Methane tank capable of facilitating slag removal

Abstract

The invention discloses a methane tank capable of facilitating slag removal. The methane tank comprises a methane tank body, wherein a feed port, a discharge port and a methane outlet are formed on the methane tank body; a gas storage chamber is arranged on the upper part in the methane tank body; a fermenting chamber is arranged on the lower part in the methane tank body; the bottom surface of the methane tank body is inclined; the feed port corresponds to the higher part of the inclined surface; and the discharge port corresponds to the lower part of the inclined surface. The bottom surface of the methane tank body is set to be the inclined surface, so when removing methane slag, a user only needs to draw out one part of methane liquid and return the methane liquid from the feed port (a feed pipe) to impact the bottom surface of the methane tank body to push the methane slag into the discharge port (a water pressure room) along with the inclined surface, and then can take out the methane slag conveniently from the discharge port (the water pressure room), so the user does not need to enter the fermenting chamber to remove the slag under a poisoning risk, and time and labor are saved; and in addition, the tank is stirred by the impact of the methane liquid, so that methane bacteria completely contact with fermenting materials newly entering the tank and yield of the methane is increased.

Description

technical field

[0001] The invention relates to a biogas pit, in particular to a biogas pit which is convenient for slag removal. Background technique

[0002] Biogas is a combustible gas produced by microbial fermentation of organic substances in an anaerobic environment at a certain temperature (above 10°C), concentration (6%) and pH (PH value 6-7). After the material enters the biogas tank for fermentation, the biogas residue that can no longer produce biogas falls into the bottom of the biogas tank. After continuous fermentation, more and more biogas residues are stored, which occupies the volume of the biogas tank and greatly reduces the gas production. Therefore, it is necessary to remove biogas residues regularly. Due to the structural limitations of existing biogas digesters, when removing biogas residues, the user must first pump out the biogas slurry with a water pump, and then enter the fermentation room from the discharge port (water pressure room) to remove bio...
