Removal and suppression of explosive dust with both wet and dry collection technologies

Have technical questions about Explosive Dust Collectors?

Ask A Monroe Expert
Monroe Environmental has extensive experience with explosive dust collection. We offer both wet and dry collection solutions depending on your specific application. Our wet collectors suppress and neutralize the explosive qualities of the dust, rendering them non-combustible. Monroe dry collectors utilize the latest NFPA approved explosion protection components to both prevent explosions and minimize their effects.

Wet or Dry Collection?

Several factors must be taken into account before selecting the best explosive dust collection method. Both wet and dry systems can be utilized depending on the physical properties of the dust such as particle size, moisture content, ignition potential, and dust concentrations. The Kst and Pmax values of a particular dust helps to classify the severity of an explosion should it occur. The higher the Kst vlaue, the more severe the explosion.

In general, wet collection systems suppress and neutralize the dust’s explosive properties so that it no longer poses an explosion threat. Additionally, wet systems can better handle highly abrasive dusts that may tear, shred, and damage dry filter media. However, by design these wet systems consume fresh water and generate wastewater that must be treated, impacting the operating cost of the units.

On the other hand, dry collection systems are designed not only to prevent explosions, but to contain and minimize the dangerous effects of explosions should they occur. Dry collectors are often required to have several mechanical instruments and fire suppression components such as explosion vents, spark arrestors, backdraft dampers, smoke detectors, and emergency sprinkler systems which can significantly impact the cost of the unit.

In general, the following application and site data should be taken into account at a minimum when determining the best solution for explosive dust collection:

  • Process to be exhausted
  • Physical properties of the dust
    • Particle size, shape, and concentration
    • Moisture content
    • Ignition sources/potential
    • Kst and Pmax values
  • Site layout, ductwork, and enclosure/hood design
  • Water sources
  • Wastewater treatment/disposal capabilities
  • Worker exposure and safety

Wet Dust Collectors for Explosive Dust

Dual Throat Venturi Scrubber

Dual Throat Venturi Scrubber – Wet Dust Collector

The Monroe Dual Throat Venturi Scrubber is a wet type dust collector that provides efficient collection and suppression of explosive dusts for a variety of applications. It is designed to provide continuous-duty collection and removal of airborne dust and particulate matter produced by manufacturing and processing operations at 99+% efficiency on many installations.

The Dual Throat Venturi Scrubber contacts the dust with water to reduce its explosion potential and transfer the particulate into the water stream. The water droplets and particulates are then removed from the air stream through separation, baffling, and mist elimination stages. This unit is excellent for explosive dust applications.
