<p>An outside hydraulic anaerobic ferment device comprises a tank body and a biogas storage cover, characterized in that there is at least a ring tank, which is structured by an inner tank-neck, an outer tank-neck and the topside of a tank-bingy, and the ring tank is on the top of the tank-bingy, and the inner tank-neck is communicated with the tank-bingy; the biogas storage cover is fixed in each outer tank-neck. The outside hydraulic anaerobic ferment device of the invention uses clean water stored in the ring tank as sealed liquid between the biogas storage cover and the tank-bingy, to prevent biogas leaking from the tank-bingy and provide a desired hydraulic operating condition. The design of the outside hydraulic anaerobic ferment device is scientific, reasonable and practicable.</p> |
