| 摘 要： | 液体循环流动是多级鼓泡塔重要流体力学特征之一,文中在内径为282 mm,高2000 mm的鼓泡塔内,采用不同类型的筛板将普通鼓泡塔分割成双级气液鼓泡塔.采用Pavlov管测液速的方法考察了不同筛板、不同表观气速下该鼓泡塔中上下二侧的液体速度分布.根据实验结果得出了液体速度在塔中心处最大,且与表观气速有关,随着表观气速的...

| Abstract: | The characteristic of liquid circulation flow is an important feature of hydrodynamics in multi-stage bubble columns.A bubble column of 282 mm in diameter and 2 000 mm in height was selected,and various kinds of sieve plates were introduced to divide a conventional gas-liquid column into a two-stage gas-liquid bubble column.The effects of sieve plate and superficial gas velocity on the liquid velocity distribution in the upper and the lower of the multi-stage gas-liquid bubble column were studied by the met... |
