Sonic / Acoustic Cleaning Systems

.

(Eliminate Dust Build-Up Concerns)

Our Acoustic Cleaning Systems are designed to significantly improve the cleaning of Air Pollution Control Equipments, Material Handling & Storage Equipments, Heat Transfer Surfaces and areas of production where particulate buildup occurs.
These are air-operated devices that emit low frequency high energy sound waves. The sound waves are produced by compressed air rapidly entering the sound generator (driver), causing the diaphragm to flex. As the pressure is equalized, the diaphragm impacts the pedestal, generating a sound wave that is then amplified by the horn bell.

Proven Applications :

The sound waves generated by an Acoustic Horn create vibrations that break apart and dislodge material deposits from surfaces. The vibrations are powerful enough to break apart heavy concentrations of particulate, but gentle enough to not harm the surface. Once the material has been dislodged, gravity and/or gas flow remove it.

Acoustics On Spray Dryers

Spray drying is a common application for dry particulate collection in process related industries such as Food, Pharmaceutical, Ceramics and Chemicals. Spray drying consists of three basic steps:
1) Atomizing a liquid feed into a spray of fine droplets.
2) Mixing the spray with a heated gas stream (the liquid evaporates leaving dried solids).
3) Separating the particles from the gas stream (through a baghouse, cyclone or inside a chamber of the Spray Dryer).

One of the most common problems associated with Spray Dryers is the formation of wall deposits, caused by large droplets hitting and attaching to the chamber wall before they are dry. Excessive wall deposits and blockages can become problematic. Acoustic Cleaning Systems, when sized and placed correctly, can help to break up agglomerates on internal walls of Spray Dryers.
