Static fluid separator device
First Claim
1. A fluid separator, comprising:
- a casing having an inlet port and an outlet port;
a tubular body disposed at least partially in the casing and defining an annular collection chamber therebetween, the tubular body having an inlet end fluidly coupled to the inlet port of the casing, and an outlet end fluidly coupled to the outlet port, and the tubular body defining a plurality of drainage passages in fluid communication with the annular collection chamber;
a deflector disposed at least partially in the tubular body and including a central hub and a plurality of vanes extending from the central hub toward an inner circumferential surface of the tubular body, the deflector configured to swirl a fluid such that at least a portion of a denser matter of the fluid is urged radially outward through the plurality of drainage passages and into the annular collection chamber and at least a portion of a less dense matter of the fluid is directed to the outlet end; and
a recirculation member extending from the annular collection chamber to the central hub so as to provide fluid communication therebetween, the recirculation member being oriented such that the recirculation member extends radially inward from the inner circumferential surface of the tubular body and axially toward the inlet end to meet with the central hub, the recirculation member being configured to return at least a portion of any of the less dense matter that is directed through the plurality of drainage passages to an interior of the tubular body.

Abstract
A fluid separator includes a casing and a tubular main body disposed in the casing and having a central axis, inlet and outlet ends spaced along the axis, inner and outer circumferential surfaces; and drain passage(s) extending radially between the inner and outer surfaces. A collection chamber is defined between the outer surface and the casing and the inner surface defines a central flow passage, such that liquid contacting the inner surface flows through the drain passage(s) and into the collection chamber. A deflector disposed within the flow passage includes a hub located on the central axis with a bore and a plurality of vanes extending radially between the hub and the main body inner surface. Each vane has a first channeling surface facing toward the body inlet and a second channeling surface facing away from the inlet. Recirculation members fluidly connect the collection chamber with the hub bore.

14. An apparatus for separating a fluid, comprising:
-
a first cylinder; a second cylinder concentric with the first cylinder and defining an annulus therebetween, the second cylinder having inlet and outlet ends, inner and outer circumferential surfaces, and a plurality of drainage slots extending between the inner and outer circumferential surfaces such that an interior of the second cylinder is in fluid communication with the annulus via the plurality of drainage slots; a central hub disposed at least partially in the second cylinder and having a port defined therein, the port being in fluid communication with the interior of the second cylinder; a plurality of vanes extending radially from the central hub to swirl the fluid; and a recirculation member extending from the outer circumferential surface of the second cylinder to the central hub to provide fluid communication therebetween between the outer circumferential surface and the central hub, the recirculation member being disposed at an acute angle with respect to the second cylinder, such that the recirculation member extends radially inward from the inner circumferential surface of the second cylinder and axially toward the inlet end of the second cylinder to meet the central hub. - View Dependent Claims (15, 16, 17, 18)

19. A fluid separator, comprising:
-
a casing having an inlet port and an outlet port; a tubular body disposed at least partially in the casing and defining an annular collection chamber therebetween, the tubular body having an inlet end fluidly coupled to the inlet port of the casing, and an outlet end fluidly coupled to the outlet port, and the tubular body defining first and second drainage slots, the second drainage slot being axially offset from the first drainage slot and disposed between the first drainage slot and the outlet end, the first and second drainage slots being in fluid communication with the annular collection chamber, and the second drainage slot having a width that is greater than a width of the first drainage slot; a deflector disposed at least partially in the tubular body, the deflector including a central hub and a plurality of vanes extending from the central hub toward an inner circumferential surface of the tubular body, the deflector configured to swirl a fluid such that at least a portion of a denser matter of the fluid is urged radially outward through the first and second drainage slots and into the annular collection chamber and at least a portion of a less dense matter of the fluid is directed to the outlet end, the central hub defining a port in fluid communication with an interior of the tubular body; and a recirculation member extending from the annular collection chamber to the central hub so as to provide fluid communication between the annular collection chamber and the port of the central hub, the recirculation member being configured to recycle the at least a portion of the less dense matter that is directed through the first and second drainage slots. - View Dependent Claims (20, 21, 22)
