Dust collection involves the capture of air contaminated by dust in order to filter the air by removing the dust matter and release the remaining clean air and gas back into the environment. Dust collection services involve a continuous process for dust collecting of any process-generated dust particles from the source point. Dust collection is used to recover valuable material, as in silo vents, or to remove granular solid pollutants from exhaust gases before venting them back into the atmosphere. In many cases, dust collection is used in conjunction with air pollution control equipment to improve air quality.
Dust collection is done by dust collectors, which are designed to collect dust as classified by size in three categories: respirable dust collectors, inhalable dust collectors, and total dust collectors. Respirable dust collectors help remove dust that is able to penetrate deep into the lungs, while inhalable dust collectors remove dust that is trapped in the nose, throat and upper respiratory tract. Total dust collectors collect both types of dust. Some popular methods of dust collection include cyclone separator dust collection, cartridge dust collection, electrostatic precipitator dust collection, fabric dust collection (also known as baghousing), unit dust collection, vibrator dust collection, and wet scrubber dust collection.
Since dust can remain in the air for an indefinite period of time without any chemical change other than fracturing, dust collection is necessary in order to remove the presence of excessive dust. This dust can be dangerous and cause such hazards as respiratory diseases, irritation to eyes, ears, nose, throat and skin, dust explosions or fire, and damage to manufacturing equipment.
