Abstract

The invention discloses a side-arranged biogas slurry external-circulation rotational-flow stirring biogas pool including a pool wall (1), a pool bottom (2), a top gas collecting hood (3) and two groups of external-circulation pipelines; the pool bottom (2) and the top gas collecting hood (3) are connected through the pool wall (1); two groups of external-circulation pipelines are respectively located at two opposite side faces of the pool wall (1), and each group of external-circulation pipeline comprises a horizontal pipeline (4) and an elbow pipe (5), each horizontal pipeline (4) is connected with the side face of the pool wall (1) and is located at the upper end of the side face of the pool wall (1), and each elbow pipe (5) is located at the lower end of the side face of the pool wall (1) and is connected with the side face of the pool wall (1); a circulation pump is connected with each horizontal pipeline (4) and each elbow pipe (5); a circulation pump protecting hood (6) is located outside each circulation pump. The biogas pool has the advantages of being simple in structure of the pool body, convenient to install, convenient to transport, suitable for rural areas, and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of biomass energy biogas, and in particular relates to a side-mounted biogas slurry external circulation swirl stirring biogas digester. Background technique [0002] In the process of biogas production by anaerobic fermentation, stirring can promote the release of biogas, increase the chance of contact between microorganisms and organic matter, thereby increasing gas production and promoting mass transfer. In the past, many small biogas digesters did not use stirring devices: such as the Chinese patent "biogas digester" (application publication number CN 103525692 A, application publication date 2014.01.22), the Chinese patent "a biogas digester" (application publication number CN 102864071 A, application Announcement date 2013.01.09), a small number of biogas digesters using stirring equipment have not carried out scientific analysis of the stirring flow field in the biogas digester, and the formulation of...
