What is ultrasonic sonochemistry? As a physical tool and tool, ultrasonic technology can produce a series of near-extreme conditions in various media of chemical reaction. This energy can not only stimulate or promote various chemical reactions, but also accelerate chemical reactions. Speed, and even the direction of certain chemical reactions, produces 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 organisms. Degradation treatment, pulverization and fragmentation of animal and plant cells (such as ultrasonic cell disruption), aggregation and dispersion. The energy density of the ultrasonic sound field is expanded by tens of billions of times compared with the energy density of the cavitation bubble collapse, causing a huge concentration of energy, sonochemical phenomena and sonoluminescence caused by extreme high temperature and high pressure generated by cavitation bubbles. Is a unique form of energy and material exchange in sonochemistry. Therefore, ultrasonic has a variety of chemical reactions such as chemical extraction, organic synthesis, chemical reaction rate and yield, catalytic efficiency of the catalyst, ultrasonic anti-scaling and descaling (such as ultrasonic cleaning machine), biological cell pulverization, dispersion and aggregation. The bigger the role.
Main components of ultrasonic sonochemical system:
1. Ultrasonic vibration source (drive power supply): converts 50-60 Hz mains into a high-power high-frequency (15 kHz-100 kHz) power supply, which is supplied to the transducer.
2. Transducer (transducer): converts high frequency electrical energy into mechanical vibrational energy.
3. A horn: The transducer and the tool head are coupled and fixed, and the amplitude of the transducer is amplified and transmitted to the tool head.
4. Tool head (introduction rod): It transfers mechanical energy and pressure to the work, and also has the function of amplitude amplification.
5. Connecting bolts: Connect the above components tightly.
