TYPE OF EQUIPMENT:
Horizontal with three levels of filtering.
Pollutants in the air treated by the ecochimica® SCRUBBER are absorbed by chemical reaction through washing with reducing reagents. The horizontal scrubbers produced by Ecochimica® are triple-stage to ensure greater efficiency and to guarantee emissions within ever more restrictive legal standards. Ecochimica® can manufacture two-stage horizontal scrubbers on request.
First stage (acid):
The intake air is washed on a large static contact surface (air and wash solution), passing horizontally over the capturing components sprinkled from above with an acidic solution with a pre-determined pH. The air then passes through demisters (blades which separate droplets), which remove excess reagent before passing on to the second stage, avoiding liquid carry-over.
Second stage (basic + oxidant):
Air from the first stage is washed a second time with the same process, with an oxidant in a basic solution with a predetermined pH and oxidation-reduction potential. The air then goes through appropriate demisters before passing on to the third stage.
Third stage (basic):
Air from the second stage is washed with a basic solution with a predetermined pH and then passes through appropriate demisters. Air is pushed through the scrubber by a standard fan and once treated is released into the atmosphere.
