Rotary water flow static mixer

The rotating water-flow static mixer resolves the problem that the current static mixer is poor at mixing, which is characterized in that between the top part of the spacing ring (12) and the shell (10) is installed steel plates (2, 5) in alternation; the steel plate (2) at the cross direction has a plurality of holes (11) which are internally installed by the distribution pipes (4). The lower end of the distribution pipe fits close with the curved hole (13) of the steel plate (5). The shell (10) between the steel plates has a water inlet (3). The utility model has a good effect on mixing, which is applied to the static mixing of the heavy viscous polymer and the water.
