<P>PROBLEM TO BE SOLVED: To provide an exhaust gas cleaning system capable of sufficiently securing the flow passage of an exhaust gas to which a reducing agent is supplied, even when an outlet is disposed on the cylinder wall of a casing with a flow reversing means. <P>SOLUTION: The upstream side casing 3 of the exhaust gas cleaning system 1 includes an inlet side end wall 8, a flow reverse side end wall 9, and a cylinder wall 10. An outlet 13 is disposed on the cylinder wall 10 between an inlet side end 18 and an outlet side end 19. The inside of the upstream side casing 3 is provided with an oxidation catalyst setting area 15 where an oxidation catalyst 2 is to be set, a reducing agent supply area 16 where a reducing agent is supplied, and a passage area 17 formed by an outer circumference face of the oxidation catalyst 2 and the cylinder wall 10 and communicating the reducing agent supply area 16 and the outlet 13. In the passage area 17, a shield plate 22 that blocks a part of the passage area 17 is disposed, and the shield plate 22 is disposed in an area from the outlet side end 19 to the end of the outlet 13, including at least an area where the outlet 13 is formed in the outer circumference direction of the cylinder wall 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
