In fermentation pipeline, fermentation produces biogas and in fermentation pipeline inner accumulated, along with the increase of biogas air pressure, natural pond liquid in extruding fermentation pipeline flows in feed-pipe, discharge nozzle and cloth bacterium device, under the control of check valve, natural pond liquid in fermentation pipeline is first by the unidirectional inflow water pressure house of water shoot of cloth bacterium device, when natural pond liquid liquid level in water pressure house reaches the extreme lower position of discharge nozzle water shoot, the natural pond liquid in discharge nozzle is again by the unidirectional inflow water pressure house of discharge nozzle water shoot; When using the biogas of the storage in fermentation pipeline, biogas air pressure in fermentation pipeline declines, the natural pond liquid stored in water pressure house is by the unidirectional inflow feed-pipe of feed-pipe water shoot, complete circulating of natural pond liquid, natural pond liquid in water pressure house is back in feed-pipe process, the natural pond liquid being rich in bacterial classification to be brought in feed-pipe and the natural pond liquid of flowing promotes that fermentation raw material flows in fermentation system, reach the effect promoting charging.
8th kind of scheme compares with the 9th kind of scheme, 8th kind of scheme mainly lays particular emphasis on circulating of natural pond liquid, and the natural pond liquid being rich in bacterial classification is brought in water pressure house, utilize the backflow of natural pond liquid in water pressure house, impel the natural pond liquid being rich in bacterial classification to flow into each position of fermenting in pipeline, improve being uniformly distributed of bacterial classification; 9th kind of scheme mainly lays particular emphasis on the convection agitation of natural pond liquid, first natural pond liquid in fermentation pipeline flow in water pressure house by the cloth tube road of cloth bacterium device, facilitate the natural pond liquid convection agitation in whole fermentation system, utilizing the convection agitation of natural pond liquid, promote being uniformly distributed of bacterial classification, improve the fermentation efficiency of whole fermentation system.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, the General Principle defined in the present invention when not departing from spirit of the present invention or scope, can realize in other embodiments.Therefore, the present invention can not be defined to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
