列管束内构件对鼓泡塔流动发展的影响
Effects of Pipe Bundles on the Sparger Zone Development in Bubble Columns
摘要
Abstract
Bubble column reactors with pipe bundle heat exchangers are of importance in industrial application. Study on the effect of pipe bundles on flow development was conducted in a bubble column of 0.5 m diameter with 40 vertical pipes. Radial distributions of gas hold-up and liquid velocity at different heights were measured with conductivity probe and Pavlov tube respectively. Results show that a fully developed zone is existed in the column with pipe bundles. Comparing with the column without pipes, the size of the sparger zone is remarkably extended from 2 diameter height to 4 diameter height, which accounts for more than 50% of the column volume. The liquid level height has no significant impact on the existence and development of the sparger zone.关键词
