Description
Technical field
The utility model relates to a kind of methane-generating pit.
Background technology
Along with China's livestock industry continues, fast-developing, industrial scale and intensification degree improve constantly, built a collection of big-and-middle-sized livestock and poultry farm in succession.The movement that produces in its feeding is stacked everywhere, any discharging of sewage that flushing livestock and poultry house produces etc., the directly health of pollution effect people fowl.Culture the owner and do not handled, it is improper to use, so that surpasses the natural purifying ability in soil and storehouse, the pool, river, thereby contaminated soil, water source etc. form public hazards, and current people recognize the serious consequence of plant's environmental pollution.Biogas engineering is to administer to pollute to realize manure resource digestibility and utilization, effective antipollution optimal path.But big-and-middle-sized biogas engineering has high input, implements difficulty, makes most middle-size and small-size plants be unable to reach.The middle-size and small-size biogas engineering utilization ratio of existing popularization is low, and the sewage disposal cycle is long, the demand of the livestock and poultry cultivation that is far from suitable.
Summary of the invention
For the handling problem of the movement that solves middle-size and small-size plant, sewage etc., the utility model provides a kind of connection ball that is applicable to middle-size and small-size plant multistage ferment biomass pool of heating.
Concrete technical solution is as follows:
The connection ball multistage ferment biomass pool of heating comprises charging pond, fermentation vat, material-output tank and separate tank, comprises the fermentation vat of two connections, and its top is being communicated with gas pipe line by arm respectively, and charging pond and material-output tank are being communicated with separate tank by circulating pipe respectively; Described fermentation vat is a spheroidal, connect in the fermentation vat of two connections and be provided with heating tube, heating tube is provided with well heater and heating cycle pump, and well heater also is being communicated with the heating cycle flexible pipe, the other end of heating tube is being communicated with the other end of heating cycle flexible pipe, and heating tube is provided with the heating cycle pump;
Circulating pipe between described charging pond and the material-output tank is provided with the circulation gate valve, and the exit of material-output tank is provided with recycle pump, and the ingress of separate tank is provided with blowoff gate valve.
The middle part is respectively equipped with 8 font circulation heating tubes in two spheroidal fermentation vats, and 8 font circulation heating tubes are connected on the heating tube.
Described heating cycle flexible pipe is positioned at the fermentation vat bottom of two connections.
The utility model is a raw material with middle-size and small-size livestock and poultry farms in scale fecal sewage, and adopting circulation stirring, multistage anaerobic digestion, improving leavening temperature is the efficient gas production system engineering of one.Its useful technique effect is embodied in the following aspects:
1, the utility model rational in infrastructure, save material, be fit to batch production production, the spherical series connection of connection anaerobically fermenting pond prolongs yeast phase, and isolates biogas different steps institute aerogenesis body (produce acid gas, produce methane gas) and improve the biogas utilization rate.
2, realize heating purpose by being installed in heat tubular axis and the loop hose of cloth at the bottom of the pond of horizontal and vertical 8 fonts in the pond.Utilize biogas that methane-generating pit self produces or sun power, electric energy to heat, thereby temperature, thermophilic fermentation in realizing improve factor of created gase, accelerate plant's waste water control speed, realize zero release to fermentation vat.
3, in the pond in length and breadth heating tube be the outstanding middle part, anaerobically fermenting pond that is contained in, irregularly rotation, fermented product in the agitated pool has enlarged the fermented bacterium contact surface, has accelerated fermenting speed, improves factor of created gase.
4, residual sea water pump and residual sea water pump gate valve are installed on the pipeline between material-output tank of the present utility model and the separate tank when closing the drainage conduit gate valve, the fermented product of discharge port flows into opening for feed under the effect of water pump, played inoculation, stirring action.When closing to opening for feed recycle pump gate valve, the methane-generating pit fermented product is discharged into natural pond slag, natural pond liquid separate tank.
Description of drawings

Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, the connection ball multistage ferment biomass pool of heating comprises fermentation vat 2, material-output tank 5 and the separate tank 9 of charging pond 1, two connections, be communicated with by communicating pipe 3 between the fermentation vat 2 of two connections, the top is being communicated with gas pipe line 15 by arm respectively, the other end of gas pipe line 15 is equipped with biogas storage cabinet 17, the place, air outlet of fermentation vat 2 is equipped with gas transmission gate valve 10, and charging pond 1 and material-output tank 5 are being communicated with separate tank 9 by circulating pipe 4 respectively;
Being separately installed with 8 font circulation heating tubes, 11,8 font circulation heating tubes 11 in the middle part of in two spheroidal fermentation vats 2 is connected on the heating tube 13.
On the circulating pipe 4 between charging pond 1 and the material-output tank 5 circulation gate valve 7 is installed, the exit of material-output tank 5 is equipped with recycle pump 6, and the ingress of separate tank 9 is equipped with blowoff gate valve 8.
After the fermentation raw material swine manure wastewater enters anaerobically fermenting pond 2 fermentation gas by charging pond 1, fermented product flows into next spherical anaerobically fermenting pond through spherical fermentation vat communicating pipe 3 under the effect of recycle pump 6, after finishing, fermentation flows into material-output tank 5 again, material in the material-output tank 5 enters biogas residue and biogas liquid separate tank 9 under the effect of recycle pump 6.
Well heater 12 is given medium heating in the circulation heating tube 13, and the medium that heats under the effect of heating cycle pump 14 flows into placed in-line 8 font circulation radiating pipes 11 by heating tube 13, gives fermented product heating in the fermentation vat 2.Cooling back medium flows to well heater 12 circulation heating, warm thermophilic fermentation in the realization again by the heating cycle flexible pipe 16 that is installed in the bottom, pond.
The fermented product in charging pond 1 flows into fermentation vat 2 under the effect of the recycle pump 6 in material-output tank 5 exits, flow into material-output tank 5 again, and the methane bacterial classification in the material-output tank 5 is fully contacted with the fermentation raw material that newly advances, and flows to stir to accelerate fermenting speed.
The gas that fermentation vat 2 is produced enters gas storage holder biogas 17 by the gas of gas pipe line 15,70%, is used for generating electricity, lives and use energy.30% gas is used for well heater 12 and heats warm thermophilic fermentation in the realization for the interior fermentation raw material of methane-generating pit.
