  • Patent number: 7875092
    Abstract: Axial flow demisting cyclone for separation of material compositions of gas, liquid and particulate solids comprising an inlet conduit (18) for the material composition and an outlet conduit (19) for the substantially dry and clean gas, and a swirl facilitating device (20) that sets the entering material composition in rotation. The cyclons comprises a mainly cylindrical tube (11) which is provided with slots or perforations (21) to allow parts of the material composition, hereunder liquids and particulate solids to flow out from the cyclone tube (11) and into a substantially closed chamber (22) which is delimited by an inlet plate (24), by an outlet plate (23) ad by a circumferential plate (12).

  • Patent number: 7459001
    Abstract: Vane diffuser for use in separators for separating a liquid phase and/or a particulate material from a gas flow, includes a distribution chamber that communicates with the inlet pipe stub of the separator. A top plate, a bottom plate, and a plurality of curved, parallel vanes together delimit a plurality of diffuser channels. Each of the vanes has a thickness which varies in the flow direction to ensure an even expansion of the cross-sectional area of the diffuser channels, thereby reducing reverse flow along the suction side of the vanes, as occurs with vanes of uniform thickness.
