RELIABLE & RUGGED DUST SUPPRESSION SYSTEM FOR CORE SECTOR
AUTOMATIC DFDS SYSTEM (DRY FOG DS SYSTEM)
Non electrical spray actuator (FAV-100-Flow Activation Valve) for conveyor belt transfer points (DFDS) built-in water supply valve in the equipment, which opens only on rotation of wheel and will spray only when belt is moving with load and stops spraying when belt is stationary, equipment operates only when belt is in contract with conveyor belt, however light is the load on the belt.
MAKING SURE THERE IS NO WASTAGE OF PRECIOUS WATER. (SPRAYS ON LOADED BELT)
No electrical cabling / no solenoid valve(power saved = power produced)
No laying of cabling (save in extra installation cost)
No extra power supply is needed to operate the system.
Automatic activation of system (on/off)
No man power required to activate system (will start with belt motion)
100% fail-proof (mechanical-activation)
Operates at belts speed from 100ft/min to 750 ft/min. maximum working pressure 105 bar.
No chemicals is used
Best performance can be expected for DFDS Water pressure max 1 bar & air 3.5 bar.
Avoids over wetting of belt, which causes slipping & over maintenance in all stage.
System can be installed in maximum 4hrs time without any modification.
Space required is under the belt, no ducting, & installation of bag / filters etc.
Engineered system & custom designed to every specific need.
Reduces periodical clean-up & system failure.
Maximum return on investment (years of trouble free service)
Minimum maintenance / operating cost / downtime (more – production / cleaner environment)

SYSTEM DESIGN
CONTROL PHILOSOPHY
.hmc. conflow code-100 Dry Fog Dust Suppression System operates with compressed air & water synchronized through a twin port nozzle atomizing water into a mist of microscopic particles.These droplets agglomerate join with the airborne dust, increasing weight so the combined particle settles back into the main material stream. .hmc. Conflow code-100 Dust Suppression System eliminates fugitive dust emissions from material handling and processing.
Specially designed AIR & WATER sonic atomizing nozzle with code-100 (air) mechanical controlled valve is allowed to shears water into droplets of the desired size.
DS system has a special sonic nozzle with inbuilt anti drip valve, connected directly to the water line. The activation system is the code-100 (as shown in anx-1-enclosed) The code-100 controls the inlet of air to activate the DS System. With the slightest of load on belt the valve will open and allow passage of air to the nozzles, (minimum 5 bar)
The air push the anti drip valve in the nozzle and allow water and air to mix creating fine droplets of fog.
To control the nozzle (start stop the spray) it is the air line that requires signaling, due to the nozzle valve holding the water at the nozzle without dripping, as soon as the air is turned on (usually via code-100 (mechanical sensing system) linked to conveyor start etc the valve opens and lets air through atomizing into micron droplets, as the air is an open circuit.
When the air is stopped, the opposite happens and the valve closes again reducing from 5 bar operating pressure to 0, at 2.5 bar the water valve closes, stopping the water ans as the air reduces from 2.5bar to 0 it blows the nozzle tip clean and purges itself, therefore every time the nozzles stops spraying, it cleans itself. (Self cleaning nozzle without any separate solenoid valve + electrical cabling etc)
It adds only minimal water to avoid material degradation. With the small droplets size and the fog’s effective dispersal pattern, moisture addition is approximately 0.1% by weight of material conveyed.
IMPORTANT ADVANTAGE
Minimum addition of moisture on material
0% maintenance against electrical conventional dry fog system
(such as unreliable solenoid valve/cabling leakage / electrical sensing)
100% atomization
Mechanical sensing unit (100% fail-proof)
No electrical cabling required to activate system (No energy power consumption)
Operates at belts speed from 100FT/MIN to 750 FT/MIN, Maximum working pressure 105 bar
