Abstract
An apparatus for uniformly, downwardly moving in a vessel a compact bed of solid particles in contact with a liquid. Within the vessel there is provided a rotatable lower disc which has a radially extending opening for the passage of solids therethrough. The lower disc carries a member adjacent the opening for directing solids through the opening during rotation of the lower disc. This member preferably extends above the lower disc. A system is provided to maintain the liquid within the vessel while the solid particles pass out of the bottom portion of the vessel. A rotatable upper disc having a radially extending opening may be present to distribute solids charged to the vessel onto the upper surface of the bed of solid particles.
