摘要
本文针对粗锌中金属元素的蒸发行为,选取Cd-Zn、Bi-Zn和Bi-Sn-Zn体系进行了真空蒸馏蒸发动力学实验,测定了合金中组元锌的蒸发速率。用Langmuir公式计算了锌的蒸发速率,结果与实验相吻合,表明了该方法的可行性。计算了三种合金体系中锌的凝结系数,关联了组元活度系数,解释了合金体系中组元间相互作用对元素蒸发速率的影响,研究结果对粗金属真空蒸馏分离提纯及实验设备的优化设计具有指导意义。
Based on the metal elements contained in crude zinc,the evaporation kinetic experiments of the Cd-Zn,Bi-Zn and Bi-Sn-Zn systems in vacuum distillation were carried out.The Langmuir formula was used for theoretical prediction of evaporation rate.The results are in good agreement with the experimental data.It indicates that the method of evaporation rate calculation is applicable.The condensation coefficients of zinc in the alloys were calculated.The relationship between the interaction and the evaporation rate of components in the alloys was discussed.It will be helpful to the separation and purification of crude zinc and the optimization of experimental equipmentby vacuum distillation.
