For the highly acidic extraction system of zirconium and hafnium, ceramic and PTFE baffles were selected and their hydrodynamic (dispersed phase holdup and droplet diameter) characteristics and mass transfer performance were compared and analyzed. The results show that the PTFE baffle, due to its strong hydrophobicity, is difficult to form droplets, but its holdup is significantly higher than that of the ceramic baffle. At low pulse intensities, the extraction efficiencies of the ceramic baffle and the PTFE baffle are comparable and increase with the increase of pulse intensity. When the pulse intensity increases to 10 mm/s, the ceramic baffle can achieve two theoretical stages of mass transfer, but the extraction rate of the PTFE baffle drops rapidly. By comparing the mass transfer performance of the baffles with that of the traditional Raschig ring packing, it is found that the extraction effect of the ceramic baffle is significantly higher than that of the Raschig ring packing, verifying the applicability of the baffle extraction column. Finally, a prediction model for the dispersed phase holdup, droplet diameter and mass transfer coefficient in the baffle extraction column was established. The research results can provide a theoretical basis for the design of zirconium and hafnium baffle extraction columns.

针对锆铪强酸性萃取体系,优选了陶瓷与四氟材质折流板,对比分析了二者的水力学(分散相持液量、液滴直径)特征与传质性能。结果表明:四氟折流板因具有较强的亲油性,难以形成液滴,但持液量显著高于陶瓷折流板;在低脉冲强度下,陶瓷折流板与四氟折流板的萃取效率相当,并随脉冲强度增大而增大,当脉冲强度增至10 mm/s后,陶瓷折流板具有2个传质理论级,但四氟折流板萃取率迅速下降;将折流板与传统拉西环填料传质性能进行对比发现,陶瓷折流板萃取效果显著高于拉西环填料,验证了折流板萃取塔的适用性,最终建立了折流板萃取塔内分散相持液量、液滴直径及传质系数的预测模型,研究结果可为锆铪折流板萃取塔的设计提供理论依据。

针对锆铪强酸性萃取体系,优选了陶瓷与四氟材质折流板,对比分析了二者的水力学(分散相持液量、液滴直径)特征与传质性能。结果表明:四氟折流板因具有较强的亲油性,难以形成液滴,但持液量显著高于陶瓷折流板;在低脉冲强度下,陶瓷折流板与四氟折流板的萃取效率相当,并随脉冲强度增大而增大,当脉冲强度增至10 mm/s后,陶瓷折流板具有2个传质理论级,但四氟折流板萃取率迅速下降;将折流板与传统拉西环填料传质性能进行对比发现,陶瓷折流板萃取效果显著高于拉西环填料,验证了折流板萃取塔的适用性,最终建立了折流板萃取塔内分散相持液量、液滴直径及传质系数的预测模型,研究结果可为锆铪折流板萃取塔的设计提供理论依据。

For the highly acidic extraction system of zirconium and hafnium, ceramic and PTFE baffles were selected and their hydrodynamic (dispersed phase holdup and droplet diameter) characteristics and mass transfer performance were compared and analyzed. The results show that the PTFE baffle, due to its strong hydrophobicity, is difficult to form droplets, but its holdup is significantly higher than that of the ceramic baffle. At low pulse intensities, the extraction efficiencies of the ceramic baffle and the PTFE baffle are comparable and increase with the increase of pulse intensity. When the pulse intensity increases to 10 mm/s, the ceramic baffle can achieve two theoretical stages of mass transfer, but the extraction rate of the PTFE baffle drops rapidly. By comparing the mass transfer performance of the baffles with that of the traditional Raschig ring packing, it is found that the extraction effect of the ceramic baffle is significantly higher than that of the Raschig ring packing, verifying the applicability of the baffle extraction column. Finally, a prediction model for the dispersed phase holdup, droplet diameter and mass transfer coefficient in the baffle extraction column was established. The research results can provide a theoretical basis for the design of zirconium and hafnium baffle extraction columns.
