Abstract
Abstract A reactor for reactivating solid particulate material with a fluid comprising a reaction chamber including a perforated bottom wall and upright wall means disposed on the bottom wall and defining within the reaction chamber a central whirl chamber and a first and a second annular whirl chamber surrounding the central whirl chamber. Passageways are provided in the wall means to interconnect the respective whirl chambers. A first inlet is provided to supply solid particulate material to the central whirl chamber and a second inlet communicates with the perforated bottom wall to supply a fluid therethrough to fluidize the particulate material in the central whirl chamber. The particulate material in fluidized condition is subsequently transferred to an outlet via the first and second annular whirl chambers.

Claim 7
Dependent Claim
59 words
A reactor as defined in claim 1, wherein said upright wall means includes second upright wall means concentrically surrounding said annular whirl chamber and defining within said reaction chamber a second whirl chamber, said second wall means having passage means along a portion of its circumference connecting said first mentioned annular whirl chamber with said second annular whirl chamber.
Claim 8
Dependent Claim
33 words
A reactor as defined in claim 8, wherein said outlet communicates with said second annular whirl chamber at a portion thereof circumferentially offset relative to said passage means in said second whirl chamber.
Claim 9
Dependent Claim
40 words
A reactor as defined in claim 8, wherein said second upright wall means is substantially annular, and wherein said passage means is a slot formed in said second wall means and extending axially therewith upwardly from said perforated bottom wall.
