Using Nanotechnology for More Efficient Dust Collection
|
From United Air Specialists, Inc.
Nanotechnology — the control of matter smaller than 1 micron — is a hot topic. Nanotechnology is used in products as diverse as atomically engineered food, anti-aging cosmetics, stain-resistant clothing, self-cleaning window glass, high-performance golf clubs, and information storage products. But for companies that process and handle dry bulk solids, one of the most exciting and useful applications of nanotechnology is the use of nanofiber media in dust collector cartridge filters. When used in these filters, one microscopic layer of fibers 1,000 times smaller than the diameter of a human hair can translate into huge advantages in filter efficiency, cleanability, filter life, and energy use.
A typical dust collector cartridge filter is a cylinder of pleated fabric (called media) on a cylindrical frame. The filter has two endcaps, and one is attached to the dust collector’s tube sheet, a frame that holds one or several cartridge filters. Dust-laden (dirty) air enters the dust collector and passes through the cartridge filter’s media, leaving most of the dust on the filter’s exterior (dirty side) and embedded within the media, while clean air passes to the cartridge’s interior (clean side). The clean air is exhausted to the atmosphere or back to the process. The dust from the dirty
Products & Services
Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere.
Mist collectors and fume collectors reduce the amount of mist, aerosols and fumes in the workplace atmosphere.
Industrial vacuums are capable of picking up large quantities of material and/or liquids. They can be portable devices or part of a central vacuum system.
Industrial air filters reduce the number of particles in the air that passes through them.
Air scrubbers, wet scrubbers, and gas scrubbers are air pollution control devices that use a high-energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction.
