A dust collecting apparatus of the type which includes an upright cylindrical housing (11) provided therein with a plurality of circumferentially spaced lateral support beams (12, 13) arranged to form a vertical gas induction passage (P1) at the center of the housing and a pluraity of circumferentially spaced vertical discharge passages (P2) along an internal peripheral surface of the housing, and plural sets of circumferentially spaced filter assemblies (21) vertically mounted on the support beams in such a manner that the filter assemblies (21) are exposed at their inner ends to the gas induction passage (P1) and at their outer ends to the discharge passages (P2), wherein an internal upright support housing (22) is disposed within the cylindrical housing (11) concentrically therewith to form the vertical gas induction passage (P1), the filter assemblies (21) are coupled at their inner ends with the corresponding openings (22d) formed in the peripheral wall of the support housing (22), and the support housing (22) is vertically displaceably coupled at its upper end (22b) with a gas indution duct (15) connected to the upper end of the cylindrical housing (11). <IMAGE> |
