Description
Technical Field
The application relates to the technical field of chemical processes, in particular to a hydrodynamic cavitation generating device.
Background
Hydrodynamic cavitation refers to the process of formation, development and collapse of vapor or gas cavitations within a liquid or at a liquid-solid interface as the local pressure within the liquid decreases. The cavitation effect can make the temperature of gas phase reaction zone reach about 5200K, the effective temperature of liquid phase reaction zone reach about 1900K, and the local pressure is 5.05X 107Pa, temperature change rate as high as 10K/S, strong shock wave and microjet flow at 400 km/h. Cavitation can degrade the performance of mechanical equipment, cause damage such as vibration, noise, cavitation erosion and the like, and cause huge loss and risk. On the other hand, the cavitation can be effectively utilized, and plays a positive role in promoting and strengthening chemical reaction, physical process and the like, thereby achieving the treatment effects of high efficiency, energy conservation, no secondary pollution and the like.
