Embodiment
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 the present invention's part embodiment, instead of whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not making under creative work prerequisite, and other embodiments all obtained, all belong to protection domain of the present invention.
As Figure 1-3, natural pond liquid uniflux promotes the equally distributed biogas fermentation device of bacterial classification, it comprises U-shaped fermentation pipeline 20, feed-pipe 11, discharging pipe 12, feed-pipe 11 and discharging pipe 12 are arranged at the two ends of U-shaped fermentation pipeline 20 and adjacently placed, water pressure house 30 is placed on U-shaped fermentation pipeline 20 top, water pressure house 30 and feed-pipe 11 link position are feed-pipe water vent 24, water pressure house 30 and discharging pipe 12 link position are discharging pipe water vent 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 discharging pipe gas block panel 26 with discharging pipe 12 link position place, livestock ight soil is poured into U-shaped fermentation pipeline 20 from feed-pipe 11 and is fermented, and natural pond liquid must overflow across feed-pipe gas block panel 22 and discharging pipe gas block panel 26, feed-pipe 11 and discharging pipe 12 are all uncovered settings, so the liquid level of U-shaped fermentation pipeline 20 both end sides is identical, when producing biogas in U-shaped fermentation pipeline 20, due to the restriction of feed-pipe gas block panel 22 and discharging pipe gas block panel 26, biogas constantly encloses at feed-pipe gas block panel 22, discharging pipe gas block panel 26, natural pond liquid liquid level and U-shaped fermentation pipeline 20 top and gathers between the space of conjunction, constantly increase along with biogas air pressure and when being greater than outdoor air pressure, natural pond liquid can rise from feed-pipe 11 and discharging pipe 12, and is flowed in water pressure house 30 by feed-pipe water vent 24 and discharging pipe water vent 26.
The top seal of water pressure house 30 and be connected with venting hole 32, keep air pressure in water pressure house 30 consistent with external pressure, rectilinear duct top, U-shaped fermentation pipeline 20 both sides is respectively arranged with effuser 40, effuser 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 natural pond liquid in water pressure house 30 falls after rise to U-shaped fermentation pipeline 20.
Feed-pipe, discharging pipe, fermentation pipeline and water pressure engine 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 height, but there is certain drawback in above-mentioned general planning, owing to fermentative routes is long, cause the strains'distribution in U-shaped fermentation system uneven, affect gas producing efficiency, and natural pond liquid mobility is poor in U-tube road, it is easy to crust on liquid upper strata, natural pond; Prior art adopt the technical scheme increasing natural pond liquid flowing be adopt manually to solve so that user uses biogas inconvenient.
For solving the technical problem of above-mentioned existence, the improvement that the present invention is further, thering is provided a kind of technical scheme not needing manual operation both can realize the natural pond liquid of U-shaped fermentation system and fully flow, and improve the cloth bacterium effect in U-shaped fermentation pipeline, concrete improved plan is as follows.
The first raising natural pond liquid flows and promotes the equally distributed scheme of bacterial classification.
The check valve of the unidirectional inflow water pressure house 30 of natural pond liquid that discharging pipe water vent 28 position is provided with in control fermentation pipeline 20, when biogas is assembled in a large number, natural pond liquid liquid level in feed-pipe 11 and discharging pipe 12 rises, natural pond liquid flows into water pressure house 30 from feed-pipe water vent 24 and discharging pipe water vent 28, contains in the natural pond liquid inflow water pressure house 30 of more bacterial classification and mix with the natural pond liquid of less bacterial classification that only has flowed into from feed-pipe water vent 24 near discharging pipe 12; When biogas is discharged from effuser 40, when making air pressure decline in U-shaped fermentation pipeline 20, natural pond liquid in water pressure house 30 is back in U-shaped fermentation pipeline 20, due to the restriction of check valve so that in water pressure house 30, natural pond liquid can only flow in feed-pipe 11, complete circulating of natural pond liquid, in the process, natural pond liquid more for bacteria containing amount is flowed in feed-pipe 11, has promoted being evenly distributed of bacterial classification, and the flowing utilizing natural pond liquid has promoted that fermentation raw material flows in fermentation system.
Above-mentioned promotion natural pond liquid flowing, drive the uniform scheme of strains'distribution, it is confined to flow near feed-pipe by bacterial classification more for content near discharging pipe, and the fermentation raw material in feed-pipe easily flows in water pressure house and results in blockage, due to the present invention's employing is U-shaped fermentation system, and overall natural pond liquid flowing mixing effect is not obvious.
2nd kind is improved natural pond liquid and flows and promote the equally distributed scheme of bacterial classification.
Flow at the first raising natural pond liquid and promote the basis of the equally distributed scheme of bacterial classification is improved, feed-pipe water vent 24 is provided with the check valve of liquid unidirectional inflow feed-pipe in natural pond in control water pressure house; By increasing check valve on feed-pipe water shoot, placing the foreign material such as fermentation raw material flows in water pressure house, and the natural pond liquid in pipeline that ferments can only by the unidirectional inflow water pressure house of discharging pipe water vent, can the natural pond liquid being more rich in bacterial classification be brought in water pressure house, promote that the equally distributed effect of bacterial classification is more obvious.
The third raising natural pond liquid flows and promotes the equally distributed scheme of bacterial classification.
The check valve being provided with liquid unidirectional inflow feed-pipe in natural pond in control water pressure house on feed-pipe water vent, the link position of feed-pipe water vent and water pressure house is lower than the link position of discharging pipe water vent and water pressure house.
