Agitator is a device for forcing convection and uniform mixing of liquid and gas medium. Type, size and speed of stirrer, counter stirrer
The mixing power has an effect on the distribution between the overall flow and turbulent pulsation. In general, the power distribution of turbine agitators is favorable for turbulent pulsation, while rotor agitators are favorable for overall flow. For agitators of the same type as -., under the same power consumption conditions, the power of the agitator with large diameter and low speed is mainly consumed in the overall flow, which is conducive to macro mixing. The power of small diameter and high speed agitator is mainly consumed by turbulent pulsation, which is favorable for micro mixing. The amplification of agitator is a complex problem related to the process, so far only through the step by step experience amplification, according to the obtained amplification criterion, extrapolation to the industrial scale. The stirred viscosity of different media viscosity refers to the resistance capacity of the fluid to flow, which is defined as: when the liquid flows at the speed of 1cm/s, the shear stress required per 1cm2 plane, known as the dynamic viscosity, Pa? S is the unit. Viscosity is a property of a fluid.
