<p>PROBLEM TO BE SOLVED: To enhance the utilization efficiency of a solid removing agent to a large extent and to efficiently and economically detoxify a harmful component by bringing gas containing a harmful component into contact with a mixture of the solid removing agent and a solid dehydrating agent capable of absorbing and desorbing moisture. SOLUTION: A solid removing agent A containing copper hydroxide as a reaction main component, a solid dehydrating agent B having moisture adsorbing and desorbing function and a solid removing agent C containing metal oxide as a reaction main component are successively laminated in one column 1 in a laminar state from a gas inlet side. The gas containing a harmful component introduced from a conduit 12 is brought into contact with the respective agents in laminated order and subjected to detoxifying treatment to be discharged from a conduit 13. In this case, moisture generated by the reaction with the solid removing agent A is prevented from exerting adverse effect on the solid removing agent C and the detoxifying treatment of the harmful component can be efficiently and certainly performed. If the solid dehydrating agent B is mixed with the solid removing agents A, C, generated moisture is immediately adsorbed and removed and dehydration efficiency can be more enhanced.</p> |
