<p>PURPOSE:To prevent the surface of looper from sticking of powdered body and to maintain easily of a moving bed type filter, by making the slanted surface of looper, arranged the flow in direction of the gas in parallel at the side where gas is supplied to the moving bed of filler. CONSTITUTION:A waste gas 21 from an incinerator, etc. is introduced together with slaked lime powder 19, to be blown into from a nozzle 10, into an inlet hood 12. The streamline of this gas is blown into a moving ben consisting of filler 2 through between loopers 18, without colliding with the surfaces of loopers, because it is inclined by a slanted pipe 6-C to be almost parallel with the angle to each surface of the looper 18 provided to the front surface of a filter 11. Accordingly, sticking of the powder to the looper surface 18 is restricted to the minimum by the inertial force of mixed dust. The mixed dust contained in the gas flowed into the bed is captured thereby advancing the reaction. Purified gas 23 is discharged through an outlet hood 13.</p> |
