Spinning disk reactor (SDR) exhibits excellent performance for liquid-liquid micromixing. For traditional SDR, there is still much room to intensify micromixing efficiency through structure design of disk surface and pre-mixer type. In this work, SDR consisted of a spinning disk and a pre-mixer. Three kinds of baffles on the disk were designed for enhancing disturbance of liquid film. Besides, two types of pre-mixers were adopted in the SDR for improving micromixing environment. The iodide-iodate reaction was employed as working system. Compared with other kinds of baffles, the radial baffle exhibited better micromixing efficiency. The incorporation model was adopted to determine the corresponding micromixing time of SDR with radial baffle which reduced about 60% than that of SDR with smooth disk. Pre-mixer could also enhance the micromixing efficiency of SDR, especially at relatively low rotational speed. Considering different rotational speed requirements, suitable intensification mode was proposed for improving micromixing performance of SDR.

旋转盘反应器 (SDR) 表现出优异的液-液微混合性能。对于传统的SDR，通过盘面和预混器类型的结构设计来提高微混合效率还有很大的空间。在这项工作中，SDR 由一个旋转盘和一个预混合器组成。圆盘上设计了三种挡板，以增强液膜的扰动。此外，SDR 中采用了两种类型的预混器来改善微混合环境。碘化物-碘酸盐反应用作工作体系。与其他类型的挡板相比，径向挡板表现出更好的微混合效率。采用掺入模型确定了径向挡板SDR的相应微混合时间，比光滑盘SDR减少了约60%。预混合器还可以提高 SDR 的微混合效率，尤其是在相对较低的转速下。考虑到不同的转速要求，提出了合适的强化模式以提高SDR的微混合性能。
