Abstract
An apparatus for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with apertures disposed within the partitions. The apertures are covered by shrouds that extend above the edges of the apertures to prevent solid particles from spilling through inlet apertures.
Claims5
An apparatus for supporting a granular solid in a cross-flow system comprising:
- an inlet partition having apertures, wherein each aperture has a generally V-shaped lower edge and an upper edge;
- an outlet partition having apertures, wherein each aperture has a lower edge and an upper edge, and wherein the inlet partition and the outlet partition are spaced to define a particle retention volume for holding a granular solid;
- and
- a plurality of inlet blisters, each having an upper edge and a lower edge, each lower edge having a generally V-shape, and each inlet blister lower edge affixed to the lower edge of the inlet aperture, where the inlet blister upper edge extends to at least the upper edge of the inlet aperture and wherein the uppermost inlet blisters extend away from the particle retention volume space at an angle from vertical of about 1 degree to about 20 degrees, the remaining inlet blisters extend away from the particle retention volume space at an angle from vertical of about 10 degree to about 30 degrees and the uppermost inlet blisters extend away from the vertical at a steeper angle than the remaining inlet blisters.
