Abstract
Air pollution control devices vary in terms of the principle of their work and the factors affecting the efficiency of their performance. Some of them work according to the principle of gravity, such as the settling chamber, which works according to the effect of centrifugal force such as Cyclone, and others work according to the principle of filter cloth and insulation. The dust from the fabric fibers to form a cake layer acts as an additional filter, such as bag filters, and the electrostatic precipitators act according to the principle of ionization in the corona (electrical discharges produced when a high voltage passes through a conductor wire passing through a medium) (Gaseous at atmospheric pressure) and thus the formation of ions, (The Cull Code), the dust particles are separated and collected because of the charge they carry, as well as wet scrubber systems that operate in a fluid manner Water or other liquids, for the purpose of capturing dust particles or gas molecules.
