Series 9000
Preformed Spray Scrubber
Overview
A major advancement in cyclonic scrubber technology, the Series 9000 Preformed Spray
Scrubber is capable of outperforming venturi scrubbers on an energy cost basis for
collection of particulate in the 2 micron and larger size range and simultaneous removal
of gaseous pollutants.
The Series 9000 incorporates a unique specially designed gas entrance involute section
fitted with proprietary reverse jet sprays for concentrated and rapid treatment of dust
particles and fumes. Access to and ability to service the spray components from the
exterior of the scrubber eliminates the inherent maintenance problems and
resultant downtime as with conventional spray scrubber devices while achieving
a major increase in collection efficiency.
The completely unobstructed open design of the scrubber vessel eliminates
solids buildup and required cleaning, maintenance or replacement of internal
packing elements, turning vanes or mist eliminator components. Furthermore the
Series 9000 is extremely compact enabling installation in limited height locations.
Versatility of the Series 9000 Preformed Spray Scrubber can be extended
to handle varying gas flow volumes with incorporation of an optional
variable area inlet vane assembly.

How it Works
Contaminated gas enters the long narrow involute (1) and is horizontally
accelerated through a concentrated zone of sheared reverse jet spray
(2). In this zone, the hydraulically atomized extremely fine droplets of
scrubbing liquid at high relative velocity collide with the oncoming gas and
impinge with the particulate.
Any water soluble gaseous pollutants present are absorbed by the millions
of created spray droplets. This combination of the unique involute and spray
zone design generates a fierce scrubbing action that eliminates bypass and
escape of untreated contaminants. The particulate contained liquid droplets
agglomerate in the final section of the involute (3) and undergo an initial separation
from the gas stream before entering the cyclonic entrainment removal section.
Without the need for internal baffles, plates or vanes the high efficiency involute
design creates a positive centrifugal action to remove the majority of droplets
from the gas. The gas then enters into the cyclonic separator section (4) where
spinning forces the remaining entrained liquid droplets with pollutants to
separate from the gas through impaction and collection on the scrubber
interior wall, gravity draining into the sump section (5). The cleaned gas free
of moisture droplets exits the top of the unit (6).
