Abstract

Abstract

Due to the low grade of domestic iron ore, sintered ore has become an essential raw material in steel production. However, iron ore powder sintering emits a large amount of flue gas containing dust, S, N oxides and other pollutants, which is an important reason for environmental problems such as acid rain, ozone layer leaks, and PM_2.5. These pollutants also pose a serious threat to human health, so proper management is urgently needed. This article introduced the generation mechanisms and current pollution status of several pollutants in sintering flue gas, and summarized the treatment methods and emerging treatment technologies for pollutants. It was found that individual pollutant treatment method could no longer meet the requirements of ultra-low emission of steel enterprises, and collaborative treatment methods also had their own shortcomings. Therefore, enterprises need to consider the characteristics of pollutants, production indicators, emission requirements, and other factors, and choose one or more suitable collaborative treatment processes for flue gas treatment. On this basis, a comprehensive treatment method using new fuel processes, such as coke powder and biomass fuel to reduce flue gas pollutants from the source, and combining it with cooperative treatment methods for pollutants at the end of the process was proposed, in order to realize the whole cycle treatment process of sintering pollutants. This paper could provide a reference for the prevention and control of pollutants in iron and steel industry in China and help the high-quality and green development of iron and steel enterprises.
