What Makes Ultrasonic Nozzles Unique?

Unlike two-fluid nozzles, ultrasonic nozzles do not require a small aperture to achieve atomization. Instead, the liquid passes through a larger aperture without pressure and uses ultrasonic vibration to atomize the liquid, which not only avoids the risk of nozzle clogging, but also The resulting low-flow spray is easier to control and causes little splashing. Each ultrasonic nozzle works at a specific resonant frequency, and the frequency determines the size of the atomized particles. We can achieve spraying applications with different needs by selecting ultrasonic nozzles with different frequencies. For example, when testing with water, the average spray particle size produced by a 120KHz ultrasonic nozzle is 15um, and the particle size decreases as the frequency increases. In addition, according to the size of the spraying range, ultrasonic nozzles are generally classified into: wide spray ultrasonic nozzles, gathering ultrasonic nozzles, fine ultrasonic nozzles and linear ultrasonic nozzles. For some special applications, they are also divided into scattering ultrasonic nozzles, penetration ultrasonic nozzles, high temperature pyrolysis ultrasonic nozzles, and spray drying ultrasonic nozzles. Among them, high-temperature pyrolysis ultrasonic nozzles and spray drying ultrasonic nozzles are special ultrasonic nozzles used for ultrasonic spray pyrolysis and drying of ultrafine powder preparation.

For wide-spray ultrasonic nozzles, the spray is entrained by the controlled carrier gas passing through the flat carrier gas guide plate, forming a fan-shaped spray that falls on the substrate in an elliptical shape. By adjusting the spray height, the width of the spray onto the substrate can be adjusted. By using multiple nozzles in parallel, unlimited width can be applied to larger areas for spraying applications.

The converging ultrasonic nozzle uses a special shrinking flow channel design to evenly gather and distribute the carrier gas. The spray is sprayed out in a focused form by the carrier gas diversion, which effectively reduces the spraying area and is suitable for spraying needs of smaller areas.

Scattering ultrasonic nozzles, also known as swirling ultrasonic nozzles, use a special vortex flow channel design to convert the carrier gas into a uniform rotating airflow, causing the spray to scatter and eject in the form of a cyclone. For vertical or curved surfaces with angles, etc. The base material has better spraying effect.

The penetrating ultrasonic nozzle, as the name implies, can penetrate into the substrate for spraying. This ultrasonic nozzle is an elongated ultrasonic nozzle. Through the lengthened design of the front end of the nozzle, it can be penetrated into a narrow space for spraying. It is mainly used for spraying applications on the inner wall of pipelines such as vacuum blood collection tube spraying and silicone oil spraying in syringes.
