ℃ 8-10m in the heliogreenhouse 3The biogas that produces of methane-generating pit can do two meal meals for 4 mouthfuls family and use.But the fund input of this daylight temperature methane-generating pit is bigger, and general peasant household can not build, and methane-generating pit neither a separate component simultaneously, must wherein one or more join together just can take effect with livestock and poultry house, lavatory, arviculture chamber.And reach subzero at outside air temperature and can not produce biogas below 20 ℃ the time.
Also have a kind of solar biogas tank arrangement, CN200967821Y is autocratic, and document has been announced this technology, and superiority is to install solar energy collector, normal temperature fermentation is changed into helped hot fermentation, and it is feasible continuing to keep aerogenesis under subzero temperature more than 20 ℃.But because this installs in solar energy collector conduit without any heat-conducting medium, cold district faint solar heat in winter can not be given full play of, there is not heat-storing device to match yet, there are not heating assist measures such as other fuel, electric power, lose sunlight and just lost thermal source, cause simple very thin glass steel shell tens hours severe cold of subzero 20-30 ℃ of resisting that rely at this device night, normal gas producing is impossible.Simultaneously, the charging discharging can not be worked continuously, but takes disposable mode of reloading fully greatly, and also be worthless this winter at cold district.So it is also inapplicable that the annual four seasons of high latitude cold district are produced biogas.
Purpose of the present invention just provides and a kind ofly reaches subzero below 20 ℃ in external temperature, still can normally produce biogas under the condition to the north of 38 ℃ of the longitude and latitude north latitude, can independently use simple installation, processing ease, cheap, be fit to the biogas technology equipment that cold district uses, equipment has a style of one's own, and is multiple functional, the user can directly install and use, and moves aerogenesis throughout the year.
Superiority of the present invention is:
1, it is reliable to heat system.Adopted the sun power medium to heat, solar energy heat-storage heats, and absorption film heats, and biogas process furnace medium heats quadruple and heats measure, can take the different modes that heats according to the variation of external temperature, to satisfy microbial life active needs in the housing.Particularly guarantee the subzero sweathouse normal gas producing below 20 ℃ time of external temperature in winter.
2, heat-insulation system is reliable.Warming plate, insulating foam, thermal insulation coatings, insulation sealing coat quadruple insulation measure have been adopted, to prevent that temperature leaks in the housing.
3, can be according to attenuation degree charging, discharging.Not needing stops the supple of gas or steam reloads greatly.To keep the stability and the continuity of aerogenesis.
4, because functions of the equipments are complete, standard is unified, and it is uneven because of building technology to have overcome traditional methane tank, be through debugging the complicated process that can use repeatedly.Settle at one go, installing the by specification operation just can aerogenesis.
Methane packaged technical equipment for cold area, for cold district winter subzero below 20 ℃ to the north of the north latitude 38 under the condition biogas production technical guarantee is provided.The north methane of making over uses the situation in spare time half a year to improve half a year.Can be at northwest loess plateau, the northwest Wind-sandy Area, vast cold districts such as Qinghai-Tibet Platean, Northeast plain mountain area, Inner Mongolia Autonomous Region practice.
Summary of the invention
The invention provides a kind of methane packaged technical equipment for cold area, reach subzero below 20 ℃ to the north of the north latitude 38 under the condition, realize that methane-generating pit normally moves aerogenesis in external temperature.
The objective of the invention is to be achieved through the following technical solutions:
