  • Two-stage cavitation generator for organic wastewater treatment
    Patent number: 12228139
    Abstract: The present disclosure provides a two-stage cavitation generator for organic wastewater treatment, including a shrouded impeller, a stator, and a rotor. The shrouded impeller includes a front cover plate, blades, and a rear cover plate. Several blades are evenly distributed between the front cover plate and the rear cover plate. A working surface of the blade is an arc surface, and a back of the blade protrudes locally, so that a flow channel between the back of the blade and a working surface of its adjacent blade is narrowed locally, forming a throat structure. An outlet of the shrouded impeller is provided with the stator and the rotor, and the stator is located at an outer edge of the front cover plate and fixed on an inner wall of a volute. The rotor is mounted on the rear cover plate.
