Appl. No.:

12/025939

Inventors:

Richard S. Crews - Cerritos CA, US
John S. Crews - Huntington Beach CA, US

International Classification:

B01D 47/14
B01D 47/10

US Classification:

96275, 96290, 96323

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.

Appl. No.:

8/706342

Inventors:

Richard S. Crews - Cerritos CA

Assignee:

Hydrofuser Technologies, Inc. - Newport Beach CA

International Classification:

F26B 1712

US Classification:

34168

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.

Appl. No.:

8/697827

Inventors:

Richard S. Crews - Cerritos CA

Assignee:

Hydrofuser Technologies, Inc. - Newport Beach CA

International Classification:

F26B 1712

US Classification:

34166

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.
