摘　　要：针对大体量含氚水分离净化的需求,自主设计建设了三塔级联水精馏系统,内部装填有自研高性能填料。在中试实验过程中,以5~10 kg/h的处理量,完成了吨量级含氚轻水的分离处理,实现了贫化倍数高于2 000倍、富集倍数高于20倍的分离效果。测得规整填料等板高度为14 cm,散堆填料等板高度为4 cm,运行过程各关键参数稳定,全系统已稳定运行超过900 h,可满足规模化工程放大的要求。Aiming at the demand for separation and purification of tritiated water,a three-column cascade waterdistillation system has been independently designed and constructed,which is filled with self-developed high-performance packing.During the pilot scale experiment,the treatment of ton level tritiated water was completed at theprocessing capacity of 5−10 kg/h.The separation effect has been achieved at the detritiation factor higher than 2000times and the enrichment factor higher than 20 times.The height equivalent to a theoretical plate of regular packing is14 cm,and that of random packing is 4 cm.The key parameters vary in a minuscule range during the operation,andthe entire system has been running stably for more than 900 h,which can meet the requirements of large-scaleengineering application.
