Spray tower scrubbers let gas and dust flows through a screen of sprayed liquid. This liquid is sprayed out of nozzles at the top of the scrubber. Meanwhile, the dust particles and other admixtures are captured by drops of the scrubbing liquid and settle on the scrubber. The cleaned air exits the machine back into the facility.
Water circulates in the scrubber. An SAS is added to the water: cations.
Coagulant: iron sulfate or iron chloride (III) and aluminum oxychloride (OXA) in the form of 30% solutions.
Starting reagent expenditure for formation of the filtration layer: 220-1100 lbs.
Then, according to the measurement data: up to 150 lbs/hour. Additional equipment
will be required to clean the water with a performance of 30 - 90 cfm.
The hollow scrubber successfully handled the objectives it's faced with at this painting site. It reduced the concentration of admixtures down to the level permissible according to sanitary norm values and has rendered the work area safe.
