Radial vane pack for rotary separators
First Claim
1. An apparatus for separating a fluid, comprising:
- an inner drum wall disposed around and coupled to a shaft;
an outer drum wall disposed around the inner drum wall, the outer drum wall being configured to rotate to separate a higher-density component of the fluid from a lower-density component of the fluid;
a first radial vane disposed between the inner drum wall and the outer drum wall and having first contours configured to turn the fluid in at least one of a radially-inward direction and a radially-outward direction; and
a housing at least partially surrounding the outer drum wall and configured to receive the high-density component of the fluid therefrom.

Abstract
Apparatus and methods for separating a fluid, with the apparatus including an inner drum wall disposed around and coupled to a shaft. The apparatus also includes an outer drum wall disposed around the inner drum wall, the outer drum wall being configured to rotate to separate a higher-density component of the fluid from a lower-density component of the fluid. The apparatus further includes a first radial vane disposed between the inner drum wall and the outer drum wall and having first contours configured to turn the fluid in at least one of a radially-inward direction and a radially-outward direction. The apparatus also includes a housing at least partially surrounding the outer drum wall and configured to receive the high-density component of the fluid therefrom.

13. A method for separating a fluid, comprising:
-
introducing a fluid to flow passages defined in a rotatable drum, one of the flow passages being an inter-vane flow passage defined between first and second radial vanes disposed in the rotatable drum; turning the fluid in the inter-vane flow passage in a radially-inward direction using the first and second radial vanes, to partially separate a higher-density component of the fluid from a lower-density component thereof; turning the fluid in the inter-vane flow passage in a radially-outward direction using the first and second radial vanes, to separate the higher-density component from the lower-density component; and rotating the rotatable drum to urge the high-density component toward a housing disposed around the rotatable drum. - View Dependent Claims (14, 15, 16, 17)

18. A fluid separator, comprising:
-
a rotatable drum including inner and outer drum walls, the inner drum wall coupled to a shaft, the rotatable drum configured to receive a fluid at an upstream end, and to discharge the fluid at a downstream end and to rotate to separate a liquid from the fluid; a radial vane pack disposed between the inner and outer drum walls and comprising radial vanes extending from proximal the upstream end to proximal the downstream end, each of the radial vanes having contours configured to turn the fluid at least one of 30 degrees in a radially-inward direction and 30 degrees in a radially-outward direction, and each of the radial vanes defining at least one drainage port extending radially therethrough; struts extending at least partially between the inner and outer drum walls, each of the struts coupled to at least one of the radial vanes and defining a drainage duct in fluid communication with at least one of the drainage ports; and a housing at least partially surrounding the outer drum wall and being configured to receive the liquid separated by the drum. - View Dependent Claims (19, 20)
