Slurry-gas separation device

The utility model discloses a slurry-gas separation device which comprises a separation tank and a liquid inlet which is formed in the side surface of the upper part of the separation tank; a reinforcing plate is arranged by directly facing the liquid inlet on the inner wall of the separation tank; a plurality of quadrihedron-shaped bosses are arranged on the reinforcing plate; a support is mounted inside the separation tank; a gas guide tube is mounted on the support; a separator is arranged below the liquid inlet inside the separation tank; the separator comprises a cylindrical main body and an inverted frustum separation plate positioned below the main body; a plurality of quadrihedron-shaped bosses are arranged on the inner wall of the main body and the inner side of the separation plate; a pressure gauge hole, an exhaust hole, a liquid level control hole and a liquid discharge hole are sequentially formed in the separation tank. According to the slurry-gas separation device disclosed by the utility model, by arranging the reinforcing plate at the liquid inlet, the service life of the separation tank is prolonged, and by arranging the quadrihedron-shaped bosses on the reinforcing plate, the separation plate and a baffle plate, slurry fed in from the liquid inlet is sufficiently collided, and the gas is sufficiently separated from the liquid.
