[0002] Mixing, that is, the process of mass transfer and heat transfer of mixed medium, in the occasion where each type of medium needs to be mixed, mixer is a commonly used mixing unit equipment. According to principle, it can be divided into static mixer and dynamic mixer. Compared with stirring type dynamic mixing equipment, static mixer has no moving parts, and does not rely on rotating stirring mechanical movement to mix fluid, but uses mixing unit arranged inside the equipment to guide the flow of mixed fluid during flow, and then produce self-rotation, shear separation or movement impact, etc., to achieve the effect of mixing. Therefore, the performance of static mixer is mainly determined by the performance of the mixing unit inside it, and the existing static mixer mixing unit, such as SV, SK, SX, SL and SH mixing units listed in JB / T7660, has the following main problems: 1. The mixing process is mainly laminar flow, i.e. the fluid in a certain area still stays in this area after passing through the mixing unit; 2. The mixing effect is poor, i.e. the fluid and the area are not evenly mixed; 3. The mixing pressure drop is large, as the structure of the mixing unit causes the medium to consume a large amount of kinetic energy when flowing through the mixing unit to achieve the mixing effect, which means a large mixing pressure drop. Therefore, in order to solve the above problems, it is the long-term technical demand of the technical personnel in the field to provide a mixing unit that can achieve good mass transfer and heat transfer effect.
