中文摘要：

在带列管内构件的鼓泡塔内测量了4种不同布气方式下的气含率和液速径向分布，并与无列管内构件的空塔中的分布进行了比较。结果表明：中心布气条件下气含率与液速的径向分布比空塔更为陡峭；环隙及近壁布气时呈现出环隙高、两边低的马鞍形分布；均匀布气时径向分布较空塔更为平坦。空塔内气体分布器的影响是局部性的，充分发展段在塔内占主要部分；而在列管塔中气体分布器的影响是全局性的，气含率与液速的初始分布决定着其全塔分布。在带列管的大型鼓泡塔中难以观察到充分发展段的存在，因此，气体分布器的设计具有比空塔更为重要的意义。

英文摘要：

Gas holdup and liquid axial velocity profile were measured in a large scale bubble column with tube bundle internals with four different types of gas distributor configuration and were compared with results in the bubble column without internals. Gas distribution type directly determined gas holdup and liquid axial velocity profile in the bubble column with internals. With central distribution, gas holdup and liquid axial velocity profile showed much steeper than those in the bubble column without internals. With annulus or near wall distribution, they presented saddle profile, while with uniform distribution, both of them showed more flat than those in the bubble column without internals. The influence of gas distributor was local in the bubble column without internals and the well-developed region occupied a major part of the column, however, its impact was global in the bubble column with internals and the initial distributions of gas holdup and liquid velocity determined their distributions in the whole column. It was difficult to observe the existence of well-developed region in the bubble column with internals and therefore, designing gas distributor is more meaningful than the bubble column without internals.
