Process Air Gas Silencers

Process Air Gas Silencers

Typically utilized for rotary blades or centrifugal blowers, Wakefield Acoustics offers a wide range of custom-designed process air or gas silencers. Each silencer is cost-effectively designed to meet the most demanding of customer noise specifications.

We offer several type of absorptive silencer construction dependent on application and structural requirements, from light gauge welded construction through to heavy plate welded construction.

INDUSTRIAL SILENCER
Dependent upon the level of acoustic performance required silencers can be designed with an absorptive outer layer, thus not presenting additional pressure onto the system. Where a high level of noise reduction is required, a central acoustic pod would normally be installed.

Given the high heat levels which can sometimes be generated in process air and gas lines, the silencers would normally be treated with a heat-resistant paint finish after fabrication.

Wakefield Acoustics is able to undertake pressure testing of silencers to ensure compliance with project requirements.

Pickle Line Fume Exhaust

Pickle Line Fume Exhaust

Busch

Modern steel mill pickle lines utilize Hydrochloric Acid to clean the surface of the steel sheet. Acid mist and fumes are generated during this process.

Busch, and our sister firm HEE-Duall, provide complete fume scrubbing systems to capture and neutralize this acid fume. Our systems begin at flanged connections to the pickle line tank covers. A fiberglass duct connects the tank covers to the scrubber and fan, which exhausts to the outdoors by means of an exhaust stack.

The Pickle Line Scrubber is a counter current packed bed scrubber consisting of packed tower complete with flanged horizontal radial gas inlet, glass-filled polypropylene random packing. This allows for excellent mass transfer resulting in high efficiency capture of HCl fume at a minimum pressure drop.

  • The scrubber housing incorporates a vertical or horizontal outlet flange to facilitate installation in limited space.
  • The packing is irrigated by internal piping and liquid distribution system.
  • HCl is scrubbed by using a re-circulation wash water solution from integral self-contained re-circulation tank at the bottom of the scrubber.
  • Blow-down from the re-circulation system serves as make-up water to the pickle line.

We deliver top-performing mist eliminators with optional internal spray piping and spray nozzle to intermittently wash the underside of the mist eliminator, triggered by either high-pressure differential or on a timed sequence.

The cleaned gas from the scrubber is sent to a System ID fan via an interconnecting duct and then to the stack. Click here to download our Steel Brochure.

Note: Acid storage tank vents may also be connected to the system.

Materials of Construction:

  • Scrubber Vessel – FRP or PVC
  • Random Packing – Glass filled Polypropylene
  • Internal Piping and Liquid distribution system – CPVC

Packed Bed Spray Nozzle (Spray Nozzles for Wet Packed Bed Scrubbers)

Packed Bed Spray Nozzle (Spray Nozzles for Wet Packed Bed Scrubbers)

HEE-Duall

Choosing the Best Spray Nozzle

A properly designed Wet Scrubber removes a variety of air contaminants. Wet Packed Bed Scrubbers remove air contaminants and impurities by washing the airstream with a water liquid. Air contaminants are removed by the scrubbing liquid by impaction, reaction with a chemical solution or absorbed into the liquid. Air contaminants and the scrubbing liquid come into contact with other in the packed section of a wet scrubber filled with a high efficiency packing. Spray nozzles will spray small droplets and evenly introduce the scrubbing liquid above the packed bed section, which then flows down through the packing to the bottom of the scrubber sump. A mist eliminator section located above the spray nozzles removes liquid entrained in the cleaned exhaust airstream prior to entering the atmosphere.

Spray nozzles are selected at the lowest possible operating pressure to produce a uniform spray pattern with larger rather than smaller droplets. Any liquid particles that become airborne but do not wet the packing surface defeats the purpose of a scrubber. The function of the spray nozzle is to distribute liquid over the packing, not to test the operation of the mist eliminator. While the mist eliminator will capture the larger airborne droplets, agglomerate them and eventually drain back down to the packing, we do not want 80% of the liquid volume heading to the mist eliminator but instead onto the packing area. Selecting a spray nozzle with a larger particle size without creating a significant amount of smaller droplets than can become airborne and operating at lower operating pressure would be a better choice. In general, spiral spray nozzles should be avoided.

FEATURES & BENEFITS

Several common spray nozzle types are candidates for use in a wet packed bed scrubber:

  • Spiral spray also nozzles (TF and TFXP), also called pigtail nozzles producing a round spray pattern
  • Full cone clog resistant nozzles (MP) giving medium to course droplet size
  • Full cone whirl nozzles (SC and NC) with course atomization, available in round and square spray patterns
