| 摘 要： | 在一直径为70mm，高为2630mm的有机玻璃纤维液膜萃取分离器冷态实验装置上考察了操作参数及结构参数对其传质性能和流动特征的影响。通过考察体积传质系数，确定了纤维液膜萃取分离器的最佳填充密度和最佳流量比。建立了流动模型，提出了以无量纲准则数雷诺数为设计纤维液膜萃取分离器的准则。实验结果表明，其最佳填充密度为2．8％～3％，最佳操作流量比为5。

| Abstract: | The performances of the fiber film extractor were investigated using a cold plexiglass pipe of 70 mm in diameter and 2 630 mm in height, The influences of the operating and structural parameters on the flow and mass-transfer characteristics of the fiber film extractor were revealed. By analyzing the volume mass-transfer coefficient, the optimal operating flow-ratio and packed density were obtained. A flow model was built. Moreover, based on the theoretical analysis, Renault number was proposed as the design principle dimensionless number for fiber film extractor design purpose. The experimental results indicate that the optimal operating flow-ratio for a fiber film extractor is 5 while the best packed density is 2.8% - 3%. |
