Notes:
On the basis of similarity principle a water-simulative study of the process of rotatingimpeller degassing (RID) was executed by means of self-made purifying system. The influencingfactors on the RID process were studied and laid a theoretical basis for the further development ofthis kind of technique. The shape of vortex originated in rotating of impeller and its adverse effecton degassing effectiveness were discussed. Meanwhile the influences of shape as well as position ofbluff body on degassing efficiency were investigated. The impacts of parameters such as gas feedrate and rotational speed of on degassing efficiency were discussed. The result revealed that thestructure 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 onair bubble and improving the degassing condition
