Water pressure chamber 50 top uses and seals structure, prevents foreign material from falling in water pressure chamber 50, and the connection of water pressure chamber 50 top has the exhaustor 56 communicated with air, it is ensured that water pressure chamber 50 internal gas pressure is consistent with external atmosphere pressure.
It is connected by water guide pipeline between one grade fermemtation system 10 with second order fermentation system 40, concrete, the first aqueduct 22 that the secondary feed tube 42 with second order fermentation pipeline 41 is connected it is provided with on one grade fermemtation pipeline, it is connected between the water pressure chamber 50 of second order fermentation system 40 and one grade fermemtation pipeline and has the 3rd aqueduct 32, for controlling biogas slurry circulating in whole fermentation system, the check valve in the biogas slurry unidirectional inflow second order fermentation pipeline controlled in one grade fermemtation pipeline it is provided with on first aqueduct 22, the check valve in the biogas slurry unidirectional inflow one grade fermemtation pipeline controlled in water pressure chamber 50 it is provided with on 3rd aqueduct 32；Circulate for improving the biogas slurry in whole fermentation system, promote that strain is uniformly distributed, the second aqueduct 24 that two grades of discharge nozzles 44 with second order fermentation pipeline 41 are connected it is also provided with on one grade fermemtation pipeline, same, the check valve in the biogas slurry unidirectional inflow second order fermentation pipeline controlled in one grade fermemtation pipeline it is provided with on second aqueduct 24, two sides of water pressure chamber 50 connect the 3rd aqueduct 32 and the 4th aqueduct 34 respectively, and the 4th aqueduct 34 is provided with the check valve in the biogas slurry unidirectional inflow one grade fermemtation pipeline controlled in water pressure chamber 50；Preferably, the horizontal plane at the first aqueduct 22 and the second minimum point place, aqueduct 24 top is less than the horizontal plane of the 3rd aqueduct 32 and the 4th aqueduct 34 and water pressure chamber link position minimum point place.
Owing to the secondary feed tube of second order fermentation system needs charging and two grades of discharge nozzles to need discharging, for preventing second order fermentation system from causing obstruction in fermentation raw material falls in fill process the first aqueduct 22, and prevent second order fermentation system from biogas residue falls into during discharging the second aqueduct 24, causing obstruction, as shown in Figure 6,7, at the link position of the first aqueduct 22 and the second aqueduct and secondary feed tube 42 and two grades of discharge nozzles 44, it is provided with the baffle plate 45 of arc；When the biogas slurry in one grade fermemtation system 10 flows in secondary feed tube, may advantageously facilitate the fermentation raw material in secondary feed tube and go deep in second order fermentation pipeline.
Owing to the position at one grade fermemtation pipeline place is less than second order fermentation pipeline, produces in process of methane for fermentation in preventing one grade fermemtation pipeline, the biogas slurry in one grade fermemtation pipeline is overflowed by turnover barrel.As shown in Figure 4, the height H1 on the horizontal plane ground at turnover place, barrel top should be more than the horizontal plane at the peak place of the water pressure chamber 50 of second order fermentation system；Simultaneously, on one grade fermemtation pipeline, the biogas of inner accumulated need to be discharged by airway 18, obstruction is caused for entering biogas slurry in preventing airway, being connected between airway 18 with one grade fermemtation pipeline and have inducing QI post 17, the height H2 on the horizontal plane ground at place, inducing QI post 17 top should be more than or equal to H1.
There is various disadvantages in existing marsh gas fermenting system, such as, biogas slurry poor fluidity causes biogas slurry upper strata to be crusted, and cause the strains'distribution in fermentation system uneven owing to biogas slurry convection effects is inconspicuous, reducing the factor of created gase of whole fermentation system, for solving above-mentioned various problems, the present invention devises the device of multiple promotion biogas slurry convection agitation, by promoting the convection agitation of biogas slurry, solution strains'distribution is uneven and solves crust problem.
One grade fermemtation system 10 promotes that biogas slurry flows, and drives the equally distributed embodiment of strain.
