| Abstract Scope |
Technical transformation and modification has been carried out on the dense flow absorber for desulfurization of 360m2 sintering machine in Shougang Qian'an Iron and Steel Company. Also, selective catalytic reduction (SCR) denitrification system was added at the same time. Desulfurization efficiency of sintering flue gas was improved by changing the desulfurization agent and expand the capacity of desulfurization system. The desulfurization efficiency increased to over 95%. By applying selective catalytic reduction (SCR) denitrification technology, the nitrogen oxide emission at the outlet is reduced to about 30mg/m3. Through the above technical transformation measures, the sintering process has achieved ultra-low emissions of pollutants. The outlet dust is lower than 10mg/m3, the outlet concentration of SO2 is lower than 35mg/m3, and NOx is lower than 50mg/m3. |
