How to remove dust from the air?
Airborne dust can be captured using a water spray. Water sprays have an inherent maintenance advantage over filter systems as they typically do not have to replaced frequently to maintain effective performance, low-pressure drops, and overall system performance.
The premise is that when a water droplet comes into contact with a dust particle, they will agglomerate and the resulting combination will be too heavy to remain suspended in the air stream.
The water droplet/dust particle combination will then fall out of the air stream where the dust can be disposed of.
To obtain the most effective dust removal, the droplets should typically be 1 to 5 times the size of the dust that is being controlled.
If the drops are too small, they will be unable to agglomerate with and knock down the dust particles. Conversely, water drops which are significantly larger than the dust particles from an air barrier around themselves, preventing the dust from gaining direct contact and encapsulation/agglomeration with the water droplet.
Nozzles can spray a fog of correctly-sized water droplets to remove the dust from the air.
We can provide droplet size distributions to aid in the selection of the correct nozzle and operating parameters.
Selecting Dust Control Nozzle
Normally, we used the ultrasonic atomizing nozzles for dust suppression, the situation includes movement of conveying, dump pits, air handling ducts and vents.
But in some special situation like fog cannon, the fine mist nozzle will be more efficient and convenient.
