Efficient two-phase anaerobic fermentation device

The invention discloses an efficient two-phase anaerobic fermentation device. The efficient two-phase anaerobic fermentation device comprises a hydrolysis acid production reactor, a high-temperature hydrolysis device and at least one methanogenesis reactor, wherein a bottom percolate storage chamber of the hydrolysis acid production reactor is connected with the bottom of the methanogenesis reactor; the lower part of the hydrolysis acid production reactor is provided with a cavity stainless cone-shaped bracket with holes; the bottom of the cone-shaped bracket is connected with the high-temperature hydrolysis device; the methanogenesis reactor is provided with an upper discharge hole and a lower discharge hole; the upper discharge hole and a feed inlet form a self-circulation pipeline; the lower discharge hole of the hydrolysis acid production reactor is connected with a rotary sprayer; the high-temperature hydrolysis device is used for receiving large particle solid separated by the cone-shaped bracket; and solid-liquid separation is carried out by a biogas residue press filter at the outlet. The device is simple in manufacturing procedure, reasonable in structure, easy in maintenance, high in fermentation efficiency and stable and reliable in performance, is suitable for anaerobic digestion of organic wastes, and meets the large-scale production requirement.
