High-Efficiency Cleaning for Tough Industrial Dust & Fumes

Imagine needing to remove extremely fine dust, smoke, or mist – particles so small they are invisible to the naked eye (sub-micron) – from factory exhaust before it enters the atmosphere. That’s where Ducon’s Venturi Scrubber comes in. It’s a highly effective wet cleaning system designed for superior particle removal.

How Does It Work Simply?

Our Venturi Scrubber uses a clever, powerful process:

  1. Speed Up the Gas: Dirty exhaust gas is funnelled into a narrowing section (the “converging” section), making it speed up significantly.
  2. Introduce Water Smartly: As the gas speeds through the narrowest point (the “throat”), scrubbing liquid (usually water) is introduced along the walls using a special “weir” system. This avoids using spray nozzles that can easily clog.
  3. Turbulent Mixing: The high gas speed violently tears the water into millions of tiny droplets, creating intense turbulence. This forces the fine pollutant particles to collide with and get captured by the water droplets.
  4. Slow Down and Separate: The gas-water mixture then enters a widening section (the “diverging” section) where it slows down. This allows the now heavier, pollutant-laden water droplets to be easily separated from the clean gas using downstream equipment like a cyclonic separator or mist eliminator.

While Venturi Scrubbers *can* remove some gas pollutants, their main strength and most efficient use is capturing fine particulate matter.

Key Advantages of Ducon Venturi Scrubbers:

  • Exceptional Cleaning Power: Achieves over 99.9% collection efficiency, even for very fine sub-micron particles.
  • Reliable Operation: Our unique “wetted wall” inlet and weir liquid distribution prevent the common problems of wet/dry buildup and nozzle plugging.
  • Low Maintenance: No spray nozzles means fewer plugging issues and easier upkeep. Simple water level control is not required.
  • Handles Tough Conditions: Designed to work effectively with high gas temperatures and heavy dust loads.
  • Flexible Performance: Can be designed for specific pressure drops (up to 80 inches W.G. or more) to meet required efficiency. Adjustable throat options are available (manual or automatic) to handle varying gas flow rates or future needs.
  • Handles Slurries: Can effectively use recycled scrubbing liquids containing high levels of solids.
  • Durable Construction: Built for long service life, available in various materials (like Stainless Steel, Hastelloy, Inconel, FRP, or lined steel) to resist corrosion and erosion in demanding environments.
  • Environmentally Sound Choice: Effectively removes pollutants from air streams, helping facilities meet environmental regulations and reduce their impact.

Ideal Applications:

  • Removing fine dust from industrial processes
  • Controlling fumes and aerosols
  • Cleaning exhaust from dryers, kilns, and furnaces
  • Applications requiring very high particle removal efficiency
  • Processes with sticky or abrasive dust
  • Situations where simple, robust operation is key
