Manufacturing method of rural household biogas digester

Abstract

The invention relates to a biogas pool for rural residents and manufacturing method thereof. The biogas pool comprises a fermenting tank (1), a gas storage tank (2) and a waste material tank (3); wherein one side of the fermenting tank (1) is connected with the waste material tank (3), the gas storage tank (2) is arranged above the fermenting tank (1) and is communicated with the fermenting tank (1), the joint part of the fermenting tank (1) and the waste material tank (3) is provided with an arch door (7), the central position of the arch door (7) is provided with a waste material hole (8); the central position of the top of the gas storage tank (2) is provided with an air outlet (4), the middle part of one side of the gas storage tank (2) is provided with a feed opening (5), the upper part of one side of the waste material tank (3) is provided with a discharging hole (9). The invention has the beneficial effects that: manufacture is simple, cost is low, energy source is saved, and biogas pool of 6-12m<3> can be built.

Description

technical field [0001] The invention relates to the technical field of rural household biogas production, in particular to a rural household biogas digester and a manufacturing method thereof. Background technique [0002] At present, biogas digesters have been widely used in rural areas. The feeding pipes of existing biogas digesters are usually fixed on the fermentation tank and cannot move up and down at will, and the bottom surface of the feeding pipe is lower than the height of the passage between the fermentation tank and the waste tank, which is not conducive to raw materials. Flowing to the channel, the fermentation is insufficient, and raw materials are wasted; the top of the gas storage tank is sealed with a sealing plate, and there is an air outlet on the sealing plate. Air leakage; when in use, the fermentation tank is connected to the waste material tank, and it is easy for raw materials to flow into the waste material tank, wasting raw materials and polluting t...
