The Static Mixers are in-line mixing devices which consist of mixing elements inserted in a length of pipe. The energy for mixing is derived from the pressure loss incurred as the process fluids flow through the mixing element and additional pumping energy is necessary over and above that normally needed for pumping requirements. The number of elements required in any application is dependent on the difficulty of the mixing duty, more elements being necessary for difficult tasks.
Mixers can be supplied as simple plain ended pipe sections, flanged with multiple injectors and sampling points fitted in bends or in square or rectangular section for ducts and open channels. They can be manufactured in a wide range of materials.
In case of two miscible liquids in laminar flow, the main mechanism in a static mixer is flow division. The elements are helical or pseudo-helical and are arranged in a series of alternating left and right hand 180 twists. The elements split the fluids entering in two streams and than rotate them through 180 degrees. The elements are in series in the mixer.
