A family of optimised cyclones has been surprisingly detected, when incorporating into cyclone calculation the interparticle agglomeration phenomenon, the main cause of the capture of submicrometric particles by greater particles preferably having diameters of 10-20 µm, the family of optimised cyclones having a geometry defined by the following non-dimensional parameters: a/D 0.110-0.170; b/D 0.110-0.170; s/D 0.500-0.540; D e /D 0.100-0.170; h/D 2.200-2.700; H/D 3.900-4.300; D b /D 0.140-0.180, wherein a and b are the sides of the tangential cyclone entrance, which has a rectangular cross-section, and the first of these sides is parallel to the axis of the cyclone, which has a body of height H with a cylindrical upper section having an inner diameter D and a height h, and a lower section with an inverted truncated cone shape with a minor base having the diameter D b ; and a cylindrical vortex tube of height s and diameter De (inner dimensions). Global efficiency is maximised in that the efficiency for finer and/or less dense particles, which are the most difficult to capture, is maximised. |
