Intake air filter system
View Patent ↗An air intake filter system for a gas turbine. The air intake filter system comprises a housing connectable with a gas turbine for fluid communication with the gas turbine. A frame is located within the housing. A filter assembly comprises a flange connectible with the frame to mount the filter assembly. The flange has a portion contained in a first plane that is adapted to extend in a substantially vertical direction when mounted in the frame. A filter portion is attached to the flange for filtering air therethrough that is communicated to the gas turbine. The filter portion includes filter media capable of separating moisture from air flowing through the filter portion. A moisture resistant first end is attached to the flange and filter portion. The first end has a portion contained in a second plane that extends at an acute angle relative to the first plane. The first end is adapted to form a drain surface to direct moisture away from the interior of the filter assembly.
1. An air intake filter system for a gas turbine, the air intake filter system comprising:
a housing connectable with a gas turbine for fluid communication with the gas turbine;
a frame located within the housing; and
a filter assembly comprising:
a flange connectible with the frame to mount the filter assembly, the flange having a portion contained in a first plane that is adapted to extend in a substantially vertical direction when mounted in the frame;
a filter portion attached to the flange for filtering air therethrough that is communicated to the gas turbine, the filter portion including filter media capable of separating moisture from air flowing through the filter portion; and
a moisture resistant first end attached to the flange and filter portion, the first end having a portion contained in a second plane that extends at an acute angle relative to the first plane, the first end adapted to form a drain surface to direct moisture away from the interior of the filter assembly.
2. The air intake filter system of claim 1 wherein at least one of the frame and housing have a channel for receiving moisture from the drain surface of the end of the filter assembly and direct the moisture away from the filter assembly.
3. The air intake filter system of claim 1 wherein the acute angle is the range of about 1° to 30°.
4. The air intake filter system of claim 1 further including a second end that is moisture resistant and adapted to be located opposite the first end.
5. The air intake filter system of claim 4 wherein the second end has a portion contained in a third plane, the second and third planes extending at an acute angle relative to the first plane.
6. The air intake filter system of claim 1 wherein the filter assembly is in the form of a V-cell mini-pleat filter.
7. A filter assembly comprising:
a flange connectible with a frame to mount the filter assembly, the flange having a portion contained in a first plane;
a filter portion attached to the flange, the filter portion including filter media capable of separating moisture from gas flowing through the filter portion; and
a moisture resistant first end attached to the flange and filter portion, the first end having a portion contained in a second plane that extends at an acute angle relative to the first plane, the first end adapted to form a drain surface to direct moisture separated by the filter media away from the interior of the filter assembly.
8. The air intake filter system of claim 7 wherein the acute angle is the range of about 1° to 30°.
9. The air intake filter system of claim 7 further including a second end that is moisture resistant and adapted to be located opposite the first end.
10. The air intake filter system of claim 9 wherein the second end has a portion contained in a third plane, the second and third planes extending at an acute angle relative to the first plane.
11. The air intake filter system of claim 7 wherein the filter assembly is in the form of a V-cell mini-pleat filter.
12. A filter assembly comprising:
a flange connectible with a frame to mount the filter assembly;
a filter portion attached to the flange, the filter portion including filter media capable of separating moisture from gas flowing through the filter portion; and
a moisture resistant first end attached to the flange and filter portion, the end being shaped and oriented at a non-orthogonal angle to the flange to drain and direct moisture separated by the filter media away from the interior of the filter assembly.
13. The air intake filter system of claim 12 further including a second end that is moisture resistant and adapted to be located opposite the first end.
14. The air intake filter system of claim 13 wherein, the flange has a portion contained in a first plane, the first end has a portion contained in a second plane, and the second end has a portion contained in a third plane, the second and third planes extending at an acute angle relative to the first plane.
15. The air intake filter system of claim 12 wherein the filter assembly is in the form of a V-cell mini-pleat filter.
