Pussisiivilät

Pussisiivilät, often translated as bag filters or baghouses, are industrial pollution control devices used to remove particulate matter from exhaust flue gases. They are a type of mechanical filter that employs a series of fabric bags to trap dust and other fine particles. The dirty gas stream enters the filter housing, where it passes through the bags. The dust particles are collected on the outer surface of the bags, forming a dust cake. The clean gas then exits the baghouse.

The collected dust cake can be removed from the bags through various cleaning mechanisms, such as shaking, reverse air, or pulse-jet cleaning. These methods dislodge the dust cake, which then falls into a hopper at the bottom of the baghouse for disposal or further processing. Pussisiivilät are highly effective at capturing even very fine particles, making them suitable for a wide range of industrial applications, including power plants, cement factories, and chemical processing facilities. The choice of fabric material for the bags depends on the temperature and chemical composition of the gas stream. Regular maintenance and inspection are crucial to ensure the efficient operation and longevity of a pussisiivilä.
