  • Fluidized bed apparatus including double chamber cartridge filter system
    Patent number: 5251384
    Abstract: A fluidized bed apparatus having a downwardly opening filter housing and including multiple processing gas outlets and a partition structure dividing the interior of the filter housing into individual downwardly-opening open-bottom compartments equal in number to the gas outlets. The partition structure extends into an expansion chamber below the filter housing. The partition structure that divides the housing not only extends the full height of the filter housing portion, but projects appreciably downwardly therefrom into the upper portion of the expansion chamber disposed below the filter housing. Each gas outlet is associated with a filter cartridge mounted on a tubular fitting. The gas filter cartridge is tubular and filters the gas passing through each of the divided filter housing compartments.
