DRY FOG (DOUBLE FLUID) DUST SUPPRESSION SYSTEMS
Ultrasonic atomizers operate in a complex structure; In the first step, the water jet is injected into the high speed air stream, where the initial breakdown of the liquid takes place. In the second step, this biphasic flow formed is directed to the region where the sound waves are located, and secondary splitting ensures minimal droplets to form. This is accomplished with the resonator placed in front of the orifice. The droplets of the mist cloud formed are about 30 microns.
DOUBLE FLUID ULTRASONIC NOZZLES
Ultrasonic atomizers have a complicated working principle; At the first step, water jet is injected to the high velocity air and the first fragmentation of water happens. At the second stage, this two-phased fluid is led to another zone and water is crumbled into very small drops (about 30 microns) via sound waves. This is done by a resonator mounted before the orifice.
PLC - SCADA SYSTEM (OPTIONAL)
SCADA screen on the automation system makes it possible to control and monitor system parameters. The system functions are listed below:​
​
-
It notifies the operator about the malfunction and solution methods in case of a malfunction.
-
Water tank supply line flow and water tank level can be monitored.
-
Sediment and mud accumulated on the bottom of the tank can be monitored via mud sensor and discharge process of mud and sediment can be controlled.
-
Monitoring water flow from water tank to centrifugal pump.
-
Monitoring centrifugal pump status (flow – non-flow).
-
Monitoring the status of automatic back-flush filters, (back-flush is running).
-
Monitoring water supply from disk filters to high pressure pump.
-
Monitoring high pressure pump.
-
Monitoring pressure at the outlet of every proportional ball valve on the collector that distributes water coming from high pressure pump to different points.
-
Pressure and flow rate at every line can be controlled by means of controlling electric actuated proportional controlled ball valves.
-
Indicating a clogging at the secondary filters.
-
Winter and summer mode can be switched on/off.
-
When the winter mode of the system is selected, the system will not be started in one minute after it is stopped, water discharge process with pressurized air automatically starts for preventing water freeze and damage to the system. This process can be monitored from the SCADA screen.
-
SCADA system warns the operator via warning lights and audio in case of a malfunction when the system equipment has water inside or air discharge cannot be completed.
-
System software allows a authorized supervisor to monitor and print a report of on-off times, daily and hourly water consumption of the system. System does not let anyone except the supervisor to reach, copy or delete these data.
-
​Dust suppression system measures instantaneous dust amount in the air and records with date and time if the amount of dust is measured above limits. This situation is also recorded by a camera mounted on the system. System does not let anyone except the supervisor to reach, copy or delete these data.
