Venturi Type Wet Scrubber

Yes, high-energy venturi wet scrubbers are capable of capturing sub-micron particulate matter down to 0.3 microns with up to 99% efficiency by relying on extreme throat velocities to atomize the scrubbing liquid, creating violent collisions with the dust.

Because the Venturi throat accelerates gas to extreme velocities, the throat walls are subject to severe abrasive erosion. Maintenance involves periodic ultrasonic thickness testing of the throat walls and replacing the internal silicon carbide or ceramic wear liners before structural failure occurs.

To neutralize Sulfur Dioxide (SO2) in a wet scrubber, the recirculating water is typically dosed with an alkaline reagent such as Sodium Hydroxide (Caustic Soda, NaOH) or Calcium Carbonate (Limestone), which reacts with the SO2 to form harmless aqueous salts.

Aluminum and titanium dust are highly reactive and possess extreme Kst (explosion severity) values. Using a dry baghouse for these metals invites catastrophic deflagration. Wet scrubbers safely mitigate this risk by immediately encapsulating the volatile metal dust in water, suppressing any spark or explosion potential.
