摘要/Abstract

摘要： 基于旋转填充床流体流动的可视化结果，建立了超重力旋转填充床气液传质过程的数学模型，模拟氮气解吸水中溶解氧的传质过程。模拟结果表明，缩短液相停留时间、提高液相扩散系数都能增大液相传质分系数k_L；总体积传质系数K_La随超重力因子的增加而增大、随温度的上升而增大、随气相流率的增加略有下降、随液相流率的增加明显增大；空腔区传质贡献率随空腔区的增大而增大，随超重力因子的增大而减小；且短暂的停留时间是超重力旋转填充床对传质过程强化的本质原因。模型较好地符合文献的实验数据，误差在±16%以内。

Abstract: A mathematical model for gas-liquid interphase mass transfer was established based on the visual study of fluid flow in a rotating packed bed (RPB). The effects of model parameters on liquid mass transfer coefficient k_L, as well as the effect of operation parameters on overall volumetric mass transfer coefficient K_La in gas-liquid mass transfer process of water deoxygenation by a nitrogen stream were studied via numerical simulations with the mathematical model. Simulation results indicated that k_L increased with decreasing liquid residence time and increasing liquid molecular diffusivity. K_La increased with increasing higee (high gravity) factor, temperature and liquid flow rate but influenced hardly by pressure, and decreased slightly with increasing gas flow rate. Additionally, the mass transfer contribution of cavity zone diminished with increasing higee factor, as well as decreasing cavity zone volume. According to numerical simulation results, the nature of process intensification for gas-liquid mass transfer process in RPB lay in transient liquid residence time. Deoxygenation efficiency E calculated from this model agreed well with experimental E extracted from literatures with deviations within ±16%, which verified the mass transfer model.
