Problems solved by technology

At this time, the increased sound energy cannot be effectively input into the liquid and causes cavitation in a wide range of the liquid.
[0005] Therefore, simply increasing the power and simply "amplifying" the existing sound processing device and its sound power may not be able to obtain the desired results
In addition, the input of very large sound power and the high-power electro-acoustic transducer equipment are costly, difficult to maintain, and not conducive to energy saving

Embodiment Construction

[0013] In laboratory experiments, in small-scale experiments, people use sound waves to produce a sufficient amount of sound cavitation in liquids, and obtain more obvious sound treatment effects. But when conducting large-scale experiments, people often use the sound source method used in small-scale, simply increase the sound power, increase the liquid flow, and finally find that this simple method of amplifying the sound power cannot achieve a proportional effect. Amplified cavitation effect.

[0014] Under the premise that this line of thinking is limited by the existing acoustic technology, this proposal considers another approach, that is, starting from the mechanism of acoustic treatment to solve this problem. In general, sound is not the main direct action mechanism for sound treatment in liquids, but only an indirect means, and acoustic cavitation is the mechanism of sound treatment. Then it should and is possible to "smartly" use the characteristics of the sound fie...

Abstract

The embodiment of the invention provides an acoustic cavitation device. The device comprises a container used for holding liquid; two piezoelectric transducer sound sources oppositely arranged on one straight line in the axial direction; and a sound source generator used for adjusting the frequency, position and one or a plurality of parameters in the phase of the sound source. The embodiment of the invention generates strong cavitation in the extensive region away from the surface of the sound source and generates no cavitation in the region of the surface of the sound source so as to realize the control on the acoustic cavitation spatial distribution. The invention solves the problem that the current acoustic cavitation is mainly generated on the surface of the sound source and cannot be generated in mass scale liquid.

Description

technical field [0001] The invention relates to the field of acoustic cavitation, in particular to an acoustic cavitation device. Background technique [0002] Chemists have found in their research that when an acoustic field is applied to a solution that produces a chemical reaction, an increase in the rate of the chemical reaction, an increase in the production of chemical products, a decrease in the conditions of the chemical reaction, and even new chemical products can be measured. It is precisely because of the extraordinary performance of ultrasound in the treatment of liquids in a large field and in the laboratory that an independent branch of science has flourished, called sonochemistry. Sonochemistry and sound treatment occupy a very important position in ultrasonics, and have been applied to quite a few fields so far, such as food, nanomaterial synthesis, pharmaceuticals, chemistry, etc. [0003] However, the tens of thousands of scientific research results obtain...
