The interior fermentation of fermentation pipeline 30 produces biogas and gathers in multiple fermentation zones, and along with the continuous increase of biogas amount, the biogas air pressure in fermentation zone also increases thereupon, and the natural pond liquid that extruding is fermented in pipeline 30 flows to feed pipe, discharge nozzle, cloth bacterium device; Biogas air pressure in fermentation pipeline further increases, and the natural pond liquid liquid level promoting in feed pipe 10, discharge nozzle 20 and cloth bacterium device 50 rises, first by the drainpipe 51 of cloth bacterium device 50, the natural pond liquid in fermentation pipeline 30 is flowed in water pressure chamber 40, when in water pressure chamber 40, the natural pond liquid liquid level of storage rises to the minimum point of discharge nozzle drainpipe 44, and by discharge nozzle drainpipe 44, the natural pond liquid in discharge nozzle 20 is flowed in water pressure chamber 40; While using the biogas in fermentation zone, the biogas air pressure in fermentation zone declines, and the natural pond liquid in water pressure chamber 40 is back in feed pipe 10 by feed pipe drainpipe 42 is unidirectional.

Its beneficial effect is: in water pressure chamber 40, export natural pond liquid by cloth bacterium device 50, effectively raise the mobile performance of intrasystem natural pond liquid, reach the uniform object of cloth bacterium in the mobile whipping process of natural pond liquid; While carrying natural pond liquid by discharge nozzle drainpipe to water pressure chamber, the natural pond liquid that discharge nozzle annex is rich in to bacterial classification is brought in water pressure chamber; When natural pond liquid in water pressure chamber refluxes, can only be delivered in feed pipe by feed pipe drainpipe, the natural pond liquid that is rich in bacterial classification is brought in feed pipe, by the mobile promotion charging of natural pond liquid, the fermentation raw material promoting in feed pipe gos deep into fermentation system inside.

The tenth kind of embodiment.

As Fig. 1, 2, shown in 3, the 9th kind of embodiment improves on the basis of the 4th kind of embodiment, be with four kinds of embodiment differences: on feed pipe drainpipe 42, be provided with the check valve of controlling liquid unidirectional inflow feed pipe 10 in natural pond in water pressure chamber 40, on discharge nozzle drainpipe 44, be provided with the check valve of controlling liquid unidirectional inflow water pressure chamber 40 in natural pond in discharge nozzle 20, on the drainpipe 51 of cloth bacterium device 50, be provided with the check valve in the unidirectional inflow water pressure chamber 40 of natural pond liquid in controlled fermentation pipeline 30, drainpipe 51 tops of cloth bacterium device extend in water pressure chamber 40, the horizontal plane at the minimum point place of discharge nozzle drainpipe 44 and water pressure chamber 40 link positions is lower than the horizontal plane at the drainpipe 51 minimum point places, top of cloth bacterium device 50.

The interior fermentation of fermentation pipeline 30 produces biogas and gathers in multiple fermentation zones, and along with the continuous increase of biogas amount, the biogas air pressure in fermentation zone also increases thereupon, and the natural pond liquid that extruding is fermented in pipeline 30 flows to feed pipe, discharge nozzle, cloth bacterium device; Biogas air pressure in fermentation pipeline further increases, and the natural pond liquid liquid level promoting in feed pipe 10, discharge nozzle 20 and cloth bacterium device 50 rises, and first flow in water pressure chamber 40 by discharge nozzle drainpipe 44, when natural pond liquid liquid level in water pressure chamber 40 rises to the drainpipe 51 top lowest point of cloth bacterium device 50, the natural pond liquid in fermentation pipeline 30 flows in water pressure chamber 40 by the drainpipe 51 of cloth bacterium device 50 again; While using the biogas in fermentation zone, the biogas air pressure in fermentation zone declines, and the natural pond liquid of water pressure chamber 40 interior storages can only be back in feed pipe 10 by feed pipe drainpipe 42 is unidirectional, completes circulating of natural pond liquid.

Its beneficial effect is:, the natural pond liquid that is rich in bacterial classification is brought in water pressure chamber during to the interior conveying of water pressure chamber 40 natural pond liquid by discharge nozzle drainpipe 44, and carried natural pond liquid by cloth bacterium device to water pressure chamber, promote intrasystem natural pond liquid to flow; Natural pond liquid in water pressure chamber 40 refluxes by feed pipe drainpipe, and the natural pond liquid that is rich in bacterial classification brings in feed pipe, and promotes charging, and the natural pond liquid that is rich in bacterial classification is brought in feed pipe 10.

The 9th kind of embodiment is compared with the tenth kind of embodiment, the 9th kind of embodiment mainly lays particular emphasis on and promotes flowing of natural pond liquid, being uniformly distributed of mobile drive bacterial classification by natural pond liquid, the tenth kind of embodiment mainly lays particular emphasis on to be brought near the natural pond liquid that is rich in bacterial classification discharge nozzle in feed pipe into, promote the natural pond liquid recycle stream that is rich in bacterial classification to move, the 9th kind of embodiment and the tenth kind of embodiment are all that the natural pond liquid in water pressure chamber 40 is passed through in the unidirectional inflow feed pipe 10 of feed pipe drainpipe 42, promote near the fermentation raw material of feed pipe 10 and flow into fermentation system inside.

To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention. To be apparent for those skilled in the art to the multiple amendment of these embodiment, in the present invention, defined General Principle can, in the situation that not departing from spirit of the present invention or scope, realize in other embodiments.
