在改进的传质池中通过在线检测草酸浓度,应用瞬时传质系数与平均传质系数,研究了各种方向及组合、不同电压、电极板形状与面积等条件下静电场对体系Cu2+-HDEHP-CCl4/H2O-H2C2O4伴随生成CuC2O4的传质过程特性。外场电压变化、电极面积可改变相间的传质速率,与传质方向成45°夹角的静电场作用对相界面传质速率的影响更为显著,表明相间传质阻力结构或相间传质层具有各向异性。
In the improved mass transfer tank, the concentration of oxalic acid was measured online, and the instantaneous mass transfer coefficient and average mass transfer coefficient were used to study the effect of electrostatic field on Cu2 + -HDEHP in various directions and combinations, different voltage, electrode plate shape and area, Mass Transfer Process of CuCl2O4 with -CCl4 / H2O-H2C2O4. The change of field voltage and electrode area can change the mass transfer rate between phases, and the effect of electrostatic field with 45 ° angle with the mass transfer direction on the mass transfer rate of phase interface is more significant, indicating that the interphase mass transfer resistance structure or interphase mass transfer layer Anisotropy.
