| description | The invention discloses a method and a system for reducing emission of carbon monoxide in sintering flue gas. The method comprises the following steps: taking a part of flue gas discharged by a sintering machine as circulating flue gas for oxygen supplementation, and blowing the flue gas into the sintering machine again for cyclic utilization; the other part of flue gas is taken as flue gas to be subjected to emission reduction, enters the first section of the circular cooler and is in contact with a material layer of the first section of the circular cooler, and the flue gas to be subjected to emission reduction is oxidized into carbon dioxide, so that emission reduction flue gas is obtained; all emission reduction flue gas enters the main flue and is discharged after being purified. The system mainly comprises a structure for realizing the method. The method and the system can effectively reduce the concentration of carbon monoxide in the sintering flue gas and reduce the load of a flue purification treatme |
