| 摘 要： | 在一个6．36L的气升式内环流反应器中，以空气-NaCl水溶液-K树脂为实验体系，在导流筒内的表观气速为1．21～7．28cm·s^-1时，考察了平均气含率、平均固含率随表观气速的变化规律，研究了转向面积比、NaCl水溶液浓度与平均气含率之间的关系。在均匀鼓泡流区域用模型方程Eg=aUgb来关联平均气含率，其中模型参数6=0．766，a与转向面积比、NaCl水溶液浓度关系为a=3．45×10^-5＋0．0146（Sb／Sr）0．0185＋1．35W。

| Abstract: | The effect of superficial gas velocity on average gas holdup and average solid holdup were investigated for the system of air-NaCl solution-K resin in a 6.36 L internal airlift loop reactor.The range of superficial gas velocity is 1.21～7.28 cm·s-1.The effects of area ratio steering and concentration of NaCl solution on average gas holdup were investigated.The corelations are proposed estimating average gas holdup in uniform bubble flow area,b=0.766 and corelated coefficient with area ratio steering and concentration of NaCl solution a=-3.45×10-5+0.0146(Sb/Sr)0.0185+1.35W. |
