Embodiment Construction

[0022] Example embodiments incorporating one or more aspects of the present invention are described and illustrated in the figures. These illustrated examples are not intended to limit the invention. For example, one or more aspects of the invention can be used in other embodiments and even other types of devices. Furthermore, certain terms are used herein for convenience only and should not be construed as limiting the invention. Also, in the drawings, the same reference numerals are used to designate the same elements.

[0023] figure 1 An example of a baghouse 10 is shown schematically as an environment within which the invention may be used. The baghouse 10 may be defined by a closed housing 12 and may be divided into two sections, a dirty fluid chamber 14 and a clean fluid chamber 16 . Dirty fluid chamber 14 and clean fluid chamber 16 are examples of dirty fluid chambers and clean fluid chambers, respectively. The dirty fluid chamber 14 and the clean fluid chamber 16...

Abstract

The invention relates to a variable length bag cage. A filter for use within a baghouse and for filtering particulate material from fluid flow is provided. The filter is to be supported by a tubesheet of the baghouse. The filter includes an elongate bag that has an open end adapted to be disposed adjacent to the tubesheet and an encircling sidewall that extends from the open end to a distal end of the bag. The sidewall permits passage of fluid there through so that the fluid may pass through the bag and blocks passage of particulate material. The filter includes an elongate cage that is located within and supporting the bag and that has a variable effective length. The filter includes cage-associated structure for increasing the effective length of the cage to maintain the sidewall to be taut adjacent the cage. The cage may include structure inhibiting movement of the cage. The filter may be part of a baghouse assembly.

Description

technical field [0001] The present invention relates generally to fluid (eg, air) filters, and more particularly, to bag-type fluid filters that may be used in baghouses. Background technique [0002] Fluid filters are known and used in many different applications, including baghouses. Each baghouse may be provided with one or more fluid filters to filter dirty fluid (eg air) in various functions such as fuel based power generation, chemical / cement / mineral processing, incineration, etc. Current state of the art filters include filter cartridges having filter media and associated structures arranged to enclose cells of the cage and "bag" media. [0003] Focusing on bagged media, the underlying cage is generally elongated and has a cylindrical shape. The filter bag generally has a shape corresponding to the shape of the cage surrounded by the filter bag. It is to be understood that placing the filter media on the cage includes an insertion movement of the cage into a bag, w...
