Vibration Behavior of Ceramic Hot Gas Filter Elements: Analysis and Characterization of Mechanical Properties

PDF Version Also Available for Download.

Description

The objective of this study is to evaluate the mechanical properties of the cylindrical ceramic filter elements under vibration. These vibrations with different frequencies and amplitudes occur particularly in up/down-turning periods and during pulse cleaning but even under regular operation conditions. The geometry of a filter element with a wall thickness of about 10 mm, an outer diameter of 60 mm and an overall length of about 1500 mm with a porous support structure is not typical for ceramic materials. Therefore the risk of mechanical fatigue is high. As a result of the theoretical calculations an optimization of the element ... continued below

Description

The objective of this study is to evaluate the mechanical properties of the cylindrical ceramic filter elements under vibration. These vibrations with different frequencies and amplitudes occur particularly in up/down-turning periods and during pulse cleaning but even under regular operation conditions. The geometry of a filter element with a wall thickness of about 10 mm, an outer diameter of 60 mm and an overall length of about 1500 mm with a porous support structure is not typical for ceramic materials. Therefore the risk of mechanical fatigue is high. As a result of the theoretical calculations an optimization of the element geometry shall be achieved. The optimization has to take into account the possibilities for an industrial fabrication of the elements, the possibility of a substitution in existing filter systems and of course a high filter area similar to the usual geometry has to be guaranteed.
