Abstract
A particle separator includes a housing through which a flow stream is directed. A number of guide vanes are disposed in the housing. The guide vanes have a profile wherein the flow stream is guided to follow the profile. The guide vanes have a wall surrounding an open interior that defines a vane plenum. A plurality of through-holes extend through the wall of the guide vane. The through-holes are open to the flow stream and to the vane plenum. A duct connects with the vane plenum and is configured to discharge particles collected in the vane plenum.
Claims20
A particle separator comprising:
- a housing through which a flow stream is directed;
- a number of guide vanes disposed in the housing, at least one of the guide vanes having a profile wherein the flow stream is guided to follow the profile, at least one of the guide vanes having a wall structure surrounding an open interior defining a vane plenum, with a plurality of through-holes extending through the wall structure of the guide vane;
- wherein first ends of the through-holes are open to the flow stream and second ends of the through-holes are open to the vane plenum;
- a common plenum defined by the housing, wherein the vane plenum is open to the common plenum;
- and
- a scavenge duct connected with the common plenum and configured to discharge particles collected in the vane plenum and to self-refresh the particle separator.
A particle separator for an inlet duct comprising:
- a housing through which a flow stream is directed;
- a plurality of guide vanes disposed in the housing, each of the guide vanes having a profile wherein the flow stream is guided to follow the profile, each of the guide vanes having a wall structure surrounding an open interior defining a vane plenum, with a plurality of through-holes extending through the wall structure of the guide vane connecting the flow stream with the vane plenum, wherein first ends of the through-holes are open to the flow stream and second ends of the through-holes are open to the vane plenum;
- a common plenum defined by the housing, wherein each of the vane plenums is open to the common plenum;
- and
- a scavenge duct connected with the common plenum and configured to discharge particles collected in the vane plenums and to self-refresh the particle separator.
A particle separator for an inlet duct channeling a flow stream, the particle separator comprising:
- a plurality of guide vanes aligned with one another and configured to separate the flow stream into multiple flow channels, the guide vanes each having a profile wherein the flow channels follow the profile and each flow channel has a zero line of sight so that the flow stream must turn in the flow channel,
- wherein each guide vane has a wall structure surrounding an open interior defining a vane plenum, with a plurality of through-holes extending through the wall structure of the guide vane connecting the flow stream with the vane plenum,
- wherein first ends of the plurality of through-holes are open to the flow stream and second ends of the plurality of through-holes are open to the vane plenum,
- wherein the flow stream travels in an upstream to downstream direction, and
- wherein at least some of the plurality of through-holes are inclined at an angle so that each of their respective first end is located at an upstream position relative to their respective second end.
