DEVICE FOR SEPARATION OF SOLID PARTICLES FROM GAS FLOW Russian patent published in 1999 - IPC

FIELD: dedusting of gases; may be used in size classification of polydispersed materials. SUBSTANCE: device has member for setting up of field of centrifugal forces acting on solid particles. The member is made in the form of bent part of gas duct forming one turn and located in one plane. Outlets for discharge of separated solid particles are located over the length of bent part of gas duct on outer surface with maximum radius of bent. Internal part with smaller bend radius of duct has projections. EFFECT: easily accessible for repairs, provided with system for self-compensation of heat and mechanical stresses; higher capacity and efficiency. 6 cl, 1 dwg
