传质过程中的界面湍动现象广泛存在,宏观上表现为传质阻力下降,传质速率增加。
The effect of interfacial turbulence on the mass transfer rate in physical absorption processes was investigated quantitatively.
讨论了界面吸附、脱附与扩散对传质阻力的不同影响,建立了薄膜传质的串联阻力模型。
The different effects of external sorption, adsorption and diffusion on mass transfer resistance are discussed and the resistance model of membrane mass transfer was built.
研究结果表明:外扩散过程是传质的控制步骤,增大风速、减小吸附剂颗粒直径是减少传质阻力的有效措施。
The results show: external diffusion is control process for mass transfer, and increasing air velocity and decreasing particle diameter are effective measures to decrease mass transfer resistance.
