Dual body drum for rotary separators
First Claim
1. An apparatus for separating a fluid, comprising:
- a shaft rotatable about a central axis;
a rotary separator drum coupled to the shaft and configured to rotate therewith, the rotary separator drum comprising;
an inner drum member having inner and outer circumferential surfaces and being disposed about the shaft such that a first flow passage is defined between the inner circumferential surface of the inner drum member and the shaft, the inner circumferential surface of the inner drum member being configured to separate liquids from a fluid flow contacting the inner circumferential surface of the inner drum member; and
an outer drum member having inner and outer circumferential surfaces and being disposed about the inner drum member such that a second flow passage is defined between the inner circumferential surface of the outer drum member and the other circumferential surface of the inner drum member, the second flow passage being coaxial with the first flow passage, the inner circumferential surface of the outer drum member being configured to separate liquids from a fluid flow contacting the outer circumferential surface of the other drum member; and
a static member in fluid communication with the rotary separator drum, the static member including a separation surface located upstream from the rotary separator drum and extending circumferentially about and spaced radially outward from the outer drum member.

Abstract
A drum is for a rotary separator including a shaft rotatable about a central axis. The drum includes an inner drum member having inner and outer circumferential surfaces and being disposed generally about the shaft such that a first flow passage is generally defined between the inner drum member inner surface and the shaft. The inner drum inner surface is configured to separate liquids from a fluid flow contacting the surface. An outer drum member has inner and outer circumferential surfaces and is disposed generally about the inner drum member such that a second flow passage is generally defined between the outer drum member inner surface and the inner drum member outer surface, the second flow passage being generally coaxial with the first flow passage. Further, the outer drum inner surface is also configured to separate liquids from a fluid flow contacting the surface.

20. A separator, comprising:
-
a shaft rotatable about a central axis; a rotary separator drum coupled to the shaft and configured to rotate therewith, the rotary separator comprising; an inner drum member including a tubular body having inner and outer circumferential surfaces and an inlet, the tubular body of the inner drum member being disposed about the shaft such that a first flow passage is defined between the inner circumferential surface of the inner drum member and the shaft, the inner circumferential surface of the inner drum member being configured to separate liquids from a fluid flow contacting the inner circumferential surface of the inner drum member; and an outer drum member including a tubular body having inner and outer circumferential surfaces and an inlet, the tubular body of the outer drum member being disposed about the inner drum member such that a second flow passage is defined between the inner circumferential surface of the outer drum member and the outer circumferential surface of the inner drum member and the inlet of the outer member being disposed circumferentially about the inlet of the inner drum member, the second flow passage being coaxial with the first flow passage, the inner circumferential surface of the outer drum member being configured to separate liquids from a fluid flow contacting the inner circumferential surface of the other drum member, wherein the first flow passage receives a first portion of fluid flow entering the rotary separator drum and the second flow passage receives a second, remainder portion of the fluid flow; and a static member in fluid communication with the rotary separator drum, the static member including a separation surface located upstream from the rotary separator drum and extending circumferentially about and spaced radially outward from the outer drum member.
