Large-scale biogas system

Abstract

The invention discloses a large-scale biogas system which is characterized by comprising a water collection-desilting tank, a regulating tank, an anaerobic digestion tank, a dish gas holder, a biogas slurry storage tank, a biogas residue stacking site, a solid-liquid separation machine room, a management room, a boiler room, a road structure, a flood carrier and an in-station combination drainage ditch, wherein the water collection-desilting tank communicates with the regulating tank through a pipeline; the solid-liquid separation machine room and biogas residue stacking site are arranged side by side; the dish gas holder communicates with the boiler room; and the boiler room is connected with a heat exchange tube in the anaerobic digestion tank through a pipeline. The large-scale biogas system is simple in structure, and is suitable to be used as a large-scale biogas system. The large-scale biogas system greatly lowers the construction cost and use cost, has the advantages of reasonable systematic distribution, simple overall structure and high efficiency, and is easy to construct and implement.

Description

technical field [0001] The invention relates to the biogas field, in particular to a large-scale biogas system. Background technique [0002] As a clean new energy source, biogas has been widely used more and more. The proof is that because biogas is a high-quality, efficient, green and environmentally friendly fuel, the prospect of replacing traditional energy is very broad. In addition to being directly burned for cooking, drying agricultural and sideline products, heating, lighting, and gas welding, biogas can also be used as fuel for internal combustion engines and for the production of chemical raw materials such as methanol, formalin, and carbon tetrachloride. The feed liquid and sediment discharged from the biogas plant after fermentation contain rich nutrients and can be used as fertilizer and feed. However, after investigation, it was found that due to the unreasonable design of the existing biogas system, it could not be implemented on a large scale, which hinder...
