Abstract
The invention is directed to a bubble cap including: a riser having a lower end located within and extending through an aperture in the plate of the distribution apparatus and a top end to define a passageway between the ends; a cap located over the top end of the riser, the cap having a top portion and a downwardly extending skirt portion; at least one spacer located between the riser and the cap to maintain a gap between the top end of the riser and the cap; and a plurality of riser vanes located between the top end of the riser and the top portion of the cap. An annulus (“bubble cap annulus”) is created between the riser and the cap. The riser vanes are preferably flush against the underside of the bubble cap top wall. The riser vanes are spaced from each other to form vane passageways. Preferably, the vane passageways are the only (or sole) means of fluid communication between the bubble cap annulus and the riser passageway.
