use of scrubbing towers aims to prevent the diffusion in the atmosphere
of noxious acid vapors coming out of processes utilizing acid substances
(galvanic processes, glass etching processes, etc.).
is made up of a washing scrubbing tower with cylindrical section, dimensioned
for the given air flow to be treated and for the corresponding air speed,
inside the tower, suitable for the process.
is entirely made in PP, with a bearing base acting as washing recirculating
liquid tank, opportunely strengthened and supplied with needed charge
and discharge connections, overflow, level, inspection door for reagents
loading, recirculation pump.
column is supplied with one or two PP grids sustaining Eco-rings, sprayed
from above with a water rain, coming from a group of PVC nozzles, fed
by a piping system in PVC.
acid vapors, after having gone through the rings in counter current with
the washing water, is attacked by a water nebulization produced by the
sprinkling system where vapors undergo a further washing.
phase, air go through the drops separator, which has to keep water particles
in suspension, avoiding water dragging out of the tower.
is supplied with porthole for rings loading/unloading and for nozzles
maintenance, and with air inlet and outlet.
pump, which has to recirculate the liquid within the column, is made in
PP. It has vertical axis, and it is lodged in the lower part of the tower
acting as tank,.
fan, outside the scrubbing tower, guarantees the needed suction level.
The fan is made in polypropylene, its capacity and head are established
in the design phase to satisfy the specific requirements.
could have just one tower or two towers in series, according to the characteristics
of the air to be treated and to the requested emission level in the atmosphere.
