外置吹气杯测量折流板脉冲萃取柱柱重压降

Pressure Drop Measurement of Column Weight in Disc and Doughnut Pulsed Extraction Column by External Air Purge Method

摘要: 在内径为0.3 m和高度为5.6 m的折流板脉冲萃取柱中，分别采用内置吹气杯和外置吹气杯对柱重压降信号进行了测量和比较。实验结果表明，两种吹气杯安装方式所测量的结果一致。因此，为了避免由于内置吹气杯所造成的钚纯化循环脉冲萃取柱异形下澄清段的设计和加工难度，推荐可使用外置吹气杯来测量该工段的脉冲萃取柱柱重压降。

Abstract: The pressure drop of column weight was measured in a disc and doughnut pulsed extraction column with the inertial diameter of 0.3 m and height of 5.6 m by internal and external air purge methods, respectively. The experimental results show that the pressure drops of column weight measured by external air purge method are in good agreement with those by internal air purge method, therefore, the external air purge method is recommended to measure the pressure drop of column weight in the pulsed extraction column in plutonium purification cycle.
