Targeted dust control for low-turbulence applications

Dust Control Technology has engineered a smaller version of its low-turbulence atomised mist unit for applications that require precision particle control without the disturbance of a fan-driven design.

Developed for applications such as conveyor unloading points and other limited-space dust-producing areas, the DustBoss DB-M Mini is built to provide effective suppression without material disruption or saturation.  Generating a cascading mist of atomised droplets averaging 50-200 microns in size, the unit has a throw of about 10 feet (3.04 metres) under calm conditions. The result is effective fugitive particle management at the source of the problem, with little pooling or runoff

“We’ve found suppression is best achieved by controlling dust at the source whenever possible,” said Dust Control Specialist, Carl Harr, from Dust Control Technology (DCT). “We designed this compact version of the DB-M to fit into smaller spaces to directly address those specific problem areas.  It’s well suited to applications involving very fine dust particles, such as slag dust or fly ash,” he added.

The standard boom length is 2 feet, but can be specified anywhere from 1 to15 feet (.3 to 4.57m).  It is fitted at the end with a misting head featuring nine atomising nozzles.  With a minimum required pressure of just 10psi (.69bar) and a maximum of 100 psi (6.89 bar), water is fed through a standard 3/4" swivel hose coupling or an optional 1-1/2-in NPT connection.  The water travels through an in-line 75 mesh (200 micron) filter, up the boom and to the head, where the atomising nozzles fracture the flow into millions of droplets, which are distributed evenly across the target area.

Along with the customisable boom length, proprietary Variable Particle Sizing (VPS) Technology allows specialised nozzles to be added, removed or replaced on the head in order to customise droplet sizes for optimum suppression. If using potable water, nozzles need only be inspected once per year.

An optional dosing pump can be attached for accurate metering of odour control additives, surfactants to improve binding to particles, or tackifying agents to help seal ground-level dust and prevent it from becoming airborne.  The unit runs an water pressure alone, requiring no electrical hookup.

“This is an important addition to our product line, because operators now have a compact point-of-emission solution,” Harr concluded.  “Along with less fugitive dust, when added to a workplace air quality control plan, operators may find a lower burden is placed upon their other dust suppression methods and air filtration systems."
