preparation example Construction

[0034] In a method for preparing cavitation cloud microbubbles, the steps include the following steps:

[0035] Step 1, setting liquid in the generating container;

[0036]The type of liquid can be arbitrary, it can be organic or inorganic, etc. Generally, different liquids need to be added according to different chemical reactions.

[0037] Step 2, setting the ultrasonic transducer at a position in contact with the liquid surface;

[0038] The radiating surface of the ultrasonic transducer is set in the generating container, and the radiating surface is completely immersed in the liquid, so that the ultrasonic wave is transmitted through the liquid.

[0039] Step 3, setting the gas-entry nuclear source in the liquid of the generating container;

[0040] The liquid also includes a gas nucleus source, which generates cavitation clouds under the action of ultrasonic waves. In a specific embodiment of the present invention, the gas nucleus source is artificially implanted into...

Abstract

The invention relates to a cavitating cloud micro bubble preparing device and method. The cavitating cloud micro bubble preparing device comprises a generating container, a gas nuclear source and an ultrasonic transducer, wherein liquid is contained in the generating container; the gas nuclear source is arranged in the liquid of the generating container; the radiation surface of the ultrasonic transducer is arranged in the liquid; ultrasonic waves are transmitted through the liquid; the gas nuclear source generates cavitating cloud under the effect of the ultrasonic waves, wherein the cavitating cloud consists of a plurality of hollow bubbles; the hollow bubbles continuously move, expand and retract under the effect of the ultrasonic waves; the hollow bubbles are merged into greater hollow bubbles when moving to nodes; the large hollow bubbles collapse and perish at the node part in the expansion and retraction process; micro bubbles are outwards scattered. Through the cavitating cloud, the air bubbles are broken to form the hollow bubbles; further, the micro bubbles are formed; the screening is performed through an ultrasonic field; large-dimension micro bubbles are peeled out; liquid containing ultra-small-dimension micro bubbles is generated; important application value is realized in the fields of medicine care, biology, chemical engineering, detection, scientific research and the like.

Description

technical field [0001] The invention relates to the technical field of cavitation bubble preparation, in particular to a cavitation cloud microbubble preparation device and a method thereof. Background technique [0002] With the advancement of technology, microbubbles are needed in various industries including medical treatment. There are many methods for the preparation of microbubbles, including four main methods for preparing microbubbles: bubble burst method, ultrasonic method, microfluidic method, and dissolved gas method. [0003] Bubble bursting method: Generally, it is a method of breaking the bubbles into smaller microbubbles by using the shear force or pressure gradient of the fluid; [0004] Ultrasonic method: It is a method that uses ultrasonic waves to act on bubbles or gas outlets to generate microbubbles; [0005] Microfluidic method: it is a method of generating bubbles by means of microchannels; [0006] Dissolved gas method: It is a method in which the ...
