Atomized Mist Cannon Manages Dust in Unfavorable Weather Conditions
Published: 27/6, 2022
BossTek has introduced the next advancement in industrial dust suppression— the DustBoss® DB-60 Surge®, a powerful cannon designed to fight dust with maximum efficiency.
Developed in response to the needs of customers in areas with variable winds, the DB-60 Surge features water propelled at high velocity from a center nozzle, combined with the industry-proven fan and misting ring system. With three remote-controlled stages and precision oscillation for optimum command over water volume and coverage area, the cannon uses high-powered jets that surge through the wind for over 250 ft (76.2m) to suppress both surface and airborne dust. The result is effective and versatile dust mitigation in challenging weather for outdoor operations ranging from demolition to bulk material processing and storage.
The DB-60 Surge combines the power of an industrial fan, misting ring and heavy-duty barrel with the reach and force of a central high-pressure spray nozzle. The pressurized spray resists wind shear and even uses the force of the wind to further fragment and carry the droplets, enhancing its dust suppression capabilities. This is achieved without the need for the high water output associated with a hydrant-dependent hose or industrial sprinkler system.
In high-wind situations, dust is lifted into the atmosphere and carried beyond the site line over long distances, which can lead to permit violations. Operators of bulk storage mounds, demolition sites, ports, recycling material piles, etc. often mitigate particulate emissions using a sprinkler or hose to saturate a material’s surface. The higher the wind, the more water pressure is required to break through the shear, resulting in greater amounts of water filling the surrounding work area—often 300 lpm (1,135 lpm) or more.
There are several issues associated with the use of hoses and industrial sprinklers. Hoses typically require manual labor, removing workers from other critical tasks. Moreover, both sprinklers and hand-held hoses contribute to high water bills. Taking compliance and expenses into consideration, the long-term cost of operation for sprinklers and hoses is higher than it might appear.
The DB-60 Surge addresses wind, labor and water usage issues. While striving to stay compliant with dust regulations, operators can now better match the water requirements to the specific application. Fed by a standard 1.5-in (38mm) hose with a cam-and-groove quick disconnect coupling, the powerful booster pump delivers as much as 500 psi (27.5 bar) of water pressure to the center nozzle, with an output of 37-100 gpm (140-378 lpm).
Controlled by a three-stage system adjusted by a hand-held remote, the first stage is highly effective on moderate days for airborne and surface coverage. It uses the powerful 30,000-ft3/min (849.5-m3/min) fan and misting ring to deliver millions of fine atomized mist droplets over a wide area, which collide with tiny dust particles and drag them to the ground. For windy days, stage two features a pressurized stream delivered by the central nozzle. And on the most blustery days, operators can utilize the fan, misting ring, and center nozzle for maximum coverage.
Versatility and coverage area are extended with the customizable 359º horizontal oscillation range and 0º-50º vertical throw angle. Using the hand-held remote, the operator can raise the spray angle to reach extended heights, directing the 250-ft (76m) spray to areas such as high-reach demolition or across the beam of large bulk cargo ships. The oscillation range is easily controlled with the left and right trigger of the remote control to customize the precise desired horizontal range.
Mounted on a heavy-duty roadworthy trailer for towing at highway speeds with a standard ball hitch, it can be placed by a pickup truck, skid steer or lift truck wherever dust suppression is needed. As supplied, the DB-60 Surge can run potable or non-potable water, as it is equipped with two in-line 30 mesh, 595-micron filters to avoid clogging. One filter is located at the water entry point to the booster pump, another prior to the pipe feeding the central nozzle.
After the initial setup, the DB-60 Surge requires no labor to operate. The remote control has a 1,000-ft (305m) range, so operators using heavy machinery from high-reach excavators to front loaders can command the machine without leaving the cab. Other options are available, including tower mounting and a version of BossTek’s popular Fusion lineup, which pairs the Surge with a generator to alleviate the need for a nearby power source.
