Static Mixer is an efficient mixing device without moving parts. Its basic working mechanism is to use the mixed unit fluid body fixed in the tube to change the flow state of the fluid in the tube, so as to achieve the purpose of good dispersion and full mixing between different fluids. The device is widely used and is not detachable.
Structure of the CPVC Static Mixer: usually consists of three parts: shell tube, tube internal mixing unit, and two end flanges (or other connection mode). The casing pipe and flanges at both ends are standard pipe fittings for conventional industry, usually with a nominal diameter of DN15-DN1000. Can be made of stainless steel or carbon steel, can also be made of plastic material, the mixer at both ends can also be straight pipe, can also be thread, clamp, live connection and other connection methods, but also with cold, hot jacket. Mixed units are usually welded in pipes and can be movable under special conditions. Different types of static mixers differ in the internal mixing units, including the number of mixing units, materials, and specifications. The structure of the various types of static mixtures is detailed in the following parameter table.
The working principle of the Plastic Static Mixer: PVC Static Mixer working principle, is to let the fluid flow in the pipeline impact various types of plate elements, increase the fluid laminar motion velocity gradient or form turbulence, laminar is "split-position move-rejoin", turbulence, fluid in addition to the above three cases, will be in the section direction of violent vortex, has a strong shear force on the fluid, make fluid further split mixing, final mixing needed to form the emulsion. What is called a "static" mixer means that there are no moving parts in the pipe, only stationary components. When two or more fluids flow through the inner mixing unit in the tube, they undergo multiple segmentation, shear, rotation and refusion, and it realizes the full mixing between the fluids. The fluid mixing mechanism of PVDF Static Mixer is quite different between laminar flow and turbulence. During laminar flow, static mixers rely on the path of the fluid to divide, shift, and then rejoin. Due to the regular and repeated effect of the three mixing elements of "division, one shift and one reconvergence", the mixing is realized. In turbulence, in addition to the above three elements, the fluid is in the direction of the flow section of the violent vortex, resulting in a strong shear force acting on the fluid, which makes the fine part of the fluid is further divided, and then achieve another mixing.
