ABSTRACT:
A mixer-injector to improve the mixing and solution of treatment substances into a water stream. The mixer-injector has a constricting portion, a cylindrical injection portion, and an expanding portion in that order in the direction of flow, with an injector port entering the injection portion. The twisting vanes are formed on the wall of the constricting portion, and straightening vanes are formed on the wall of the expanding portion. The twisting vanes give a rotary component of motion to an outer portion of the water stream in the injection portion, and the straightening vanes remove at least some of it in the expanding portion, both to cause more pronounced vigorous movement of bubbles, and improved solution of the treatment substances.
