The use of ultrasonic cavitation Value

Crystallization, precipitation and spray crystallization, precipitation and spray commonality of these three processes is that they are the power of ultrasound in a liquid medium to produce a special form material. Ultrasonic cavitation ultrasonic crystallization and precipitation can promote crystallization, in certain cases, can be expressed as a simple aggregation, that is precipitated. QIU Tai, etc. The effect of ultrasound on sucrose crystal nucleation process.

Ultrasonic Enhancement separation trends further strengthen ultrasound study of the separation process, seek effective and feasible approach is to strengthen the process leading subject of theoretical significance and application value.

Work in this area include:

Continue to strengthen the ultrasound field experimental study of the separation process, to seek ways to enhance the use of efficient solid-liquid immersion ultrasound married liquid-liquid extraction and filtration separation process;

Analysis of the acoustic interaction in the form of energy and matter, combined with the separation process with its own characteristics, to explore the mechanism of ultrasound on the separation process; try to strengthen the new separation technology of ultrasound.

The results showed that the sound field, the crystal nucleation process can be realized at low saturation, the resulting homogeneous nucleation than other methods, complete, smooth, grain size distribution range is narrow,

It found that the nucleation rate can be accelerated to shorten the induction period, significantly increase the crystallization yield, the higher the frequency, the shorter the crystallization time, simple equipment, investment relatively Province. In this study, based on the ultrasonic wave from the crystallizer has begun to be industrially.

Molten metal during the curing sonicated grains become fine can modify their physical characteristics and mechanical strength elongation. Insulated steel ladders sonication showed that it can make the grain size is reduced from 200m to 2530m, ductility increased by 30% to 40%, the mechanical strength increased by 20% to 30% in the pharmaceutical industry in order to obtain fine and uniform particles, ultrasound has been used for the production of crystalline oral pharmaceutical or subcutaneous injection suspensions. Industrial production is concerned, an important benefit of ultrasound-assisted crystallization or precipitation of the precipitate is not fixed in a condenser to cool the deposition, thus guaranteeing a cooling rate of the system to obtain a homogeneous distribution. Ultrasonic atomization ultrasonic atomizing liquid, can be uniform and can control the size of droplets. When the breast of liquid oxygen when the ultrasonic atomization, the droplet size depends on the frequency, the operating frequency is increased, the droplet becomes small.
