    • An arrangement for filtering dust from hot gas, in which a housing is provided with a dirty-gas zone and a clean-gas zone, as well as porous-walled hollow structures that are continuous with the exception of an outlet opening into the clean-gas zone. A filtering tube surrounds the outlet and has an area with spherically convex base that rests against a support fixed in the clean-gas zone. Between the base of the tube and the support, there is an annular adapter which has a coefficient of linear heat expansion that is approximately at least that of the tube. The annular adapter rests against the convex base of the tube, and has a flat surface that rests against a matching flat surface on the support, so that the adapter can slide horizontally over the support that is fixedly connected to the clean-gas zone. The sliding of the adapter relative to the support occurs over oppositely-lying flat parallel surfaces, one of which is on the support and the other is on the adapter. The support and the adapter are free to expand in all directions due to the sliding action that is made possible.
    • 用于过滤来自热气体的灰尘的装置,其中壳体设置有脏气区域和清洁气体区域,以及除了进入清洁气体区域的出口开口之外的连续的多孔壁中空结构, 气区。 过滤管围绕出口并且具有球形凸起的基部的区域,其抵靠固定在清洁气体区域中的支撑件。 在管的基部和支撑件之间,存在一个环形适配器,其具有大致至少是管的热膨胀系数。 环形适配器靠在管的凸形基部上,并且具有平坦表面,该平坦表面靠在支撑件上的匹配的平坦表面上,使得适配器可以水平地滑动在固定地连接到清洁气体区域的支撑件上。 适配器相对于支撑件的滑动发生在相对平坦的平坦平行表面上,其中一个平坦的平面位于支撑件上,另一个位于适配器上。 由于可能的滑动动作,支架和适配器可以在各个方向自由扩展。
