Modular Compartments Patents (Class 55/341.5)
-
Patent number: 8986411Abstract: A modular design for large pulse jet fabric filters (PJFF) is divided into similar compartments, which are each “shop-fabricated” in quarter sections prior to delivery to the power plant site. The quarter sections of the compartments are modular and sized so that they can be fabricated at a shop located away from the power plant site and transported by truck over public roads to the power plant site. Once delivered to the site, the quarter sections are bolted together and seal welded to form a PJFF compartment, without requiring additional internal fabrication or welding. The assembled compartment is then lifted onto the support structure as an assembled unit and bolted and/or welded in place. The additional components of the PJFF may also be shop-fabricated offsite to further the benefits of the modular design.Type: GrantFiled: January 24, 2013Date of Patent: March 24, 2015Assignee: Clyde Bergemann Power Group Americas Inc.Inventors: Gregory J. Golub, Gregory C. Swartz, Mark Steven Dutchess

Publication number: 20100101195Abstract: A baghouse and filter assembly are provided for at least partially removing particulate matter from a gas stream. The filter assembly includes first and second filter portions to be coupled together by a coupler for establishing fluid communication between the first and second filter portions when connected. The coupler includes a first coupling portion including a side wall defining an interior passage through which the gas stream can pass in an axial direction between the first and second filter portions, and one or more flanges projecting from said side wall, the one or more flanges supporting a plurality of male studs. The coupler further includes a second coupling portion including a plurality of female keyhole-shaped receivers spaced apart for receiving at least a portion of the male studs and coupling the first coupling portion to the second coupling portion.Type: ApplicationFiled: October 28, 2008Publication date: April 29, 2010Applicant: BHA GROUP, INC.Inventors: Jack T. Clements, Gerry E. Maddocks

Publication number: 20100071322Abstract: A baghouse and filter assembly are provided for at least partially removing particulate matter from a gas stream. The filter assembly includes a first filter portion to be supported within the baghouse adjacent to an opening defined by a tube sheet, a first generally-tubular frame, and a first pleated filter media adjacent to the first generally-tubular frame. A second filter portion includes a second generally-tubular frame and a second pleated filter media disposed adjacent to the second generally-tubular frame. A coupler is provided for connecting the first filter portion to the second filter portion and establishing fluid communication between the first and second filter portions when connected. The coupling includes a first coupling portion including a side wall defining a receiver, as well as a lug clip disposed adjacent to the receiver. The lug clip us substantially-elastically displaced in a radial direction from an unbiased position during connection of the first and second filter portions.Type: ApplicationFiled: September 24, 2008Publication date: March 25, 2010Applicant: BHA Group, Inc.Inventor: Jack T.

Patent number: 6936085Abstract: A specially arranged vacuum loader and industrial dust collector with a perforated plate tangential cyclone separator is provided to efficiently remove, readily collect, effectively separate and safely dispose of wet, dry and fibrous materials, including liquids and slurries. The special vacuum loader and industrial dust collector has a solids-gas separation compartment comprising a tangential cyclone separator, preferably a perforated plate tangential separator, which is positioned generally alongside and laterally offset from one or more filtering compartments to minimize turbulence and re-entrainment of the collected particulate material.Type: GrantFiled: March 17, 2003Date of Patent: August 30, 2005Assignee: DeMarco Maxvac CorporationInventor: Thomas M. DeMarco
