<p><P>PROBLEM TO BE SOLVED: To provide a device of a simple structure for collecting a solid matter capable of suppressing the deposition of a solid matter in an introduction section of an exhaust gas without decreasing the efficiency in collecting a solid matter. <P>SOLUTION: The device for collecting solid matter includes a container 2 into which the exhaust gas containing solid matter is introduced, a filter disposed in the container 2, and a cooler 5 for cooling the container 2. A gas introduction port is opened in the container 2, and a gas introduction pipe 3 is connected to the gas introduction port. The gas introduction pipe 3 includes an end part 30 connected to the container 2, which end part 30 is made to have a double-pipe structure constituted of an inner pipe 31 and an outer pipe 32. The size C of the gap between the inner pipe 31 and the outer pipe 32 is greater than 2.5 mm and equal to or smaller than 40 mm. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
