The apparatus of the present invention is a gas distributor system for installation beneath a fluidized bed, said distributor system containing a sift trap chamber for accumulating solids filtering through the distributor plate gas inlet means. The apparatus contains no internal parts in direct contact with the fluidized bed, and thereby limits erosion of the distributor thus reducing greatly the cost of fabrication and maintenance.

An apparatus for distributing fluidization gas to a fluidized bed chamber within a fluidizing vessel, the apparatus comprising: (a) an understructure having a plurality of holes for the passage of fluidization gas; (b) a partition having a plurality of apertures for the passage of fluidization gas and in contact with the fluidized bed chamber, the gas being distributed evenly thereto, said partition being supported above the understructure and forming therebetween an intermediate chamber; (c) one or more cover means to cover each hole in the understructure, which cover means are attached to the understructure within the intermediate chamber each cover means covering one or more holes in the understructure, said cover means containing openings proximate to or along the edges thereof so that fluidization gas flowing through the holes is diverted by the cover means through the openings contained therein to the intermediate chamber before entering the fluidized bed chamber via the apertures in the partition while solids filtering through the apertures in the partition when gas flow is stopped are prevented from filtering through the void spaces in the understructure by the cover means, the solids accumulating in the intermediate chamber and returning to the fluidized bed chamber upon resumption of fluidization gas flow; (d) means for attaching the cover means to the understructure, and (e) means for supporting the partition above the understructure.
