Embodiment
Like accompanying drawing 1, shown in 2, this biogas fermentation device is the vertical fermentor tank of right cylinder, and diameter is 16 meters; In tank body 12, vertically be provided with three dividing plates 13, dividing plate 13 is parallel to each other, and every dividing plate 13 spacings are 4 meters; Dividing plate 13 bottoms are fixed on tank body 12 base plates, and a side is fixed on tank body 12 inwalls, and opposite side and tank body 12 inwalls have a space 18; Distance between the width in space 18 and two dividing plates is suitable; Three dividing plates 13 are crisscross arranged, and top and tank body 12 are suitable for reading concordant and fixed by horizontal gusset, and three dividing plates 13 are separated into four relatively independent but sweathouses 19 of being interconnected with tank body 12 inside; Be provided with two groups of horizontal mixers at tank body 12 middle parts, whisking appliance is made up of agitator motor 8, stir shaft 14, agitating vane 16, and the dividing plate 13 in stir shaft 14 and the tank body 12 is vertical each other; Two ends are connected on tank body 12 walls through rotary seal; Union lever 15 holders are welded on the agitating vane 16 below agitating vane 16, about 30 centimetres an agitating vane 16 are set at every interval on the stir shaft 14; Agitating vane 16 is evenly staggered to be fixed on the stir shaft 14; Agitator motor 8 is located at the tank body 12 outer stir shafts 14 that connect, and union lever 15 is long as much as possible, does not run into tank body 12 inwalls with each agitating vane 16 and is as the criterion; Opening for feed 7 is located at the tank body outside of first dividing plate correspondence, the side that dividing plate links to each other with inner tank wall; Discharge port 11 is located at the tank body outside of last piece dividing plate correspondence, the side that dividing plate links to each other with inner tank wall; Discharge port 11 is lower than opening for feed 7, on discharge port 11, is connected with liquid conducting pipes; Domed top 5 outsides at tank body 12 are provided with three inspection- pits 2,4,6, inspection- pit 2,4,6 usefulness flange and blind plate sealings, and gas tube 1 is located on the sidewall of one of them inspection-pit 2 pit shaft with vapor pipe 3.
Be provided with an oblique TM disposed tubes 9 down in tank body 12 bottoms outsides, TM disposed tubes 9 outer end opening inner ends are sealed, and with filling water in the TM disposed tubes 9, and TM put into get final product during use.Be equipped with thermal insulation layer in tank body 12 outsides and tank body top.Be provided with floor heating device 10 in the bottom of tank body 12, floor heating device 10 connects solar heater or boiler or other heating units.On the tank wall of tank body 12 bottoms, be provided with a slag removing hole 17, when needing cleaning natural pond slag, the valve of opening on the slag removing hole 17 can carry out scarfing cinder.Be provided with a sump pump at discharge port 11, the sewage pump outlet connects opening for feed 7, starts sump pump, can natural pond liquid directly be squeezed into opening for feed 7 and circulate, and guarantees that opening for feed 7 has competent bacterial classification, and making raw material get into methane-generating pit just can very fast aerogenesis.
Three cat ladders are installed in methane-generating pit tank body outside, and one is to lead to 7, one of opening for feeds to lead to 11, one of discharge ports and lead to methane-generating pit domed top 5.
The opening for feed 7 and the discharge port 11 of methane-generating pit all have sunlight board sealing and leaving door and window; Advance the people and open door and window when checking,, often close winter and prevent that natural pond liquid from being frozen in case poison; Because feed inlet and outlet is bigger; In have forced stirrer to stir again, the natural pond slag can not sink and float, so do not have broken shell and the problem of slagging tap separately.
The working method of the utility model is:
1, start-up operation:
During charging for the first time, close the gas tube 1 on top, open vapor pipe 3, should advance pig manure or cow dung, concentration is low; 2-3% gets final product, and should add water and add excrement less, when reinforced, should often climb to opening for feed or discharge port inserts the degree of depth of checking feed liquid with waddy, and each charging is main with 30 centimeters; Advance a charging and should stop to advance two defective materials again in 3 days, when waiting the charging degree of depth to reach 1 meter, see the number of degrees of thermometer; If temperature is lower than 25 degree, should take the measure of heating, temperature increase with every day 1 degree for well; Be heated between 33-38 degree up to temperature, be interrupted charging successively in during this period, till discharge port 11 dischargings; Should open all stirrers 2 every day in charging, is no less than 15 minutes at every turn, fill it up with feed liquid after; Should stop charging and keep temperature; Often close vapor pipe 3 and open gas tube 1, and methane cooker is connected to sees on the gas tube 1 and can beat, as can't beat and should continue to close gas tube 1 and open vapor pipe 3; So after this experiment is closed vapor pipe 3 and is opened gas tube 1 to gas storage holder gas storage till beating.After this should increase inlet amount successively; The phenomenon of when increasing charging, putting not suddenly like discovery biogas should stop charging 2-3 days, the gas emptying of gas storage holder, opens a gas tube 1 to vapor pipe 3 again to close; Till lighting again, repeat above work again.
2, operation:
Behind the methane-generating pit normal gas producing, should adhere to charging every day more than 2 times, and every day, inlet amount should be stablized, each charging answered turn on agitator and natural pond liquid reflux pump to finish to stop in back 15 minutes up to charging in preceding 15 minutes.Answer constantly checked opening for feed 7 and discharge port 11, should in time handle, will see at least that thermometer, thermometer should remain between 33-38 degree one time in one day if any stopping up.Discharge port 11 feed liquids are automatically, and not stopping up does not need to handle, and answer constantly checked to watch the service condition of biogas; As find to have unexpected point not phenomenon, should stop charging, close gas tube 1, open vapor pipe 3; Gas emptying gas storage holder begins charging till lighting.Owing to turn on agitator every day, the phenomenon that do not crust is not so exist the broken shell phenomenon at normal operation period.Charging and discharging number at run duration liquid equate that the natural pond slag comes out along with one, do not need to consider separately to slag tap and go out natural pond liquid problem.
