摘要： An exhaust gas filter is provided, including a honeycomb structure having a plurality of partition walls defining through-holes extending along an axial direction. The through-holes include first and second groups. The first group is plugged via first sealing members at a second axial end of the honeycomb structure, while the second group is plugged via second sealing members at the first axial end of the honeycomb structure. The first group of through-holes is adapted to receive exhaust gas, and trap therein fine particles. The first sealing members have a three-dimensional micropore structure that includes interconnected pores to allow blowback air to pass therethrough. The blowback air flows through both the first sealing members and the partition walls defining the second through-holes so as to remove the fine particles that have collected in the first through-holes. Additionally, an apparatus is provided including the honeycomb structure and a device for receiving particles that are removed from the honeycomb structure via flow of the blowback air.
