TYPE OF EQUIPMENT:
Venturi tower scrubber.
OPERATING PRINCIPALS:
Pollutants in the air treated by the ecochimica® SCRUBBER are
absorbed by chemical reaction through washing with reducing reagents. The
standard scrubbers produced by ecochimica® are double-stage to ensure greater
efficiency and to guarantee emissions within ever more restrictive legal
standards.
First Stage (Venturi):
Incoming contaminated air is drawn into the scrubber through
the venturi where, because of the strong turbulence created in the throat
by high velocity, it is forced into contact with the wash solution providing
optimal pre-treatment conditions.
Second Stage (tower):
The contaminated air passes from the venturi to the tower through
the reagent recirculating tank. In the tower, the air is backwashed again
at a low velocity over a large contact area. Demisters (alveolar packs to
separate droplets) are inserted in the tower to eliminate liquid carry-over.
Air is pushed through the scrubber by a standard fan and once treated is
released into the atmosphere.
