<p>PROBLEM TO BE SOLVED: To provide a method and device for treating waste gases containing chlorine compd. and sulfur oxide capable of saving manpower and reducing the running cost. SOLUTION: An adsorption device 2 in which a carbonaceous adsorbent is filled and a desorption device 3 in which the carbonaceous adsorbent is discharged and the adsorbent is heated to eliminate adsorbed matter are connected with lines L3 and L4, and the carbonaceous adsorbent is circulated. Moreover, a washing column 41 washing the desorbed gas from the desorption device 3 by spraying washing water is provided. A control device 7 has an estimation part 7a for estimating the adsorbed chlorine distribution in the carbonaceous adsorbent circulated between the adsorption device 2 and the elimination device 3 and estimating the chlorine concn. in the desorbed gas, moreover estimating the chlorine concn. in the washed waste water, and the flow rate is regulated by controlling a flow rate control valve 42 of the washing water on the basis of the estimated result.</p> |
