倒U型双塔式高效铀吸附试验装置DN400的设计和研发,克服了目前离子交换设备在树脂床层上部易发生板结、树脂磨损大、对泥沙敏感度高、反冲操作无法形成理想的柱塞流的缺陷。该装置与阀门顺序控制、穿流式筛板、独特的进（出）液装置相结合,大大提高了铀的提取效率。

A DN400 experimental facility with inversed U-shaped twin towers for uranium ion exchange is designed and developed to solve the existing problems in ion exchange equipment, such as easy agglomeration on the upper layer of resin bed, much resin abrasion, high sensitiveness for mud and sand, and difficulty in producing ideal plug flow in back-wash process. The facility combined with the valve control principle, cross fl0w type sieve plate and the unique inlet and outlet structures can solve the above problems,and the eff...
