Internal water-seal type methane case

Abstract

An internal water-seal type methane case is composed of a methane case body and a case cover. The methane case is characterized in that the methane case body is composed of a base, inner walls and outer walls. Inter-layers are arranged between the inner walls and the outer walls. Seal water is filled in the inter-layers. The methane case cover is composed of a top cove and vertical walls. A methane guide hole is arranged in the top cover and connected with a methane guide pipe. Transverse exhaust holes are arranged on the lower portions of the vertical walls. The methane case cover is covered in the inter-layers of the case body through the vertical walls. Not only the methane case can be used alone, but also a plurality of the methane cases can be connected in series through the methane guide pipe to be used, and the material adding time is staggered, so that methane generating peak and trough periods are complementary.

Description

Technical field: [0001] The invention relates to the technical field of biogas production and utilization, in particular to an inner water-sealed biogas tank. Background technique: [0002] The country has invested huge sums of money in the promotion of biogas for decades, but with little success. The reason is that the design of biogas digesters is unreasonable. It takes half a month for certified professionals to build a biogas digester. It is more than two meters deep underground and sealed for many years. Not only does it take a long time to build the digester, but it also requires a large investment. It is difficult to repair water and gas leaks, and it cannot be moved. More importantly, it is difficult to remove slag, the crop straw cannot be used, and the gas production is low. Now the family population is small, and human and animal excrement is not enough, so it cannot be extended to thousands of households. At present, the annual crop straw burning in our country...

[0002] For decades in the promotion of biogas, the state has invested huge sums of money, but with little success. The reason is that the design of biogas digesters is unreasonable

It takes half a month for certified professionals to build a biogas digester. It is more than two meters deep underground and sealed for many years. Not only does it take a long time to build the digester, but it also requires a large investment, and it is difficult to repair water and gas leaks and cannot be moved.

More importantly, it is difficult to remove slag, the crop straw cannot be used, and the gas production is low

Now the family population is small, and human and animal manure is not enough, so it cannot be extended to thousands of households

At present, the burning of crop straws in our country every year causes serious air pollution, and also leads to major traffic accidents, which not only causes a huge waste of resources, but also has a huge impact on air pollution, ecological agriculture, sustainable energy in rural areas, and soil compaction.
