塔內件和填料及塔體共同構成了個完整的填料塔，塔內件是填料塔的組成部分。塔內件的作用是為了使氣液在塔內有更好地接觸，以便于發揮填料塔的生產能力和效率，所以說塔內件設計的好壞直接影響到整個填料塔的操作運行和填料性能的發揮。此外，填料塔的”放大效應除了填料本身固有的因素之外，塔內件對它的影響也很大。

Tower internal and tower packing constitute a complete packing tower.Tower internal is one part of tower,and its function is in order to make a better contact in tower,so that could play packing tower's maxmum production capacity adn packing's performance.More over,Packing tower's"amplification effec"in addtion to packing itself's factors,tower internal has bigger impact.
