Novel domestic biogas digester

Abstract

The invention relates to a novel domestic biogas digester. A round material collecting pit for filling materials is formed in the middle of a biogas digester body, a pit cover is arranged at the upper end of the material collecting pit, a feed pipe penetrating through the pit cover and an exhaust pipe are installed on the pit cover, the other end of the feed pipe is fixed in a material storage platform higher than the biogas digester body at the horizontal position, and the other end of the exhaust pipe is communicated with a gas storage device. Dirt can be smoothly transported to the material collecting pit through the material storage platform at high level under the action of gravity, after being generated, the methane can be sucked into the gas storage device through the exhaust pipe under the action of an exhaust fan, then the methane is transported to each household through a gas pipeline, and therefore, the novel domestic biogas digester has the characteristics of being simple in structure and low in cost, occupying small land area, having strong fermenting power and large pressure, and being safe and reliable to operate, and is applicable to being built in a household, a large farm, a school, a factory and the like.

Description

technical field [0001] The invention relates to a biogas digester, in particular to a new domestic biogas digester which automatically circulates and operates efficiently under high pressure. Background technique [0002] In today's society where resources, population, and the environment are facing increasing pressure, the vigorous development of biogas digesters and anaerobic ponds, in addition to producing clean energy, the use of renewable energy has practical significance for environmental protection and ecological construction. It is a hot technology and industry concerned by today's society. However, there are various defects in the large-scale biogas digesters and anaerobic ponds in operation today, especially large-scale biogas digesters. Most of the traditional biogas digesters use arched turtle back covers. And when the gas production is large, it is very easy to make the turtle back cover burst, and when a large amount of material is fed, the bottom of the pool ...

Problems solved by technology

However, there are various defects in the large-scale biogas digesters and anaerobic ponds in operation today, especially large-scale biogas digesters. Most of the traditional biogas digesters use arched turtle back covers. And when the gas production is large, it is very easy to make the turtle back cover burst, and when a large amount of material is fed, the bottom of the pool is deposited, the bacteria, and the distribution of raw materials are uneven, the pool is large, difficult to build, small gas production, sediment, and troublesome management
