An anti-seismic automatic slag discharge biogas digester

Abstract

The invention discloses an anti-seismic full-automatic deslagging biogas tank. A deslagging chamber, a filter chamber and a hydraulic pressure chamber are sequentially arranged above the top of a fermenting tank; a first filter plate is arranged between the adjacent deslagging chamber and filter chamber, a second filter plate is arranged between the adjacent filter chamber and hydraulic pressure chamber, and the diameter of a filter hole of the first filter plate is longer than that of the filter hole of the second filter plate; the fermenting tank is internally provided with an anti-seismic beam; the anti-seismic beam comprises a main beam and auxiliary beams; and two pairs of the auxiliary beams are arranged. According to the anti-seismic full-automatic deslagging biogas tank, old biogas slag is discharged from a deslagging pipe in a biogas generating process, the discharged biogas slag enters the deslagging chamber, solid biogas slag included in the biogas slag is filtered through filter screens positioned on two side walls of the filter chamber, and a biogas slurry flows into the hydraulic pressure chamber, in such a way, and generated biogas is capable of conveniently ascending to a gas storage chamber positioned at the upper part of the fermenting tank and is 30% more than the gas output of the traditional biogas tank. The anti-seismic full-automatic deslagging biogas tank disclosed by the invention has good seismic resistance, thereby being suitable for districts such as mountain districts, geologic active districts and seismically active districts.

Description

technical field [0001] The invention relates to a biogas pit, in particular to an anti-seismic fully automatic slag discharge biogas pit. 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 complete, ...

Problems solved by technology

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 complete, and some machines are difficult to completely solve practical problems. Finally It is necessary to manually remove the slag from the pool, which poses a great hidden danger to personal safety.

[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.

[0004] At present, many biogas digesters are used in plain areas with stable geological structures. Therefore, the structure requirements of biogas digesters are simple, but they cannot adapt to areas with active geology and frequent earthquakes. Leakage, loss and safety hazard
