Study On The Intensifying Effect Of Cyclonic Absorber Applied In Absorption Process

A mathematic model of gas-liquid absorption and mass transfer with chemical reaction in a cyclonic absorber has been established according to different dynamical characteristics of the dispersed liquid phases in the swirling flow field based on the species mass-conversation equations in this thesis, witch is consistent with the Danckwerts' Surface Renewal Theory. Not only considering the diffusive term and source term but also the transient and convective term, this model could explain the reaction process in a swirling field much more exactly.And according to this model, the transfer coefficient in liquid side k Lis proportionally to the square root of diffusion coefficient D and the square root of the renewal rate S , which had been proved by experiments approximately. Compared with other absorbers, the experimental results suggested that the cyclonic absorber, as simple and static equipment, could also supply a sound hydromechanical environment to intensify the process of mass transfer. All those work will give a theoretical fundamental for the further research on the application of the high absorption performance of the cyclone, such as desulphurization, air cleaning etc.Moreover, the Computational Fluid Dynamics (CFD) method was tried to simulate the single phase and multiphase flow in the cyclonic absorber and some optimization suggestions were but forward for further research.
