塔板作为精馏塔的关键气液接触部件，对精馏塔的性能起着重要的作用。本文对一种新型塔板--全喷淋塔板（TST）的流体力学性能进行了研究。以空气-水为工质，在常压下测试了不同F0下的压降。结果表明，该塔板不会发生液泛现象，具有较大的操作灵活性。此外，TST塔板的压降远低于其它塔板。TST的上述性质将大大有利于扩大生产和降低精馏操作的能耗。
As a critical gas-liquid contact component, trays play an important role in the performance of distillation column. In this paper, the hydrodynamics of a new type of tray, the total spray tray (TST), were investigated. Taking air-water as the working medium, the pressure drop with different F0 was tested under atmospheric pressure. The results indicate that there is no flooding with the tray and thus the wider operation flexibility can be provided by TST. Furthermore, the pressure drop of TST is much lower than that of other trays. The above properties of TST would benefit the production expansion and energy decreasing in distillation operation greatly.
