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 sintering flue gas enters the desulfurization tower and dust removal system to complete the desulfurization and dust removal, the flue gas of 75-100℃ enters the GGH under the action of the system induced draft fan to exchange heat to 150-170℃, and then mixes with the heated and burned high-temperature flue gas to form the high-temperature flue gas of 180-200℃, and then enters the denitration reactor to complete the denitration reaction, and then the high-temperature clean flue gas after denitration passes through the GGH again to exchange heat to 105-130 After denitrification, the high temperature clean flue gas will be heat exchanged by GGH to 105-130℃, and then discharged into the chimney by induced draft fan and into the atmosphere.
MAIN character:
1.Wet desulfurization + wet electric dust removal + GGH heat exchange + hot blast furnace heating + low temperature SCR denitrification + GGH heat exchange + induced draft fan.
2.Semi-dry and low-temperature SCR denitrification technology, with desulfurization and denitrification efficiency of not less than 90%.
3.Front-end semi-dry desulfurization and dedusting reduces impact on subsequent catalysts.
4.Low denitrification temperature, lower system heat dissipation and energy consumption.
5.Patented on-line resolution technology for rapid recovery of catalyst activity.
