Säkkisuodattimia

Säkkisuodattimia, known in English as bag filters or baghouses, are industrial air pollution control devices that use bags of fabric to filter dust and particulate matter from exhaust gases. They are a common and effective method for removing solid particles from industrial emissions. The process involves drawing contaminated air through a series of fabric bags, which capture the dust particles. The clean air then exits the system, while the collected dust accumulates within the bags.

The collected dust can be removed from the bags through various methods, such as mechanical shaking, reverse air flow, or by using a pulse-jet system that blasts compressed air against the bags to dislodge the dust. The dislodged dust then falls into a hopper at the bottom of the baghouse, where it can be collected and disposed of or potentially reused. The choice of fabric for the bags depends on the temperature and chemical composition of the gas stream. Common materials include polyester, polypropylene, and fiberglass.

Baghouses are widely used in industries such as cement manufacturing, power generation, steel production, and food processing, where high volumes of particulate matter are generated. Their efficiency in capturing fine particles makes them an important tool for environmental protection and workplace safety. Regular maintenance, including inspection and replacement of worn bags, is crucial for ensuring the continued effectiveness of a säkkisuodatin system.
