TYPE OF EQUIPMENT:
Venturi tower scrubber with integrated fan
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 opening 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 wash tower
through the reagent recirculating tank. In the tower, the air is backwashed
again at a low velocity over a large contact area. Exhaust air is then released
into the atmosphere through the fan integrated in the tower. Demisters (alveolar
packs to separate droplets) are inserted in the tower to eliminate liquid
carry-over.
