Title
(EN) BAGHOUSE, LONG FILTER ASSEMBLY AND METHOD OF INSTALLATION
(FR) FILTRE A MANCHES, ENSEMBLE FILTRE LONG ET PROCEDE D'INSTALLATION
Abstract
(EN) A baghouse (20) includes a housing (22) divided into first and second plenums (42, 40) by a substantially planar tubesheet (44) having a plurality of openings (46), wherein the first plenum length is smaller than the second plenum length. A plurality of filter assemblies (24) are supported by the tubesheet (44) and hang vertically, each filter assembly including a first filter portion (80) and a second filter portion (82), the first and second filter portions sealingly connected by a connection device (200), wherein the connection device permits fluid communication between the first (80) and second (82) filter portions, and wherein the connection device has a strength sufficient to support the weight of the filter portions. Each first filter portion (80) and second filter portion (82) further includes a central tube (104) and a pleated filter element (120, 188) surrounding the central tube (104). A method of installing the filter assembly (24) in a baghouse (20) is also disclosed.
(FR) L'invention concerne un filtre à manches (22) comprenant un boîtier (22) divisé en des premier et deuxième plénums (42, 40) par une plaque tubulaire (44) sensiblement plane possédant plusieurs ouvertures (46), la longueur du premier plénum étant inférieure à celle du second. Plusieurs ensembles filtres (24) sont supportés par la plaque tubulaire (44) et pendent verticalement. Chaque ensemble filtre possède une première partie de filtre (80) et une deuxième partie de filtre (82), celles-ci étant reliées de manière étanche par un dispositif de liaison (200) permettant la communication fluidique entre elles (80, 82) et possédant une résistance suffisante pour supporter le poids des parties de filtre. Chacune des première (80) et deuxième (82) parties de filtre comprennent également un tube central (104) et un élément de filtre plissé (120, 188) entourant le tube central (104). Un procédé d'installation de l'ensemble de filtres (24) dans un filtre à manches (20) est également décrit.
