the height of agitator is 3 cm, the number of bubbles is the largest, and the effect of
micro-bubble is better.
Application of Water Simulation
According to the exploration of the previous water simulation, it is known that the
optimal bubble refinement conditions are: the shape of agitator is SSB-D, the stirring
speed is 600 r/min, eccentric stirring is 0.4, the inlet gas flow is 0.12 m
3 /h, and the
height of agitator is 3 cm. Under this condition, the average bubble size is distributed
between 0.5 and 3 mm, and the effect of micro-bubble is the best. It also shows that
the gas–liquid contact area increases and the degree of gas–liquid mixing is higher.
It is more conducive to the chemical reaction between gas and liquid.
