ANALYSES OF THE INFLUENCING FACTORS OF ROTATING IMPELLER DEGASSING PROCESS AND WATER SIMULATIONEXPERIMENT

On the basis of similarity principle a water- simulative study of the process of rotating impeller degassing (RID) was executed by means of self-made purifying system. The influencing factors on the RID process were studied and laid a theoretical basis for the further development of this kind of technique. The shape of vortex originated in rotating of impeller and its adverse effect on degassing effectiveness were discussed. Meanwhile the influences of shape as well as position of bluff body on degassing efficiency were investigated. The impacts of parameters such as gas feed rate and rotational speed of on degassing efficiency were discussed. The result revealed that the structure and design parameters of impeller are the decisive factors of effectiveness of RID facilities, and the design of the swivel head ought to aim for increasing the additional turbulent shear stress on air bubble and improving the degassing condition.
