Method and apparatus for separating solids from a solids-gas mixture

摘要

Apparatus and method for degasifying a gas and solids containing flowable material includes an inlet for the flowable material and an outlet for gas separated from the flowable material. A fluidizing rotor has radially extending open blades and is disposed for driven rotation about its center for generating a degasifying centrifugal force and has a substantially disk-shaped radially extending back plate, the back plate has a front side and a rear side, a plurality of air passages defined in and through the back plate and through which gas separated from the flowable material travels from the front side to the rear side of the back plate for discharge through the outlet. The passages extend from the front to the rear side of the back plate in a direction angled radially inwardly in the direction of flow and toward the center of the rotor and counter to the centrifugal forces generated by the rotating rotor, and the outlet is located behind the back plate and in fluid communication with the air passages to permit the separated air to travel therethrough.
