Things You Want to Know about Fog Cannons

Fog cannons (also known as spray guns, dust suppression cannons, emission control units, dust fighters etc.) serve for effective spraying of water.Fog cannon makes fine mist that is driven by strong air flow generated by a powerful fan. Mist reach depends on wind speed and direction.

Simply put, a fog cannon uses high-pressure water, pumped through a series of nozzles, to turn the water into fog through atomization. This fine mist is dispersed through the air by a powerful fan.

How does the fog cannon work?

Each fog cannon has its own generator and is mounted on a skid that can be moved depending on weather conditions and the type of dust being generated. Once connected to a water source, they are ready to be used.The fog cannons are strategically placed near dust sources, such as open tip areas, haul roads or loading areas. When dust particles hit the fog, the particles are captured and the water dissipates before it has a chance to spread.

Fog cannons can come in a variety of sizes and with different throw ranges. Cannons can also be fixed or oscillating. For example, a cannon may have 20 to 25 nozzles with a range of up to 80 meters, each using 3 liters of water per minute and oscillating at 140 degrees.

 Fog Cannon

The cannon can be activated manually or remotely when large amounts of dust are generated and when combined with certain weather conditions. The amount of water used by the cannon can also be fully controlled to optimize water consumption.

The key to the success of a fog cannon is not just how much water the cannon can spray or how far the water can reach. Nozzles need to be strategically selected to release the correct size droplets of water into the air for each operating condition.

What are the benefits of fog cannon dust suppression?

The key criteria for considering the benefits of fog cannon dust control are the reduction of the amount of water used in the dust suppression system and the elimination of residues. The advantages of using fog cannons for dust suppression depend largely on the application.

1. Reduced associated costs

With a fog cannon system, you can use water more strategically and reduce the associated costs. Reduced stormwater impact and runoff, which is critical to maintaining a balance of air and land pollution. Fewer ponds to ensure a safer, more efficient site.

2. Avoid product oversaturation

Fog cannon dust suppression prevents product oversaturation, which often creates sludge that is difficult to handle and sticks to facility surfaces and equipment, shortening the life of both. Water flow can be adjusted to regulate the amount of water discharged from the fog cannon to control surface dust and airborne dust without saturation problems.

 Applications for Fog Cannon    3. Movable

Fog cannons can be set up in fixed or mobile locations depending on site-specific needs. Fog cannon dust suppression has contributed to the popularity of wet dust suppression options. They are very effective and are quick and easy to implement. Providing a long-term solution, they can provide years of trouble-free performance with regular maintenance.

Effective applications for Fog Cannon include.

Industrial and wildfire suppression, where it is very effective.

Airport, highway and tunnel fire and/or smoke evacuation.

Solvent diffusion to prevent spills into the environment.

Coal handling & power generation

Wood processing

Watering (golf resorts, gardening)

Chemical spraying (gardens, mosquito areas etc.)
