摘　　要：考察了文题所述塔的操作特征及隔板高度对其影响。为了提高此种塔的流通能力,作者引入温和的脉冲,并对此改进塔的特性进行了研究,比较了改进前后的塔的性能。作者发现,引入温和脉冲后塔的流通能力可增加一倍以上,各种操作性能也较好。可以认为,脉冲闭式涡轮搅拌萃取塔是一种性能优良的萃取塔。The operation characteristics of a Kuhni column and the effect of compartment height on the behaviour of the column were investigated. In order to increase the throughput of the Kuhni column, a mild pulsation was introduced in the operation, and the behaviour of the pulsed Kuhni column (PKC) was studied. It was found that the throughput is increased by a factor of 2 after the introduction of the pulsation. The operational performance of the PKC is better than the normal one. It is suggested that the PKC can be used as an improved extraction column.
