Three, utility model content
The purpose of this utility model is to overcome the defective that existing technology exists, and a kind of reflux type anaerobic digester that utilizes stalk to produce biogas is provided.
Be its above purpose, the utility model has adopted following technical scheme.Utilize stalk to produce the reflux type anaerobic digester of biogas, include fermentation jar, the feeding device of biogas transfer lime and natural pond slag delivery pipe, concrete structure is that described feeding device is an air pressure type feeder, the loading hopper of a high-pressure pipe and a strap brake door is arranged at its top, bottom connecting band gate feeding tube, feeding tube communicates with the top of fermentor tank.
Whipping appts by driven by motor is set in described air pressure type feeder.
Described air pressure type feeder top is connected with the strap brake door pipeline that communicates with fermentor tank.
Several opening for feeds that are connected with feeding tube evenly are set on described fermentor tank top.
Described fermentor tank is a vertical type cylinder shape.
In described fermentor tank, be provided with the heat energy sensing device that is connected with the external solar heat collector.
Superior part of the present utility model is:
1, adopts the air pressure type feeding style, can replenish needed raw material for fermentor tank automatically.
2, because having been carried out stirring, used crop material rubs the cured fat layer on destruction stalk surface, the contact area of increase stalk and natural pond liquid, raising fermentation efficiency.
3, the natural pond liquid in the fermentor tank is played back in the air pressure type agitator, mixes again with through the stalk of pulverizing, rubbing is handled, the blended stalk is the congee shape, and dry matter content (TS) can reach 6-20%; By easier being transported in the anaeroic digestor of congee shape stalk after stirring.When stalk mixes with natural pond liquid, take alr mode, it is floating to have solved stalk, is difficult for the difficulty of carrying; Using gas pressure is carried congee shape stalk, has solved the difficult problem of easy bite when slush pump is carried.
4, natural pond liquid is back in the anaerobic fermentation tank, has effectively utilized the fermentative action that is rich in microorganism in the liquid of natural pond.
5, fermentor tank is thin and tall cylindrical, and jar inner bottom part static pressure has prolonged the residence time of anaerobion effectively about 0.1MPa, and it is smooth and easy also to be beneficial to natural pond slag discharging simultaneously.
6, provide heat with solar energy collector for anaerobic fermentation tank, help keeping and improving the stalk fermentation temperature, thereby improve the gas deliverability of anaeroic digestor, be specially adapted to the northern area in winter.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment
The utility model structure is referring to accompanying drawing.
Embodiment 1: anaeroic digestor includes the fermentation tank body 1 and the feeding device of biogas transfer lime 10 and slag-drip opening 11, concrete structure is that described feeding device is an air pressure type feeder 2, the loading hopper 4 of a strap brake door high-pressure pipe 3 and a strap brake door is arranged at top, bottom connecting band gate feeding tube 5, the other end of feeding tube 5 communicates with the top of fermentor tank 1.This fairly simple device has been arranged, high pressure gas just can pass through inlet pipe 3, exert pressure in the container of pulverizing crop material is housed, stalk enters into fermentor tank 1 by feeding tube 5 and ferments, and the biogas that is produced is sent to the user through the biogas transfer lime 10 of fermentor tank; Gate on the discharge gate 11 of unlatching fermentor tank 1 bottom, natural pond slag can be discharged by discharge gate 11 under the effect of static pressure automatically.
Embodiment 2: the whipping appts 6 by driven by motor is set in described air pressure type feeder 2.Undressed stalk surface attachment wax layer, after the pulverizing rubbing of stalk through whipping appts 6, surperficial wax layer is destroyed, and has increased the contact area of stalk and natural pond liquid, has improved the speed of fermentation.
