The invention provides a supergravity nano-microbubble generating device and a reaction system. In the device, a liquid phase is a continuous phase, and a gas phase is a dispersed phase; gas enters the interior from a hollow shaft, and primary shearing is carried out on the gas through shearing action of aeration micropores for forming bubbles; then the bubbles are quickly separated from the surface of the rotating shaft under the action of the rotating shaft which rotates at a high speed; and secondary shearing is carried out under the strong shearing force of a super-gravity environment generated by the rotating shaft to form nano-microbubbles. The nano-microbubbles have the advantages of being fast and stable and having a small average particle size, the average particle size of the formed nano-microbubbles is in a range of from 800 nm to 50 microns, and the range of the average particle size of the bubbles can be adjusted and controlled by adjusting the rotating speed of the rotating shaft. According to the device, on one hand, the problem that a liquid phase in a conventional supergravity device is discontinuous and a liquid phase containing nano-microbubbles cannot be formedis solved, and on the other hand, the problem that nano-microbubbles are clustered on the surface of a static microporous medium is solved.

The invention provides a supergravity nano-microbubble generating device and a reaction system. In the device, the liquid phase is a continuous phase, and the gas phase is a dispersed phase. The gas enters the interior through a hollow shaft, and the gas is subjected to shearing action by the aeration micropores. The first shearing forms bubbles, and then the bubbles are quickly separated from the surface of the rotating shaft under the action of the high-speed rotating shaft, and are subjected to secondary shearing under the strong shearing force of the supergravity environment formed by the rotating shaft to form nano-micro bubbles, which are fast, stable, and stable. The advantage of the small average particle size is that the average particle size of the formed nano-micro bubbles is between 800 nanometers and 50 microns, and the average particle size of the bubbles can be controlled by adjusting the rotation speed of the rotating shaft. On the one hand, the device overcomes the problem that the liquid phase is discontinuous and cannot form a liquid phase containing nano-micro-bubbles in the traditional hypergravity device, and on the other hand, it overcomes the problem of the aggregation of nano-micro-bubbles on the surface of the static microporous medium.
