The respected Comrade
"We should make it our major thrust to develop such core, basic technologies as IT, nanotechnology and bioengineering, along with such pivotal and beneficial scientific and technological fields as new materials and energy, space and nuclear technologies, and concentrate our efforts on them."
In the field where the ultrasonic cavity is formed, several purposes can be achieved by using such strong energy as high temperatures above 4,727 K, strong pressure of about 5.05 × 108Pa, strong shock waves and micro-jet flow over 400km/h, which is formed in local space but difficult to achieve in normal conditions in a very short time when the bubble bursts.
The powerful ultrasound processor that can obtain such strong energy, which is difficult to achieve in a conventional way, can be effectively used in the development of new materials with phase transformation technology and advanced technologies such as the massive synthesis of nanomaterial.
To this end, we have developed and fabricated an industrial powerful ultrasonic processor, as a result of a research to scale up the ultrasonic device from a laboratory scale to an industrial scale.
By designing the various parts of the ultrasonic transducer in a new form and realizing multi-stage amplification by a booster and horn consisting of five components separately, the conversion efficiency is improved, the heat rise is limited to a maximum, and the zero voltage zero current switching mode (ZVZCS) is applied to improve the efficiency and stability of the ultrasonic oscillation circuit, thus we established the industrial powerful ultrasound technology.
The developed powerful ultrasonic processor can be operated continuously for 60 min with a maximum power of 1,500W with conversion efficiency of more than 85%. The photograph below shows the processor and how it works.
This processor can be applied to new fields such as ultrafine fragmentation of metal and nonmetal oxide hard particles, nanomaterial synthesis, etc., as well as classical applications of ultrasonic energy such as emulsion, suspension, homogenization, promotion of various chemical reactions, depolymerization, etc.
The details were published in the Springer Publishing House's journal "Journal of vibration engineering and technologies" under the title "A method of optimum design for a high power ultrasonic radiator with ten elements" (https://doi.org/10.1007/s4241 7-020-00264-9).
