PROBLEM TO BE SOLVED: To diminish the pressure drop of a waste gas in a moving bed and to reduce the cost of a moving-bed type waste gas treating device. SOLUTION: This device has a louver 52 on the gas inlet side provided on the upstream side in the waste gas flow direction, a louver 53 on the gas inlet side furnished on the downstream side in the waste gas flow direction and forming a catalyst chamber 51a between it and the louver 52, a catalyst flowing down in the catalyst chamber 51a and forming a moving bed 55 and a rotor rotating-type ejector 58 provided below the louver 52 and discharging the catalyst. The inclination of the side plate formed between the lower end (a) of the louver 52 and the ejector 58 is controlled to <=15 deg.. In this case, the frictional resistance generated between the side plate and catalyst is lowered to a neglible value. |
