Fume Hood Scrubber

Special features

  • Excellent removal efficiencies: Efficient counter-current gas/liquid contact results in 95-98% efficiency for most water-soluble acid and base laden airstreams.
  • Durable: Entire body of scrubber system made of chemical and corrosion resistant polypropylene.
  • Compact: The packing, spray manifold and mist eliminator counted on top of fume hood, pump and reservoir in the base cabinet. This arrangement ensures that minimal extra space is required for the scrubber system.
  • Floor standing & epoxy coated
  • Velocity control of approximately 80-100 feet per minute.
  • Semi close ventilated exposures.
  • Provided with sliding sash made out of special grade shatter proof glass duly framed in wooden/aluminum frame with sliding motion and counter weight balanced mechanism.
  • Illumination level of approx. 800 lux on the work table.
  • heavy duty exhaust system, comprising of dynamically balanced centrifugal impeller with high speed motor
  • suitable FRP ducting of required dimension as per the individual requirements

Mechanism

  • Drizgas Tech Fume Hood Scrubber provides excellent air pollution control for water soluble chemicals present in the laboratory fume hood exhaust fumes.
  • These Scrubber Fume Hood are designed to save space and provide effective air pollution control and operator safety protection for fume hoods.
  • Fume hood scrubbers can effectively reduce concentrations of certain water soluble acid, base and organic contaminants exhausted from a fume hood. If you are concerned about duct corrosion, hazardous stack emissions or other environmental factors associated with a fume hood you may want to consider a scrubber.
  • This is especially important for per chloric acid fume hoods, so as to prevent a build-up of potentially explosive perchlorate salts on the exhaust fan, as well as, on the exhaust ducting system.
    • Can handle air flow rate from 100 to 30,000 CFM
    • Removal method is Absorption / Chemisorption
    • Material of Construction: PP, FRP, PP+FRP, MS+FRP, SS 304, SS 316
    • High efficiency Tellerette®Tower Packing removes soluble/reactive gases, solid particulate and liquid droplets down to 7 microns
    • Lower shell serves as integral sump for recycle of liquid
    • Spray nozzles accessible from top of unit
    • Entrainment separators prevent liquid carryover
    • Special multi-bed packing designs accommodate different scrubbing solutions for removal of multiple contaminants

Working principle

  • Contaminated air from the fume hood enters the unit and passes through a packed bed then through the liquid spray section, a mist eliminator and then into the exhaust system for release outside the building.
  • The scrubbing liquor is recirculated from the sump and back to the top of the system using a pump. The air and the scrubbing liquor pass in a countercurrent fashion for efficient gas/liquid contact.
  • Water soluble gases, vapors and aerosols are dissolved into the scrubbing liquor. Removal efficiencies for most water soluble acid and base laden airstreams is 95-98%. Particulates are also captured quite effectively by this type of scrubber.
