Ultrasonic degassing is the process of removing dissolved gas and/or trapped small air bubbles from a liquid. Gases removed from various liquids including water, candle wax, polymers, epoxies, silicone oils, adhesives, paints, beverages, inks, coatings, transformer oils, emulsion and suspension products, motor oils, etc. wait. Degassing can significantly improve the quality of the final product (reduced defects, improved aesthetics, etc.), and unlike vacuum degassing with batch methods, ultrasonic degassing can be performed in continuous flow mode.
Working principle
Ultrasonic waves propagate from the acoustic emitter into the liquid medium, generating alternating positive and negative pressure phases. In the negative pressure (thinning) stage, sufficiently high-intensity ultrasonic waves can overcome the intermolecular adhesion and generate a large number of near-vacuum microbubbles in the liquid. Bubbles take in more gas as they expand and release it as they contract, so their volume increases rapidly. This process is called "directed" or "rectified" diffusion. Due to the homogeneous distribution of gas bubbles in the liquid and the large total surface area during gas phase acoustic cavitation, the migration of dissolved gas is fast and uniform throughout the affected liquid volume. The result is the formation of large numbers of oscillating bubbles containing gas previously dissolved in the liquid medium. As the bubbles dance in the ultrasonic field, they accelerate each other and merge to form larger bubbles. This process proceeds rapidly until the bubble achieves sufficient buoyancy to float on top of the liquid and release the previously trapped gas into the environment.
Cavitation
Ultrasonic degassing is caused by the phenomenon of cavitation. Ultrasonic waves passing through the liquid cause it to compress and expand continuously. High-intensity ultrasound provides the energy needed to disperse the liquid phase. When the maximum pressure is reached, at the point where the cohesion is weaker, a liquid rupture occurs. After this rupture, an overpressure was developed at the point where the rupture occurred and some cavities were found to exist. In these cavities, the gas dissolved in the liquid explodes after a short time in the form of bubbles.
Advantage
1. Compared with other processes, ultrasonic degassing does not require high temperature, high pressure, good safety, simple operation and convenient maintenance.
2. Compared with the conventional method, the ultrasonic equipment is simple, the production cost is low, and the comprehensive economic benefit is remarkable.
3. With broad spectrum and wide applicability, most liquids can be degassed by ultrasonic waves.
4. Make your liquid material effect consistent;
5. Elimination of dissolved gases and/or entrained air bubbles that interfere with the intended use of the liquid;
6. Improve the appearance, while degassing, homogenizing and extending the shelf life of the liquid;
