Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Referring to fig. 1, the embodiment discloses a methane tank, which comprises a reaction tank 1, wherein one side of the reaction tank 1 is connected with a feeding tank 2, the other side of the reaction tank 1 is connected with a waste tank 3, a methane bag 4 is connected in the reaction tank 1, the methane bag 4 is a soft bag, a feeding port 21 is arranged at the lower part of the feeding tank 2, the feeding port 21 is arranged in a downward inclined manner, a discharging port 31 is arranged at the lower part of the waste tank 3, the feeding port 21 and the discharging port 31 are both communicated with the methane bag 4, an air outlet is arranged at the upper part of the methane bag 4, and an air guide pipe 5 is connected at the air outlet.
Wherein, the anaerobic fermentation reaction for generating the marsh gas is carried out in the marsh gas bag 4, the marsh gas generated in the marsh gas bag 4 finally enters the gas guide tube 5 through the top gas outlet and is conveyed to the marsh gas appliance by the gas guide tube 5.
According to the methane tank structure, the closed integrated methane bag 4 is used as a container for anaerobic reaction, the structure is simple, the installation is convenient, and the anaerobic reaction is more favorably carried out.
The material outlet 31 and the material inlet 21 are not arranged on the same side, so that not only can the reacted materials be discharged in time, but also new materials can be reserved in the biogas bag 4, and the internal reaction of the biogas bag 4 can be carried out fully.
In one embodiment, the gas-guide tube 5 is connected with a gas valve 6 and a gas-liquid separator 7, the gas valve 6 is used for controlling the on-off of the gas-guide tube 5, and the gas-liquid separator 7 is used for separating liquid in the methane.
In one embodiment, the height of the feeding port 21 is greater than that of the discharging port 31, so as to facilitate feeding, and simultaneously, a certain amount of new materials can be retained inside the biogas bag 4, so as to facilitate the full implementation of anaerobic fermentation.
In one embodiment, the height of the discharge port 31 is greater than the height of the bottom of the waste material tank 3, so that the discharge port 31 is kept at a certain distance from the bottom of the waste material tank 3, thereby avoiding discharging waste materials generated in the biogas bag 4 at one time, reducing corresponding anaerobic bacteria and causing excessive damage to the reaction environment.
Further, the distance between the discharge port 31 and the bottom of the waste tank 3 is 10-15 mm.
In one embodiment, the upper part of the reaction tank 1 is detachably connected with an explosion-proof net, an accommodating space is formed between the explosion-proof net and the reaction tank 1, and the biogas bag 4 is positioned in the accommodating space.
Further, the inner wall of the reaction tank 1 is connected with a hook, and an explosion-proof net is hooked on the hook.
In one embodiment, the upper part of the waste tank 3 is arranged at a scum outlet (not shown in the figures). If scum is generated in the waste material introduced into the waste material tank 3 through the discharge port 21, the scum can be discharged through a scum outlet.
In one embodiment, the biogas bag 4 is connected with a pressure sensor to detect the internal pressure of the biogas bag 4 in real time, so as to facilitate timely judgment of the biogas generation condition inside the biogas bag 4.

In one embodiment, the reaction tank 1, the feed tank 2 and the waste tank 3 are all constructed of concrete.
In one embodiment, a plurality of biogas bags 4 can be connected to the reaction tank. For example, the system is designed to produce 11 methane per day, and the methane production generally accounts for 20% of the methane tank, i.e. the volume of the methane tank 55, so that 5 10 methane bags (3700 mm long by 1800mm wide by 1500mm high) and 1 5.805 methane bag (2150 mm long by 1800mm wide by 1500mm high) can be used together.
The use method of the methane tank in the embodiment comprises the following steps: raw materials for generating biogas, such as water hyacinth, pig manure, straw and the like, are pretreated and then placed in the feeding tank 2, and enter the biogas bag 4 from the feeding port 21, so that anaerobic fermentation reaction is generated inside the biogas bag 4 to generate biogas, the biogas is finally output by the gas guide pipe 5 for use, and in addition, waste materials (biogas slurry and biogas residues) generated after anaerobic fermentation reaction inside the biogas bag 4 enter the waste material tank 3 through the discharging port 31. And in the process of generating anaerobic fermentation reaction inside the biogas bag 4, a biogas layer, a clear water layer, a biogas liquid layer and a biogas residue layer are formed from top to bottom.
