Abstract:	Stirring blades are the most important part of the reactor. Blades transmit the mechanical energy to the liquid through self-rotation, thus generating high degree turbulences in neighboring areas, and forcing all the liquid to flow inside the tank on a certain route for recycling. This study analyzed the speed deviation and turbulence intensity inside the reactor in case of two or four propeller blades at 45 degree forward, 45 degree backward, or at no deflection angle to explore the impact of different revolving speeds on the flow field inside the reactor. Results suggested that when the blade at positive deflection angle should be applied to generate larger turbulence intensity in the lower flow field to more easily mix relatively weighty particles or quality dispersion.
