18 Best Industrial Dust Collection Types

Industrial facilities require effective industrial dust collection systems to control particulate matter and fumes generated during manufacturing. Proper air pollution control equipment like cyclones, wet scrubbers, baghouse filters, and electrostatic precipitators remove potentially harmful dust and fine particles from the air. This improves workplace safety and air quality in the surrounding environment. Companies like Ducon Environmental offer customizable dust collection solutions including High-Efficiency Cyclones, Venturi Scrubbers, Dry ESPs, Activated Carbon Systems, and more. Their products provide continuous operation while ensuring environmental compliance.

II. Types of Industrial Dust Collection Systems

There are various technologies available for industrial dust collection:

Baghouse Filters

  • Fabric filter baghouses are one of the most common and efficient options, achieving up to 99% collection efficiency. The system draws dust-laden air through a series of fabric filter bags that capture particulates. Filter bags periodically undergo pulse jet cleaning to remove accumulated dust cake. Ducon Environmental offers high quality baghouse filters for heavy duty applications.

Cyclone Dust Collectors

  • FCC Cyclones created by Ducon are a type of inertial separator that uses circular airflow to push dust particles against the cyclone wall. The collected dust slides down to a hopper at the bottom. FCC cyclones effectively remove large and heavy particles.
  • High-Efficiency Cyclones, another Ducon product, achieve a high collection efficiency up to 99% for fine particulates. They can serve as pre-cleaners to protect downstream equipment.

Wet Scrubbers

  • Venturi scrubbers inject water into dust-filled air to capture particles. Ducon provides venturi scrubbers for particulate removal.
  • Packed tower scrubbers from Ducon use structured high surface area packing material to remove pollutants.

Electrostatic Precipitators

  • Ducon’s Dry ESPs electrically charge dust particles to collect them on oppositely charged plates.

B. Cyclone Industrial Dust Collectors


Cyclone dust collectors use circular airflow within a conical chamber to separate dust particles from exhaust air. Ducon Environmental provides the following cyclone technologies:

i. FCC Cyclones

  • FCC cyclones are inertial separators designed for high efficiency removal of coarse particulates.
  • They create a vortex that pushes particles outward to the cyclone wall by centrifugal force.
  • Collected dust slides down the wall into a hopper for disposal.
  • FCC cyclones can handle heavy dust loads and abrasive particles.
  • They are often used as pre-cleaners to protect downstream baghouse filters and other equipment.
  • Industries served include cement, steel, mining, power generation, and more.

ii. High-Efficiency Cyclones

  • Ducon’s high-efficiency cyclones achieve fine particulate collection efficiency up to 99%.
  • They utilize advanced internal aerodynamics for superior dust removal.
  • The cyclones can operate under high temperature and pressure conditions.
  • Applications include fume extraction, light dust collection, and industrial ventilation.
  • They are constructed of carbon steel or stainless steel to withstand harsh environments.
  • High-efficiency cyclones can also be used as pre-cleaners prior to wet scrubbers or other systems.
  • Compared to baghouses, they have lower maintenance requirements for continuous operation.

Ducon’s cyclone products provide customizable, heavy-duty dust collection solutions for demanding industrial processes.

C. Wet Scrubbers

Wet scrubbers from Ducon Environmental remove dust, fumes, and other pollutants by contacting the gas stream with a liquid. They provide high efficiency collection for fine particulates.

i. Venturi Scrubbers

  • Venturi scrubbers inject water into the gas stream through a converging-diverging venturi nozzle.
  • The liquid atomizes and entrains particles as it collides with the dust-filled air.
  • The venturi throat creates accelerated airflow that improves particle capture.
  • Ducon provides venturi scrubbers for various industrial processes.
  • They effectively remove fine dusts below 3 microns.
  • Applications include nuisance dust control, industrial ventilation, and visible plume abatement.
  • Venturi scrubbers can handle heavy dust loads without plugging.
  • They require relatively low maintenance compared to other wet scrubbers.

ii. Packed Tower Scrubbers

  • Packed tower scrubbers from Ducon utilize structured high surface area packing material to remove pollutants.
  • Gas flows through packed beds while liquid flows countercurrently.
  • The liquid absorbent captures contaminants like acids, soluble gases, and particulate matter.
  • Ducon’s packed towers come in fiberglass or stainless steel construction.
  • They are used for gas scrubbing applications including SO2 absorption, VOC removal, and more.
  • Packed tower scrubbers provide high collection efficiency in a compact footprint.

Ducon’s wet scrubber products offer customizable solutions for demanding dust collection needs.

D. Electrostatic Precipitators

Electrostatic precipitators use electrostatic forces to remove dust particles from exhaust gases. Ducon provides the following ESP technology:

i. Dry ESPs

  • Dry ESPs from Ducon utilize electrostatic attraction to collect dust.
  • Particles passing between vertical wire discharge electrodes and flat collection plates become positively charged.
  • The charged particles migrate to the grounded plates and are removed.
  • Ducon offers both conventional and rigid frame dry ESP designs.
  • Their ESPs achieve high collection efficiency up to 99% on submicron particulates.
  • Applications include dust collection from industrial boilers, furnaces, kilns, and other processes.
  • Dry ESPs can operate under high temperature conditions up to 750°F.
  • They can handle heavy dust loads including abrasive particulates.
  • Periodic rapping of plates dislodges accumulated dust cake for removal.

  • Industries served include power generation, cement, steel, chemical, and more.

Ducon’s Dry ESP technology provides a customizable and reliable solution for demanding industrial dust collection applications. The high efficiency and low maintenance requirements make them advantageous for continuous operation.

E. Activated Carbon Systems

In addition to particulate collection, Ducon Environmental provides gas phase filtration solutions including activated carbon systems:

  • Activated carbon adsorption is used to remove harmful VOC, odor, and gas phase contaminants.
