<p>PROBLEM TO BE SOLVED: To provide a DPF suction/cleaning device which is capable of efficiently separating and recovering fallen-off fibers sticking to DPF after being broken when the DPF is manufactured using an inorganic fibrous material. SOLUTION: This DPF suction/cleaning device 1 sucks and removes the fallen-off fibers of the broken DPP 10 made up of the inorganic fibrous material. In addition, a blast passage 21 connected to a blast means 3 is linked to one 11 of the sides of the DPF 10, as an inlet and an outlet, which is arranged at a mounting part 2 of the DPF suction/cleaning device 1 and a suction passage 22 connected to a dust collecting means 4 and a suction means 5 is linked to the other side 12 of the DPF 10. Further, separation promoting means 6 and 15 which come closer to or come into contact with a filter body 10a inside the DPF 10 are provided.</p> |
