Dust suppression for low-turbulence applications and fine particle control

The new developed DustBoss® DB-M (Fig.) is well suited to operating conditions involving very fine dust particles, including slag dust or fly ash. The unit generates an umbrella-shaped cloud of atomized droplets averaging 50‑200 µm in size, projecting the mist about 9 m under calm conditions. The powerful misting head is supplied standard with 9 atomizing nozzles and mounted on a 15-foot boom, but the design was engineered for its ability to be customized for specific dust types, particle behaviors or operating environments.

 

The new design features selectable flow settings and the company’s proprietary Variable Particle Sizing (VPS) Technology to improve capture efficiency. Nozzles can be added, removed or re-sized as the application dictates. Just 10 PSI of water pressure is required from the supply hose when using the integrated booster pump, giving the DB-M an output as high as 24 GPM at 200 PSI. An in-line 30 mesh filter stops any solids 600 µm and larger, and the manufacturer recommends that it be used at all times. If using potable water, nozzles can be inspected just once a year. Configured for US markets for 3-phase/480 volt/60 hertz power, the full current load is approximately 12 amps. It can be configured to match power supplies in virtually a region in the world. The recommended minimum generator set is 25 KW. The DB-M can also be supplied with an optional dosing pump for precise metering of odor control additives, surfactants to improve binding to dust particles, or tackifying agents to help seal ground-level dust and prevent it from becoming airborne.
