Cyclone dust collector (cyclone) is one of the most favorite equipments which are used for separation of solidparticles from gas. In spite of the extremely simple construction, cyclones have a high centrifugal effect. Therefore cyclones which are combined with another equipments are applied as the measures for dust separation on the air pollution in city planning.
Here the author described the the mechanical characteristics for the performances and the constructions of Tseries cyclone dust collectors which were developed and investigated by CSVZ works in Czechoslovakia. The report of T-series cyclones were based upon a book of “Industrial Separators For Gas Cleaning” by OTAKAR ŠTORCH (Elsevier, 1979). On the strength of the detailed data of T-series cyclones for the constructions, for the fractional collection efficiencies, for the total collection efficiencies, for the driving conditions and for the standard test dusts, the author calculated the Reynold's number Rcy, inerita parameter Φ and the diameters XD1 of the of the mechanical equilibrium particles at the cyclone wall. From those calculated results, total collection efficiencies η c of Tseries cyclones could be settled by the two parameters XC50/XR50 and XD1/XR50, where XC50 was a diameter of cut-size and XR50 was a representative diameter which was corresponding to 50% of the cumulative distribution curves of test dust. And then the coefficient ξ d of pressure drop Δpc could be settled by the inertia parameter φ for T-series cyclones.
T-series cyclones have very fine separation parformances and various kinds of constructions which can be combined as multicyclones. The author believes that those Tseries cyclones are very profitable and suggestive for considering cyclone dust collectors in our country.
