Types of Dust Collectors and How They Work

Dust collection equipment is responsible for capturing and filtering the particles released during manufacturing processes which are hazardous to both worker and equipment health. Dust collectors draw contaminated air through a filter or separator, trapping harmful particles and releasing cleaner air into the atmosphere or back onto the work floor. Industrial dust collectors come in various types and sizes, including fabric filter baghouses and jet dust collectors, cyclone dust collectors, wet dust collectors, cartridge collectors and downdraft tables.

When it comes to dust collection and dust collectors, there are five main types of such equipment. These include inertial separators, fabric filters, wet scrubbers, electrostatic precipitators, and unit collectors. The variances among these types may determine their suitability for specific industries and applications. Below is a brief introduction to each of these pieces of equipment and how they work.

Inertial Separators: Inertial separators work by employing a combination of forces including gravitational, centrifugal, and inertial. These forces separate the dust from the gas streams that enter it. Gravity then works to move the dust into a hopper for temporary storage. Inertial separators can be broken down into types as well, and these include settling chambers, baffle chambers, and centrifugal collectors. Settling chambers and baffle chambers are often used in pre-cleaning applications and centrifugal collectors (of which there are also many types) are used in a wide variety of industrial applications from metallurgical plants to saw mills and pulp and paper plants.

Fabric Filters: Often known as baghouses, fabric filters are very efficient as well as cost effective. Dusty gases pass through fabric bags of various materials such as felted or woven cotton and glass-fiber material. Fabric filters are relied on heavily as they have collection efficiency of over 99% for very fine particles.

Wet Scrubbers: Wet scrubbers use liquid (usually water) for another method efficient dust removal. Again a gas stream containing dust comes into contact with liquid streams, which carry the dust away leaving purer gases. Types of these wet scrubbers are based on energy uses such as low-energy scrubbers up to high-energy scrubbers.

Electrostatic Precipitators: Electrostatic precipitators use (you guessed it) electrostatic forces to remove dust from gases. With these, particles become negatively charged as they pass through a field between direct-current, high-voltage discharge electrode. These particles are thus attracted to positive charged electrodes and adhere to them to later be removed continuous vibration or rapping.

Unit Collectors: Unit collectors are employed at the source where dust is created and utilize fans along with other dust collection materials like fabric. These are usually low in cost and portable and ideal for small operations or facilities with limited space.

Though these types of dust collectors work employing different materials and methods, each is about as efficient as the next, but one might work better in your space and for your operations. Contact a provider near you for more detailed information about a system that would work best for you.

Dust Collectors

The particles released during manufacturing processes are hazardous to both worker and equipment health, quickly leading to a number of problems if particles are not captured by dust collection equipment and filtered from facility air. Dust collection addresses this problem by drawing contaminated air through a filter or separator, trapping harmful particles and releasing cleaner air into the atmosphere or back onto the work floor. Industrial dust collectors come in various types and sizes, including fabric filter baghouses and jet dust collectors, cyclone dust collectors, wet dust collectors, cartridge collectors, small dust collectors, portable dust collectors, downdraft tables and dust collecting systems complete with multiple suction hoods and overhanging ductwork. Dust collection is a vital process for coal handling, cement fabrication, metal fabrication, mining, chemical processing, woodworking, pharmaceutical, recycling and agricultural industries, among many others. Industry-specific state OSHA regulations require companies to hold their facilities to strict standards for indoor air quality, and the EPA and other regulatory bodies put limits on emissions of dust, smoke and fumes into the atmosphere. Dust collectors play a major role in helping companies meet these requirements and improve both indoor and outdoor environments by capturing a high percentage of the particles emitted by industrial processes.

Baghouses are the most common dust collector design and are often the most cost-effective. Baghouses draw contaminated air in through ducts to a hopper-shaped baghouse containing fabric filters made of cotton, synthetics or glass-fiber. The air is pulled through the fabric bags by a vacuum-creating fan, leaving behind dust, smoke and particles; clean air exits through the fan at the outlet, while dust particles either cling to the filter or settle into an airlock at the bottom of the hopper, which is routinely emptied. As a cake of dust accumulates on the filter, it actually increases the effectiveness of the filter for trapping tiny particles. After a point, however, the filter cake can become too thick and begins to stress the system, so occasional cleaning is necessary to ensure sufficient airflow through the filters. For this reason, baghouse dust collectors are sometimes equipped with vibrators that shake filters free of dust. Similarly, jet dust collectors are baghouses which use jets of compressed air to blow the dust-caked fabric bag filters free of excess dirt.

