Description

Technical Field

[0002] Agitator is a device that forces convection and uniform mixing of liquid and gaseous media. The type, size and speed of the agitator have an impact on the distribution of stirring power between the overall flow and turbulent pulsation. Generally speaking, the power distribution of turbine agitators is beneficial to turbulent pulsation, while that of propeller agitators is beneficial to overall flow. For the same type of agitator, under the condition of the same power consumption, the power of a large-diameter, low-speed agitator is mainly consumed in the overall flow, which is beneficial to macro-mixing. The power of a small-diameter, high-speed agitator is mainly consumed in turbulent pulsation, which is beneficial to micro-mixing.
