宋体;letter-spacing:.5pt;mso-font-kerning:0pt">阶梯环是由英国传质公司开发的一种新型开孔型填料。它的高约为直径的一半，一边有锥形翻边，环壁上开有窗孔，并有弯曲叶片伸向环心。由于高度减小及锥形翻边的特殊结构，不但改善了填料层内气液分布，而且增加了气液接触点，有利于液体汇聚分散及膜表面的不断更新，使传质得到强化，分离效率大大提高。

宋体;letter-spacing:.5pt;mso-font-kerning:0pt">一般阶梯环填料较鲍尔环填料的通量可提高10-20％，压降低30-40％，分离效率视具体工艺均有不同程度的提高。到目前为止，全世界已有1000个以上的阶梯环填料塔在吸收、汽蒸和蒸馏等操作中应用。根据具体情况，阶梯环可以代拉西环，鲍尔环，泡罩板，浮阀板和筛板，达到高效，高产以及节能的目的。金属阶梯环的材质可有多种，如碳钢，不锈钢304、304L、410、316、316L等，可供选择。
