Oil separator

Claim 2

Apparatus for separating oil and water from an oil-water mixture, comprising: a vessel, an inlet conduit extending upwardly into said vessel, said inlet conduit having a discharge port at the terminus thereof, deflector means stationed within said vessel in juxtaposition to said discharge port, said deflector means comprising means for intercepting fluid discharged from said port including first intercepting means stationed opposite said discharge port and second intercepting means stationed opposite said first means whereby fluid directed against said first means is once reversed and directed against said second means whence said fluid is again reversed in direction, a first outlet port near the bottom of said vessel for drawing off separated water from said vessel, a second outlet port near the top of said vessel for drawing off separated oil from said vessel, and control means coupled to said outlet ports for independently controlling the rate of outflow therefrom.

Claim 3

The apparatus described in claim 1 wherein said deflector means comprises: a first disc shaped plate member having a concave surface, said concave surface being positioned in opposed relation to said discharge port, a collar mounted upon said inlet conduit surrounding said discharge port, said collar having a closed lower end and an open end, said upper end having the edge thereof spaced from and above the outer peripheral edge of said disc member.

Claim 4

The apparatus set forth in claim 1 wherein said inlet conduit is provided with length adjusting means for varying the location of said discharge port within said vessel, said deflector means being rigidly attached to said inlet conduit at points near said discharge port and spaced from said discharge port in mutually opposing relationship.

Claim 5

The apparatus described in claim 1 further including a top closure element mounted upon said vessel, a second outlet conduit coupled to said second outlet port in said vessel situated near the top thereof for drawing off fluid from the top of said vessel, said first and second outlet conduits having valve means therein for adjusting the rate of fluid flow therethrough.

Claim 6

Apparatus for separating two fluids of different specific gravities from a mixture of the two, comprising: a vessel, an inlet conduit extending upwardly in said vessel from a point near the bottom thereof, said conduit having an end positioned approximately at the central locus of said vessel, a discharge port at the end of said conduit, said discharge port being directed generally upwardly in said vessel; deflector means mounted upon said inlet conduit at points near the end thereof, said deflector means comprising a conically shaped collar member having the small end thereof secured around said conduit providing a closed lower end, said collar extending upwardly and outwardly and having the uppermost edge thereof positioned above said discharge port, a disc shaped member secured to said conduit by a plurality of extension legs, said disc member being positioned directly over and spaced above said discharge port, said disc member having a concave lower surface; said disc member having the lowermost edge thereof positioned below the uppermost edge of said collar; and at least one outlet conduit in said vessel near the bottom for drawing off the denser fluid from said vessel.

Claim 7

Apparatus for separating two fluids of different specific gravities from a mixture of the two, comprising: a vessel, an inlet conduit extending upwardly in said vessel from a point near the bottom thereof, said conduit having an end positioned approximately at the central locus of said vessel, a discharge port at the end of said conduit, said discharge port being directed generally upwardly in said vessel; deflector means mounted upon said inlet conduit at points near the end thereof, said deflector means comprising a conically shaped collar member having the small end thereof secured around said conduit providing a closed lower end, said collar extending upwardly and outwardly and having the uppermost edge thereof positioned above said discharge port, a disc shaped member secured to said conduit by a plurality of extension legs, said disc member being positioned directly over and spaced above said discharge port, said disc member having a concave lower surface; said disc member having the lowermost edge thereof positioned below the uppermost edge of said collar; and at least one outlet conduit in said vessel near the bottom for drawing off the denser fluid from said vessel.

Claim 8

The apparatus set forth in claim 5 further including a top closure member mounted upon said vessel, a second outlet conduit in said closure member for drawing off the lesser dense fluid from said vessel, said first and second outlet conduits each having valve means therein for independently controlling the rate of fluid flow in each conduit to maintain the rate of fluid separation within the vessel constant.

Claim 9

The apparatus set forth in claim 6 further including level sensing means mounted in said vessel for sensing the level of the interface between the separated oil in said vessel and the remainder of the fluid therein, said sensing means being coupled to valve control means, said valve control means being coupled to said valve means.

Claim 10

The apparatus set forth in claim 7 further including a third outlet conduit coupled to said vessel near the top thereof, pressure relief means coupled to said third conduit means for permitting the escape of separated gases from said vessel.

Claim 11

Apparatus for separating two fluids of different specific gravities from a mixture of the two, comprising: means forming a cylindrical chamber having an open upper end and a closed bottom end, means for affixing said chamber in the bottom of a storage vessel, an inlet conduit extending upwardly in said chamber from a point near the bottom end, said inlet conduit having a discharge port at the terminus thereof, a cylindrical extension sleeve mounted upon the upper end of said chamber, the upper discharge end of said sleeve having a deflector disc mounted thereover, means for adjustably varying the height of said sleeve to locate the discharge end of said sleeve at a chosen position within a vessel; deflector means mounted upon said inlet conduit, said deflector means comprising means for intercepting fluid discharged from said port including first intercepting means stationed opposite said discharge port and second intercepting means stationed opposite said first means whereby fluid directed against said first means is once reversed and directed against said second means whence said fluid is again reversed in direction, and an outlet port near the bottom of said chamber for drawing off separated fluid.

Claim 12

Apparatus for separating two fluids of different specific gravities from a mixture of the two, comprising: means forming a cylindrical chamber having an open upper end and a closed bottom end, means for affixing said chamber in the bottom of a storage vessel, an inlet conduit extending upwardly in said chamber from a point near the bottom end, said inlet conduit having a discharge port at the terminus thereof, a cylindrical extension sleeve mounted upon the upper end of said chamber, the upper discharge end of said sleeve having a deflector disc mounted thereover, means for adjustably varying the height of said sleeve to locate the discharge end of said sleeve at a chosen position within a vessel; deflector means mounted upon said inlet conduit, said deflector means comprising means for intercepting fluid discharged from said port including first intercepting means stationed opposite said discharge port and second intercepting means stationed opposite said first means whereby fluid directed against said first means is once reversed and directed against said second means whence said fluid is again reversed in direction, and an outlet port near the bottom of said chamber for drawing off separated fluid.

Claim 13

The apparatus set forth in claim 9 wherein said deflector means comprises: a first disc shaped plate member having a concave surface, said concave surface being positioned in opposed relation to said discharge port, a collar mounted upon said inlet conduit surrounding said discharge port, said collar having a closed lower end and an open upper end, said upper end having the edge thereof spaced from and above the outer peripheral edge of said disc member.

Claim 14

The apparatus set forth in claim 10 wherein the diameter of said cylindrical chamber and the diameter of the upper end of said collar are chosen such that there exists a narrow annular space therebetween.
