As the largest process of producing and emitting such pollutants as energy consumption. Therefore, through the system integration of source reduction and process control technologies of raw (fuel) materials, equipment, processes, operation operations and terminal comprehensive treatment technologies such as dust removal, desulfurization and denitrification, the optimization of ultra-low sintering fume emissions can be achieved. particulate matter, SO₂, NO_x and dioxin in the iron and steel industry, iron ore sintering has a complex flue gas composition, and the flue gas volume, flue gas temperature and pollutant quality concentration fluctuate greatly by the influence of production raw materials and working conditions, which has become the focus and difficulty of implementing ultra-low emission transformation of the flue gas. Based on the system concept, the effects of raw material control and process equipment improvement on the emission of sintering flue gas pollutants are analyzed, while the matching and adaptability between process technologies such as dust removal, desulfurization and denitration are researched to minimize by-product and secondary pollutant emissions and energy consumption. The results show that the combined technology of optimized fuel, fuel pretreatment and fuel pre-granulation can minimize the generation of pollutants; by optimizing the process operation, the coordinated control of pollution and carbon reduction in the sintering process can be realized; in terms of terminal comprehensive treatment, heating the flue gas and configuring the flue gas exchanger can make full use of the waste heat in the fume and reduce
