摘　　要：采用乙醇-水体系对新型折流式超重力旋转床进行了传质性能实验,考察了气相动能因子(F因子)、转子转速对新型折流式超重力旋转床的压降和传质性能的影响。实验结果表明,新型折流式超重力旋转床的压降随F因子、转子转速的增大而增大;每米理论板数随转子转速的增大而增大,随F因子的增大先增大后略有降低;与有液体分布器时相比,无液体分布器时新型折流式超重力旋转床的传质效果更好;与折流式超重力旋转床相比,新型折流式超重力旋转床的压降降低约70%,每米理论板数降低约40%,转子轴功率降低10%～30%。The mass transfer performance of a novel higee rotating zigzag bed（nRZB） in an ethanol-water system was studied. The effects of F-factor and the rotor speed on the pressure drop and mass transfer performance of nRZB were investigated. The results showed that the pressure drop of nRZB increased with the increases of the F-factor and rotor speed. The average theoretical plate number per meter increased with the increase of the rotor speed, and increased firstly and then dropped slightly with the increase of the F-factor. nRZB without liquid distributor was more beneficial to the mass transfer than that with liquid distributor. Compared to the rotating zigzag bed, the pressure drop, average theoretical plate number per meter and shaft power of nRZB reduced by about 70%, 40% and 10%-30%, respectively.
