• 中文摘要： 為了探討機械式多段氣液攪拌槽各段攪拌翼所需攪拌功率,著者使用了上下隔開之驅動裝置,實驗結果顯示通氣時上,中兩段攪拌翼之氣液分散現象完全不同於最下段之攪拌翼,在最下段攪拌翼達成均勻氣體分散時,上中兩段所吸取之氣體量只及最下段之氣體量之 30-40%,此結果提醒設計此類氣液攪拌槽時必須考慮各段功率消耗之差異。
• 英文摘要： A dual driving mechanism was used to measure gased power consumption of each impeller independently in a triple Rushton turbine impellers agitated vessel system. The results show that the characteristics of each impeller are quite different from each other and the top and middle impellers are easier to attain their recirculation points than the bottom impeller. From the analysis of the measured data, it is also found that the amount of air flowing through the middle and the top impellers are approximately the same and range 30-40% of the gas supplied to the bottom impeller. These results clearly demonstrate that the power consumption by each impeller is quite different and must be taken into account in design of an aerated multi-stage impellers stirred tank.
