Particle-laden
air flow is
forced
through the
narrow
throat
section of
the venturi
scrubber to
move at a
relatively
higher
velocity. In
the
meantime,
water is
introduced
into this
throat and
the high
velocity gas
shears it
into small
droplets
serving as
targets for
particle
collection.
The water
droplets
incorporating
pariculate
matter are
collected
after
leaving the
throat and
then
diffuser of
the venturi.
The widely
used
equipment
for this
purpose is
cyclonic
seperators
which
permits good
seperation
of these
droplets
from the gas
stream
through
centrifugal
forces. The
particle-free
gas leaving
these
cyclonic
seperators
is released
into the
atmosphere. |
