<p>Disclosed is an exhaust gas purification device, in which a selective reduction catalyst (6) (an exhaust gas purification catalyst) is disposed on the upstream side and a particulate filter (1) is disposed on the downstream side in the middle of an exhaust pipe (10), that is equipped with a burner (2) that generates a high temperature exhaust gas (13) through combustion, an exhaust gas distribution pipe (14) that guides the exhaust gas (13) from said burner (2) to the entry side of both the aforementioned particulate filter (1) and the selective reduction catalyst (6), and valves (15, 16) that are equipped in said exhaust gas distribution pipe (14) and act as a course switching means that selectively sorts the exhaust gas (13) from the aforementioned burner (2) into the entry side of either the particulate filter (1) or the selective reduction catalyst (6).</p> |
