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, liquid whistles, etc.), but the cavitation intensity of hydraulic cavitation is small. Less efficient, often insufficient for triggering or strengthening of certain physicochemical reactions

Description

technical field [0001] The invention relates to a hydraulic cavitation generating device, in particular to a hydraulic cavitation generating device capable of generating hydraulic cavitation effects in a rotating flow-limiting manner and used for intensifying physical and chemical processes. Background technique [0002] Cavitation is a process in which vapor bubbles are formed in the low-pressure region of the liquid flow field. In some respects, cavitation is similar to boiling. The difference between the two is that boiling is mainly the result of temperature rise, while cavitation is the main cause. is a reduction in pressure. When the internal pressure of the liquid drops below the saturated vapor pressure (not necessarily exactly the same in the strict sense), the bubbles formed by the cavitation process begin to appear and grow, and as time goes on, the bubbles expand, grow, compress and collapse. But this process is explosive, less than six thousandths of a second, ...
