Problems solved by technology

Compared with ultrasonic cavitation, hydraulic cavitation has simple equipment and low cost, and can generate large-scale cavitation fields (such as orifice plates, venturi tubes, various whistles, etc.), but the cavitation intensity of hydraulic cavitation is not as good as that of ultrasonic cavitation. Cavitation, often insufficient for some sonochemical reactions

Description

technical field [0001] The invention relates to the technical field of cavitation, and is a comprehensive, comprehensive and complementary hydraulic / ultrasonic coupling cavitation device that is simple in structure, can be used in large-scale production, and can realize cavitation functions. Background technique [0002] Cavitation refers to the formation, development and collapse of voids in a liquid and its subsequent dynamic behavior when the pressure of the liquid drops to a sufficiently low level. [0003] Studies have shown that: in the cavitation field, countless cavities are formed inside the liquid, and when the cavities collapse, instantaneous high temperature and high pressure are generated in the small space inside and around the cavities, and in the liquid around the cavities Form strong shock waves and high-speed micro jets. Therefore, the collapse of the cavitation will be accompanied by extremely complex physical and chemical effects, such as mechanical effe...
