  • Patent number: 8747503
    Abstract: The present invention relates to a separator and more specifically, but not exclusively, to a centrifugal separator for the cleaning of a gaseous fluid. A centrifugal separator is provided as comprising a housing defining an inner space, and a rotor assembly for imparting a rotary motion onto a mixture of substances to be separated. The rotor assembly is located in said inner space and is rotatable about an axis relative to the housing. The rotor assembly comprises an inlet for receiving said mixture of substances, an outlet from which said substances are ejected from the rotor assembly during use, and a flow path for providing fluid communication between the inlet and outlet, wherein the outlet is positioned more radially outward from said axis than the inlet.

  • Patent number: 8147581
    Abstract: A separation housing houses a rotor with multiple suspension chambers. Each chamber has a radially extending web portion between two rotating discs. An orifice is provided through the radially extending web portion. Another web portion urges gas radially out of the rotor. Passages through the rotating disks permit entry of gas and solid particle mixtures into the suspension chambers at high speed traveling toward each other in a suspension adjacent to the orifice. The web portion that urges gas out of the chamber pulls gas away from the suspension zone. Gas moving through the aperture and into a clean gas chamber pulls gas in the opposite direction. The result is gas in the suspension zone being fixed relative to the rotor or changing direction. Centrifugal force moves solid particles radially out of the chamber.

  • Patent number: 7927395
    Abstract: The invention relates to a centrifugal separator for cleaning of gas from solid or liquid particles suspended therein which are of greater density than the gas. A main object of the present invention is to accomplish a centrifugal separator which does not have said inactive regions and thereby achieves efficient separation of particulate contaminants from a gas. This object is achieved by the centrifugal separator initially defined, which is characterised in that the interspaces between the separation discs at least at their radially outer parts are substantially open for flow of the gas in the circumferential direction and that mutually adjacent separation discs are arranged at mutual spacing such that rotation of the rotor causes a pumping action in the interspaces, which pumping action drives the gas from the gas inlet, through the interspaces between the separation discs and out via the gas outlet.

  • Patent number: 7445653
    Abstract: A centrifugal oil separator which includes a disk separator disposed in a housing and has a plurality of spaced disks between which paths of flow for a gas to be cleaned are provided. The paths of flow connect an intake space located at the radial exterior of the disk separator with an inner, axial discharge channel. The intake space is supplied with pressurized gas via a rotation element that is configured as a compressor wheel and that is disposed in the area of an axial end face of the disk separator.

  • Patent number: 5728186
    Abstract: Fluid gases are stripped clean of gaseous and particulate pollutants as they pass rapidly up the stack of an industrial or electric power generation plant by a battery of rapidly rotated air foil spokes arrayed in two sets interleaved and revolving around a common central axis, a single motor providing the power that maintains the cleaning operation as long as flue gas flows toward discharge to the atmosphere.

  • Patent number: 5693125
    Abstract: An improved liquid/gas separator is disclosed for separating liquid and gas from a mixture that is mostly gas, within a zero gravity or variable gravity working environment. The separator includes a main housing that defines a pre-swirl chamber for receiving a liquid/gas mixture and an adjacent cylindrical separator chamber for containing liquid and gas separated from the mixture. A main shaft is rotationally secured along an interior longitudinal axis of the main housing and includes a hub portion defining exhaust slots in fluid communication with an exhaust duct within the hub for passing gas out of the separator chamber. A plurality of apertured coalescing disks are secured to the hub portion of the main shaft within the separator chamber for rotationally impacting liquid droplets and directing any droplets, bubbles or sheets of liquid formed on the disks away from the shaft toward and into a rotating liquid ring formed adjacent an interior circumference of the separator chamber.
