摘要: 通过空气氧化亚硫酸钠水溶液验证了单气泡有效利用率的参数关系,实验结果与理论计算符合较好;利用气泡有效利用率对化学法和物理法测量气液间传质系数的差别进行修正.以鼓泡塔为例用气泡有效利用率修正了鼓泡塔反应器模型,讨论了气泡有效利用率在反应器设计中的应用.

Abstract: Based on the oxidation of a air-Na_2SO_3 aqueous system,the bubble effectiveness is investigated experimentally.The experimental data agree well with the calculated results.The application of η is also studied.It may be used to modify the deviation of the k_Lα measured by physical and chemical methods,and the design model of the bubble column,etc.
