宝塔罩型塔板性能研究

Study on baota cover tray

开发了一种宝塔罩型塔板。该塔板是在塔板上设置数个由板孔、升气筒、塔型罩、进液孔所构成的豆塔罩单元，在单元内气液呈喷射状态接触，实现两相传热传质。流体力学性能和传质性能研究证明：该塔板压降、氧解析效率、漏液等性能与新型垂直筛板相当，但雾沫夹带要比新型垂直筛板低。因而该塔板具有较大的生产处理能力和较宽的稳定操作范围。

Baota cover tray has been developed.This tray is provided with some Baota cover units madeup of plate holes,gas riser,cover and liquid inlet holes,The gas and liquid are contacted in spray statein the units to realize two phase heat and mass transfer.The study on fluid mechanics and rnass trans-fer proves that the pressure drop,oxygen desorption efficiency,liquid leakage,etc.of this tray areequivalent to those of the new type of vertical sieve tray,but the entrainment is lower than that of thenew typo of vertical sieve tray.Therefore,this tray has greater production processing capability andwider stable oporation range.
