Device and method for removing NOx in sintering exhaust gas

The invention provides a device and method for removing NOx in sintering exhaust gas. The device comprises an oxidation catalyst reactor for carrying out oxidation of incompletely burned gas in sintering exhaust gas; a selective catalytic reduction rector, which is the subsequent device of the oxidation catalyst reactor and is used to carry out reduction reactions of NOx; and a reducing agent supply device, which supplies a reducing agent to the selective catalytic reduction rector. The heat discharged by oxidizing the incompletely burned gas is utilized. Even if a conventional auxiliary fuel for the selective catalytic reductive denitration equipment is not used, the NOx can be easily removed, the generation of ammonium sulfite is prevented, and a high catalyst activity is maintained. 本发明提供种氮氧化物去除装置及利用所述装置的氮氧化物去除方法，所述氮氧化物去除装置包括：氧化催化剂反应器，包括在烧结排放气体内的不完全燃烧气体进行氧化反应；选择性催化还原反应器，是所述氧化催化剂反应器的后续装置，氮氧化物进行还原反应；以及还原剂供给装置，向所述选择性催化还原反应器供给还原剂，由此，利用包括在烧结排放气体内的不完全燃烧气体进行氧化而所产生的热，因此即使不使用现有的选择性催化还原脱氮设备所需的辅助燃料也能够在贯的工艺中容易去除氮氧化物，防
