Filter assembly including pleat tip shapes
Solutions for efficiently filtering air for a machine are disclosed. In one embodiment, a filter element for a filter assembly of a rotary machine is provided. The filter element includes: a first set of pleats, each pleat including a first tip radius and a first spacing; and a second set of pleats, each pleat including a second tip radius and a second spacing, wherein the first and second set of pleats are positioned upon a continuous filter media.
1. A filter element for a filter assembly, the filter element comprising:
a first set of pleats, each pleat including a first tip radius and a first spacing, wherein the first tip radius and the first spacing are at a circumference of the filter element; and
a second set of pleats, each pleat including a second tip radius and a second spacing wherein the second tip radius and the second spacing, are at the circumference of the filter element,
wherein the first and second set of pleats are positioned upon a continuous filter media, wherein the first tip radius is different from the second tip radius, and wherein the first spacing is larger than the second spacing.
2. The filter element of claim 1 , wherein a pleat height for each pleat of the first set of pleats and a pleat height for each pleat of the second set of pleats is substantially equal.
3. The filter element of claim 1 , further comprising a third set of pleats, each pleat including a third tip radius and a third spacing.
4. The filter element of claim 3 , wherein the third tip radius is different from the second tip radius.
5. The filter element of claim 4 , wherein the second spacing is larger than the third spacing.
6. A system comprising:
a gas turbine; and
a filter assembly operably connected to the gas turbine, the filter assembly comprising:
a first set of pleats, each pleat including a first tip radius and a first spacing, wherein the first tip radius and the first spacing are at a circumference of the filter assembly; and
a second set of pleats, each pleat including a second tip radius and a second spacing wherein the second tip radius and the second spacing are at the circumference of the filter assembly,
wherein the first and second set of pleats are positioned upon a continuous filter media, wherein the first tip radius is different from the second tip radius, and wherein the first spacing is larger than the second spacing.
7. The system of claim 6 , wherein a pleat height for each pleat of the first set of pleats and a pleat height for each pleat of the second set of pleats is substantially equal.
8. The system of claim 6 , further comprising a third set of pleats, each pleat including a third tip radius and a third spacing.
9. The system of claim 8 , wherein the third tip radius is different from the second tip radius.
10. The system of claim 9 , wherein the second spacing is larger than the third spacing.
11. A system comprising:
a gas turbine;
a heat exchanger operably connected to the gas turbine;
a steam turbine operably connected to the heat exchanger; and
a filter assembly operably connected to the gas turbine, the filter assembly comprising:
a first set of pleats, each pleat including a first tip radius and a first spacing, wherein the first tip radius and the first spacing are at a circumference of the filter assembly; and
a second set of pleats, each pleat including a second tip radius and a second spacing, wherein the second tip radius and the second spacing are at the circumference of the filter assembly,
wherein the first and second set of pleats are positioned upon a continuous filter media, wherein the first tip radius is different from the second tip radius, and wherein the first spacing is larger than the second spacing.
12. The system of claim 11 , wherein a pleat height for each pleat of the first set of pleats and a pleat height for each pleat of the second set of pleats is substantially equal.
13. The system of claim 11 , further comprising a third set of pleats, each pleat including a third tip radius and a third spacing.
14. The system of claim 13 , wherein the third tip radius is different from the second tip radius, and wherein the second spacing is larger than the third spacing.
