4.3 Principles of Operation
This product is designed to capture potentially combustible dust particulate from certain industrial applications using a wet filtration process. When operating,
air and dust is drawn into the table, passes through installed ducts, into the Wet Dust Collector’s filtration system, and then finally exhausted out the top
discharge. The agitation of water creates a humid environment within the collector, trapping the hazardous dusts, which will settle in the bottom of the basin.
This product consists of five basic components:
1.
A cabinet for housing all components
2.
A motor blower assembly
3.
Electrical assemblies
4.
Collecting assemblies (filters pad and water)
5.
Downdraft table (optional)
During the normal operation of the wet collector, shop air is drawn into the collector. As this air passes through the collector’s water it removes some water
in the form of humidity and over a period of a few hours this results in a drop of the collector water level. The WX-series of collectors rely on a sophisticated
ultrasonic control system to continually monitor water levels and refill automatically the collector on-line. In addition, the controls support
1.
High water alarm
2.
Low water alarm
3.
Blower shut down in case of alarms
4.
Interface for Photohelic (Included with HEPA option)
5.
Interface for temperature sensors (Included with HEPA option)
6.
Interface for auxiliary vent fan
7.
Current sensing/alarm for auxiliary vent fan
8.
Master / Slave input for scrubber to run when dust producing equipment is “on” (may require additional hardware)
9.
PLC LCD display showing water level and alarm conditions

As soon as the start button is pressed, the main motor will start if no alarm conditions are present and will run until an alarm occurs or the stop
button is pressed. If connected, there is also a remote control input on the PLC that can trigger the Star/Stop command. Note, the controls at the
front of the panel will have priority on the machine state for safety reason. (ex. The remote control has started the machine but, if the stop button is
pressed, the machine will stop). Meanwhile, the machine will try to maintain the water level to a set water level while running and while stopped.
When the machine is stopped, an exhaust fan will start running.
As soon as the machine is powered, the water level is monitored through an ultrasonic sensor. The machine is designed to operate at a level set
on the interface by the factory. When the water level reached a certain difference with the set point, the water valve is opened and the machine
begins to fill up. When the water level reaches the set point value, the valve is closed.
A low and high water level has been factory set and the alarms will activate when either of those levels are reached. As a result, the machine will shut
down and won’t restart as long as the alarm condition persists.
