【摘要】 采用30％TBP（煤油）／HAc／水体系研究了脉冲填料萃取塔的流体力学和传质特性，考察了脉冲强度和填料类型对塔性能的影响。实验表明装填QH－1型扁环的脉冲填料萃取塔的性能明显优于装填陶瓷和不锈钢拉西环的脉冲塔。文中给出了装填QH－1型扁环的脉冲填料塔的特性速度和Hoxp的经验计算式。更多还原

【Abstract】 The hydrodynamics and mass transfer of Pulsed Packed Extraction Column (PPEC) havebeen studied using 30%TBP (kerosene)/HAc/H2O system. The effects of pulsation intensity and packingtype on PPEC were investigated. It is clear from the comparison that the characteristic of PPEC filledwith QH-1 has super characteristics than those of ceramic and stainless steel Raschig Rings. Empiricalequations of characteristic velocity and Hoxp for PPEC filled with QH-1 packing were proposed.更多还原
