New system is designed to extend reach and improve aim of dust suppression equipment.
The equipment manufacturer Dust Control Technology (DCT), based in Peoria, Ill., has designed a new system that addresses operations that generate dust in fixed locations. The system is suited for slag handling, aggregate processing, recycling operations and coal handling.
The company says that the new design completes a range of systems that deliver millions of 50-200 micron droplets per minute from above dust-generating activities.
“The tower mounts can deliver a focused mist to the areas where dust is created,” says Laura Stiverson, DCT general manager. “This allows the DustBoss units to concentrate virtually their entire output directly to the source of the problem.” The company says the new tower systems are designed to withstand wind loads of at least 100 miles per hour, and are constructed of carbon steel pipe, hot dip galvanized to resist corrosion.
Additionally, the tower units can be modified to address specific particle sizes or service environments. “In some applications such as slag handling, the dust particles can be so small that they are more effectively managed with smaller droplets,” Stiverson says. “In other situations, reduced flow may be preferred to protect moisture-sensitive materials. The most effective suppression takes place when the dust particles and droplets are roughly the same size.”
Three tower sizes are currently available. The 6-inch base tube is generally employed on tower heights less than 15 feet and is compatible with the company’s standard oscillation package. For greater elevation, an 8-inch diameter tower is recommended.
The heavy-duty design is the 10-inch diameter flange-mounted towers, which are secured directly into concrete. Available in heights up to 20 feet, the large diameter allows hoses and power cords to be routed inside the tower for protection and what the company describes as a “cleaner” appearance. The flange-mounted units feature programmable oscillation, with a customer-settable range from 0-359 degrees. Climbing rungs, work platforms, booster pumps and additive metering systems are all available as options.
Once installed, users have two options for raising and lowering the tower. The manual jack has a long handle attached, allowing operators to rotate the handle to change the height from the ground. When fitted with the optional electric jack, changes can be made via the control panel or remote control unit. With motion limits set by the program, the operator simply activates the jack until it reaches the desired position, allowing quick and easy adjustments to accommodate weather changes or specific work activities.
DCT says that the ability to network multiple machines and/or automate the on-off cycles can be a big advantage to large operations. “Automated units can be operated from a single radio-controlled, hand-held remote to conserve resources and avoid over-saturation, with the units running only during dust-generating activity,” Stiverson notes. The radio-powered remote control allows rapid start-up or adjustment of the machines by a single operator, without any manual contact.
In fully-automated systems, the network can be equipped with sensors that track wind and weather details, with customized software and programmable logic control via computer. The systems can be programmed to manage start/stop cycles based on dust monitor readings, motion sensors or weather input. The technology allows users of DustBoss equipment to automatically adjust elevation, oscillation range and other features on any number of machines to improve suppression efficiency and free up manpower for other tasks.
