System Design

The Design of the

system is based on a very unique device which can produce a very dense fog of 1 - 10 micron size water droplets which literally blanket the dust source and keep the dust particles from becoming airborne. It does this at low cost, both from a capital and a maintenance standpoint, while achieving all of the goals stated above for an ideal dust suppression system.

The

fogger is an air driven acoustic oscillator for fogging liquids by passing them through a field of high frequency sound waves. This is accomplished by compressing air upstream of a specially designed converge section of the fogger. To further enhance the fogging capabilities, a resonating chamber in the path of the air stream reflects the air stream back at itself to amplify and complement the primary shock wave.
Once this standing shock wave is generated, water is delivered through annular orifices where it is first sheared into relatively small droplets. These small droplets are then carried by the primary air stream into the intense shock wave where the sound energy is converted into work by exploding the droplets into thousands of micron size droplets . After having done its work, the air then escapes around the resonating chamber and carries the droplets downstream in a soft, low velocity fog.

The design of this fogger has obvious benefits regarding the control of respirable dust. However, its inherent design features also make it extremely reliable from a maintenance standpoint. Since the

fogger does not rely on high pressure on the water side to achieve maximm atomization, wear problems are virtually eliminated as is the need for high pressure water pumps.

The

fogger cleans itself while operating with high frequency sound waves much the same way that a sonic laboratory cleaner works. The nozzle has no moving parts and is constructed of 100% stainless steel as compared to some competitors who use brass parts. This eliminates wear and corrosion and insures years of maintenance free service even with poor water quality as many material handling plants have. Undissolved sediment in the water that is larger than the liquid orifices is easily filtered out by our system.
