摘要

摘要: 利用管式炉燃烧实验模拟水泥窑炉预分解与钢铁窑炉烧结过程,在900 ℃下开展钢铁尘泥、转炉灰、烧结灰、高炉布袋灰4种典型的钢铁冶炼固废与垃圾焚烧飞灰热利用及共燃过程气相污染物生成特性与排放控制的相关研究,其中,4种钢铁冶炼固废与垃圾焚烧飞灰分别以2∶8、3∶7、4∶6的质量比进行共燃。结果表明:钢铁尘泥、转炉灰、烧结灰、高炉布袋灰分别以20%、20%、30%和40%的比例与垃圾焚烧飞灰共燃,是抑制NO生成、挥发性重金属Pb、Zn挥发的最佳比例。4种钢铁冶炼固废中,转炉灰与垃圾焚烧飞灰共燃对NO生成的抑制效果最好,高炉布袋灰与垃圾焚烧飞灰共燃对Pb挥发的抑制效果最稳定,同时对Zn挥发的抑制效果最佳。该成果可为热处置过程中气体污染物的生成抑制和排放控制技术开发提供参考。

Abstract: The process of cement kiln pre-decomposition and steel kiln sintering was simulated by the tube furnace combustion experiment. At 900 ℃, the formation characteristics of gaseous pollutants were studied during the heat utilization and co-combustion process of four typical steel smelting solid wastes, namely, the steel dust sludge, the converter dust, the sintered dust, and the blast furnace bag dust with the waste incineration fly ash. The co-combustion of four kinds of solid wastes of iron and steel smelting, and fly ash of waste incineration was carried out at the mass ratio of 2:8, 3:7 and 4:6, respectively. The results showed that the best blend ratios of the steel dust sludge, the converter dust, the sintered dust, and the blast furnace bag dust with the waste incineration fly ash to inhibit the formation of NO and the volatilization of Pb and Zn were 20%, 20%, 30%, and 40%, respectively. Among the four typical steel smelting solid wastes, the co-combustion of converter ash and waste incineration fly ash has the best inhibition effect on NO formation, the co-combustion of blast furnace bag ash and waste incineration fly ash has the most stable inhibition effect on Pb volatilization, and the best inhibition effect on Zn volatilization. Above experimental works are expected to be a scientific theoretical reference for the further technological development on the formation inhibition and emission control of gaseous pollutants during thermal disposal processes.
