Baghouse and Bagfilter
Air Pollution Control
Fabric dust collectors are commonly known as bagfilters and Baghouses are the most efficient and cost effective dust collector models. Dust enters the fabric filter compartment. Larger particles drop out while smaller dust particles collect on filter Bags. When the dust layer thickness reaches a level where flow through the system is restricted (called pressure drop or delta P), the bag cleaning process is initiated. Cleaning can be done while the compartment is still online (filtering) or in isolation (offline). Once cleaned, the compartment is placed back in service and the filtering process starts over. There are three prominent types of cleaning process in bagfilters and baghouses: Reverse Air (Gas Cleaning), Pulse Air (Compressed Air Cleaning) and Shaker (Mechanical Cleaning). Bags are made of different material such as woven or felted cotton, synthetic, or glass-fiber.
