V-tex™ achieves high removal efficiencies
through our detailed understanding of vortex flow
and process intensification.
For gas cleaning
The gas enters the body of the scrubber tangentially
and increases in velocity as it spins toward the
centre.
At the centre of the chamber are two opposed nozzles
through which the scrub liquor is sprayed. Where
this liquor impacts, it shatters into millions
of tiny droplets which are thrown outwards toward
the edge of the chamber. This provides a high
droplet velocity relative to the gas and a very
high surface area for gas/liquid contacting. The
diffusional path of droplets from the centre of
the chamber to its outer walls is long. This means
that the droplets are in contact with the gas
for the maximum possible time thus creating highly
effective scrubbing efficiencies.
The deluge of droplets absorb the contaminant
from the gas as they travel through it, eventually
hitting the outer wall of the chamber where they
fall into the sump at the base of the unit. The
intensity of the gas/liquid contacting is maintained
by the pumped liquor being continually re-circulated
from the sump and sprayed throughout the system.
This ensures that high turndown ratios are continually
achieved.
The clean gas exits the V-tex™ system through
a hole in the ceiling of the chamber.
For liquor cleaning
Where a liquor has a contaminant that requires
removal V-tex™ works in reverse to the way
described in gas cleaning.
The clean gas enters the body of the scrubber
tangentially and increases in velocity as it spins
toward the centre.
The contaminated liquor enters the chamber through
two opposed nozzles at its centre. Where this
liquor impacts, it shatters into millions of tiny
droplets which are thrown outwards toward the
edge of the chamber. This provides a high droplet
velocity relative to the gas and a very high surface
area for gas/liquid contacting. The diffusional
path of droplets from the centre of the chamber
to its outer walls is long. This means that the
droplets are in contact with the gas for the maximum
possible time thus creating highly effective scrubbing
efficiencies.
The clean gas absorbs the contaminants from the
spray as it travels through it, the cleaned liquor
falling into the sump of the V-tex™ system
where it is either drained away if the correct
contaminant removal; levels have been achieved,
or recirculated through the nozzles for further
cleaning. The gas exits the V-tex™ system
through a central point in the ceiling of the
chamber.
Due to the fact that the nozzles are directly
opposed the V-tex™ system will not become
blocked as any contaminant larger than the nozzle
size will be broken down into smaller particles
by the force of the spray from the nozzle directly
facing it. The system is therefore largely self
cleaning and maintenance free.
