Ultrasonic degassing is an efficient method of removing dissolved gasses and/or entrained gas bubbles from a variety of liquids. Unlike vacuum degassing, which is a batch approach, ultrasonic degassing can be done in a continuous-flow mode.
Ultrasonic degassing (deaeration, in the case of air) is an efficient method of removing dissolved gasses and/or entrained gas bubbles from a variety of liquids, including water, candle waxes, aluminum alloy melts, epoxies, silicone oils, adhesives, coating solutions, beverages, polymers, inks, paints, transformer oils, emulsion and suspension products, motor oils and many more. Unlike vacuum degassing, which is a batch approach, ultrasonic degassing can be done in a continuous-flow mode.
Liquids containing dissolved gases can reduce the effectiveness of the ultrasonic pressure wave propagation. When subjecting liquids with dissolved gases to ultrasonic energy, the dissolved gases may come out of solution and form bubbles that dampen the effectiveness of the ultrasonic power. Thus degassing is a necessary procedure prior to starting any ultrasonic process.
Ultrasonic energy can be used to aid in degassing the liquid as follows: when subjecting liquids to ultrasonic power, the sound waves that propagate from the ultrasonic radiating surface into the liquid produce an alternating high-pressure and low-pressure cycles. During the low-pressure cycle, the ultrasonic waves can create small vacuum bubbles or voids in the liquid. The large number of small bubbles generates a high total bubble surface area. The bubbles are also well distributed in the liquid. Dissolved gas migrates into these vacuum (low pressure) bubbles via the large surface area and increases the size of the bubbles. The ultrasonic waves assist in the touching and coalescence of adjacent bubbles leading to an accelerated growth and rise of the bubbles, thereby effectively degassing the liquid. The ultrasonic waves will also help to shake bubbles off vessel surfaces and will force smaller bubbles resting below the liquid surface to rise through and release the entrapped gas to the environment.
How does degas mode work? Essentially, it is a pulse mode of ultrasonic cleaning. High intensity ultrasonic pulses are produced. In between pulses, the gases have time to coalesce into bubbles and float to the top of the tank, where the bubbles pop and the gases are released into the air.
