Patent number: 8758468Abstract: A filter for use in a baghouse. The filter is to be supported by a tubesheet that separates dirty fluid and clean fluid chambers of the baghouse. The filter including a filtration bag that has an open end adjacent to the tubesheet and an encircling sidewall that extends from the open end to a distal end along a direction of a central axis of the filtration bag. The bag sidewall permits passage of fluid there through so that the fluid may pass from the dirty fluid chamber to the clean fluid chamber and blocks passage of at least some particulate material against proceeding to the clean fluid chamber. The filter includes a cage located within the filtration bag. The cage has structure to permit expansion of the cage to increase a cage diameter that forces the bag sidewall taut against the cage.Type: GrantFiled: March 29, 2012Date of Patent: June 24, 2014Assignee: BHA Altair, LLCInventor: Tian Xuan Zhang

Patent number: 8734555Abstract: This disclosure describes examples of a seal element that can prevent leaks that occur due to sagging and/or displacement of a filter device from the tubesheet in a power generating system. The seal element can have a non-uniform profile that defines a material thickness for the seal element. In one example, the non-uniform profile defines an area or section of the seal element that is thicker relative to other areas or sections of the seal element. The thicker area corresponds to certain positions on the filter device that are susceptible to movement that can occur, e.g., due to particulate build-up during operation of the turbo-machine.Type: GrantFiled: June 12, 2012Date of Patent: May 27, 2014Assignee: BHA Altair, LLCInventor: Etienne Rene Jarrier
