摘　　要：为了解决现有固定床单柱离子交换技术的不足,文章进行钨连续离子交换试验研究。采用转盘式模拟移动床实现了钨连续离子交换,试验中在吸附段和解吸段的进料方式采用下进料,洗钨和洗氯段采用上进料,各段柱子数量依次为3、3、4、2,按照一定流速进料,得到的解吸段高纯液WO_3浓度能达到243.93 g/L,与固定床单柱相比,洗钨洗水量节约55.7%,洗氯洗水量节约44.4%,连续离子交换工艺较现有生产工艺更环保、高效。Experiments on tungsten ion＇s continuous exchange showed that： The feeding mode of the adsorption section adopts the lower feed, and the analytical section is the same. The washing water flows from top to bottom in the wash. The number of ISEP each column were 3, 3, 4 and 2 respectively. At a certain flow rate, the WO3 concentration of the high pure liquid in the desorption section can reach 243.93 g/L. In comparison with the single column, the tungsten wash water and chlorine wash water saved by ISEP system were 55.7 % and 44.4 %. The continuous ion exchange process enjoys advantages of environmentally friendly and high-efficiency.
