In order for the sound source is required and also mechanical vibration in an elastic medium (solid, liquid or gas) through which the sound wave propagates.

The Acoustic Units are designed scientifically sound generators, within a controlled low-frequency band, produce high levels of energy and pressure. The sound energy carrying waves generated overcomes the forces of particle-particle and particle - surface deposits accumulated materials cohesion.

For the generation of these waves is necessary compressed air you get from the ground to the required pressure, passes the Air Preparation Unit that regulates it, filter and lubricating. A solenoid valve located at the outlet of Air Preparation Unit is powered by the Power Control Unit to be activated according to an established program operation and allow the entry of air, and conditioned on the acoustic unit.

This compressed air to enter the Acoustical Unit at levels preset pressure, the diaphragm flexes or housed inside membrane allowing the passage of air to a secondary chamber pressures to equilibrate the membrane returns to its original position. Repeat this process multiple times a vibration that it passes through the particular geometry of the bell, to produce the desired level of specific frequency sound is generated.

The key features that determine if an acoustic cleaning system is effective at a particular problem is the particle size, moisture content and density of the particles. But it must always be cautious because the particles change with temperature characteristics and time. Particles with lower moisture content to 9% and size between 20 microns and 5 mm are ideal for a successful cleaning. The upper temperature limits for the use of acoustic cleaners cleaning applications Boilers dependent melting point of the ash. With refractory alloy steel cleaners have been used at temperatures above 1000 ° C.
