Abstract

A fluid control system includes a vortex separator, a fluid pump, an eductor, and an accumulator. The vortex separator has a fluid inlet arranged to receive a fluid, a first fluid outlet arranged output a first phase of the fluid, and a second fluid outlet arranged to output at least one of a non-condensable gas and a second phase of the fluid. The fluid pump has a pump outlet and a pump inlet that is fluidly connected to the first fluid outlet. The eductor has a first eductor inlet fluidly connected to the pump outlet, a second eductor inlet fluidly connected to the second fluid outlet, and an eductor outlet. The accumulator has an accumulator inlet fluidly connected to the eductor outlet and an accumulator outlet fluidly connected to the fluid inlet.

First claim

What is claimed is:

1. A fluid control system, comprising:
a vortex separator having a fluid inlet arranged to receive a fluid, a first fluid outlet arranged output a first phase of the fluid, and a second fluid outlet arranged to output at least one of a non-condensable gas and a second phase of the fluid;
a fluid pump having a pump outlet and a pump inlet fluidly connected to the first fluid outlet;
an eductor having an eductor liquid inlet fluidly connected to the pump outlet that receives the output of the fluid pump, a gas eductor inlet fluidly connected to the second fluid outlet that receives the second phase of the fluid from the vortex separator, and an eductor outlet; and
an accumulator having an accumulator inlet fluidly connected to the eductor outlet and an accumulator outlet fluidly connected to the fluid inlet.

2. The fluid control system of claim 1 , wherein the first phase of the fluid is a liquid phase.

3. The fluid control system of claim 1 , wherein the second phase of the fluid is at least one of a gas and a vapor.

4. The fluid control system of claim 1 , wherein the eductor is arranged to entrain the second phase of the fluid within the first phase of the fluid.

5. The fluid control system of claim 4 , wherein the accumulator is arranged to separate the entrained second phase of the fluid from the first phase of the fluid.

6. The fluid control system of claim 4 , wherein the accumulator is arranged to receive and store the second phase of the fluid and provide the first phase of the fluid to the fluid inlet.

7. A gas separating system provided with a fluid control system, comprising:
a vortex separator having a fluid inlet arranged to receive a fluid from an environmental control system, a first fluid outlet arranged to output a first phase of the fluid, and a second fluid outlet arranged to output a second phase of the fluid;
a fluid pump having a pump outlet and a pump inlet fluidly connected to the first fluid outlet;
an eductor having an eductor liquid inlet fluidly connected to the pump outlet that receives the output of the fluid pump, a gas eductor inlet fluidly connected to the second fluid outlet that receives the second phase of the fluid from the vortex separator, and an eductor outlet; and
an accumulator having an accumulator inlet fluidly connected to the eductor outlet and arranged to receive the first phase of the fluid and the second phase of the fluid and an accumulator outlet fluidly connected to the fluid inlet and arranged to output the first phase of the fluid.

8. The gas separating system of claim 7 , wherein the vortex separator includes a series of baffles disposed within a separator body arranged to separate the first phase of the fluid from the second phase of the fluid.

9. The gas separating system of claim 8 , wherein the separator body extends between a first end and a second end.

10. The gas separating system of claim 9 , wherein the fluid inlet is disposed proximate the first end.

11. The gas separating system of claim 9 , wherein the first fluid outlet is disposed proximate the second end.

12. The gas separating system of claim 9 , wherein the second fluid outlet is at least partially defined by the second end.

13. The gas separating system of claim 7 , wherein the accumulator includes a storage container that is arranged to store the second phase of the fluid.

14. The gas separating system of claim 7 , wherein the accumulator is arranged to separate the second phase of the fluid from the first phase of the fluid.
