TYPE OF EQUIPMENT:
Horizontal with three levels of filtering.
OPERATING PRINCIPALS:
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.
