Abstract:

A mathematical model of the energy consumption for the muhistaged spraying rotating packed bed was presented by theoretical analyses,and was then verified by experiments carried out on a self-developed rotating packed bed by way of measuring the power consumption with an ammeter. Moreover,an equation of the total energy consumption was induced according to the experimental data．The results show that the liquid flux . the rotating speed of the bed,the rotating manner and the structure of the rotors greatly influence the energy consumption,while the gas flux does not.It is also indicated that less friction and better rotating manner can 0bviouslv reduce the total energy consumed by the working rotor.It is finally concluded that the rotating packed bed can greatly enhance the transfer process with less energy consumption.

Key words: rotating packed bed, energy consumption, muhistaged spraying
