Embodiment 1
[0037] This example provides an enhanced micro-reaction device for preparing micro-nano powder, which is composed of a pipeline and an ultrasonic generator 9, the pipeline has a central channel 13 with a gradually enlarged size, and the ultrasonic generator 9 is arranged in the central channel 13 external. Further, the pipeline is also provided with a circulating fluid channel, which is located outside the central channel and is provided with a water inlet 18 and a water outlet 19 . The circulating fluid channel is divided into two parts 14 and 15, which are connected to each other and arranged symmetrically outside the central channel for the circulating fluid to pass through. The circulating fluid is water to control the reaction temperature. Furthermore, the pipeline is also provided with a sonotrode installation cavity, and the sonotrode installation cavity is located outside the central channel 13; the sonotrode 9 is installed in the sonotrode installation cavity. The s...
