Description
Technical field
The utility model relates to a kind of methane-generating pit, especially can prevent the incrustive methane-generating pit of raw material in the pond automatically.
Background technology
In recent years, as one in the new countryside construction important support project, the biogas engineering construction has obtained vigorously supporting and promoting of country.Yet, because the existing methane pool structure is perfect inadequately, expose some problems to be solved that still have in the use, wherein main is exactly the raw material crust.
If it is many that present methane-generating pit in use adds excrement, it is few to add water, do not note diligent discharging and stirring again, cause in the sweathouse moisture few, fermentation concentration is big, can produce the accumulation lot of organic acids, makes the upper strata crust of fermentation raw material, become the outstanding problem that current rural area hydraulic type biomass pool exists, have a strong impact on the normal use of peasant household.Incrustive formation, the biogas that causes in the pond producing are gathered and are obstructed, and useful volume and gas dome reduce, and raw material availability reduces, and gas production rate reduces, and crust when serious, tend to make a methane-generating pit in perfectly good condition, have become " sick pond " or " useless pond ".Can therefore, solve the incrustive problem of methane-generating pit, be one of the important factor that promote of puzzlement biogas engineering.Someone proposes to adopt the way of " stopping the pond " to solve the incrustive problem of methane-generating pit, stops using 5~7 days every year; But adopt " stopping the pond " way to have brought very big inconvenience for people's life; Also the someone has proposed employing " hand mixing ", promptly takes out the slag device every pulling in several days, makes the sweathouse feed liquid up and down, thereby, prevent the methane-generating pit crust, but this needs people's routine maintenance, see it is very simple stirring, also to include daily life stroke in, year after year so, as if become also very complicated, if routine maintenance is bad, also might crust, same, there is very big safe handling hidden danger.
The utility model content
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned background technology, and a kind of improvement of methane-generating pit is provided, and this methane-generating pit should have and prevents the incrustive function of raw material automatically, and can use continuously, need not increase and safeguard energy, safe and convenient to use.
The technical scheme that the utility model provides is: anti-automatically crust methane-generating pit, comprise the fermentation vat of imbedding underground tubular, the top of fermentation vat is shaped on outlet and adds top seal, also is provided with a biogas pipe that feeds the pond internal cavity on the fermentation vat Chi Ding and is used to draw biogas; Two sides that fermentation vat is relative are shaped on opening for feed and discharge port respectively, and opening for feed and discharge port are communicated with charging pond and material-output tank by pipeline respectively; It is characterized in that also being provided with in the fermentation vat anti-caking housing apparatus that is flooded by liquid in the pond, this device is thin-walled, upright tubular construction, the bottom of device uncovered and with keep certain spacing at the bottom of the pond, the top of device has an overflow port; This device is fixed on opening for feed and leads directly on one side and with opening for feed, so that the biogas raw material of input at first pours in the anti-caking housing apparatus.
The pillar stiffener bracing reinforcement is also used in the bottom of anti-caking housing apparatus.
Principle of work of the present utility model is: the biogas raw material enters the anti-caking housing apparatus by opening for feed from ground charging pond, and the part material that can float (scum silica frost) just concentrates in the anti-caking housing apparatus, and on the top of the anti-caking housing apparatus inwall that floats to; All the other most raw materials just flow in the fermentation vat from the bottom of anti-caking housing apparatus, efficiently ferment; Because the flowability of liquid is higher than the flowability of solid material far away,, and constantly pass through the overflow port outflow on anti-caking housing apparatus top so along with the continuous adding of raw material, liquid constantly impacts the interior come-up raw material of anti-caking housing apparatus; The shock vibration effect of liquid has destroyed the crust condition of biogas raw material; Constantly flowing of liquid increased the kinetic energy of fluid molecule.Like this, constantly charging is constantly floated, and liquid constantly flows out, and constantly impacts the come-up raw material in the anti-caking housing apparatus then again, and whole process has been formed a circulation continuously, thereby plays well anti-crust effect.
The beneficial effects of the utility model are: owing to set up the anti-caking housing apparatus, can prevent the methane-generating pit crust effectively, thereby improve the fermentation efficiency of methane-generating pit, thereby realize the high yield gas of methane-generating pit; And it is do not need to increase energy and safeguard, also avoided frequent changing, feed intake, and safe in utilization to people's the trouble of bringing.In addition, the utility model reduced investment, fermentation rate height, construction simply only need to increase an automatic anti-caking housing apparatus and get final product on the basis of common methane-generating pit; Even the methane-generating pit that has built up, also can be again on the basis of original methane-generating pit suitable improvement get final product, do not need other removal, reduced extra investment, obtain the consistent of people and approve, therefore, excellent popularization value is arranged.
