[0002] In the process of large-scale dispersion of micro-nano particles and large-scale preparation of micro-nano composite materials in industry, due to the surface energy effect and small size effect of micro-nano particles, the micro-nano particles in the liquid phase composite system are prone to agglomeration, which affects the The dispersion of micro-nano fillers in the matrix and the mass and heat transfer effects of the liquid-phase composite system affect the performance of the finished material

[0003] CN107243310A discloses a kind of supersonic high-oscillating air flow tube reactor, which is provided with an ultrasonic transducer facing outside the tube wall of the vertical reaction tube, and the piston surface of the oscillating device is arranged under the vertical reaction tube to directly contact the reaction material, and at the same time A circular baffle is set in the vertical reaction tube; through the combination of an ultrasonic device and an oscillating device, cavitation bubbles are generated under the action of the ultrasonic wave, and then an oscillating pulse is applied to form an oscillating airflow, which ensures the micro-nano materials in the reactor to a certain extent. Dispersion; but because the arrangement of the ultrasonic transducer is too simple to form a standing wave in the tube, not only the energy consumption is increased but also the ultrasonic vibration effect is not fully exerted; not only that, the ring baffle set in the tube has a blocking effect on the reaction material Too simple, the flow form of the reaction material is single, and there is no obvious help for the dispersion of micro-nano particles

There are still defects in the design of the existing ultrasonic oscillating air flow tube reactor, which leads to poor practical application effect of the reactor and needs further improvement
