The working principle of ultrasonic sonochemical equipment

What is ultrasonic sonochemistry? Ultrasound technology as a physical means and tools, it can produce a series of nearly extreme conditions in the chemical reaction of various media, this energy can not only stimulate or promote a variety of chemical reactions, and can speed up the chemical reaction Speed can even change the direction of certain chemical reactions, producing some unexpected effects.

At present, ultrasonic sonochemical technology can be applied to almost all chemical reactions, such as extraction and dispersion (such as ultrasonic extractor and disperser), synthesis and degradation, biodiesel production, microbial treatment, toxic organic pollutants and biological Degradation treatment, crushing and crushing of animal and plant cells (such as ultrasonic cell disrupter), aggregation and dispersion, etc. The energy density of the ultrasonic sound field is increased by trillions of times compared to the energy density at the collapse of the cavitation bubble, causing a huge concentration of energy. The sonochemistry and sonoluminescence caused by the extremely high temperature and pressure generated by the cavitation bubble , is the unique form of energy and material exchange in sonochemistry. Therefore, ultrasonic waves have a wide range of chemical reactions such as chemical extraction, organic synthesis, chemical reaction rate and yield, catalytic efficiency of the catalyst, ultrasonic anti-fouling and descaling (such as ultrasonic cleaning machine), biological cell pulverization, dispersion, and coagulation. The bigger the effect.

The main components of the sonochemical system function:

1. Ultrasonic vibration source (drive power supply): The 50-60Hz mains power is converted into high-power high-frequency (15kHz-100kHz) power supply to the transducer.

2. The transducer (transducer): converts high-frequency electrical energy into mechanical vibration energy.

3. Horn: Connects and secures the transducer and tool head, amplifies the amplitude of the transducer and transmits it to the tool head.

4. Tool head (introduction rod): The mechanical energy and pressure are transmitted to the work object and also have the function of amplitude amplification.

5. Connecting bolts: Connect the above components tightly.

main application

The earliest application of ultrasound in biochemistry should be to use ultrasound to break up the cell wall to release its contents. Subsequent studies have shown that low-intensity ultrasound can promote the biochemical reaction process, such as ultrasound irradiation of liquid nutrient base can increase the growth rate of algae cells, so that the amount of protein produced by these cells increased by 3 times.

The energy density of the ultrasonic sound field compared to the energy density at which the cavitation bubble collapses, the energy density is enlarged by trillions of times, causing a huge concentration of energy; the sonochemical phenomenon and sonoluminescence caused by extreme high temperature and high pressure generated by cavitation bubbles , is the unique form of energy and material exchange in sonochemistry. Therefore, ultrasonic chemical extraction, biodiesel production, organic synthesis, treatment of microorganisms, degradation of toxic organic pollutants, chemical reaction rate and yield, catalytic efficiency of the catalyst, biodegradation treatment, ultrasonic anti-fouling, biological cell grinding, dispersion And cohesion, harmonic chemical reaction has an increasing role.

Therefore, choosing a good ultrasonic chemical protection social security is very important.
