FIELD: power engineering, in particular, purification of gases. SUBSTANCE: cyclone has casing 1 with conical nozzle 2 and cover 3, distributing chamber 4, inlet chamber 5, discharge pipe 6, swirling device with lower, middle, upper disks 8,9,10 defining two tiers with convex blades 11,12 of upper and lower tiers, respectively. Number of blades of upper tier exceeds that of lower tier. Inner diameter of middle disk 9 exceeds inner diameter of lower and upper disks 8,10. Middle disk 9 and casing 1 define slit 13. Chamber 14 is defined by casing 1, cover 3 and disk 10. Chamber 14 has branch pipe 15 with regulator 16, shield 17 attached to disk 9 to define with casing 1 chamber 18 and with disk 8 - slit 19. Cyclone has guiding devices 20,22 with convex blades oriented in opposite directions relative to blades 11,12. EFFECT: increased efficiency in purification of dust-laden gases and enhanced reliability in operation. 5 cl |
