Introduction to ultrasonic sonochemical processor:
1. Acoustic chemistry is an emerging interdisciplinary subject that uses ultrasound to accelerate chemical reactions or trigger new reaction pathways to increase the yield of chemical reactions or to acquire new chemical reaction products.
The main driving force of sonochemical reaction comes from acoustic cavitation, from the extreme physical conditions such as high temperature (greater than 5 000K), high pressure (greater than 2.03×108Pa), shock wave or microjet accompanying cavitation bubble implosion.
2. Applications of Ultrasonic Chemistry Sonochemistry has a wide range of applications and can be broadly classified into nine categories: biochemistry, analytical chemistry, catalytic chemistry, electrochemistry, photochemistry, environmental chemistry, mineral chemical treatment, extraction and separation, Synthesis and degradation.
product manual:
When ultrasonic waves propagate through a liquid medium, they produce mechanical, thermal, optical, electrical, and chemical effects through mechanical action, cavitation, and heat. In particular, high-powered ultrasonic waves produce intense cavitation, which locally forms transient high temperatures, high pressures, vacuum and microjets.
As a physical means and tool, ultrasonic technology can produce a series of near-extreme conditions in a medium commonly used in chemical reactions. This energy can not only stimulate or promote many chemical reactions, accelerate the speed of chemical reactions, and even change certain The direction of the chemical reaction produces some unexpected effects and miracles. It is generally believed that the above phenomena occur mainly due to the mechanical action and cavitation of the ultrasound, which are the result of changing the conditions and environment of the reaction.
Mechanical action - Ultrasonic waves are introduced into the chemical reaction system. Ultrasonic waves can force the material to move vigorously. The one-way force accelerates the transfer and diffusion of the material. Instead of mechanical agitation, the material can be peeled off from the surface, thus renewing the interface.
Cavitation - In some cases, the generation of ultrasonic effects is related to the cavitation mechanism, which refers to the series of dynamics of tiny bubbles (holes) present in the liquid under the action of sound waves. Learning process: oscillation, expansion, contraction and even collapse. In the event of cavitation, the local state of the liquid changes greatly, resulting in extreme high temperatures and high pressures. Provides a new and very special physical and chemical environment for chemical reactions that are difficult or impossible to achieve under normal conditions.
Catalytic chemical reaction -
1 high temperature and high pressure conditions facilitate the decomposition of reactants into free radicals and divalent carbon, forming a more active reaction species;
2 shock wave and micro jet have desorption and cleaning effect on solid surface (such as catalyst), which can remove surface reaction products or intermediates and catalyst surface passivation layer;
3 shock waves may damage the structure of the reactants;
4 dispersed reactant system;
5 ultrasonic cavitation metal surface, shock wave causes deformation of metal lattice and formation of internal strain zone, and enhances chemical reactivity of metal;
6 causes the solvent to penetrate deep into the solid, resulting in a so-called inclusion reaction;
7 Improve catalyst dispersion.

The focused probe high power ultrasonic sonochemical processing system can be operated in two ways.
One way is that the liquid to be treated is circulated and reacted in a normal container, and an ultrasonic emitting head is inserted into the liquid to emit ultrasonic waves. The treated liquid flows through the container while being subjected to intense ultrasonic waves. The size or temperature of the reaction vessel can be high or low. In general, for containers of the same size, the smaller the flow rate of the liquid, or the longer the residence time in the container, the stronger the intensity of the ultrasonic action, and of course the less the yield. On the contrary, the shorter the control ultrasonic action time is, the lower the ultrasonic action intensity is, and the higher the flow rate (ie, the yield). This method is also suitable for anti-scaling and descaling applications.
Another treatment method is to use a special ultrasonic reactor for our company to form a complete sonochemical reactor. The liquid to be treated flows from one end of the reaction vessel, passes through the action of the ultrasonic waves, and then flows out from the other end. This way the changes to the original chemical system are minimal and the effect is immediate.
