【摘要】 通过分析板式塔与填料塔各自的优缺点,在梯矩形主体连续传质塔板的基础上,提出一种由喷射型塔板、规整丝网填料及其附件构成的复合塔板.实验考察了操作条件与几何结构等因素对该复合塔板流体力学性能的影响.结果表明与其他板式塔板相比,该塔板在相同的操作条件下具有压降更低、通量更大、操作弹性更高、雾沫夹带更小等优点.更多还原

【Abstract】 Analyzing the advantages and disadvantages of tray column and packing column, a new kind of compound column comprising the spraying LLC-Tray and regular packing was presented.Experiments were conducted to study the effects of operating conditions and geometrical shape on the hydrodynamic performance of the compound column and the results showed that as compared the tray column under the same operating conditions, the compound column possessed such advantages,as lower pressure drop,higher flux, less entrainment and bigger flexibility of operation.更多还原
