Description

Compound inside and outside floating top stirring-type methane-generating pit
Affiliated technical field
The utility model relates to a kind of methane-generating pit, relates to a kind of compound inside and outside floating top stirring-type methane-generating pit specifically.
Background technology
Biogas be organic substance in anaerobic environment, under the condition of certain temperature, humidity, potential of hydrogen, by the microbial fermentation effect, a kind of inflammable gas of generation.Biogas contains multiple gases, and main component is methane (CH 4).Along with the popularization of China's biogas science and technology development and rural area household biogas, the quantity of methane-generating pit also increases gradually.The pool-type structure of the separation storage air-float hood methane-generating pit that is adopting at present is methane-generating pit and floating cover water seal tank two portions (see reprinted by Inner Mongol rural ecological energy source station " methane-generating pit technological standard compilation " book the 34th page), methane-generating pit is approximately kettle shape, generally build in underground, floating cover and water seal tank and methane-generating pit are separated, set up separately, generally build on the ground, both connect with air delivering pipeline.This band is compared with existing other types methane-generating pit by the methane-generating pit of floating cover, and several big advantages are arranged, and the one, air pressure is constant, helps the raising of the efficiency of combustion of methane cooker, lamp; The 2nd, the voltage stabilizing fermentation, fermented liquid is no longer gone here and there back and forth at water pressure house, has improved factor of created gase; The 3rd, methane-generating pit can be filled material, has improved tankage; The 4th, improved resistance to air loss.But also there are following several big shortcomings simultaneously: one,, build the pond cost so improved owing to need to set up floating cover and water seal tank separately; Two, floor space is bigger; Three is the same with existing other type pond, and earth volume is bigger when building the pond, generally needs the earthwork of excavation 10-12 cubic meter; Four, fail well to solve the stirring problem; Five, acquire a certain degree of difficulty equally during big discharging.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of compound inside and outside floating top stirring-type methane-generating pit, and this methane-generating pit floor space is little, and the pond type is less, can effectively reduce and build the pond cost, and the factor of created gase height is easy to discharging, and safety performance is good, and is simple in structure, and cost is lower.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of compound inside and outside floating top stirring-type methane-generating pit, the biomass pool body of charging liquid in comprising, this biomass pool body bottom connects feed-pipe and discharge nozzle respectively, and its structural feature is: floating top is installed on said biomass pool body top, and airway is installed on this Fu Ding top.When the intravital feed liquid of methane-generating pit produces biogas, biogas rises floating top internal gas pressure is increased, emersion feed liquid gradually under the floating effect that withstands on biogas air pressure, biogas exists in the floating top, because the sealing function on the water seal effect of feed liquid and floating top, biogas can be kept in the floating top or by airway and flow to the outside, floating top rises to certain altitude, floating top can descend gradually during with gas, rises gradually after dropping to certain position again, works so repeatedly.
Said Fu Ding stretches at the center body bottom, pond mounting center sleeve pipe, uniform agitating vane on this center sleeve.Agitating vane is installed on the center sleeve, rotates floating top and can stir feed liquid.
Said floating top is the floating top of two-layer compound of the sealing that is combined into by internal floating roof cover and outer floating overhead guard, said internal floating roof cover and outside filling antifreezing liquid in the enclosed space between the floating overhead guard.Floating top is made into inside and outside two-layer compound form, and the centre adds antifreezing liquid, can play the effect of counterweight like this by deicing fluid, has the function of certain insulation and sealing simultaneously again.
Axis of guide fixed support is installed above the said biomass pool body, and the axis of guide is installed at this axis of guide fixed support center, and this axis of guide is installed in the center sleeve of said floating top.Axis of guide performance guide effect.Axis of guide fixed support has positioning action to floating top.
Fixed support on the said biomass pool body inwall.Fixed support on the biomass pool body inwall also is that floating top is had certain location conduct.
Said biomass pool body outer wall top connects outer water seal, and said floating top is installed in this outer water seal, filling envelope air water in the said outer water seal.The methane-generating pit outer wall is established an outer water seal, and floating top is placed in the outer water seal, and along with the increase or the minimizing of gas, floating withstanding in the outer water seal fluctuated, rather than fluctuates in feed liquid.
The beneficial effects of the utility model are that the utility model compared with prior art has very big advantage to overcome the shortcoming that existing methane-generating pit type exists.The utility model adopts pool cover integrated, the floating top of floating is installed, on the fixed biomass pool body when giving full play to cover-floating type methane-generating pit advantage, floating cover and water seal tank have been avoided building separately, reduce and build the pond cost, reduce land area, can economize the land resource; The change of pond type has reduced earth volume, has reduced and has built the pond difficulty, and the while is big discharging under the situation of opening wide Chi Ding, has reduced the labour intensity of discharging, has improved safety coefficient, helps popularizing of biogas; Floating cover is installed in above the methane-generating pit that does not have the top, has air storage and top cover function concurrently, and under the gaseous tension effect, floating cover can fluctuate in feed liquid, makes it to become floating top, and floats the top by hydraulic seal, prevents that effectively biogas is excessive, and is safe and practical; Constant pressure air feeding has improved the efficient of methane cooker, lamp, makes peasants and herdsmen feel reliable and practical when using biogas, has improved agriculture and animal husbandry China Democratic National Construction Association pond enthusiasm, helps the construction of new socialist countryside; Since the raising of factor of created gase, and make the miniaturization of vigor pond, further reduced and built the pond cost; The utility model is simple in structure, is easy to fabrication and installation, has reduced cost of manufacture and use cost, has good social benefit and economic benefit.The utility model has further been installed whipping appts, has well solved the stirring problem of material in the pond, makes in the pond scum silica frost be not easy crust, be easy to fragmentation again, so the utilization ratio height of fermentation raw material, factor of created gase obviously improves, make methane-generating pit efficient increase about 30%, avoided slagging scorification and layering.
