摘　　要：多溢流塔板广泛应用于大塔径和特大液体负荷的场合。分别采用等鼓泡面积法和等通道长度法对多溢流塔板进行设计,并对2种方法进行了总结比较。结果表明,2种方法都能够保证多溢流塔板各通道气液比相等,但等通道长度法优于等鼓泡面积法。Multi-pass trays are widely used in large-diameter tray columns and high liquid loading applications.Equal flowpath length design and equal bubbling area design,whcih are used to design multi-pass trays,are summaried and compared.The result shows that two methods can make vapor/liquid ratio equal in every pass of four-pass trays,but equal flowpath length design is better.
