Baghouses are used in many different applications to remove particulate matter from air and gas streams. They typically have very high removal efficiencies, often over 99%. The fabric bags used in baghouses must be cleaned intermittently to remove the dust cake that builds up. This course discusses the cleaning mechanisms used in the three main baghouse designs – shaker, reverse air, and pulse jet. It also covers the different fabrics that can be used, filter canisters with pleated filter media, and sonic cleaning horns. When selecting or designing a baghouse, you must know several characteristics of the air or gas stream and the particles it contains. This course lists the critical design variables and also the calculations used to select an appropriate baghouse design and size it properly.
