Dynamic fine bubble membrane diffuser is a new type of aerator, which belongs to fixed installation fine bubble membrane diffuser. It consists of a round cover, a rotary mixing cylinder, a rotary mixing ring, a sleeve joint clamp and a gas distribution pipe.

In the dynamic fine bubble membrane diffuser, the air introduced into the aerator is divided into two parts, one is clockwise and the other is counter-clockwise. Under the action of two different swirling directions, the air-liquid reacts instantaneously and continuously in the rotating mixing cylinder of the sleeve. Reinforced mixing zone. A large number of bubbles produced by swirling and mixing swirling flow are blocked by the dome, and evenly and densely distributed upward to produce bubbles. Generally speaking, the dynamic aerator is composed of macroporous bidirectional rotational mixing, sleeve reinforced rotational mixing and dome blocking diffusion, so that the gas phase collides, shears and splits in the liquid phase, thus forming mixed diffusion. Because the dynamic aerator adopts the large hole exhaust, even after the air stopping and pressure stopping, the sewage will not cause the blockage of the exhaust hole in the aerator and the distribution pipe, thus solving the blockage problem of the aerator fundamentally and keeping the oxygen utilization rate unchanged for a long time. However, because of the larger bubble diameter, the oxygen utilization rate is lower than that of the microporous aerator, generally between 15% and 19%. Similar to the structure and performance of the dynamic aerator, the rotary aerator is also used.
