摘要
对枝形微混合器在过程强化中的研究工作进行了总结,重点介绍了该微混合器的液-液均相、液-液非均相、以及气-液两相的混合与传质性能。枝形混合器特殊的枝形结构可实现宏观流体的微型化,促进流体的微观混合。枝形结构的几何参数通过Constructal理论确定,可在降低持液量的同时降低流动阻力。研究表明该枝形微混合器具有优良的混合性能、较大的处理量以及较低的阻力损失,在快速液-液反应、气液反应、溶剂萃取、气体吸收、纳米材料制备等化工过程中有重要的应用前景。
This review summarizes the studies of a novel arborescent micromixer for process intensification. This review focuses on the recent advances in the performance of miscible liquids mixing, immiscible liquid mixing, gas-liquid mixing, and in precipitation of barium sulfate. The arboreseent structure, in which the fluids are miniaturized and micromixing is intensified, is determined by minimizing the flow resistence and liquid hold-up according to the constructal approach. The results indicate that the arborescent micromixer has not only excellent mixing performance, but also large throughput and low energy cost. Hence, the arborescent micromixer has great potential in chemical industry.
