Abstract
This swirl flow generator is used to purify air by removing foreign matters such as liquid droplets and dusts contained in the air. A cylindrical blade portion (34) is arranged in a swirl flow generating chamber (24) through which the air flows in the axial direction, and the air flowed in the axial direction along the blades (35) is radially jetted toward inside of the cylindrical blade portion (34) to form swirl flow. The air supplied into the swirl flow generating chamber (24) in the axial direction is guided by the closing lid portion (38) toward the inflow-side end surface of the cylindrical blade portion (34). The air flow downward from the outside of the cylindrical blade portion (34) is prevented by the annular base portion (33).
