Problems solved by technology

However, these large-scale biogas digesters are far away from the villagers' residential areas, usually more than 2 kilometers away, and the cost of pipelines is high. As a result, most of the generated biogas is emptied, which not only pollutes the air, but also wastes energy.

Abstract

The invention relates to a method for conveying biogas at a long distance and low cost. The method is characterized in that a large biogas digester with the biogas output pressure p is networked withthe periphery of the large biogas digester as much as possible, especially a biogas digester and a septic tank which are scrapped at the user end of the biogas pipeline at a long distance, and a gas cabinet with the biogas height of no more than h = P/rho g -0.3m is built at the position h = p/rho g m near the liquid surface of the pond near the user end of the biogas pipeline for long-distance transportation. The device for conveying biogas at a long distance and low cost comprises a biogas digester, a septic tank, a water pond and a gas collecting hood, wherein the biogas digester, the septic tank and the gas collecting hood are connected with the large biogas digester through a connecting pipeline, and the connecting pipeline is provided with a branch pipe for conveying to the user. According to the method and device, only the existing waste biogas digester or the septic tank needs to be used, so that the biogas can be conveyed at a long distance and low cost, the method and deviceis safe and environment-friendly, and has economic benefits.

Description

technical field [0001] The invention belongs to the field of resource utilization and environmental protection, and in particular relates to a method and a device for long-distance and low-cost transportation of biogas. Background technique [0002] Biogas: It is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity, and pH. Because this gas was first found in swamps, lakes, and ponds, people called it biogas. Biogas is a mixed gas whose main component is methane, followed by carbon dioxide, hydrogen sulfide (H 2 S), ammonia and some other components. In the composition of biogas, combustible components include gases such as methane, hydrogen sulfide, carbon monoxide and heavy hydrocarbons; non-combustible components include gases such as carbon dioxide, nitrogen and ammonia. [0003] The state supports the development of biogas, but most of the household, joint household and me...
