Abstract
The instant invention achieves uniformity of spills of granular material from fluid-entry faces of a panel bed by fixing the bed's position in space, and providing a constant push in a vertical direction on a deflector (preferably downward), the deflector moving in contact with the panel bed's fluid-exit wall when the bed is employed for filtration or countercurrent contacting. The constancy of the push causes the deflector's motion to occur at a constant combination of speed and displacement of the fluid-exit wall toward the fluid-entry faces of the panel bed, the combination causing a body movement of the granular material toward the fluid-entry faces, thereby causing spills of granular material to occur from the faces, renewing the faces. The constancy of the combination in the deflector's motion guarantees that the spills are uniform.
