PORTABLE VENTURI SCRUBBERS | VENTURI TECHNOLOGY

High-Energy Venturi Scrubbers

High-velocity spray venturi scrubbers are a traditional and well-known
method for removing fine dust particles from industrial air streams. 
Venturi scrubbers, (including ejector venturis and eductor venturis),
are often installed to remove fine particles from volatile, hazardous or
corrosive gas streams, or gas streams containing solid materials that
are difficult to handle.  They have been widely used throughout the
chemical industry for decades.

The collection efficiency and return-on investment realized with venturi
scrubbers are equal, in most cases, to that of a baghouse or electrostatic
precipitator.  Venturi scrubbers have a somewhat lower performance
efficiency, and (due to their use of high-pressure fans and other factors)
a significantly higher operating cost, than a cloud chamber scrubber.

10 Key Features and Benefits
of a Venturi Include:

• Venturi scrubbers collect coarse or fine particulate,
  including particulate under 1 micron and particulate that is
  sticky or high in moisture.

• Venturi scrubbers with a quench section (evaporative cooler)
  accommodate high temperature gas streams, including those
  from casting, sintering, glass  manufacturing, incineration
  and pyrolysis.

• Venturi systems can be used for applications with high dust loadings.

• Venturi scrubbers are suitable for variable gas flows.

• Venturi systems are continuously wetted, and are therefore not
  vulnerable to  clogging, plugging, scaling, or wet/dry line build-up.

• Collection efficiency for venturi scrubbers is 95-98.5%,
  (depending on whether they have three, four or five stages.)

• Slurries that contain high concentrations of solid material,
  or valuable material, can be recycled in venturi scrubbers.

• A mist eliminator module provides entrainment separation

• Venturi systems are custom manufactured in capacities to 300,000 cfm.

• Venturi scrubbers accommodate vertical or horizontal scroll outlet.
  

Venturi scrubbers are widely used to collect industrial emissions particulate. 
For applications (such as pharmaceutical manufacturing or laboratory gas
scrubbing) where collection efficiencies must be above 99%, however,
or where energy cost minimization is critical, a more prudent choice is
a cloud chamber scrubber.

Cloud chamber technology was initially developed for the collection of
submicron particulate from semiconductor manufacturing.  In these
applications and now in many others, a cloud chamber continuously
eliminates particulate down to 0.1 microns (and as large as 300 microns)
at efficiencies of 99.8% or higher.  Equally important, a cloud chamber
uses only a small fraction of the energy required for venturi scrubbers,
or devices such as electrostatic precipitators. (Click here for details.)

One additional consideration: venturi scrubbers cannot simultaneously
remove many common industrial fumes and gases, particularly those
that are insoluble. (Click here if your application involves HCl, HF,
HNO3 , H2SO4 , SO2 , Cl2 NH3 or similar gases.)
