Ultrasound Reactor for Paint Dispersion


Most engineers are familiar with ultrasonic energies being used for cleaning parts, welding plastics, or perhaps even for performing medical examinations. Produced by transducing piezoelectric-generated vibrations, ultrasonic energy applications include the production of emulsions and dispersions. Applied in the laboratory to make small quantities, use in paint systems has been investigated over the years. Scale-up efforts have proven to be very costly in capital investment and in power demands. Mechanical generation as compared to transduced electronic systems has changed all that, proving to be very efficient.

One of these methods provides a means for material to be in direct contact with high-energy cavatational forces. It does not involve high electrical energy or a complicated generating mechanism. This method provides a means for high-intensity processing of very large amounts of materials economically by a direct translation of kinetic energy produced in a pump into cavatational energy ultrasonically produced. Created in tandem along with high-pressure homogenization, this system provides complete and instantaneous emulsions and dispersions, perfect for those applications requiring high-intensity mixing.

Appropriate for both liquid-liquid applications and liquid-solid (emulsions), the material is pumped through a specially shaped orifice at high velocity of 300 feet per second or more, forming a flat stream. The jet of material then impinges on a knife-like blade, which creates waves or vortices of ultrasonic energy running perpendicular to the flow. The pressure drop created by the orifice and the ultrasonic cavatational forces combine to create a high-energy mixing effect. Pressures starting at 200 psi to as high as 5000 psi with flow rates up to 250 gal/min or greater are possible.

Sonochemical reactions

Three classes of sonochemical reactions exist: homogeneous sonochemistry of liquids, heterogeneous sonochemistry of liquid-liquid or solid–liquid systems, and, overlapping with the aforementioned, sonocatalysis (the catalysis or increasing the rate of a chemical reaction with ultrasound). Sonoluminescence is a consequence of the same cavitation phenomena that is responsible for homogeneous sonochemistry. The chemical enhancement of reactions by ultrasound has been explored and has beneficial applications in mixed phase synthesis, materials chemistry, and biomedical uses. Because cavitation can only occur in liquids, chemical reactions are not seen in the ultrasonic irradiation of solids or solid–gas systems.

For example, in chemical kinetics, it has been observed that ultrasound can greatly enhance chemical reactivity in a number of systems by as much as a million-fold;[16] effectively acting to activate heterogeneous catalysts. In addition, in reactions at liquid-solid interfaces, ultrasound breaks up the solid pieces and exposes active clean surfaces through microjet pitting from cavitation near the surfaces and from fragmentation of solids by cavitation collapse nearby. This gives the solid reactant a larger surface area of active surfaces for the reaction to proceed over, increasing the observed rate of reaction. 

While the application of ultrasound often generates mixtures of products, a paper published in 2007 in the journal Nature described the use of ultrasound to selectively affect a certain cyclobutane ring-opening reaction. Atul Kumar has reported multicomponent reaction Hantzsch ester synthesis in Aqueous Micelles using ultrasound.

Some water pollutants, especially chlorinated organic compounds, can be destroyed sonochemically.

Sonochemistry can be performed by using a bath (usually used for ultrasonic cleaning) or with a high power probe, called an ultrasonic horn, which funnels and couples a piezoelectric element's energy int
