Hereinafter, the case where six filter units 300 are provided for ease of explanation will be described.

8, for example, the gas distribution portion 610 is extended to the rear side of the second case 200, one end of which communicates with the exhaust gas inlet port 101 and the other end of which is rearward in the traveling direction of the gas And a distribution pipe 611 in which a plurality of gas flow holes 612 are provided.

In this case, the exhaust gas flowing through the exhaust gas inlet 101 once enters the inside of the distribution pipe 611 and then flows through the plurality of gas flow holes 612 toward the first to third filter units 310, So that abnormal occurrence of the first to third filter units 310, 320, and 330 can be minimized and the durability can be further increased.

9, for example, the distribution pipe 611 gradually increases in the direction from the exhaust gas inlet 101 side toward the purge gas outlet 102 so as to further enhance the gas distribution effect as described above, And is tapered so as to decrease in diameter. In this structure, since the flow velocity gradually increases as the exhaust gas moves from the exhaust gas inlet 101 to the third filter unit 330 side, the flow rate per unit time to the first to third filter units 310, 320, It can be approximately the same state.

This structure can be applied to both the case where the distribution pipe 611 is provided in the form of a parallel circular tube or the case where the distribution pipe 611 is provided in the form of a tapered circular pipe. By adjusting the diameter of the gas flow hole 612, The second filter unit 320 and the third filter unit 330 provided at positions more distant from the exhaust gas inlet 101 side than the first filter unit 320 and the third filter unit 330 are smoothly flowed so that a uniform amount of exhaust gas .

11, as another example, the gas distribution portion 620 includes a disk-shaped distribution plate 621 provided with a plurality of gas flow holes 622 on the exhaust gas inlet 101 side . The gas flow holes 622 are formed substantially radially with respect to the center of the distribution plate 621 so that the exhaust gas does not enter the inner side of the second case 200 in a concentrated state in any one direction, It is possible to enter into the state of being in the state Therefore, the exhaust gas that has entered the exhaust gas inlet 101 can be substantially uniformly distributed to the first to third filter units 310, 320, and 330 after passing through the plurality of gas flow holes 622, Abnormalities of the units 310, 320, and 330 can be minimized, and the durability can be further increased.

In order to further enhance the gas distribution effect as described above, the plurality of gas flow holes 322, which are disposed in the relatively central region, are arranged in a relatively small area, Respectively.

It is assumed that the gas flow rate per unit time of the front end and the rear end of the distribution plate 621 is the same in the flow direction of the exhaust gas, 622 are smaller than the gas flow rate immediately after passing through the gas flow holes 622 provided in the central region so as to be relatively spaced from the first filter unit 310.
