    摘要： This invention is directed to a continuously cleanable, high performance filtration apparatus and a method for using the apparatus. The apparatus is a radial inflow centrifugal filtration device, which includes a filter element located within a chamber and rotatably coupled to a filtered fluid outlet in a bulkhead that abuts the chamber. The filter element is generally tubular, its side-walls encircling and, thus, defining an interior plenum. The filter element side-walls incorporate a filter media, preferably a laminated microporous membrane filter media. The filter element is rotatably coupled at the filtered fluid outlet by a seal which can maintain a seal as filter element rotates. Additionally, the device can include a boundary layer momentum transfer device made up of a plurality of stacked annular disks having central openings, each disk separated from adjacent disks by a desired gap. The central openings define a cavity in which the filter element is mounted.

    摘要： A filter cartridge for removing particles or dust from a stream of moving gas or air, including a filter medium disposed between a pleated inner wire support frame, outer longitudinal wire support stays disposed along each inner apex of the pleats of the filter medium, and end caps. The outer wire stays are formed from inwardly bent wires which attach at each end to the inner frame and exert pressure on the filter medium to support it against inner pressure of a pulse jet cleaning device. Preferred filter media are felt or fabric composites containing a layer of porous expanded polytetrafluoroethylene membrane. A preferred form of lower end cap has the periphery contoured to conform to the configuration of the filter medium and inner support frame. The cartridge structure is advantageous in preventing build-up of ledges of dust on protuberances, with consequent reduction of filter efficiency.
