Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiment。Based on the embodiment in the present invention, those of ordinary skill in the art under not making creative work premise, the every other embodiment obtained, broadly fall into scope。
As Figure 1-3, biogas slurry one-way flow promotes the equally distributed biogas fermentation device of strain, it includes U-shaped fermentation pipeline 20, feed pipe 11, discharge nozzle 12, feed pipe 11 and discharge nozzle 12 are arranged at two ends and the placed adjacent of U-shaped fermentation pipeline 20, water pressure chamber 30 is placed on U-shaped fermentation pipeline 20 top, water pressure chamber 30 and feed pipe 11 link position are feed pipe osculum 24, water pressure chamber 30 and discharge nozzle 12 link position are discharge nozzle osculum 28, U-shaped fermentation pipeline 20 arranges a feed pipe gas block panel 22 with feed pipe 11 link position place, U-shaped fermentation pipeline 20 arranges a discharge nozzle gas block panel 26 with discharge nozzle 12 link position place；Excrement of animals is poured into U-shaped fermentation pipeline 20 from feed pipe 11 and is fermented, and it is all uncovered setting that biogas slurry must overflow across feed pipe gas block panel 22 and discharge nozzle gas block panel 26, feed pipe 11 and discharge nozzle 12, so the liquid level of U-shaped fermentation pipeline 20 both end sides is identical；When producing biogas in U-shaped fermentation pipeline 20, restriction effect due to feed pipe gas block panel 22 and discharge nozzle gas block panel 26, biogas constantly gathers between the space that feed pipe gas block panel 22, discharge nozzle gas block panel 26, biogas slurry liquid level and U-shaped fermentation pipeline 20 top enclose, along with biogas air pressure constantly increases and during more than outdoor air pressure, biogas slurry can rise from feed pipe 11 and discharge nozzle 12, and is flowed in water pressure chamber 30 by feed pipe osculum 24 and discharge nozzle osculum 26。
The top of water pressure chamber 30 seals and is connected to steam vent 32, keep water pressure chamber 30 internal gas pressure consistent with external pressure, rectilinear duct top, U-shaped fermentation pipeline 20 both sides is respectively arranged with discharge 40, discharge 40 is provided with valve body, the valve body when not using biogas；When using biogas, opening valve body, the air pressure in U-shaped fermentation pipeline 20 reduces, and the biogas slurry in water pressure chamber 30 falls after rise to U-shaped fermentation pipeline 20。
Feed pipe, discharge nozzle, fermentation pipeline and hydraulic press all can adopt mixed earth to build or adopt PVC pipeline connection to make or adopt glass-reinforced plastic material to make。
What the present invention adopted is U-shaped fermentation system, its fermentative routes is long, gas producing efficiency is high, but there is certain drawback in above-mentioned basic scheme, owing to fermentative routes is long, cause that the strains'distribution in U-shaped fermentation system is uneven, affect gas producing efficiency, and biogas slurry poor fluidity in U-tube road, it is easy to crust on biogas slurry upper strata；Adopting the technical scheme increasing biogas slurry flowing in prior art is adopt manually to solve so that user uses biogas inconvenient。
For solving the technical problem of above-mentioned existence, the present invention further improves, thering is provided a kind of and manual operation both need not can realize the technical scheme that the biogas slurry of U-shaped fermentation system fully flows, and improve the cloth bacterium effect in U-shaped fermentation pipeline, concrete improved plan is as follows。
