摘　　要：在泥磷烟气脱硫技术的实验研究之上,从双膜理论的气液传质动力学角度进行分析,根据泥磷吸收SO_(2)的特性,在不同的反应温度(298.15~343.15 K)下,分别计算了SO_(2)的气液传质系数、总传质系数、气液传质阻力等动力学参数。计算结果表明:SO_(2)气相传质系数和总传质阻力相等,说明实验过程为气膜控制的过程,在反应温度区间内,SO_(2)的气液传质系数都随温度的升高而升高,但SO_(2)的气相传质系数在343.15K时降低。Based on the experimental research of sludge phosphorus flue gas desulfurization technology,the analysis was carried out from the gas-liquid mass transfer kinetics of the double membrane theory.According to the characteristics of SO_(2) absorption by mud phosphorus,the kinetic parameters of SO_(2) mass transfer coefficient,total mass transfer resistance and other kinetic parameters in gas and liquid phase were respectively counted under different reaction temperatures(298.15~343.15 K).In the kinetic investigation,according to the calculation results,the SO_(2)gas-phase mass transfer coefficient and the total mass transfer resistance were equal,indicating that the experimental process was a process controlled by gas film.Within the reaction temperature region,the gas-liquid mass transfer coefficient of SO_(2) increased with the increasing of temperature,but the gas-phase mass transfer coefficient of SO_(2)decreased at 343.15 K.
