小型环隙式离心萃取器的水力学和传质研究

  • 摘要: 用单级=10mm小型环隙式离心萃取器研究了水-30%TRPO-煤油体系在不同条件下的水力学特性和硝酸、Fe3+和Nd3+的传质特性。在转速4000—4500r/min、流量<600mL/h、相比(o/a)1/10—10/1情况下,硝酸和Nd3+的传质级效率比较高,为90%左右。由于Fe3+的萃取动力学速率比较慢,因此其萃取级效率比较低。
    Abstract: STUDY ON THE PERFORMANCE OF THE HYDRAULIC AND MASSTRANSFER WITH MINIATURE CENTRIFUGAL CONTACTORWang Jiangchen Tang Wencheng Fan Shilei Lian Jun(Institute of Nuclear Energy Technology,Tsinghua University,P.O.Box1021,Beijing 102201)ABSTRACTThe hydraulic performance and the masstransfer properties of HNO3、Fe3+、Nd3+are studied in H2O30%TRPOkerosene system at different conditions with singlestage φ=10 mm miniature centrifugal contactor.The rotor′s speed varies from 4000 r/min to 4500 r/min.The total throughput is less than 600 mL/h.The phase ratio(o/a) changes from 1/10 to 10/1.Under the above experimental conditions,the single contactor operats very well and gives good performance.The stage efficiencies of HNO3 and Nd3+ are about 90%.The Fe3+ extraction is very slow kinetically and the stage efficiency of Fe3+ is low.Key words Miniature centrifugal contactor Fe3+ Nd3+ Hydraulic masstransfer Extraction kinetics
