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

A dust collecting apparatus for purifying high-temperature gases applied thereto, the dust collecting apparatus having an upright cylindrical housing provided therein with a plurality of circumferentially spaced lateral support beams which are arranged to form a vertical gas induction passage at the center of said upright cylindrical housing and a plurality of circumferentially spaced vertical discharge passages located along an internal peripheral surface of said cylindrical housing, at least one filter assembly unit composed of a plurality of circumferentially spaced filter assemblies placed on the support beams of said cylindrical housing in such a manner that the filter assemblies are exposed at their inner ends to the vertical gas induction passage and at their outer ends to the respective vertical discharge passages, said filter assemblies each being composed of a plurality of filter elements assembled as a unit, each of said filter elements being made of porous ceramic material and having a thin walled cellular structure formed with a plurality of axial passages separated from each other by thin partition walls, wherein a first group of said axial passages are opened at their one ends to introduce therein high-temperature gases to be purified from the vertical gas induction passage and closed at their other ends, while a second group of said axial passages are closed at their one ends and opened at their other ends to discharge purified gases therefrom into each of the vertical discharge passages, wherein an internal upright support housing is disposed within said upright cylindrical housing concentrically therewith to form the vertical gas induction passage, said filter assemblies are coupled in an air-tight manner at their inner ends with corresponding openings formed in a peripheral wall of said support housing, and said internal upright support housing is vertically displaceably coupled at its upper end with a gas induction duct connected to an upper end of said cylindrical housing.
