摘　　要：介绍了宝钢气喷旋冲烧结烟气脱硫技术的研发背景和技术特征。利用在线工业试验装置,通过连续运行和正交试验,研究了各种因素对宝钢烧结烟气脱硫工艺脱硫率的影响。结果表明,吸收塔液位、吸收浆液pH值、入塔烟气量、入塔烟温、烟气喷射速度是主要影响因素,在浆液pH值为5.0～5.5、吸收塔液位为4.2～4.3 m、烟气量为4.3万m3/h、气喷速度为20～28 m/s、入塔烟温为65℃工况条件下,脱硫效果最佳。This paper introduced the research background and technical features of Baosteel＇ s swirl-jet-absorbing wet limestone-gypsum sintering FGD technology. By means of industrial online pilot plants, through continuous running and orthogonal tests, the effects of various influencing factors on SO2 removal efficiency of Baosteel FGD were studied carefully. The results indicate that liquid level （H） in the absorber, the slurry pH value, temperature （T） and flow rate （Q） of inlet flue gas, and flue gas jet velocity （V） are the main influencing factors. Furthermore, when pH is between 5.0 and 5.5, H is between 4.2 and 4.3 m, Q is 43 000 m3/h, V is between 20 and 28 m/s, and T is below 65℃, the best desulfurization efficiency can be achieved.
