Embodiment Construction

[0021] Other characteristics, characteristics and advantages of the present invention will be more apparent after the following detailed description of the embodiments of the present invention by way of examples in conjunction with the accompanying drawings.

[0022] figure 1 It is a schematic structural diagram of an ultrasonic cavitation device provided by an embodiment of the present invention. Such as figure 1 As shown, the ultrasonic cavitation device includes: a vibrating body 1 and a reflector 4 , wherein the vibrating body 1 has a radiation surface 2 at one end, and a liquid thin layer 3 is formed between the radiation surface 2 and the reflector 4 . The vibration body 1 is used to convert electric energy into ultrasonic waves, and the ultrasonic waves enter into the liquid thin layer 3 through the radiation surface 2 and form an acoustic field in the liquid thin layer 3 .

[0023] The reflector 4 reflects the ultrasonic waves radiated by the radiating surface 2, and...

Abstract

The invention relates to an ultrasonic cavitation device, which comprises an oscillator and a reflector, wherein a radiation surface is arranged at one end of the oscillator; a thin liquid layer is formed between the radiation surface and the reflector; the oscillator generates ultrasonic waves, which enters the thin liquid layer through the radiation surface; a sound field is formed in the thin liquid layer; the reflector reflects the ultrasonic waves radiated by the radiation surface; the sound field in the thin liquid layer is strengthened through multiple reflection and superposition of the ultrasonic waves by the reflector and the radiation surface, and therefore, the large-area cavitation cloud transversely spread along the thin liquid layer is formed. According to the ultrasonic cavitation device provided by the invention, a reflection surface is arranged on the opposite side of the radiation surface of an energy converter, and therefore, the sound field in the thin liquid layer is strengthened, so that the transversely spread large-area cavitation cloud is formed under low input power.

Description

technical field [0001] The invention relates to the field of ultrasonic cavitation, in particular to an ultrasonic cavitation device. Background technique [0002] Cavitation refers to the formation of cavitation bubbles in the liquid and its subsequent dynamic behavior when the pressure of the liquid drops to a sufficiently low level. Bubbles, these bubbles are generated and collapsed instantly (between a few microseconds to tens of microseconds) according to the cycle of the ultrasonic wave, forming a cloud of bubbles. When these bubbles collapse, high temperature and high pressure will be generated inside the bubbles, and shock waves will be generated in the surrounding liquid. When they are close to the wall, they will move towards the wall and form micro jets hitting the wall. At present, the applications of cavitation, such as ultrasonic cleaning and sonochemistry, are carried out in large water bodies, which not only causes waste of water resources, but also reduces ...
