| 摘要 |
The present invention concerns a flue gas filter, in particular for filtering exhaust gas from diesel engines, comprising a casing having an exhaust gas inlet and an exhaust gas outlet and a filter body arranged in the casing, the filter body being composed of at least two segments which are of a porous heat-resistant material and which extend in the axial direction of the casing, the filter segments being arranged adjacent to each other, and an electrical heating element being arranged in at least one axial interstice between adjacent filter segments. The heating element may comprise an electrical resistance heating means enclosed in an electrically insulating material. The filter segments may be shaped substantially as a circle sector and the segments together may cross-sectionally substantially constitute a circle. The filter segments are preferably made of porous SiC. |
