PROBLEM TO BE SOLVED: To provide a retainer for a ceramic filter where the ceramic filter is stably fixed and reinforced and to provide a partition wall type dust collector.SOLUTION: A retainer 11 for a ceramic filter is constituted with: an annular retainer flange 21; a plurality of fixing rings 23 formed into an annular shape with a metal wire at predetermined intervals; and a plurality of vertical wires 25 joined at the outside of the fixing rings 23. The retainer 11 for the ceramic filter does not thermally expand and is apart from the inner surface 13a of a hollow portion 31 by a predetermined distance in a state that a partition wall type dust collector is not operated. On the other hand, the retainer 11 for the ceramic filter is abutted to the inner surface 13a of the hollow portion 31 of the ceramic filter 13 by thermal expansion and the inner surface 13a is pressed toward the outside when the partition wall type dust collector is operated and temperature is increased and then the ceramic filter 13 is fixed and reinforced.SELECTED DRAWING: Figure 2 |
