  • 摘要: 针对开发的新型静态螺旋切割强化湿法烟气脱硫技术，根据双膜理论从动力学角度建立了静态螺旋切割强化Ca(OH)2溶液吸收烟气SO2的动力学模型，并采用单因素实验探究了烟气SO2浓度、烟气流量、脱硫剂浓度以及脱硫剂循环流量对传质速率的影响。结果表明：模型能较好地描述静态螺旋切割强化湿法烟气脱硫的实际过程，理论计算与实验数据都发现，烟气SO2浓度、烟气流量、脱硫剂浓度以及脱硫剂循环流量的增加均有助于提高传质速率；但当脱硫剂浓度大于5%时，传质速率随脱硫剂浓度的增加改变不大。
    Abstract: For a newly developed wet flue gas desulfurization technology enhanced by static spiral cutting, a kinetic SO2 absorption model from flue gas by Ca(OH)2 solution enhanced by static spiral cutting was established based on the double membrane theory, and a series of single factor experiments were conducted to explore the effects of flue gas SO2 concentration and flow rate, desulfurizer concentration and circulation flow rate on mass transfer rate. The results show that this kinetic model could describe the actual process of wet flue gas desulfurization enhanced by static spiral cutting well. Both theoretical calculations and experimental data indicated that the increase of flue gas SO2 concentration and flow rate, desulfurizer concentration and circulation flow rate was conducive to mass transfer rate improvement. However, mass transfer rate showed slight change with the increase of desulfurizer concentration at the desulfurizer concentrations greater than 5%. This research could provide a basis for the development of a new wet flue gas desulfurization system based on spiral cutting reinforcement.
