超重力旋转床是一种强化化学工业过程的新型反应器,利用高速旋转填料所产生的离心力来模拟超重力环境,液体在高分散、高湍动、强混合以及界面的快速更新下与气相以极大的相对速度在填料的弯曲孔道中进行逆向接触,极大地强化了气液传质过程而不液泛。对影响超重力旋转床气液传质效果的因素,如填料、转子转速以及气/液体流量等进行了综述,并在此基础上,介绍了典型的气液传质理论和近年来国内外对超重力旋转床中气液传质理论及气液传质模型的研究进展,最后对超重力旋转床气液传质的强化技术进行了展望。
Abstract：Rotating packed bed is a kind of new reaction device in industrial chemistry process,used thecentrifugal force generated by materials filling in high speed rotating to imitate the hypergravity enviro-ment,the liquid contacted reversely with the gas phase at high relative velocity in curving hole of packingbed under the conditions of high dispersion,high turbulence,strong mixture and quick renew of inter-face,it strongly intensified the gas-liquid mass transference. Reviewed the influence factors on the effectof gas-liquid mass transference in hypergravity rotating packed bed,introduced the typical theory on gas-liquid mass transference,moreover,introduced recent progress of the theory and the model of gas-liquidtransference in hypergravity rotating packed bed,prospected the intensifying technology in this field.
