Ultrasonic Scaling Prevention Device 20khz For Boilers Pipelines Heat Exchangers Filters

The ultrasonic descaling equipment mainly consists of an ultrasonic generator, an ultrasonic vibration disc, a cleaning tank, etc. Ultrasonic descaling mainly utilizes an ultrasonic power source to generate ultrasonic energy on the corresponding ultrasonic oscillator, continuously passing through the cavitation effect in the liquid, causing the dirt to be dispersed, loose, broken, damaged, and detached under the action of ultrasound, making it difficult to adhere to the pipe wall. Thus achieving the effect of ultrasonic descaling. The principle of ultrasonic descaling is mainly reflected in the following aspects:

1. Cavitation: The energy of ultrasound directly generates a large number of voids and bubbles in the processed fluid medium. When the sound pressure or intensity reaches a certain level, bubbles will rapidly expand and then suddenly close. Generate strong pressure peaks within a certain range, with local pressure peaks reaching thousands of atmospheres. Under the action of peak pressure, the substances forming scale are broken and suspended in water, causing the natural scale layer to be destroyed and easily detached. The purpose of ultrasonic descaling.
2. Shear effect: Ultrasonic radiation acts on the scale layer, pipe wall, and water body. Due to different responses to ultrasonic frequencies, the three generate asynchronous vibration and high-speed relative motion. Due to the speed difference, relative shear forces are generated at the interface between the oxide layer and the heat exchanger tube wall, causing fatigue and loosening of the oxide layer, thereby achieving the goal of ultrasonic descaling.
3. Inhibition effect: Changes the physical and chemical properties of the fluid through the action of ultrasound, inhibiting the nucleation and growth of ions in water on the pipe wall. Therefore, the number of dirt ions attached to the surface of the heat exchanger has decreased. Practical research has confirmed that the longer the ultrasonic action time, the better the effect of preventing scaling substances from scaling.
In addition, the vibration of gas bubbles scrubs the solid surface. Once there are drillable cracks in the dirt layer, bubbles immediately "drill" into the vibration, causing the dirt layer to fall off. Emulsification and solid particles self detach. When ultrasonic waves propagate in the cleaning solution, positive and negative sound pressure is generated, forming a jet that impacts the cleaning part. The interface will generate high-speed micro jets, which can destroy dirt and remove or weaken boundary dirt.

Ultrasonic descaling technology has been widely used in various industrial cleaning processes, such as cleaning heat exchangers, membrane separation equipment, industrial pipelines, and surface cleaning of overall devices. It can effectively remove various types of scale and blockage, including sedimentation, rust, sediment, etc.
