What is the primary function of cyclones in air pollution control?

The primary function of cyclones in air pollution control is to remove large particles from the airstream. Cyclones operate on the principle of centripetal force; as the air enters the cyclone, it is spun around in a circular motion. This motion creates a centrifugal force that pushes heavier particles toward the walls of the cyclone, where they are collected. As a result, larger particulates, such as dust and ash, can be effectively separated from the air, reducing overall pollution levels.

While cyclones are efficient at removing larger particles, they are not as effective at capturing smaller particulates or filtering gases. Smaller particles may remain suspended in the air and pass through the cyclone, and gases typically require different treatment technologies for effective removal. Additionally, cyclones do not disperse pollutants; rather, they concentrate and remove them from the airstream, making them more suitable for managing particulate pollution specifically.
