【摘要】 研究开发了一种矩形垂直筛板。该塔板上设置数个由板孔、升气筒、矩型罩、底隙所构成的矩形帽罩单元,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实验结果证明:矩形垂直筛板具有较低的压降和较小的漏液比,可以在空塔动能因子1.3~3.0 kg1/2/(m1/2.s)、液流强度2.7~21.6 m3/(m.h)范围内正常操作,具有较大的生产处理能力和较宽的稳定操作范围。更多还原

【Abstract】 A kind of rectangular vertical sieve-tray has been developed.This tray is provided with some cover units made up of plate holes,gas riser,rectangular cover and liquid inlet holes.The gas and liquid phase are contacted in spray state in the units to realize two phase heat and mass transfer.The studies on fluid mechanics and mass transfer showed that the pressure drop of this tray was low and liquid leakage was small,therefore,this tray has greater production processing capability and a wider stable operation range.It can operate with kinetic energy factor of 1.3-3.0 kg^1/2/(m^1/2·s¹) in empty column,and in the liquid intensity 2.7-21.6 m³/（m·h）.更多还原
