Fog cannon dust suppression is a mist cannon that is engineered smartly to combat air pollution.
The device reduces the airborne dust and other particulate matter by spraying a fine mist of water into the air.
What are the applications of Fog cannon dust suppression?
Fog Cannon dust suppression is used commonly in areas where dust generation is a significant concern. It is used in various industrial and construction settings like mines, quarries, demolition sites, and material handling facilities. They are also used in agricultural activities and for controlling pollution in urban areas.
What are the benefits of mist cannon?
- Improves the quality of air
- Enhanced worker safety
- Protection of equipment
- Enhances the visibility
What is the science behind the working of Fog Cannon dust suppression?
The science behind the working of this device revolves round the principles of agglomeration and gravity setting.
- Creation of mist: Water is pumped out through a series of nozzle at high pressure. The nozzles are designed to produce a fine mist of water droplets. The size of these droplets is important for the effective dust suppression. Normally the droplets are in the range of 10 to 150 micrometers in diameter. This size range is optimal for interacting with a wide range of dust particle sizes.
- Agglomeration: It is the process by which the water droplets from the fog mix with the dust particles in the air. When the water droplet comes in contact with dust particles it can encapsulate the particle, enhancing its mass. If this droplet collides with a dust particle that is wet, combine and form larger heavy particle. This process is efficient when the size of water droplets and dust particles are matched closely.
- Gravity setting: Once dust particles are combined with water droplets, their increased weight makes them unable to remain airborne. Under the influence of gravity, these heavy and clustered particles settle to the ground. This removes the dust from air, minimizing the concentration of airborne particulate matter.
- Evaporation: The fine water droplets evaporate after they have settled the dust, especially in the environments where water conservation is important or where added moisture can be an issue.
- Airflow: Dust suppression is effective when the fog cannon is able to distribute the mist across wide area and in right concentration. This involves adjusting the angle of the cannon, pressure, and rotation to make sure that mist covers the entire dust producing area. Some cutting-edge fog cannons are equipped with fans to help disperse the mist more evenly and enhance its reach.
With the blend of the above scientific principles fog cannons effectively suppress dust and combat air pollution.
