NOVELTY - A methane generator with double feed openings comprises a tank (1), a methane guide tube (2), a flange and sealing cushion (3), a discharge tube (4), a flange and sealing cushion (5) of discharge tube, a hanging ring (8), and a support (9); where the sealing cushion (5) of discharge tube which is higher than the methane generation material (7) and the surfaces of the internal and external structures of the tank (1) and the discharge tube (4) are completely sealed by the internal and external coatings (6) of the tank.    USE - The methane generator with double feed openings is useful for producing methane.    ADVANTAGE - The generation, transport, and installation are convenient; the low-quality fuels are largely used, and the water is saved; the yield of the gas is high; the discharge is convenient and safe, and the labor is saved; it can be putted in a small plastic shed, which is convenient for heating and insulating.    DETAILED DESCRIPTION - A methane generator with double feed openings comprises a tank (1), a methane guide tube (2), a flange and sealing cushion (3), a discharge tube (4), a flange and sealing cushion (5) of discharge tube, a hanging ring (8), and a support (9); where the tank is a sealed container tank, and its feed inlet is sealed by the rectangular flange and sealing cushion (3) containing the methane guide tube (2); the discharge tube (4) is welded on the bottom inside the tank (1), and a discharge hole of the discharge tube (4) is not corresponding to the feed inlet of the tank, an end part is sealed by the flange and sealing cushion (5) of discharge tube which is higher than the methane generation material (7); and the surfaces of the internal and external structures of the tank (1) and the discharge tube (4) are completely sealed by the internal and external coatings (6) of the tank.
