|
| |
Metalworking Chips / Fluids
|
|
Collecting metal scraps poses a potential health hazard to fabricated metal workers due to the oils, lubricants, and coolants that must be collected with the metal. Once picked up by an industrial vacuum cleaner, these metalworking fluids (MWFs) emit harmful aerosols that may contaminate the working environment, damage nearby equipment, and make floors slippery.

|
The unit is designed to reclaim, recycle, or recover materials for reuse.
|
| |

Systems for fine removal may only contain a single filtration system (such as a filter bag or cartridge). However, most units utilize a primary and secondary separation / filtration system. Furthermore, some units may have third and fourth stage filtration. All separation and filtration systems used within the unit should be specified.

Bag-type Units (Baghouse)
|
|
A baghouse is an air pollution abatement device used to trap particulate by filtering gas streams through large fabric bags typically made of glass fibers or fabric.
|
| |
Cartridge-type Units
|
|
Filter cartridges are made out of a variety of synthetic fibers and are capable of collecting sub-micronic particles without creating an excessive pressure drop in the system. Filter cartridges require periodic cleaning.
|
| |
Cyclone (Centrifugal) Separators
|
|
A cyclone separator is an apparatus for the separation, by centrifugal means, of fine particles suspended in air or gas.
|
| |
Electrostatic Precipitators
|
|
Electrostatic precipitators are a type of air cleaner, which charges particles of dust by passing dust-laden air through a strong (50-100 kV) electrostatic field. This causes the particles to be attracted to oppositely charged plates so that they can be removed from the airstream.
|
| |
Impinger System
|
|
A device in which particles are removed by impacting the aerosol particles into a liquid.
|
| |
Modular Media Type
|
|
Modular media type units combine a variety of specific filter modules in one unit. These systems can provide solutions to many air contaminant problems. A typical system incorporates a series of disposable or cleanable pre-filters, a disposable vee-bag or cartridge filter. HEPA or carbon final filter modules can also be added. Various models are available, including free-hanging or ducted installations, vertical or horizontal mounting, and fixed or portable configurations.
|
| |
Venturi
|
|
A wet scrubber, or Venturi scrubber, is similar to a cyclone but it has an orifice unit that sprays water into the vortex in the cyclone section, collecting all of the dust in a slurry system. The water media can be recirculated and reused to continue to filter the air. Eventually the solids must be removed from the water stream and disposed of.
|
| |
Wet Spray
|
|
Achieves intimate mixing by passing the contaminated gas through a constriction partly submerged in scrubbing liquor. This creates a spray in which particulate material is scrubbed.
|
| |
Packed Bed / Column
|
|
A common type of gas absorber in which scrubbing liquid is dispersed over packed columns containing packing material. This design provides a large surface area for gas-liquid contact.
|
| |
Dry Injection
|
|
An air pollution control system that injects a dry sorbent into an exhaust stream.
|
| |
Dry Spray
|
|
An air pollution control device for removing acid gases where an alkaline slurry is introduced into the gas stream and the pollutants absorb into the droplets and react. The droplets dry in the gas stream leaving particulate matter, which is collected by a downstream particulate control device.
|
| |
Circulating Fluid Bed
|
|
A fluidized bed system that has high air velocities (as high as 30 feet per second) and fine particle sizes. As a result, the fluid bed is less dense (35 pounds per cubic foot) and has no well-defined top surface. Large quantities of bed material are recaptured from the gas stream and recirculated back to the furnace to maintain bed inventory.

|
Automatic (continuous or timed) shaking action provides a back and forth motion. The shaking action aids separation by spreading the material around the filter and/or bouncing the material.
|
| |
Manual Shaking
|
|
Manual shaking action provides a back and forth motion. The shaking action aids separation by spreading the material around the filter and/or bouncing the material.
|
| |
Pulse-jet
|
|
Blasts of air used to dislodge particles and clean the filter.
|
| |
Reverse Air
|
|
In the reverse-air technique, air is blown back through the filter material to remove dust. The compartment must be periodically shut down for the cleaning technique to effectively remove the material from the surface of the fabric filters.
