REFUSE TREATMENT FACILITY

摘要

PROBLEM TO BE SOLVED: To obtain a refuse treatment facility in which exhaust gas is not discharged directly to the outside of a system even when the facility is started up and adverse effect onto a denitrification catalyst is eliminated. SOLUTION: In an exhaust gas line 4 for discharging exhaust gas generated from an incinerator through a bag filter 7 and a catalyst denitrification reaction column 9, a bag filter bypass line 10 is coupled between the upstream side of the bag filter 7 and the downstream side of the catalyst denitrification reaction column 9. A denitrification bypass line 15 is provided between the outlet part of the bag filter 7 and the intermediate part of the bag filter bypass line 10. When the facility is started up, unstable exhaust gas is passed through the bag filter 7 and discharged while bypassing the catalyst denitrification reaction column 9.
