It is used for simultaneous treatment of SO2, NOx and dust in the sintering flue gas to meet the standard emission of sintering flue gas. After the original system of wet desulfurization and wet electric precipitation of 45-65 ℃ flue gas, in the system under the action of the induced draft fan into the GGH heat exchange to 150-170 ℃, and then with the heating of the combustion of high-temperature flue gas mixing into the high temperature flue gas 180-200 ℃, into the denitration reactor to complete the denitration reaction, denitration of high-temperature clean flue gas through the GGH heat exchange to 75-90 ℃ into the induced draft fan emissions to the chimney and discharged into the atmosphere.
MAIN character:
1.Low-temperature SCR denitrification technology, denitrification efficiency of not less than 90% at 180-200°C
2.Low denitrification temperature, lower system heat dissipation and energy consumption
3.Patented on-line resolution technology for rapid recovery of catalyst activity.