Some dust collectors, such as cyclone dust collectors, settling chambers and baffle chambers, do not rely on filters but instead rely primarily on gravity and inertia, and thus are known as inertial separators. Cyclone dust collectors use centrifugal, or cyclonic, air movement within a hopper-shaped chamber to separate particles from the air; the particles, being heavier than air molecules, are thrown against the outer wall of the hopper and fall to the bottom, where they are collected. Multi-cyclone dust collectors have a single main inlet on one side and a single outlet on the other side, but incorporate many cyclone cylinders inside the chamber that run concurrently; single-cyclone dust collectors have only one cyclone. Settling chambers reduce the speed of an air stream, which allows the heavier particles to settle out more quickly. Baffle chambers set up a barrier that forces the air to change directions suddenly, so that the inertia of the heavier particles does not allow them to remain suspended in the air stream and they fall to the bottom of the chamber. Cyclone dust collectors, settling chambers and baffle chambers are most effective at removing the coarser dust particles from contaminated air, and so are well suited as pre-cleaners for baghouses and other dust collectors that are more efficient at removing fine particulate.

Large facilities usually incorporate baghouses, jet dust collectors and inertial separators into sizeable dust collecting systems, with overhead ductwork and capture arms with suction hoods that hang over the workspaces where dust is formed. In such applications, the dust collector apparatus is often located outside of the facility, connected to the interior by ducts. Facilities may also use smaller, self-contained ‘unit' dust collectors or portable dust collectors, either in addition to or in place of larger systems. Generally using fabric filters or cyclonic motion to collect particles, portable dust collectors can be easily moved from place to place to provide localized dust collection. Similarly, downdraft tables are work tables with built-in dust collection equipment for filtering the dust from processes performed over the table, such as welding and wood sawing. Some special downdraft tables and unit dust collectors, known as wet scrubbers or wet dust collectors, use liquids (usually water) to intercept dust particles from the stream of gas. Others, known as electrostatic precipitators, give particles a negative charge and then attract them out of the air stream by means of a positively charged electrode. Wet scrubber and electrostatic precipitator technology is also employed in some air pollution control equipment, performing similar functions on molecular levels by removing soot, smog and fine chemical pollution from the air of industrial facilities. As the dust collecting industry advances, smaller, cleaner and more efficient separating and filtering equipment is being developed to better meet the needs of industry while increasing worker safety and protecting environmental health.

Dust Collector Types

  • Baffle chambers cause dusty air to change direction suddenly so that gravity and inertia carry the heavier dust particles downward, out of the air stream and into a collection area.
  • Baghouses are dust collection filters typically constructed from glass fibers or fabric.
  • Cartridge Collectors are compact filters that have a much greater surface area than bags, which increases the airflow, lowers resistance and reduces frequency of cleaning.
  • Cyclone dust collectors rely on centrifugal force to remove dust from air.
  • Cyclone separators filter dust particles by spinning the air around in its tank. The motion pins the particles against the walls; they gradually move downward and eventually end up in the collection bin.
  • Downdraft booths are systems that vent from the top and pull fumes and dust up past the worker's face.
  • Downdraft tables or workstations have perforated tabletops and back walls and draw dust and fumes away from the worker's breathing zone.
  • Dust collecting systems filter air and remove dust before releasing clean air back into the environment.
  • Dust collection is the process of filtering air and removing dust.
  • Dust collection equipment encompasses a wide variety of devices and systems designed to minimize air particle contamination in commercial and industrial spaces.
  • Electrostatic precipitators collect dust through ionization. As dust-filled gases move through the system's positively-charged, grounded electrodes called collection plates, discharge electrodes give the dust particles a negative charge, which causes the ionized dust particles to be attracted to and caught by the collection plates.
  • Fabric collectors, or baghouses, contain filters called fabric bags, which efficiently trap fine particles of dust, while allowing gases to move through the collector.
  • Industrial dust collectors minimize the presence of various pollutants in order to maintain a high standard of clean air in workshops, plants and manufacturing facilities.
  • Inertial separators separate dust particles from gas by changing the direction of gas streams as the streams flow through the collector.
  • Jet dust collectors use a jet-based cleaning cycle.
  • Portable dust collectors can be moved from place to place.
  • Pulse jets use compressed air to force a burst of air down through the fabric bag and expand it violently. When the bag reaches its limit, the dust separates from the bag, and the escaping air carries the dust away from the fabric surface.
  • Settling chambers slow the movement of dusty air to allow for the heavier particles to settle out.
  • Silo vents collect the product in filter bags as the silo is being filled with material. The bags are then shaken to return the valuable product to the silo.
  • Small Dust Collectors solve air pollution problems when limited space for filtration is available.
  • Unit collectors are small dust collecting systems that contain a fan and either a fabric collector or a cyclone.
  • Ventilators pull a continuous stream of air from the environment, removing airborne dust particles.
  • Wet dust collectors soak dust-filled gas streams with water and separate the wet dust particles through varying degrees of pressure drops.
