We also offer "Dry Fog"
type dust suppression in technical collaboration
with Churchill Environmental Engineering Ltd.,
UK. This type of system is particularly suitable
for enclosed material handling plants where
the addition of moisture has to be kept to
an absolute minimum. This method uses water
and compressed air to make micron sized water
droplets that are able to suppress respirable
dust without adding any detectable moisture
to the process.
Air assisted atomizing nozzles:
We use ultrasonic atomizers which atomizes
the liquid using a compressed air supply that
is capable of producing extremely fine droplets.
Ultrasonic atomizer works through a two-step
process:
Step 1: Liquid is injected through
a number of small orifices into the nozzle
outlet channel, where a high velocity air
stream provides the first liquid breakup.
Step 2: The air stream carrying the
droplets impacts onto a resonator placed in
front of the nozzle outlet orifice, generating
a field of high frequency sound waves. Flying
through the sound wave field, the droplets
undergo an additional breakup step.
