Home / Applications / Filtration Solutions / Cyclones
Cyclones are very common particulate control devices used in many applications, especially those where relatively large particles need to be collected. Cyclones are very simple devices that use centrifugal force to separate particles from a gas stream. With a low capital cost, small space requirement, and no moving parts, Cyclones are able to handle very heavy dust loading, and they can be used in high-temperature gas streams.
A typical Cyclone has a tangential inlet to a cylindrical body, causing the gas stream to be swirled around. As the gas loses energy in the swirling Vortex, it starts spinning inside the Vortex and exits at the top. The Vortex Finder Tube does not create the Vortex or the swirling flow. Its function is to prevent short-circuiting from the inlet directly to the outlet.
These cyclones are high-efficiency separators with an optimized high degree of separation and low head loss. They have proven themselves for many centuries in numerous industrial cases of operation. Depending on the application and kind of dust, they are used as exclusive de-dusting or as a pre-separator.
A big selection of different sizes is available; designed as a mono cyclone, for volumes between 560 m³/h and 113,000 m³/h. For reasons of transport or for the use for still higher volumes, the cyclones can also be designed as twin or quadruplet separators.
Saveeco Energy cyclone filters are characterized by a high filtration efficiency and low-pressure loss. The cyclones can be added with a special feature designed for protection against explosion.
Cyclones
Cyclones are very common particulate control devices used in many applications, especially those where relatively large particles need to be collected. Cyclones are very simple devices that use centrifugal force to separate particles from a gas stream. With a low capital cost, small space requirement, and no moving parts, Cyclones are able to handle very heavy dust loading, and they can be used in high-temperature gas streams.
A typical Cyclone has a tangential inlet to a cylindrical body, causing the gas stream to be swirled around. Particles are thrown toward the wall of the Cyclone’s body. As the particles reach the stagnant boundary layer at the wall, they leave the flowing gas stream and presumably slide down the wall, although some particles may be re-entrained as they bounce off of the wall back into the gas stream. As the gas loses energy in the swirling Vortex, it starts spinning inside the Vortex and exits at the top. The Vortex Finder Tube does not create the Vortex or the swirling flow. Its function is to prevent short-circuiting from the inlet directly to the outlet. Cyclones will work without a Vortex Finder, although the efficiency will be reduced.
