Automatic deslagging and stirring methane tank

Abstract

The invention discloses an automatic deslagging and stirring methane tank comprising a fermentation tank, a feed pipe and a deslagging chamber, wherein the fermentation tank is communicated with the deslagging chamber through a discharge pipe, and the discharge opening of the discharge pipe is higher than the bottom part of the deslagging chamber; the deslagging chamber is communicated with a liquid storage pool through an overflow pipe, and the height of the inflow inlet of the overflow pipe is equal to the height of the discharge opening of the discharge pipe; the liquid storage pool is communicated to a liquid outlet on the pipe wall of the feed pipe through a liquid return pipe, the horizontal height of the liquid inlet of the liquid return pipe is higher than the horizontal height of the liquid outlet, and an airtight one-way valve is arranged at the liquid outlet. In the automatic deslagging process of the fermentation tank, the methane tank disclosed by the invention can separate out a certain amount of water, the water is collected and flows back into the fermentation tank, since the feed pipe and the discharge pipe are located in two opposite directions, circular reflux is formed in the whole methane tank system to promote raw materials in the methane tank to be continuously stirred so as to facilitate the full fermentation of the raw materials in the methane tank and facilitate the generated biogas to ascend to a gas storage chamber at the upper part of the fermentation tank.

Description

technical field [0001] The invention relates to a biogas digester, in particular to a biogas digester with automatic slag discharge and stirring. Background technique [0002] Now, with the popularization of various types of biogas digesters in rural areas, the utilization rate of rural bioenergy has been improved, the living environment in rural areas has been improved, and the joint development of livestock, poultry, fish husbandry and planting has been promoted, forming a green circular economy model. Put various raw materials, water and fermentation bacteria into the biogas digester, seal it and start to use. Through the action of microorganisms, the raw materials are fermented to produce combustible biogas, which is used as clean energy for users. Biogas digesters need regular slag discharge. Generally, after 1-2 years of use, the gas production space becomes smaller due to slag fullness. People usually use slag extractors to extract slag, but it is often not easy to co...

Problems solved by technology

[0003] In particular, after the biogas digester is in operation, scum will form on the surface of the raw material liquid. Over time, the scum will crust, and a hard crust will form on the surface of the liquid, which will affect the fermentation process, reduce the biogas production, and hinder the formation of biogas Rising from the raw material to the air storage chamber above the fermentation tank

Therefore, it is necessary to stir the liquid in the biogas tank regularly. The existing technology is to install an electric stirring device in the fermentation tank. This device increases the investment in technology and cost, which is not conducive to popularization in rural areas.
