Technical field

The utility model relates to the technical field of biogas treatment devices, specifically a gas-liquid separation device.

Background technique

Biogas is a combustible gas produced by microbial fermentation of organic matter under anaerobic conditions. Because this gas was first discovered in swamps, it is called biogas. Various organic matter such as human and animal manure, straw, sewage, etc. are fermented under anaerobic (without oxygen) conditions in a closed biogas tank, that is, they are decomposed and transformed by a wide variety of biogas fermentation microorganisms, thereby producing biogas. Biogas is a mixture of various gases, which contains more than 55% methane, about 30% carbon dioxide, and a small amount of ammonia, hydrogen sulfide, etc. Its characteristics are similar to natural gas. For example, the air contains 8.6%-20.8% (by volume) When the amount of biogas is measured), an explosive mixed gas will be formed. 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 methanol, formalin, Carbon tetrachloride and other chemical raw materials. There are generally four methods for biogas purification, namely absorption method, pressure swing adsorption method, low-temperature condensation method and membrane separation method.
