A bag filter is an industrial air pollution control device used in steam boiler houses to reduce
pollutants like sulfur dioxide in the air. Bag filters are effective at filtering flue gases by
separating and collecting particles at the bottom. The flue gas then passes through the outlet,
while the hazardous particles are disposed of. This helps to improve air quality and reduce the
risk
of respiratory problems and other health effects associated with exposure. Bag filters can also
help
to protect boiler components from damage.
Bag filters can be made of woven or felted cotton, synthetic or glass fiber, and come in either
a
tube or envelope shape. There are many different types of bag filters, including Shakers,
Reverse
Air, and Pulse Jet types. The Pulse Jet type is considered the most promising type and consists
of a
four-sided hollow metallic body that is conical at the downside. It also has a vertical squirrel
cage type arrangement for supporting and holding the filter bags.
