box-sizing: border-box;">，空隙率为</span>0.97<span style="font-family: 楷体; box-sizing: border-box;">，由</span>12 <span style="font-family: 楷体; box-sizing: border-box;">个叶片按</span>30<span style="font-family: 楷体; box-sizing: border-box;">&deg;间隔沿径向排布，每个叶片表面均覆盖有不锈钢丝网，气液两相在叶片之间的通道以逆流形式接触。在水脱氧和异丙醇吸收实验中研究了叶片填料旋转床的压降和传质特性，结果显示，其气相压降比传统</span>RPB <span style="font-family: 楷体; box-sizing: border-box;">低。实验中，叶片填料旋转床的等板高度分别为</span> 22<span style="font-family: 楷体; box-sizing: border-box;">～</span>24mm <span style="font-family: 楷体; box-sizing: border-box;">和</span>11<span style="font-family: 楷体; box-sizing: border-box;">～</span>33mm<span style="font-family: 楷体; box-sizing: border-box;">，传质性能稍逊于传统</span>RPB<span style="font-family: 楷体; box-sizing: border-box;">，但相差不大。</span></p></span><p style="text-indent: 32px; box-sizing: border-box;">&nbsp;</p><span style="font-size: 18px;"><p style="text-indent: 32px; box-sizing: border-box;"><span style="font-family: 楷体; box-sizing: border-box;">目前，叶片填料旋转床已被成功应用于挥发性有机污染物的吸收、蒸气中脱除甲醇和正丁醇等分离过程中，为各种溶剂回收过程提供了良好的技术支持。</span></p></span><p style="text-indent: 2em; box-sizing: border-box;">&nbsp;</p><span style="font-size: 18px;"><p style="text-indent: 2em; box-sizing: border-box;"><span style="font-family: 楷体; box-sizing: border-box;">叶片填料旋转床在尽可能不过多影响到传质性能的前提下，降低了设备压降，但是这种降低程度十分有限，未来可以着重从叶片的布置和叶片表面的填料入手对其进一步优化。</span></p></span></section></section></section><section style="   box-sizing: border-box;

box-sizing: border-box;"><span style="font-family: 楷体; box-sizing: border-box;">由于逆流旋转床存在压降大、气液处理量小等缺点，研究人员逐渐把精力转移到错流旋转床上，而多孔波纹板旋转床即属于错流旋转床的一种，具</span><span style="text-indent: 2em; letter-spacing: 0px; line-height: 1.45; font-family: 楷体; box-sizing: border-box;">有动平衡性好、放大效应不明显等优点，其结构如图</span><span style="text-indent: 2em; letter-spacing: 0px; line-height: 1.45; box-sizing: border-box;">3</span><span style="text-indent: 2em;

box-sizing: border-box;"><span style="font-family: 楷体; box-sizing: border-box;">焦纬洲等对多孔波纹板错流旋转床进行了各项深入研究，以空气</span>-<span style="font-family: 楷体; box-sizing: border-box;">水为实验物系，研究了两种板间距填料的流体动力学行为，发现在实验操作范围内其湿床压降为</span>15<span style="font-family: 楷体;

box-sizing: border-box;">还以</span>CO2-NaOH <span style="font-family: 楷体; box-sizing: border-box;">为实验物系，研究了两种板间距填料的传质性能。结果显示，其液相体积传质系数</span>KLae<span style="font-family: 楷体; box-sizing: border-box;">在两种相似操作条件下分别为</span>0.857/s <span style="font-family: 楷体;
