Title:
TWO-STAGE CAVITATION GENERATOR FOR ORGANIC WASTEWATER TREATMENT
Document Type and Number:
WIPO Patent Application WO/2023/222140
Kind Code:
A1
Abstract:
The present invention provides a two-stage cavitation generator for organic wastewater treatment. The two-stage cavitation generator comprises a closed impeller, a stator, and a rotor; the closed impeller comprises a front cover plate, blades, and a rear cover plate; and a plurality of blades are uniformly distributed between the front cover plate and the rear cover plate; working surfaces of the blades are arced surfaces, and back surfaces of the blades are partially protruding, causing a flow channel between the back surface of each blade and the working surface of an adjacent blade to be partially narrowed and form a throat structure; the stator and the rotor are arranged at an outlet of the closed impeller, and the stator is located at the outer periphery of the front cover plate and fixed to an inner wall of a volute; the rotor is mounted on the rear cover plate, a gap is present between the stator and the rotor, and blind holes are respectively provided on the stator and the rotor at two sides of the gap and used for secondary cavitation. Two-stage cavitation can be periodically generated in an environment of one unit of atmospheric pressure, the cavitation intensity is markedly improved, a certain conveying capacity is also achieved, and the present invention is highly adaptable and has great value for organic wastewater treatment.
