(57) [Summary] [PROBLEMS] To be able to decompose various toxic gases including dioxin, and to use a catalyst packed bed cassette which has excellent durability, can be used for a long time, and has a compact catalyst packing. The size of the entire dioxin removal device is reduced by using a layer cassette. SOLUTION: Exhaust gas discharged from an incinerator 1 is cooled, and the cooled exhaust gas is Hcl sprayed and sprayed. System, a toxic gas such as a Nox system or a Sox system is removed by a neutralization reaction together with soot and dust, and then the soot and mist are removed by spraying cooling water. The metal-based particulate catalyst 23 is passed through the catalyst-packed layer 19 to decompose and remove dioxins caused by the ionic effect and the radical corona state of the catalytic reaction. |
