Exhaust gas filter and apparatus for treating exhaust gases

An apparatus for treating exhaust gas, comprising:

• a honeycomb structure having a plurality of partition walls defining a plurality of througholes extending along an axial direction, the honeycomb structure having first and second opposite axial ends, the througholes forming two groups, a first group which is open at the first axial end and plugged via first sealing members at the second axial end, and a second group which is plugged via second sealing members at the first axial end and open at the second axial end, wherein the first group of througholes is adapted to receive exhaust gas, the second group of througholes is adapted to receive blowback air, and the first sealing members have a three-dimensional micropore structure including interconnected pores that allow blowback air to pass therethrough such that said first sealing members have an air permeation time that is less than an air permeation time of the partition walls of the honeycomb structure;
• and
• a device for receiving fine particles that are collected by the honeycomb structure and removed therefrom by flow of blowback air through the honeycomb structure.
