气体分布方式对带列管内构件的鼓泡塔流动规律的影响
Impact of gas distributor configuration on hydrodynamics in bubble column with pipe internals
摘要
Abstract
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.关键词
