Patent ID: 7320718

Claim:
A device for an axial cyclone of the kind which is used for separating a fluid from a gas, where the gas, during the flow through the axial cyclone, primarily in the axial direction of the axial cyclone, assigns a rotation around the center axis of the axial cyclone and where the axial cyclone in the direction of flow comprises an inlet pipe, a transitional part with a rotational element, and a downstream pipe, the cross-sectional area of the downstream pipe is smaller than the cross-sectional area of the inlet pipe, wherein said rotational element comprises axial vanes projecting from a substantially common center joint that corresponds with the center axis, said axial vanes projecting primarily radially outward in the direction of the internal surface of the axial cyclone, wherein said rotational element has a configuration that substantially avoids reduction of the cross-sectional flow area of said axial cyclone.
