<p>PROBLEM TO BE SOLVED: To prevent dioxin from being generated without requiring an organic halogen decomposition catalyst by eliminating the hydrocarbon in a high- temperature exhaust gas being discharged from an incinerator for incinerating the waste including a halogen so that the amount of the hydrocarbon becomes a specific amount or less. SOLUTION: A catalyst is set to the internal side wall of a hydrocarbon elimination tower 3, where the catalyst eliminates hydrocarbon from an exhaust gas being discharged from a compact incinerator 1 for incinerating waste including a halogen so that the amount of the hydrocarbon becomes 1 ppb level or less. In this case, the catalyst should be set to the internal side wall of the hydrocarbon elimination tower 3 while being brought into contact with a high- temperature gas from the incinerator 1 when the gas is allowed to flow from an upper stream to a lower stream inside the hydrocarbon elimination tower 3. A high-temperature gas of 400 deg.C or more that cannot easily generate dioxin being eliminated in the hydrocarbon elimination tower 3 is introduced to a chimney 4, and an exhaust gas 5 is discharged by the chimney 4, thus preventing the dioxin from being generated without requiring an organic halogen decomposition catalyst.</p> |
