Abstract
A filter system and clamp system for a gas turbine air inlet uses a single clamp system that allows for securing in place both a first element and a second element on the grid of the gas turbine air inlet. The clamp system can be released to allow for services of the first filter element, while the second filter element remains in sealing engagement with the grid.
Claims19
A clamp system for releasably attaching a filter assembly to a support grid;
- the clamp system comprising:
- (a) an elongated support tube with first and second opposite open ends, a first slide channel adjacent the first end;
- and a second slide channel adjacent the second end;
- (b) a first clamp slidably mounted in the first open end;
- (c) a second clamp slidably mounted in the second open end;
- (d) a first slide pin arrangement slidably mounted in the first slide channel between a locked and a released position;
- (e) a second slide pin arrangement slidably mounted in the second slide channel between a locked and a released position;
- (f) an elongated omega clamp removably mounted to cover the support tube;
- the omega clamp having first and second spaced through slots;
- (i) the first through slot slidably accommodating a portion of the first slide pin arrangement;
- (ii) the second through slot slidably accommodating a portion of the second slide pin arrangement;
- (g) first and second pivot rods extending through and connecting the omega clamp and the support tube;
- the first and second pivot rods each having a hinge point in the support tube and a pivot axis along a length of the support tube between the first and second open ends of the support tube;
- wherein, when the first and second slide pin arrangements are slid to the released position, the omega clamp is free to be pivoted with the first and second pivot rods along the pivot axis away from covering the support tube.
A clamp system for releasably attaching a filter assembly to a support grid;
- the clamp system comprising:
- (a) one or more clamp rods;
- (b) a first elongated support member with openings, each opening being sized to fit over one of the clamp rods;
- (c) a first slide plate slidably mounted in the first support member;
- (i) the first slide plate having openings alignable with the openings in the first support member;
- (ii) the first slide plate having an end handle;
- (c) a second elongated support member with openings, each opening in the second support member sized to fit over one of the clamp rods;
- and
- (d) one or more handgrips, each handgrip constructed and arranged to engage one of the clamp rods and apply an axial force against the second support member.
A filter system comprising:
- (a) a support grid having a frame with opposite upstream and downstream sides;
- (b) a first filter element oriented along the upstream side of the support grid;
- (c) a second filter element oriented on the support grid on the downstream side directly across and opposing the first filter element;
- and
- (d) a single clamp system releasably securing both the first filter element and the second filter element to the frame;
- (e) a plurality of clamp rods extending from the support grid;
- (f) a first elongated support member holding a first slide plate and positioned over the clamp rods;
- (i) the first support member being positioned against the second element gasket;
- and
- (g) a second elongated support member positioned over the clamp rods and against the first element gasket, such that the first element gasket is positioned between and against the first support member and second support member.
