Ultrasonic dispersing processor is composed of ultrasonic vibration parts, special driving power and reaction kettle. Ultrasonic vibration components mainly include ultrasonic transducer, ultrasonic amplitude transformer, tool head (transmitter head), used to generate ultrasonic vibration, and the vibration energy into the liquid emission. A transducer converts incoming electrical energy into mechanical energy.
Its manifestation is the ultrasonic transducer in the longitudinal stretch back and forth motion, the amplitude is generally in a few microns. Such amplitude power density is not enough to be used directly. The amplitude transformer amplifies the amplitude according to the design requirements, isolates the reaction solution and the transducer, and also plays the role of fixing the whole ultrasonic vibration system. The tool head is connected with the amplitude transformer, which transmits ultrasonic energy vibration to the tool head, and then the ultrasonic energy is emitted into the chemical reaction liquid by the tool head.
Composition
1. Ultrasonic vibration source: convert 50-60hz mains electricity into high-power high-frequency power supply and provide it to the transducer.
2. Ultrasonic transducer: converts high frequency electrical energy into mechanical vibration energy.
3. Amplitude transformer: connect and fix the transducer with the tool head, and transmit the amplitude of the transducer to the tool head after amplification.
4. Tool head (lead-in rod) : transfer mechanical energy and pressure to the work object, and also have the function of amplitude amplification.
5. Connection bolts: tightly connect the above components.
Application
The application of ultrasonic disperser should be to smash cell walls with ultrasound to release their contents. Low-intensity ultrasound can facilitate biochemical reactions, such as irradiation of liquid nutrients with ultrasound can increase the growth rate of algae cells, thus increasing the amount of protein produced by these cells by three times.
Compared with the collapse of cavitation bubble, the energy density of ultrasonic sound field is increased by trillions of times, resulting in a huge concentration of energy. The acoustic chemistry phenomenon and photoluminescence caused by the extreme high temperature and pressure produced by cavitation bubbles are the special forms of energy and material exchange in acoustic chemistry. So, to the chemical extraction, ultrasonic biodiesel production, organic synthesis, governance, microorganism, degradation of toxic organic pollutants, chemical reaction rate and production rate, efficiency of catalyst, biodegradation treatment, ultrasonic antiscaling descaling, biological cell crushing, dispersion and condensation, and chemical reaction is more and more important role.
