Crossflow Industrial Wet Scrubber

System design, supplied components, optional features

Industrial Scrubber

 

Tri-Mer Crossflow industrial scrubbers have two stages. The first stage removes most contaminant from the air stream and may be continuously wetted to prevent plugging. Stage two is a mist eliminator.

Crossflow Design

  • The Crossflow Wet Scrubbers shell are manufactured of Polypropylene, Polyvinylchloride, (PVC) Stainless steel or Mild steel. Vendor shall evaluate contaminants and select the most appropriate material for this service.
  • The Crossflow Wet Scrubber shell is provided with access ports / doors to allow limited access to the internals of the unit. The Scrubber shell is equipped with flanged pipe connections or female NPT connections for the introduction of makeup and drain water as well as various types of level control, pH fittings, and recirculation liquid connections.
  • The Crossflow Wet Scrubbers is equipped with random dumped Tri-Pack packing. The depth of the packing is determined per application by Tri-Mer Corp.
  • The Crossflow Wet Scrubber is equipped with a high efficiency (95% @ 15 micron and larger) mist eliminator of the chevron blade type or a coalescing type mesh pad. (99% @ 10 micron and larger mist.) Material of construction for the mist eliminator is PVC or polypropylene; alternate materials are available.
  • The fan, if optioned, is manufactured from FRP, PVC/PP with coated steel impeller, stainless steel, or an equally suitable material.
  • The fan and motor is designed for system static pressure per application depending on packing depth and mist eliminator selection. Pressure drop calculations through the Scrubber plus external delta P for the customer’s ductwork losses.
  • The sound levels generated during normal operation shall not exceed 85 dba-weighted, slow response, under free field condition, at a horizontal distance of 10 feet from the surface of sound generation.
  • Vendor shall provide electric motor drives for each fan. Vendor shall be responsible for the selection of the motor characteristics and the motor mounting.
  • All electrical equipment provided by the vendor shall be supplied in NEMA rated type enclosures.
  • All equipment manufactured by Tri-Mer Corporation is warranted under the standard Tri-Mer Corporation one-year warranty. All purchased components are warranted under the respective manufacturer warranty.
