Industrial dust collection products when integrated into complete systems, remove industrial contaminants from polluted air streams prior to atmospheric discharge, and when feasible, allow the return of cleaned air back into the manufacturing facility. Which type of industrial dust collector you choose and the final system design, will depend on the collected particulates physical and chemical characteristics and the process exhaust conditions.

Industrial Dust Collection System Benefits


Benefits of an effective industrial dust collection systems include:

  • Employees are protected from the harmful effects of pollution with an effective industrial dust collection system.
  • Industrial dust collectors keep facilities compliant with health and air emission regulations.
  • Use of industrial dust collection systems protects the environment from pollutants from manufacturing processes.

 

Key Factors for Dust Collection System Design


There are two key areas we focus on when reviewing a new system layout. First, the geometry and chemistry of particulate in the air stream which determines the way we configure and select components. Clean air system flow control components such as multibladed dampers on the “dirty side” can no longer be used as they would gum up or fail prematurely. The second key factor is keeping particulate in suspension after it is collected and effectively conveying it to the filtration device. Should equipment slowly fail or breakdown, particulate settling in the duct creates potential duct collapse, leaks in the duct, fire and explosion potential, additional static pressure loses with increases in fan horsepower, fan wheel abrasion, and imbalance.

Our systems approach is divided into two categories:

Ducted Pollution Control Systems – These systems are often termed central systems meaning the pollution control device or dust collector is located away from the process collection point and a duct system conveys the material to the air cleaning device. It is critical when evaluating systems that all the components included are of equal quality and value. The major components would include the dust or mist collector, capture hood (s), conveying duct, flex connector (s), fan damper, and HEPA filter assemblies. Also, duct layout, start-up and commissioning services, and controls need to be closely evaluated.

Self-Contained Dust Collectors – Self-contained dust collectors are a “complete” system by design, in that they include all the items included in a ducted system, but without the duct. These would include smaller cartridge and envelope bag collectors, portable dust collectors, downdraft benches, downdraft tables, portable equipment, and environmental control booths.

SysTech has developed quite a few systems since 1985. We configure industrial dust and fume collection systems using quality components and the proper materials of construction.  Examples are:

Dust Collection System Design Considerations


Dust, fume and mist collection system design is about:

  • Maintaining airflow thru system to minimize particulate and material deposition
  • Minimizing noise levels from components
  • Minimizing the pressure loses thru the system with proper duct and fitting configuration
  • Minimizing horsepower requirements
  • Maximizing capture with hoods with correct airflow
  • Maintaining the integrity of duct and components by selection of proper materials of construction

Typical Dust Collection System Components


Dust Collectors – Dust collector designs are available to handle most dust encountered.  Whether bags, cartridges, pleated bags, blanket media or box filters, maximizing collection efficiency with filter media longevity is the goal.  Understanding of the materials being collected, before equipment selection, will ensure these criteria are met.

Industrial Dampers and Louvers – Industrial dampers may be used to adjust airflow on the clean air side of the pollution control device. Materials of construction will vary depending upon airstream constituents.

Industrial Duct Systems – Industrial duct systems are sized and constructed for the materials being conveyed. Duct, elbows and fitting options include carbon steel, galvanized steel, stainless steel, FRP, and PVC as options.

Flexible Connectors – Duct connected to a fan or blower requires a flex connector for vibration isolation. If noise is an issue, these connectors can be fitted with acoustic treatment to prevent breakout noise from the fan.

Industrial Exhausters – An industrial exhauster conveys the dust or mist with the maximum efficiency while meeting the design performance requirements. Materials of construction vary to match the material conveyed and the airstream chemistry.

Fan Silencers – Fan silencers are selected to attenuate noise from either the fan inlet or discharge, which may or may not be ducted back into the facility. Silencers on the fan inlet prevent noise radiating back thru the collection system into the plant.

Electrical Controls – Electrical Control packages are offered to monitor fan motor speed, dust collector pulse cleaning, and explosion protection devices along with standard start-stop switches and disconnects.

Dust Collector Technologies


They are many air cleaning technologies available for dust and mist filtration. Selection is based on the characteristics of the particulate or mist such as chemistry or abrasiveness, temperature, amount of material collected, explosivity of the materials, amount of maintenance the client can assign to the air cleaner, and location of the air cleaner in the facility. The major dust collector technology options would include:

Cartridge Dust Collectors

Six (6) Donaldson Torit Model DFOs applied to pharmaceutical dusts from weigh scales and tables in formulating rooms.Cartridge dust collectors are the preferred means for dust collection because of their initial efficiency, minimal space envelope and ease of maintenance. That said, baghouses are still required in those process areas where material loadings and material characteristics require their use. When cartridge style units are implemented, Donaldson® Torit® advanced technology cartridge dust collectors and filtration media provide effective solutions for managing a variety of industrial dust control issues including toxic, explosive and potent compounds. Both their Downflo® Evolution (DFE) Collector and Downflo® Oval (DFO) Dust Collector set the standard for cartridge dust collection.
