Dust Control Ultrasonic Air Atomizing Nozzle
The mechanical ultrasonic nozzle has a carefully designed resonator to produce high frequency wave. Compressed air passes through the nozzle’s inner bore through a convergent/divergent section at high velocities and expands into a resonator cavity where it is reflected back to complement and amplify the primary shock wave.The result is an intensified field of sonic energy focused between the nozzle body and the resonator cap. Any liquid capable of being pumped into the shock wave is vigorously sheared into fine droplets by the acoustic field. Air bypassing the resonator carries the atomized droplets downstream in a soft plume shaped spray.
The ultrasonic atomizing nozzle is mainly atomized based on the following 2 steps:
The average size for the atomized droplets are very fine and uniformly, which means the sizes for the largest droplets are almost the same with the smallest one. This point is very important for dust suppression industry.
The shaking that caused by collision between the shaking tip and high speed air flow can prevents the dust and other particles from adhering to the orifice, thus such nozzles would working properly and do not need maintenance frequently
Dry fog nozzle have proven to significantly reduce fugitive dust from a variety of material handling points, including conveyor transfer points, trippers, reclaimers, crushers, screens, truck dumps, railcar loading/unloading, ship loaders-unloaders, and ash silo discharge chutes.
