Description

Technical Field

[0001] The invention relates to the field of biogas purification and filtration, and in particular to a filtering device for purifying biogas in an animal excrement biogas pool. Background Art

[0002] An animal manure biogas digester is a facility that converts animal manure into biogas through anaerobic fermentation. The principle is that anaerobic microorganisms decompose organic matter under anaerobic conditions to produce methane gas. This process can not only effectively treat and reduce the pollution of animal manure, but also collect the generated biogas for use as clean energy.

[0003] The biogas produced by animal manure biogas digesters contains methane and other impurities. In order to improve the quality of biogas and make it more suitable for use as energy, it is usually necessary to purify and filter the biogas. Some existing devices use filter membranes to treat the biogas when purifying and filtering the biogas. When in use, the biogas passes through the filter membrane, and the filter membrane filters the impurities in the biogas. However, the biogas passes through the filter membrane at a slow speed, which reduces the filtration efficiency of the biogas. Since the filter membrane is used too many times, a large amount of impurities will accumulate on it. At this time, it needs to be cleaned or replaced. However, some existing devices clean the filter membrane manually, which is more troublesome and reduces the practicality of the device. At the same time, when replacing the filter membrane, some of them fix it on the device by turning multiple screws, which is more troublesome. Summary of the invention
