AI Technical Summary
Traditional reactors suffer from problems such as secondary particle agglomeration, uneven flow field distribution, inability to adapt to pH value control, and insufficient transducer life under conditions of high solid content and high viscosity, which cannot meet the needs of continuous industrial production.
A rotating ultrasonic disk, an annular support, a flow guide tube, and an online monitoring device are installed inside the reactor. Through the synergistic effect of the rotating ultrasonic disk and the flow guide tube, a cavitation field is formed throughout the reactor. The wear resistance and corrosion resistance are enhanced by the boron nitride coating and stainless steel structure. The ultrasonic parameters are adjusted in real time by the online monitoring device.
It achieves uniform particle dispersion, improves dispersion efficiency, extends equipment life, ensures product sphericity and batch consistency, and meets the needs of industrial continuous production.
