An apparatus having a baffle device and used for treating an exhaust gas, the apparatus comprising: (a) an inlet duct through which the exhaust gas is flowed in, (b) a bend portion, and (c) a catalyst duct connected to the inlet duct through the bend portion and having a catalyst disposed therein and used for purifying the exhaust gas and, the baffle device being a baffle lattice having a height of A and disposed at the inlet of the catalyst duct in the direction of the cross section of the catalyst duct, wherein the baffle lattice is provided, for supporting the lattice, with an outer frame having a height of B and disposed so that the upper ends of the outer frame become the same level with the upper ends of the baffle lattice; the outer frame is provided, on its lower ends for supporting the frame, with beams; and the relation between the height A and the height B satisfies the following equation: <DF>A < B, </DF> in which apparatus, occurrence of channeling (nonuniform flow distribution) of an exhaust gas at the inlet of a catalyst layer can be prevented. <IMAGE> |
