静态混合器是依靠内部特殊的结构单元实现各种流体混合的设备。本文介绍了静态混合器的分类、几何形态、工作原理及影响混合效果的重要参数。在药学领域的应用中,静态混合器可进行混合、乳化、萃取及化学反应等过程,具有混合均一性较好、能耗低的优点,但也存在管道易堵塞、参数复杂、缺乏统一标准等不足。 Static mixer is to rely on the internal special structure unit to achieve a variety of fluid mixing equipment. This article describes the static mixer classification, geometry, working principle and affect the mixing effect of the important parameters. In the field of pharmacy, static mixer can be mixed, emulsified, extraction and chemical reaction process, with the advantages of better mixing uniformity, low energy consumption, but there are also easy to plug the pipeline, the parameters are complex, the lack of uniform standards insufficient.
