What Dust Control Solutions Can Be Used For Winter Conditions?

INTRODUCTION

WINTER! A word that is often welcomed and even celebrated if that means staying at home and sip hot coffee by a fire. For many companies, winter conditions and heavy snow create headaches and can cause costly delays or downtime. Demolition and construction companies working to meet project deadlines rely on the ability to work through any weather condition (favorable or unfavorable) thrown at them by mother nature. So, when the weather outside is cold and freezing, you can rely on EnviroHandling.

During Winter, water-based suppression equipment like water mist cannons and water sprayers are not effective in controlling dust because the solutions freeze and destabilize. Using water-based dust suppression systems during winter can create slick conditions that are hazardous for workers to walk and work on. That doesn’t mean water has to be taken out of the equation, though. It needs a modifying on the molecular level.

DUST CONTROL SOLUTIONS/TECHNIQUES FOR WINTER CONDITIONS

Below are the techniques you used to reduce/suppress dust:

1. Slow the Wind:  

Involves the use of either Weathersolve’s windbreakers or wind fence.

Windbreakers

These are barriers designed by WEATHERSOLVE to slow the speed and redirect the flow of wind. These are widely used in countries like Alaska with freezing conditions. Effective windbreaks do not stop the wind but rather it breaks its accelerative movement, to slow it down. Effective windbreaks will not create excessive commotion or wind swirls. Windbreak materials include picket and board fences (with gaps between pickets), snow fences, nets, steel, beams, and rows or hedges of plants. Windbreaks are most useful when designed for snow or winter conditions.

Wind Fence

Provides unique advantages for industrial dust control solutions. Wind fences are ideal for dust control over freezing conditions with the most common designs being 100ft (30 meters) or higher. Wind fences can reduce wind speeds by over 50% of the incoming wind speed over large areas, and over 80% over localized areas. A wind fence tends to reduce the wind on the site which in a way reduces the dust emitted from building/demolishing a project. Most companies use wind fences during winter to reduce dust.

2. Rotary Process Valves:

The prime function of a rotary airlock is to regulate the flow from one chamber to another while maintaining a good airlock condition. This product is one of the reliable products from ROTOLOCK—a company we represent. The product is mainly in dry powder or granular form. In the dust filtration field, a good airlock is essential on cyclone and bag filter applications so that the manufacturers quoted high dust collection efficiencies can be maintained. These rotary airlocks are common in Canada where there are extreme freezing conditions.

3. Dry Fog Dust Collector

Fog Dust collector systems were first used in the mining industry in 1995. Now it is widely used in cold regions; Dry Fog Dust collector systems are highly efficient, they use very little water, no chemicals and they don’t increase the overall dampness content of the flowing material. These dry fog dust suppression systems don’t create ice or freeze in cold climates which makes it perfect for winter conditions.

 

Dust control systems are needed all year round even in winter conditions. It is advisable to select the right dust control system/solution for the right weather conditions. Water-based dust control solution are not recommended during winter, it might be hazardous to the health of your workers.  Reach out to us today to develop the appropriate dust control solutions for your site.
