Abstract
Device for separating gas from a mixed flow which may contain light and heavier gas fractions, liquid and/or solid particles, which device comprises a rotor with a rotor core which tapers conically from an upstream end towards a downstream end with respect to the flow direction of the mixed gas flow through the rotor, and further comprising wings arranged on the rotor core and running in the longitudinal direction of the rotor core, the width of said wings in the radial direction of the rotor increasing in the direction of the downstream end of the rotor, and a rail supported on the free edges of the wings, arranged in a spiral path and standing on one edge, forming a rotating feed screw.
Claims8
A device for separating gas from a mixed gas flow which may contain light and heavier gas fractions, liquid, and/or solid particles, which device comprises:
- a rotor rotatably arranged in a rotor housing with a cylindrical rotor housing wall, wherein the rotor and the rotor housing have a radial and axial extension and an axis of rotation of the rotor coincides with a center axis of the rotor housing,
- a drive unit connected to the rotor and operative for rotation of the rotor;
- an inlet arranged at an upstream first end of the rotor housing for feeding an axially directed mixed gas flow into the rotor;
- a gas outlet arranged at a downstream second end of the rotor housing for discharging gas;
- and
- a return outlet arranged at the upstream first end of the rotor housing for discharging an outlet flow of separated heavier gas fractions, solid particles, and/or liquids,
- wherein the rotor comprises:
- a rotor core which tapers conically from an upstream first end towards a downstream second end of the rotor with respect to a flow direction of the mixed gas flow through the rotor;
- wings, arranged on the rotor core and running in a longitudinal direction, a width of said wings in a radial direction of the rotor increases in a direction towards the downstream second end of the rotor;
- and
- a rail supported on free edges of the wings, arranged in a spiral path and standing on one edge, forming a rotating feed screw close to the rotor housing wall with a pitch designed for feeding separated heavier gas fractions, solid particles, and liquids towards the return outlet arranged at the upstream first end of the rotor housing.
