  • Patent number: 8404033
    Abstract: A gas scrubber is presented. The gas scrubber comprises a nozzle that atomizes a liquid to form droplets. The droplets are preferably expelled from the nozzle in substantially a hollow cone spray pattern with a velocity of at least 4000 feet per minute. A stream of gas containing particulates that requires scrubbing interacts with the droplets. After the interaction, the gas-droplet combination impinges on a target. Preferred targets include droplets from a second nozzle, a ducting surface, or a throated passage.
    Type: Grant
    Filed: February 5, 2008
    Date of Patent: March 26, 2013
    Inventors: Richard S. Crews, John S. Crews
  • Patent number: 7959721
    Abstract: A modular scrubbing system is presented. The scrubber system comprises multiple modules that allow a gas flow to turn-around return back through scrubbing modules. Contemplated modules include inlets, outlets, turn-arounds, and scrubbing modules.

  • Patent number: 5915814
    Abstract: An improved cyclone dryer is disclosed, having an outer cylinder, an inner cylinder, and a cone-shaped chamber. The outer cylinder has a tangential airstream orifice for injecting a high-speed stream of material and air, or other gases, into the dryer. The inner cylinder has a plurality of apertures and a plurality of deflectors that deflect air and material into a cavity defined by the inner cylinder and the cone-shaped chamber. The cone-shaped chamber, the outer cylinder, and the inner cylinder define an annular air chamber. An exhaust assembly is attached proximate the inner and outer cylinders, and is in fluid communication with the cavity.

  • Patent number: 5791066
    Abstract: An improved cyclone dryer is disclosed, having an upper, a lower cylinder and a cone-shaped chamber that define a cavity. The improved dryer is adapted for a high-speed airstream to enter the cavity via a tangential airstream orifice. Wet material is fed into the improved dryer via an input assembly that is mounted proximate an exhaust assembly and feeds wet material into the cavity, at a point proximate a lower portion of the cylinder and proximate the cone-shaped chamber.
