Abstract
A filter assembly for a gas turbine system includes a filter element configured to remove entrained particles from air which passes through the filter element in a first direction toward a central air passageway. A motion generator arranged to rotate the filter element about a longitudinal axis extending in an airflow direction of the air passageway to cause particles accumulated on the filter element to fall downwardly away from the filter element due to gravity.
Claims16
A gas turbine system comprising:
- a compressor;
- a combustor connected to the compressor;
- a turbine connected to the combustor;
- and
- a filter house system connected as an input to the compressor, wherein the filter house system comprises a filter assembly, the filter assembly comprising,
- a filter element having a porous structure configured to pass air therethrough, the filter element being arranged so as to define a hollow interior forming an air passageway, the filter element being configured to remove entrained particles from air which passes through the filter element in a first direction toward the air passageway;
- a rotary motion generator arranged to rotate the filter element about a longitudinal axis extending in an airflow direction of the air passageway to cause particles accumulated on the filter element to fall downwardly away from the filter element due to gravity, wherein the rotary motion generator is one of a motor, a pneumatic-based device, a hydraulic-based device, or a magnet-based device;
- piping extending into the air passageway and configured to convey air arranged to pass through the filter element in a second direction opposite the first direction to cause particles accumulated on the filter element to be removed from the filter element;
- and
- a plurality of nozzles extending from the piping at spaced-apart locations in the first direction, wherein the piping is configured to rotate within the air passageway such that the nozzles are rotated about the longitudinal axis.
