Operating logic
The "LOTUS AIR" chlorine dioxide generator consists of the following main components: a production management tool,
4-filling level reaction tank, 2-filling level storage tank, HCl dosing pump, NaClO
2
dosing pump, chlorine dioxide dosing
pump, reaction tank emptying solenoid valve and reaction tank with water filling solenoid valve.
Note: during first startup
use water instead of chemicals (e.g.: priming, seal check, calibration)
Dioxide production cycle, the 7 main phases
Phase 1:
Activation of the water filling solenoid valve up to the first level in the reaction
tank. Disabling the solenoid valve.
Phase 2: Activating the pump to dose the HCl up to the second level in the
reaction tank. Disabling the pump.
Phase 3:
Activating the pump to dose NaClO
2
up to the third level in the
reaction tank. Disabling the pump and the instrument outputs.
Phase 4: 15-minute count for the chemical reaction and consequent production of chlorine dioxide.
Phase 5: Activation of the water filling solenoid valve up to the fourth level in the reaction
tank. (dilution)
All the levels must be reached in less than 60 seconds, otherwise
an alarm is triggered. Any alarm during this phase stops the procedure
and empties the reaction tank.
Phase 6:
Activating the emptying solenoid valve of the reaction tank and filling the reserve tank.
Phase 7:
Disabling the emptying solenoid valve until the product decreases to the last level in the reaction tank.
Once this operation is complete, the dioxide production cycle begins again and, depending on the setting
of the set-points, the dioxide dosing pump is activated to empty the storage tank.
