The working process of the omnibearing dynamic anaerobic fermentation tank comprises the following steps:
2. gas production and use process
As shown in fig. 4, step one: after fermentation raw materials enter the fermentation chamber 3 from the feeding pipe 16, anaerobic fermentation is carried out in the fermentation chamber 3, the switch of the exhaust pipe is closed, the amount of biogas is increased along with the progress of the fermentation process, the biogas is stored in the gas storage chamber, so that the air pressure in the gas storage chamber is gradually increased, the air pressure acts on the biogas slurry in the fermentation chamber 3 and pushes the biogas slurry in the fermentation chamber 3 to flow into the top return liquid storage tank 13 above the tank top 9 through the feeding pipe 16 and the communicating pipe 4, the biogas slurry flowing into the feeding pipe 16 and the communicating pipe 4 from the fermentation chamber 3 forms a plurality of water streams, and the plurality of water streams stir the biogas slurry at the bottom in the fermentation chamber 3, promote the progress of the fermentation process and improve the efficiency of gas production. In the process of gas production, the liquid level of the fermentation chamber 3 gradually drops, and the liquid level in the top return liquid storage tank 13 gradually rises.
Step two: and opening an exhaust pipe switch, discharging the biogas in the gas storage chamber 10 through the exhaust pipe 7 for a user to use, wherein at the moment, as the biogas pressure in the gas storage chamber 10 is reduced, the biogas slurry in the feed pipe 16 and the communicating pipe 4 flows back to the fermentation chamber through an elbow to form water flow, the water flow stirs the biogas slurry in the fermentation chamber from top to bottom, impacts sludge at the bottom of the fermentation tank body 1 to form an all-directional dynamic process in the fermentation tank body 1, finally, the liquid level in the fermentation chamber 3 rises again, and the liquid level in the top-return liquid storage tank 13 gradually falls.
The number of the communicating pipes 4 can be multiple, preferably 5, and 5 communicating pipes 4 and the feed pipe 16 are uniformly arranged along the circumferential direction of the inner wall of the fermentation tank body 1, so that when biogas in the gas storage chamber 10 pushes the biogas slurry to enter the top return liquid storage tank 13 from the communicating pipes 4 and the feed pipe 16, 6 strands of water flow can be formed, and the 6 strands of water flow stir the biogas slurry in the fermentation chamber 10, further promoting the fermentation, and improving the efficiency of gas production. Alternatively, the communication between 5 communicating pipes 4 or the feeding pipe 16 and the top return liquid pool 13 can be closed, and only one communicating pipe is kept to be communicated with the top return liquid pool 13, so that the fermentation liquid forms a water flow with a speed higher than that of 6 water flows, and the sludge at the bottom of the fermentation chamber 3 can be impacted to prevent the sludge from accumulating.
More specifically, each of the communicating pipes 4 and the parts of the feeding pipe 16 above the tank top are connected with an elbow 14, the elbow 14 is preferably a right-angled elbow, one end of the right-angled elbow is communicated with the feeding pipe 16 or the communicating pipe 4, and the other end of the right-angled elbow is communicated with the top return liquid storage tank 13 and has an upward opening.

3. Extreme gas generating state
As shown in fig. 6, as the anaerobic fermentation process in the fermentation chamber 3 proceeds, the amount of generated biogas increases, and when the gas storage chamber 10 is filled with biogas and the pressure reaches a certain value, the biogas slurry in the fermentation chamber 3 is pushed into the top return liquid storage tank 13 by the biogas until the liquid level in the fermentation chamber 3 is lowered to the point that the bottom of the cylinder 20 of the manhole 5 is exposed out of the liquid level, the regenerated biogas overflows through the manhole 5 and enters the atmosphere, and at this time, the pressure value of the biogas reaches the maximum value, the liquid level in the fermentation chamber does not further decrease, and the pressure is maintained stably.
Therefore, when the amount of the generated biogas is small, the pressure value of the biogas is small, the pressure in the gas storage chamber 10 is not enough to push the biogas slurry in the fermentation chamber 3 to the top of the top to return to the liquid storage tank 13, and the generated biogas is stored in the gas storage chamber 10; along with the gradual increase of the biogas yield, when the liquid level in the fermentation chamber 3 is pushed into the top-return liquid storage tank 13 by the pressure in the gas storage chamber 10, on one hand, the formed water flow stirs the fermentation chamber 3 to promote fermentation and gas production, on the other hand, the exhaust valve 6 on the exhaust pipe 7 is opened, biogas is discharged from the exhaust pipe 7 for use by gas equipment, along with the gradual increase of the speed and the amount of the generated biogas, the pressure is gradually increased, biogas slurry in the fermentation chamber 3 is continuously pushed to flow into the top-return liquid storage tank 13, when the inner surface in the fermentation chamber 3 is downward to the position below the bottom of the cylinder body 20 of the manhole 5, the generated redundant gas is discharged from the cylinder body 20 of the manhole 5, at the moment, the liquid level stops descending, the pressure stops rising continuously, and therefore, the cylindrical oxygen fermentation tank provided by the invention, the biogas pressure can be kept within a certain range, the pressure value can be ensured not to be too large or too small, and the problem that the biogas utilization rate is reduced because the biogas pressure in the biogas digester of the fermentation tank in the prior art is unstable, has large fluctuation and is not beneficial to the sufficient combustion of the biogas in biogas appliances such as lamps, cookers and the like is solved.
The utility model provides an all-round developments anaerobic fermentation jar can be every day dynamic carry out the stirring of omnidirectional water impact to the natural pond liquid and the silt of the internal 1 of fermentation tank, form the all-round developments of the internal 1 of fermentation tank, can promote going on of fermentation process, be favorable to improving product gas efficiency.
