<p><P>PROBLEM TO BE SOLVED: To provide a method for treating an acidic or alkaline toxic gas and an apparatus for the treatment capable of greatly enhancing the life cycle of activated carbon and reducing the maintenance cost thereof, by using particulate activated carbon only, obtaining a high removal efficiency with the same level as in the conventional activated carbon system. <P>SOLUTION: In this method for removing acidic or alkaline components from a toxic gas by passing the acidic or alkaline toxic gas through a particulate activated carbon layer, a chemical solution, which reacts with the acidic or alkaline components to neutralize is intermittently sprayed to the activated carbon layer. Thus, the salt formed by the neutralization reaction is washed together with impurities attached thereto, the acidic or alkaline chemical solution can be attached to the activated carbon layer, and then the activated carbon is regenerated to be reused. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
