Abstract:
1. A gas and solid particle mixture separator comprising: a frame; a separator housing attached to the frame; a hopper secured to a lower portion of the separator housing; a valve assembly attached to the hopper for closing the hopper and for opening the hopper to discharge solid particles received in the hopper; a rotor support shaft journaled on the frame and extending into the separator housing; an inlet passage for directing gas and solid particles into the separator housing; a rotor hub mounted on the rotor support shaft inside the separator housing, with an outer edge, a web fixed to the first disk and extending from the first disk, a second disk, with an outer edge, attached to the web fixed to the first disk; at least two suspension chambers formed by the web between the first disk and the second disk each of which includes a radially extending portion which extends from the cylindrical outer edge of the first disk and the outer edge of the second disk toward an axis of rotation, an orifice through the radially extending portion and providing a flow path for gas passage from the suspension chamber, a second web portion normal to an inner end of the radially extending portion and extending away from the radially extending portion, a fourth web portion of the suspension chamber wall that extends from the outer edges of the first disk and the second disk toward the radially extending portion at an angle that results in forcing gas through a radially facing open side of the suspension chamber, a web portion that extends from the second web portion to the fourth web portion; an arc portion of the web extending from each fourth web portion of one suspension chamber to the radially extending portion of an adjacent suspension chamber; a passage through the first disk and into the suspension chamber and adjacent to the orifice and a flap adjacent to the passage that extends inward from the first wall and toward the orifice at an angle; a passage through the second disk and into the suspension chamber and adjacent to the orifice and a flap adjacent to the passage that extends inward from the second wall and toward the orifice at an angle; wherein gas passing through the first disk makes a ninety degree change in direction, gas passing through the second disk makes a ninety degree change in direction and intersects the gas passing through the first disk moving in the opposite direction, the combined gas flow makes another change in direction of ninety degrees and moves in the direction of movement of the orifice and through the orifice and into a clean gas chamber and centrifugal force moves solid particles out of the suspension chamber; and a clean gas discharge pipe from the separator housing.
