Problems solved by technology
In the process of biogas production, it is necessary to continuously add fermentation raw materials to the biogas tank, and in the process of microbial fermentation, sediment will be continuously generated. Over time, the sediment will continue to accumulate, and the accumulated sludge will seriously affect the fermentation. efficiency
In addition, these sediments are also difficult to clean up, and the equipment needs to be restarted before it can run

Embodiment Construction
[0011] like figure 1 as shown, figure 1 It is a structural schematic diagram of a sedimentation and fermentation integrated biogas generating device proposed by the present invention.
[0012] refer to figure 1 , the present invention proposes a sedimentation and fermentation integrated biogas generating device, including a sedimentation tank 1, a first solenoid valve 4, a driving device 5, a stirring assembly 6, a feeding pump 7, a feeding pipe 8, a fermentation tank 9, a liquid feeding pipe 12, a feeding Air pipe 13 and second solenoid valve 14;
[0013] The sedimentation tank 1 is separated by the first partition to form the stirring part 2 and the sedimentation part 3. The first partition is provided with a feeding hole, and the first electromagnetic valve 4 is arranged in the feeding hole; the driving device 5 is arranged on the sedimentation tank 1, and its The output shaft can drive the stirring assembly 6 to rotate, and the stirring assembly 6 includes a stirring ro...

The invention provides a sedimentation and fermentation integrated biogas generator. The sedimentation and fermentation integrated biogas generator is characterized in that a sedimentation pool is partitioned into a stirring portion and a sedimentation portion through a first partition, a feeding hole is formed in the first partition, and a first electromagnetic valve is arranged in the feeding hole; a driving unit is arranged on the sedimentation pool, and a stirring component comprises a stirring rod and a stirring blade; a feeding pump is arranged in the sedimentation pool with the feeding port located at the preset position of the sedimentation portion and the discharging outlet extending into a fermentation pool through a feeding pipe, the fermentation pool is partitioned into a fermentation portion and a liquid storage portion through a second partition, the fermentation portion is communicated with the liquid storage portion through a liquid delivery pipe, the fermentation portion is communicated with the feeding pump through the feeding pipe and is communicated with an outer biogas storage unit through a biogas feeding pipe, a running-through liquid feeding hole is arranged between the liquid storage portion and the stirring portion, and a second electromagnetic valve is arranged in the liquid feeding hole. By the arrangement, the fermentation process is stable, sediment in the fermentation portion is less, frequent sediment suction is not needed, and biogas-producing efficiency is high.
Description
technical field [0001] The invention relates to the technical field of biogas digesters, in particular to a sedimentation and fermentation integrated biogas generating device. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity, and pH. In the process of biogas production, it is necessary to continuously add fermentation raw materials to the biogas tank, and in the process of microbial fermentation, sediment will be continuously generated. Over time, the sediment will continue to accumulate, and the accumulated sludge will seriously affect the fermentation. efficiency. In addition, these sediments are also difficult to clean up, and the equipment needs to be restarted before it can run. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a precipitation and fermentation integrated...
