CYCLONE-SEPARATOR Russian patent published in 2004 - IPC

FIELD: chemical; food; building; pharmaceutical; metallurgical and other industries. SUBSTANCE: the invention is intended for dry cleaning of gases from a dust and may be used in chemical, food, building, pharmaceutical, metallurgical and other industries, as well as in ecological processes of clearing of flue gases and ventilation emission. In the cyclone separator, that contains a cylindrical body with a cone-shaped bottom, a tangentially located connecting pipe for introduction of a dusty gas stream in the apparatus and a connecting pipe for the dust removal, an exhaust pipe. The cylindrical body with the cone-shaped bottom beginning from the inlet branch-pipe is placed coaxially in a cylindrical body with cone-shaped bottom of the bigger diameter forming a clearance between them, and on the cylindrical body of the smaller diameter there are longitudinal slots. The new thing of the invention is, that: 1) the longitudinal slots of a constant or variable breadth are ended at the lower base of the internal cone-shaped bottom and are inclined lines in relation to a vertical with a critical angle α defined from the following relationship: α, = tgα = π. D/H, where D - a diameter of the internal cylindrical body, = - the height of the internal cylindrical body; 2) or the surface of the internal cylindrical body with the cone-shaped bottom has a perforation by apertures made in the form of a trapezium, the first smaller basis of which is equal to the smallest diameter of separated particles, the second basis of the trapezoid on the dusty air run course is equal to the greatest diameter of the separated particles, and the height of the trapezoidal apertures is perpendicular or inclined in respect to the vertical on the side surface of the perforated cylindrical body with a critical angle tgα = π. and, defined from the relationship: α, = tgα = π D/H, where D - a diameter of the internal cylindrical body, = - the height of the internal cylindrical body. Technical result is increase of the cyclone separator overall performance effectiveness, expressed in increase of its productivity and dusty gas separation efficiency. EFFECT: increased the cyclone separator productivity and dusty gas separation efficiency. 2 cl, 6 dwg
