Tubular static mixer is utilizes multiple fixed splitter plates in the pipeline to split the water flow in pairs. At the same time, a cross vortex is generated to reverse the rotation and achieve rapid mixing. There are two types of structure for the rapid mixer. One is to install fixed blades in the raw water inlet pipe, and the other is to diffuse the blades in the pipe by external power. There are three types in China, namely propeller blade mixer, SMM type mixer and ko-max tube static mixer. Among them, komax tube mixer can be divided into paired split flow type, AC mixing type, vortex reaction swirl type Wait. The tubular static mixer has fast and efficient, low-energy pipe spiral mixing.
