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 cavitation cloud microbubble preparation device and method thereof, comprising a generating container, a gas nucleus source and an ultrasonic transducer. The generating container is provided with a liquid, the gas nucleus source is arranged in the liquid in the generating container, the radiation surface of the ultrasonic transducer is arranged in the liquid, and ultrasonic waves are transmitted through the liquid, and the gas nucleus source is Cavitation clouds are produced below. Among them, the cavitation cloud is composed of multiple cavitation bubbles. The cavitation continuously moves and expands and contracts under the action of the ultrasonic wave, and the cavitation merges into a larger cavitation when moving to a node. At the nodes, the large cavitation bubbles collapse during the expansion and contraction process, and the microbubbles dissipate outward. The invention breaks the air bubbles through the cavitation cloud to form cavitation bubbles and then forms microbubbles, and screens through the ultrasonic field to peel off large-sized microbubbles to produce a liquid containing extremely small-sized microbubbles, which can be used in medical, biological, chemical, It has important application value in detection, scientific research and other fields.

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 ...
