The working principle of a static mixer is to make the fluid flow in the pipeline and impact various types of plate components, increasing the velocity gradient of laminar flow or forming turbulence. In laminar flow, it is "segmentation position movement reassembly". During turbulence, in addition to the above three situations, the fluid will also generate intense eddies in the direction of the cross-section, with strong shear force applied to the fluid, further dividing and mixing the fluid, The final mixture forms the required emulsion. The reason why it is called a "static" mixer refers to the fact that there are no moving parts in the pipeline, only static components.
The mixing process of a static mixer is carried out by a series of mixing units of different specifications installed in a hollow pipeline. Due to the role of the mixing unit, the fluid rotates left and right at times, constantly changing the direction of the flow mixer. This not only pushes the central fluid towards the periphery, but also pushes the surrounding fluid towards the center, resulting in a good radial mixing effect. At the same time, the rotation of the fluid itself also occurs at the interface of adjacent components, and this perfect radial circulation mixing effect enables the material to achieve uniform mixing. A static mixer is an efficient mixing device without movement, which uses a mixing unit internal component fixed in a pipe to cut, shear, rotate, and remix two or more streams of fluid, achieving good dispersion and sufficient mixing between fluids.
