    Protecting a Stockpile

For low level hazardous materials we see some facilities binding the waste with other materials for landfill by use of a mixing pit. Discharging the material to a pit and mixing operations can benefit by the use of Dry Fog. Fog controls can be tied to discharge start signals. Equipment operators mixing the material can use a radio remote control to activate and deactivate the fogging manifolds as needed.

Preventing dust generation at Storage Piles is becoming an important issue. DustTAMER Wind Fence Systems can reduce the the amount of dust generated by stacking and working a storage pile.

DustTAMER is a much less expensive alternative to Domes and Buildings. Our fabric is designed to withstand winds in excess of 100 MPH and is resistant to the effects of UV Rays. Some installations are approaching 20 Years of service with no significant fabric deterioration.  DSI can help with the fence layout and supply the fabric and attachment hardware.

Dry Fog™ can effectively suppress the dust at conveyor transfer points, without wetting the material.  Unlike dust collection systems, there is no secondary waste stream as we do not collect the dust, but simply "knock down" the airborne dust at the point of creation. Collectors typically deposit concentrated amounts of collected dust back onto the conveyor belt only to create more issues downstream.

DSI has worked on projects that range from low hazard level liquid waste being mixed with dry stabilizers for landfill to nuclear waste remediation projects. These nuclear waste projects include materials being excavated in contained areas to waste volume reduction facilities where contaminated waste is ground up and transferred to long term storage containers.

Dry Fog works by injecting sub-micron water droplets into the air at the point of dust creation. The fog droplets attach to like size airborne dust particles. The slightly wetted particles agglomerate to other particles, adding sufficient mass to settle the dust back into the conveyed product within the covered transfer point.

Truck Tippers are commonly used at Pulp and Paper facilities for wood chips, sawdust and hog fuel. DSI has many years of experience in dealing with these difficult dust sources.

At the truck tipper, our system is designed to suppress dust using two stages of attack. First by filling the dump pocket with fog prior to the actual dump from the truck. This "pre-fog" will supply a reservoir of fog-charged air that, when displaced by the falling material will attach to the airborne dust particles and settle them out in the hopper due to their increased mass. To do this, the fog manifolds at the dump hopper activate as soon as the tipper platform starts to rise.

Stage two is the same foggers operating during the complete dump cycle until the platform rests back on the ground. This stage will attack the creation of additional dust at the dump as the truck continues to dump.

Dry Fog is also used at the hopper discharge to the take-away conveyor and transfer points down-stream.

Conveyor Transfer Points can easliy generate concentrations of dust that exceed safe limits for both respirable and explosive dust. At Fuel Handling Systems, the risk of fires, explosions increase significantly with fuel sources like PRB Coal. Meeting Fire and Safety Regulations can be a challenge. However, there is a Dry Fog Solution.

Dry Fog works by injecting sub-micron water droplets into the air at the point of dust creation. The fog droplets attach to like size airborne dust particles. The slightly wetted particles agglomerate to other particles, adding sufficient mass to settle the dust back into the conveyed product within the covered transfer point. Used at truck tippers, screens, yard & plant conveyors, including reclaim, gallery, tripper conveyors and silos.
