    Abstract: There is provided an improved panel-bed method and apparatus for achieving an intimate contact of a gas and a loose granular solid material (e.g., for filtering dust from the gas). A bed of the material is housed in a tall, narrow panel, across which gas moves in a substantially horizontal direction. Gas-entry portions of the granular bed are supported by louvers that slope inwardly and upwardly from nearby their outer edges. The total area of the gas-entry faces presented by these gas-entry portions is greater than the projected vertical frontal area of the panel. After an interval of the contact, gas-entry faces of the granular material are renewed by causing en masse displacement of the material respecting the supporting louvers, the displacement producing a spill of a surface layer from each gas-entry face. This displacement is preferably accomplished by causing louvers to move sharply upward (e.g., as may be caused by an upward blow of a hammer).

Collection of the filtrate substance within the pores of the particles rather than within the interstices of the bed enhances the filtering capacity and does not impede the flow of fluid through the bed of particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction, detergent washing, and centrifugal separation, yet retain their desired properties.

  • Patent number: 5198002
    Abstract: A gas cleaning filter is formed in-situ within a vessel containing a fluidizable bed of granular material of a relatively large size fraction. A filter membrane provided by a porous metal or ceramic body or such a body supported a perforated screen on one side thereof is coated in-situ with a layer of the granular material from the fluidized bed by serially passing a bed-fluidizing gas stream through the bed of granular material and the membrane. The layer of granular material provides the filtering medium for the combined membrane-granular layer filter. The filter is not blinded by the granular material and provides for the removal of virtually all of the particulates from a process gas stream. The granular material can be at least partially provided by a material capable of chemically reacting with and removing sulfur compounds from the process gas stream.

  • Patent number: 5165900
    Abstract: Gas/solids contact apparatus includes a tower-like, vertical vessel divided by internal wall structures into three axially-extending, concentric spaces. An inner space, typically of generally circular cross section and extending along the axis of the vessel, receives the gas which is to be contacted with particulate solids. An intermediate space, which may have a variety of configurations, surrounds the inner space and, during operation the contactor, contains a downwardly moving bed of solids. An outer space, typically of annular configuration, surrounds the intermediate space and serves to collect gas which flows from the inner space, generally horizontally through the moving bed of solids and then into the outer space for discharge through a gas outlet. In a preferred embodiment the moving bed of solids is contained by louvered walls, and these walls are constructed as modules which can be arranged to provide contactors having different gas and solids handling capacities.

  • Patent number: 5160513
    Abstract: An inlet distributor for use in downflow reactors or contacting vessels removes debris from the feedstream that could otherwise plug the top of the catalyst or particle bed surface. Gaseous streams are charged into the inlet distributor and debris is separated from the inlet stream and accumulated in the bottom of the distributor. Fluid flow in the bottom of the distributor is minimized to prevent reentrainment of debris into the gas stream as it leaves the distributor.

  • Patent number: 5130106
    Abstract: Void blowing by gas flow through a bed of particulate material is avoided by the use of a cover plate that eliminates void spaces at the top of the bed and a vertical duct that allows a head of particulate material to be maintained above the cover plate. The particle bed is arranged in the usual fashion using inner and outer screens to hold particulate material in a vertically extended bed into which particulate material is intermittently added and withdrawn. The top of the particulate bed is contacted by an imperforate cover plate that is sloped up to an inlet opening that has a smaller cross-sectional area than the area of the bed. The cover plate has a slope which is greater than the angle of the repose of the particles so that particles filling the top section of the bed will be free of void spaces.

  • Patent number: 4967688
    Abstract: A powder processing apparatus of the fluidized bed type wherein air is blown into a cylindrical container through its bottom to perform various treatments while keeping powder in the container in fluidized condition. Air fed in through an opening in the bottom surface of the container is introduced into a rotating hollow frusto-conical body and is allowed to blow out in the centrifugal direction from an air diffusion clearance defined between the skirt end of the frusto-concial body and the bottom surface of the container, thereby forming a fluidized bed of powder. The portion of the bottom surface around the opening rises and/or a member made of air-permeable material is installed in the opening in the bottom surface to prevent passage of powder; this arrangement, coupled with the air current blowing out of the air diffusion clearance, prevents entry and hence flow-out of powder.
