离心萃取器具有传质效率高、能较好地解决溶剂辐照降解和核临界安全问题等优点。离心萃取器的最大处理能力受转子转速、总流量、流比和重相堰直径等操作条件的影响。φ20mm离心萃取器最大处理流量较大,为将其应用于Purex流程2A段的实验研究中,固定其重相堰直径为10.8mm,用30%TBP/煤油-HNO3体系研究了两相流比(水相﹕有机相)分别为1﹕1和5﹕1时不同流量下
Centrifugal extractor with mass transfer efficiency, can better solve the solvent radiation degradation and nuclear criticality safety issues. The maximum capacity of a centrifugal extractor is affected by operating conditions such as rotor speed, total flow, flow ratio, and heavy-phase weir diameter. In order to apply it to the experimental study of section 2A of Purex process, the diameter of the heavy-phase weir was fixed to 10.8mm. The flow rate of the two-phase flow was studied by a 30% TBP / kerosene-HNO3 system Water phase: organic phase) at 1: 1 and 5: 1, respectively
