摘要
本文对塔器许用挠度进行了探讨,说明控制塔器挠度的目的在于控制塔板上液层高度差,当某一块塔板处的塔体挠度使该塔板上液层高度层Δ′值等于该块塔板干板压降h_c的0.5倍时,该块塔板处的塔体挠度,即为该高度处的塔器许用挠度。
In this paper, the allowable flexure of columns is investigated. The purpose of controlling the column flexure is to control the liquid height difference on the tray. When the liquid height difference on a tray equals to half of the pressure drop across that tray without liquid on it, the column flexure at the height where that tray is located is the allowable flexure of the column at that height.
