一个一个维的不稳定的异构的平行集体转移(ODUHPMT ) 模型被驱散的微滴为不稳定的有机化合物(VOC ) 的吸收改进开发。改进因素的一个分析解决方案基于表面更新理论和 Laplace 域转变被获得。进以有增加的微 dodecane 微滴的不同激动人心的速度的水的丙烷的吸收率在一辆温度调节装置的搅动的坦克试验性地被调查。越过煤气液体的接口和改进因素的集体转移流动被测量。结果证明 dodecane 在丙烷吸收上有明显的改进效果进水,最大的改进因素到达了 11。改进因素与增加 dodecane 体积部分增加了并且与增加激动人心的速度减少了。实验数据与预言和 ODUHPMT 的显示出的高预言精确性建模的模型一起同意了很好。
A one-dimensional unsteady heterogeneous parallel mass transfer(ODUHPMT) model was developed for the absorption enhancement of volatile organic compounds(VOC) by the dispersed droplets.An analytical solution for enhancement factor was obtained based on surface renewal theory and the Laplace domain transformation. The absorption rate of propane into water at different stirring speeds with the added micro dodecane droplets was investigated experimentally in a thermostatic stirred tank.The mass transfer flux across the gas-liquid interface and the enhancement factor were measured.The results showed that the dodecane has an obvious enhancement effect on propane absorption into water,the maximum enhancement factor reached 11.The enhancement factor increased with increasing dodecane volume fraction and decreased with increasing stirring speed.The experiment data agreed well with the model predictions and showed high prediction accuracy of ODUHPMT model.
