Abstract

An impact moisture separator for separating a liquid moisture from a compressed gas. The impact moisture separator includes a plurality of impact plates that are positioned within the inner region of the separator and may be downstream of at least one strut. The strut may be configured to disperse the flow of compressed gas. The impact plates each have a plurality of vanes that extend beyond a plate portion of the impact plates. The vanes are configured to provide a passage for the flow of compressed gases and are offset from the vanes of the adjacent, successive impact plate. Further, the impact plates and strut(s) are tilted toward the incoming flow of compressed gas so as to assist in influencing the downward flow of the compressed gas, and thereby facilitate the flow of separated liquid moisture toward a reservoir of the housing.

First claim

The invention claimed is:

1. An impact moisture separator for separating a liquid moisture from a compressed gas, the impact moisture separator comprising:
a housing having an inner region; and
a plurality of impact plates arranged in series within the inner region, the plurality of impact plates each having a plate portion and a plurality of vanes, the plate portion having a front side, a rear side, a base portion, and an upper portion, the front side being upstream, and on an opposite side of the plate portion, of the rear side, the upper and base portions being on opposing sides of the plate portion, the base portion being proximally adjacent to a lower inner surface of the housing,
the plurality of vanes configured to provide a passage for the flow of compressed gas, the passage defined by opposing vane surfaces to convey the flow of compressed gas traversing the passage in a direction extending along a decline from at least the front side to the rear side of the plate portion, the decline configured to direct the flow of compressed gas in a direction that influences the flow of coalesced liquid moisture that has collected on the front side of the plate portion of the subsequent impact plate of the plurality of impact plates toward the base portion of the subsequent impact plate,
the front side of the plate portion being angularly offset from an adjacent portion of the lower inner surface of the housing by a plate tilt angle that is less than 90 degrees such that the front portion of the plate portion is positioned upstream relative to a location of an opposing lower portion of the plate portion,
the plurality of vanes for each of the plurality of impact plates are offset from the plurality of vanes of an adjacent impact plate of the plurality of impact plates to provide an impact of at least a portion of the flow of compressed gas flowing through the plurality of vanes with the front side of the plate portion of the adjacent impact plate.

2. The impact moisture separator of claim 1 , wherein a base portion of the plate portion is not perpendicular to at least the front side of the plate portion.

3. The impact plate moisture separator of claim 2 , wherein the decline of the passage is along a vane angle that is larger than a base tilt angle of the base portion.

4. The impact plate moisture separator of claim 3 , wherein the vane angle and the base tilt angle are configured to influence the compressed gas flowing through the plurality of vanes to flow in a generally downward direction.

5. The impact plate moisture separator of claim 4 , wherein the vane angle and the base tilt angle are configured for the compressed gas to strike an adjacent impact plate of the plurality of impact plates at an impingement angle between 0 degrees and 30 degrees, inclusive.

6. The impact moisture separator of claim 4 , wherein each of the plurality of vanes include a front vane wall and a rear vane wall, the front vane wall extending a length of the passage beyond the front side of the plate portion, and the rear vane wall extending the length of the passage beyond a rear side of the plate portion, at least the rear vane wall configured to direct the flow of compressed gas passing through the passage into the plate portion of an adjacent impact plate of the plurality of impact plates.

7. An impact moisture separator for separating a liquid moisture from a compressed gas, the impact moisture separator comprising:
a housing having an inner region; and
a plurality of impact plates positioned within the inner region, the plurality of impact plates each having a plate portion and a plurality of vanes, the plurality of vanes each configured to provide a passage defined by neighboring vane surfaces to convey the compressed gas traversing the passage in a direction along a decline for the flow of the compressed gas through at least the plate portion, the decline configured to influence the flow of coalesced liquid moisture from the flow of compressed gas that has collected on a front portion of a plate portion of a subsequent impact plate of the plurality of impact plates toward a base portion of the subsequent impact plate,
the front portion of the plate portion being angularly offset from an adjacent lower inner surface of the housing by a plate tilt angle that is less than 90 degrees, and wherein the plurality of vanes for each of the plurality of impact plates are offset from the plurality of vanes of an adjacent impact plate of the plurality of impact plates,
wherein each of the plurality of vanes include a front vane wall and a rear vane wall, the front vane wall extending a length of the passage beyond a front side of the plate portion, and wherein the front vane wall of at least a portion of the plurality of vanes extends toward an upstream gap between the rear vane wall of two or more of the plurality of vanes of an adjacent, upstream impact plate of the plurality of impact plates, the rear vane wall configured to direct at least a portion of compressed gas flowing through the passage into impact with the front portion of the adjacent impact plate.

8. An impact moisture separator for separating a liquid moisture from a compressed gas, the impact moisture separator comprising:
a housing having an inner region, the inner region including a reservoir;
at least one strut positioned within the inner region and in a path of incoming flow of the compressed gas; and
a plurality of impact plates arranged in series within the inner region downstream of the at least one strut, the plurality of impact plates each having a plate portion and a plurality of vanes, the plurality of vanes configured to provide a passage for the flow of the compressed gas, the passage defined by adjacent vane surfaces to convey the flow of compressed gas traversing the passage in a direction extending along a decline from at least a front side to a rear side of the plate portion, the decline configured to direct the flow of compressed gas in a direction that influences the flow of coalesced liquid moisture from the flow of compressed gas that has collected on the front side of the plate portion of the subsequent impact plate of the plurality of impact plates toward a base portion of the subsequent impact plate, the plurality of vanes for each of the plurality of impact plates being offset from the plurality of vanes of an adjacent impact plate of the plurality of impact plates and oriented to provide an impact of at least a portion of the flow of compressed gas flowing through the plurality of vanes with a front side of the plate portion of the adjacent impact plate, and further wherein the plurality of impact plates are tilted within the inner region generally toward the flow of incoming compressed gas to influence the compressed gas flowing through the housing in a generally downward direction.

9. The impact moisture separator of claim 8 , wherein the plurality of impact plates are tilted within the inner region by a plate tilt angle that is less than 90 degrees.

10. The impact moisture separator of claim 9 , wherein the at least one strut is tilted in the same general direction as the plurality of impact plates within the inner region.

11. The impact moisture separator of claim 10 , wherein only a portion of the base portion of the plate portion of the plurality of impact plates abuts a lower inner surface of the housing to define a space for liquid moisture to travel along the lower inner surface and toward the reservoir.

12. The impact moisture separator of claim 10 , wherein the housing further includes an impinging surface, the impinging surface extending from an inner rear surface of the housing and is positioned to traverse
