  • Patent number: 9045072
    Abstract: A vacuum loader truck that includes a storage tank that can be loaded and unloaded with debris. The vacuum loader truck includes a debris level sensor that generates a sensing beam to detect the level of debris within the storage tank. The level of debris within the storage tank is determined by a control module and displayed. The debris level sensor may be an ultrasonic sensor that generates a sensing beam that is reflected off of the top surface of the debris within the storage tank. The control module determines the height of the debris within the storage tank based upon the time delay between the generation of the sensing signal and the reflected signal. The control system further includes a particle sensor to determine whether particles are entrained in the airflow from the storage tank. A pair of pressure sensors are located on opposite sides of an air filter to sense the differential pressure across the air filter.

    Abstract: A filtering apparatus having a plurality of passages made up of juxtaposed longitudinally extending channels. The passages are axially divided by a porous filtering media extending across the channels whereby the channels fluidly communicate through the porous filtering media. A pressure differential is created across the filtering media by restricting flow through an end of each channel, with each restriction being at an opposite end from that of the other channel. As flow restriction rather than outright blocking is used, some flow is possible along each passage directly along the channels even if the channels lose the ability to fluidly communicate through clogging of the filtering media.

  • Patent number: 8460442
    Abstract: Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter.

  • Publication number: 20130125848
    Abstract: A centrifugal separator comprises a filtered-gas passageway, a spinner, and a drive mechanism. The filtered-gas passageway has an inlet. The spinner is configured and adapted to rotate about a spinner axis relative to the filtered-gas passageway, and has an inner cavity, a gas permeable outer wall, and a plurality of protrusions that extend radially outward from the gas permeable outer wall relative to the spinner axis. The inner cavity of the spinner is operatively connected to the inlet of the filtered-gas passageway. The drive mechanism is adapted to rotate the spinner about the spinner axis at a rate such that the protrusions prevent particulates from passing through the gas permeable outer wall and into the inner cavity of the spinner and such that gaseous matter is able to pass through the gas permeable outer wall, into the inner cavity, and thereafter into the filtered-gas passageway via the inlet.

  • Publication number: 20130068097
    Abstract: An anti-clogging filter system for filtering a fluid containing large particles and small particles includes an enclosure with at least one individual elongated tubular filter element in the enclosure. The individual elongated tubular filter element has an internal passage, a closed end, an open end, and a filtering material in or on the individual elongated tubular filter element. The fluid travels through the open end of the elongated tubular element and through the internal passage and through the filtering material. An anti-clogging element is positioned on or adjacent the individual elongated tubular filter element and provides a fluid curtain that preferentially directs the larger particulates to one area of the filter material allowing the remainder of the filter material to remain more efficient.

  • Patent number: 8317905
    Abstract: Fine, solid particles in a gas stream, especially fly ash particles in the hot gas stream from a coal/coke-utilizing synthesis gas unit, are agglomerated by passage through a gas flow matrix element having a body with confined gas flow channels which bring the particles into close proximity to one another in an environment of low turbulence; a rough surface on the gas flow passages provides surface induction to promote agglomeration of the particles. The larger, agglomerated particles may then be removed from the gas stream by inertial separators such as cyclones.
