Introduction of Ultrasonic Sonochemical Equipment
Introduction:
The severe bubble rupture during ultrasonic cavitation can cause extreme local temperatures, heating/cooling rates, and pressures, leading to many sonochemical processes, including ester exchange (used to produce biodiesel), pollutant degradation, sterilization and pasteurization, crude oil desulfurization, and more. Ultrasonic processors with high-frequency amplitude can perform sonochemical treatment of any scale.
Ultrasonic technology, as a physical means and tool, can generate a series of nearly extreme conditions in the medium of chemical reactions. Energy can not only excite or promote many chemical reactions, accelerate the speed of chemical reactions, but also change the direction of many chemical reactions to produce unexpected effects and effects. The sonochemical phenomenon caused by high temperature and high pressure generated by ultrasonic cavitation reaction is a unique form of energy and substance exchange in sonochemistry. So ultrasonic equipment is increasingly widely used in various chemical and biological industries, such as extraction, crushing and mixing, emulsification, dispersion and stirring, defoaming and degassing, and accelerating reactions.
The high amplitude ultrasound processor we provide is suitable for various sonochemical applications. It can maintain extremely high ultrasonic amplitude at any operational scale, thus greatly enhancing sonochemical processes, and can directly implement laboratory results in production environments.
Principle:
In chemistry, cavitation refers to the formation, growth, and implosion of tiny bubbles. Cavitation bubbles are composed of compression and expansion cycles. The compression cycle causes positive pressure in the liquid to push molecules together. On the contrary, the expansion cycle causes negative pressure to pull molecules apart from each other. Once the bubble grows very rapidly until it cannot absorb the energy in the sound wave. In this case, the liquid will pour in and the bubbles will burst. The entire process disrupted the attraction of molecules in the liquid phase. The explosion of cavitation bubbles is very fast, and these tiny bubbles formed during ultrasonic treatment will raise the temperature of the liquid around the cavity and generate local hotspots. However, the area is so small that the heat dissipates quickly. On the other hand, a very high pressure is generated during bubble rupture, approximately 1000 atmospheres. Although extreme conditions are very limited, ultrasonic treatment can create extreme physical and chemical conditions in liquids. This allows ultrasound to be applied in extraction, crushing and mixing, emulsification, dispersion and stirring, defoaming and degassing, accelerating reactions, etc
