Cyclone Separation
A method of separating particles from a fluid stream using centrifugal force in a vortex-like pattern.
Cyclone Separation
Cyclone separation is a widely-used industrial process that employs the principles of centrifugal force and vortex dynamics to separate particles from a fluid stream, typically air or liquid, without the use of filters or moving parts.
Operating Principles
The fundamental mechanism relies on creating a spiral fluid flow pattern inside a conical or cylindrical chamber. As the fluid enters tangentially:
- The geometry forces a spiral flow pattern
- Heavier particles experience stronger centrifugal forces
- Particles migrate toward the chamber walls
- Clean fluid exits through the top center
- Separated particles collect at the bottom
Design Components
A typical cyclone separator consists of:
- Tangential inlet
- Cylindrical barrel section
- Conical section
- Dust collection hopper
- Clean fluid outlet (vortex finder)
The design's efficiency depends on careful consideration of fluid mechanics principles and geometric ratios.
