Problems solved by technology

There are several deficiencies in the following aspects: on the one hand, it cannot meet the needs of farmers for biogas, and the amount of raw materials used by farmers for domestic fermentation has greatly exceeded the capacity of traditional biogas digesters. If it is some farms that raise livestock, then it is necessary to build more A biogas digester or even a dozen can meet the demand
However, due to the limitation of geological conditions, it is difficult to dig deep. The deeper the construction, the higher the cost, which limits the expansion of the biogas tank capacity.

Embodiment 1

[0039] This embodiment is a biogas digester with three pools in series structure, and the structure mainly includes a feed tank 2, a first fermentation tank 11 connected to the feed tank 2 through a feed pipe 21, a second fermentation tank 12, a third fermentation tank 13, and The third fermentation tank 13 is connected to the discharge tank 3 through a discharge pipe 31 , and the second fermentation tank 12 communicates with the first fermentation tank 11 and the third fermentation tank 13 through communication pipes 14 and 15 respectively. The arrangement structure of each structure of the biogas digester is shown in Figure 2, and the three fermentation ponds are arranged in a triangle to save land space.

[0040] The detailed internal structure and size of the biogas digester are shown in Figure 3. For the convenience of illustration, the three fermentation tanks are arranged in a straight line in Figure 3, and the feed tank 2 and the discharge tank 3 pass through the feed p...

Embodiment 2

[0046] As shown in Figure 6, a biogas digester with four tanks connected in series consists of a feed tank 2, a first fermentation tank 11, a second fermentation tank 12, a third fermentation tank 13, a fourth fermentation tank 4 and a discharge tank 3 Composed in series, the internal structure and working principle of its fermentation tank are basically the same as in Example 1. Compared with Example 1, this example has a larger capacity, and the fermentation feed liquid undergoes a longer reaction in the biogas digester, and the degree of degradation is more sufficient.

Embodiment 3

[0048] This embodiment is further improved on the basis of embodiment 2, and a special gas storage device is also provided. The gas storage device is composed of two gas storage tanks 51 and 52 connected at the bottom with the same structure as the biogas tank, and two hydraulic tanks 53 respectively connected with the gas storage tanks 52 . The tops of the gas storage tanks 51, 52 communicate with the gas storage ports on the tops of the respective fermentation tanks through pipelines 55, 56. During use, a certain amount of water is put into the hydraulic pool 53, and when the biogas chamber is formed on the top of the fermentation tank, the air pressure generated by the chamber will transport the biogas to the gas storage pools 51, 52 through the pipelines 55, 56 to form the same biogas chamber. Air chamber. The air chambers in the gas storage pools 51 and 52 form a certain pressure, which makes the liquid level of the hydraulic pool 53 rise to form a hydraulic seal. The f...

Abstract

The present invention relates to methane generating apparatus and sewage treating technology, and is especially one kind of coupled methane tank capable of treating great amount of domestic garbage to produce methane through complete degradation. Structurally, the coupled methane tank includes one feeding tank with gas outlet, two or more fermenting tanks, one discharging tank and connecting pipeline to form liquid flow passage. Through stage-by-stage reaction in the fermenting tanks, the present invention produces methane.

Description

technical field [0001] The invention relates to the field of biogas generating device and sewage treatment, more specifically to a conjoined biogas digester with super large capacity, capable of providing a large amount of biogas and simultaneously treating domestic sewage, feces and the like. technical background [0002] Biogas is a combustible gas. In the rural areas of our country, it is a combustible gas produced by using organic matter such as human and animal manure under anaerobic conditions through the energy metabolism and respiration of microorganisms in the biogas tank. There are 5 people in an ordinary farm family, and 4 pigs and 1 cow are kept normally. The human and livestock feces discharged annually can produce 810-950m3 biogas per year according to theoretical calculations. After deducting the loss of manure and the pressure loss of biogas fermentation, the actual usable biogas is 500-550m3 . In the prior art, the utilization of biogas is mainly realized t...
