Example Embodiment
[0032] The present invention adopts the following implementation modes in practical applications:
[0033] The sintering flue gas is heated to a suitable temperature by a heater in front of the dust collector and then sent to the denitration reactor. Because the denitration reactor is equipped with a catalyst layer, the catalytic reduction reaction is carried out under the action of the catalyst to remove NOx, and the removal efficiency can reach 80 %~90% or even higher, the sintering flue gas after the reaction is discharged into the atmosphere after dust removal and desulfurization.
[0034] In this embodiment, since the denitrification reactor is arranged in front of the dust collector, energy can be saved, but the amount of iron ore catalyst is larger. Therefore, the denitrification reactor can be designed as a fluidized bed to realize online catalyst replacement.
[0035] Through research, it is found that the CO in the sintering flue gas itself can reduce NOx by 10% to 15% by i...
