Abstract

A separator apparatus includes an intake nozzle, first cyclone device, and a second cyclone device. The first and second cyclone devices each include an inlet section, a scroll, a barrel centered on a first axis, a vortex finder, and an underflow portion. The scroll is attached to the inlet section and to the barrel such that the scroll connects the inlet section to the barrel. The vortex finder has a vortex tube arranged concentrically on the axis in an interior volume of barrel. The underflow portion defines an annular gap in fluid connection with the interior volume. The intake nozzle is fluidly connected to the inlet sections of the first and second cyclone devices.

First claim

What is claimed is:

1. A separator apparatus comprising:
a first cyclone device comprising:
a first inlet section having a first end and a second end, wherein a cross-sectional area of the first inlet section increases from the first end to the second end;
a first scroll comprising a curved member;
a first barrel centered on a first axis, the barrel defining a first interior volume, the first barrel having a diameter, a first end, and a second end, wherein the scroll is attached to the first inlet section and to the first barrel, and connects the first inlet section to the first barrel;
a first vortex finder comprising a first vortex tube arranged concentrically on the first axis in the first barrel on the first axis adjacent the first end of the first barrel; and
a first underflow portion comprising a first conical member and a first underflow body, the first underflow portion defining a first annular gap in fluid connection with the first interior volume;
a second cyclone device comprising:
a second inlet section having a first end and a second end, wherein a cross-sectional area of the second inlet section increases from the first end to the second end;
a second scroll;
a second barrel centered on a second axis, the barrel defining a second interior volume, the second barrel having a diameter, a first end, and a second end, wherein the scroll connected the second inlet section to the second barrel;
a second vortex finder having a second vortex tube arranged on the second axis concentrically in the second barrel on the axis adjacent the first end of the second barrel; and
a second underflow portion having a second conical member and a second underflow cylinder, the second underflow portion defining a second annular gap in fluid connection with the second interior volume; and

an intake nozzle fluidly connected to the first inlet section and second inlet section.

2. The separator apparatus of claim 1 , wherein the first conical member comprises:
a first cone connected to the barrel at the second end, the first cone having a first diameter at a first end and a second diameter at a second end, wherein the first diameter is equal to the diameter of the barrel, wherein the first diameter is greater than the second diameter.

3. The separator apparatus of claim 2 , wherein the curved member is a circular ramp.

4. The separator apparatus of claim 2 , wherein the first underflow body comprises:
an inner cylinder having an exterior surface and an interior surface, wherein the exterior surface of the inner cylinder and the first end of the first cone define the first annular gap.

5. The separator apparatus of claim 4 , wherein the first underflow portion further comprises a first insert arranged in the underflow body, wherein the first insert has a diameter.

6. The separator apparatus of claim 5 , wherein the interior surface of the inner cylinder defines an opening with a diameter; wherein the diameter of the opening is equal to the diameter of the first insert.

7. The separator apparatus of claim 5 , wherein the first cyclone device further comprises:
a stabilizer attached to the first insert.

8. The separator apparatus of claim 7 , wherein the stabilizer comprises an arm, attached at a first end to the first insert, and a vortex breaker attached to a second end of the arm.

9. The separator apparatus of claim 4 , wherein the second underflow portion comprises:
a second cone connected to the barrel at the second end, the cone having a first diameter at a first end and a second diameter at a second end, wherein the first diameter is equal to the diameter of the barrel, wherein the first diameter is greater than the second diameter; and
a second underflow body defining the second annular gap.

10. The separator apparatus of claim 1 , wherein the second conical member comprises:
a second cone connected to the barrel at the second end, the cone having a first diameter at a first end and a second diameter at a second end, wherein the first diameter is equal to the diameter of the barrel, wherein the first diameter is greater than the second diameter; and
a second underflow body.

11. The separator apparatus of claim 10 , wherein the second underflow body comprises:
an inner cylinder having an exterior surface and an interior surface; wherein the exterior surface of the inner cylinder and the second cone define the second annular gap.

12. The separator apparatus of claim 11 , wherein the second underflow portion further comprises a second insert arranged in the underflow body, wherein the second insert has a diameter.

13. The separator apparatus of claim 12 , wherein the interior surface of the inner cylinder defines an opening with a diameter; wherein the diameter of the opening is equal to the diameter of the second insert.

14. The separator apparatus of claim 12 , wherein the second cyclone device further comprises:
a stabilizer attached to the second insert.

15. The separator apparatus of claim 14 , wherein the stabilizer comprises an arm, attached at a first end to the second insert, and a vortex breaker attached to a second end of the arm.

16. The separator apparatus of claim 1 , wherein the first inlet section is adjacent the second inlet section, wherein a divider separates the first inlet section and the second inlet section.

17. The separator apparatus of claim 1 , further comprising a first feed chamber defined in the annular space between the first barrel and the first vortex finder.

18. The separator apparatus of claim 1 , further comprising a second feed chamber defined in the annular space between the second barrel and the second vortex finder.

19. The separator apparatus of claim 1 , wherein the first vortex tube comprises a first entrance in the first interior volume of the first barrel and a first discharge outlet, wherein the first discharge outlet extends through the first end of the first barrel.

20. The separator apparatus of claim 19 , wherein the second vortex tube comprises a second entrance in the second interior volume of the second barrel and a second discharge outlet, wherein the second discharge outlet extends through the first end of the second barrel.

21. The separator apparatus of claim 20 , wherein the second inlet section is configured to receive a mixture having a first substance and a second substance, and wherein the second vortex tube is configured to receive the first substance at the second entrance and discharge the first substance at the second discharge outlet.

22. The separator apparatus of claim 21 , wherein the first substance is lighter than the second substance.

23.
