the agitator makes the liquid and gas medium forced convection and homogeneous mixing devices. The type, size and rotational speed of the agitator have an influence on the distribution of the mixing power between the overall flow and the turbulence pulsation. Generally speaking, the power distribution of turbine agitator is favorable for turbulent pulsation, while propeller agitator is favorable for overall flow. For the same type of agitator, in the same condition of power consumption, the large diameter and low rotational speed agitator, the power consumption is mainly consumed in the general flow, which is beneficial to the macro mixing. Small diameter and high speed agitator, the power is mainly consumed by turbulence pulsation, which is conducive to micro mixing. The amplification of the agitator is a complex problem related to the process process, which can only be amplified by step by step, and extrapolated to industrial scale according to the obtained amplification criterion.
