<p>A waste gas treating device comprising a flow regulating assembly constructed such that an inlet duct having an inflow of waste gas and a catalyst duct having a waste gas cleaning catalyst disposed therein are connected at a bend, and having a plurality of flow regulating plates arranged in the direction of cross-section of the catalyst duct inlet port, characterized in that the height of the flow regulating plates on the waste gas inlet duct side of the flow regulating assembly is gradually increased toward the end of the bend side so that the flow rate distribution of waste gas in the direction of the catalyst duct cross-section of the waste gas outlet port of the flow regulating assembly is uniform. In the flow regulating assembly installed at the inlet port of the catalyst duct having a catalyst layer therein, nonuniformity of flow rate distribution (drift current) due to the inertial force of waste gas is prevented, increasing the waste gas treating efficiency in the catalyst layer and improving the catalyst life.</p> |
