Description

technical field [0001] The invention relates to a variable and controllable cavitator, which belongs to the technical field of fluid reaction devices. Background technique [0002] The hydraulic cavitation phenomenon is that the internal pressure drops when the fluid flows through a restricted flow area (orifice plate, Venturi tube, annulus, etc.). Cavitation bubbles, when the cavitation bubbles flow through the instantaneous expansion channel, the pressure of the liquid rises, and the volume of the cavitation bubbles shrinks sharply until it collapses. At the moment of its collapse, it is accompanied by high temperature, high pressure, strong shock waves and micro jets . The huge instantaneous energy released when the cavitation collapses can destroy the chemical chain and speed up the reaction process. Therefore, hydraulic cavitation is widely used in wastewater treatment, food, and enhanced reaction processes. [0003] At present, researchers at home and abroad generall...

Problems solved by technology

The existing collapse zone still continues the practice of equal-diameter pipes that meet the general flow velocity. The upstream high-speed fluid has not been fully expanded. Collapse barrier, bubbles are not fully collapsed so that the cavitation effect is greatly reduced
