Research Findings Concerning the Effect of Axle Shapes on the Performance of Cyclone Separators

The authors have studied a kind of high-concentration salt-mist separating device-cyclone separator,and numerically simulated under rated operating conditions three models of cyclone separators featuring three axle shapes,namely,1.hollow cylinder shape,2.slim solid truncated cone shape and 3.podgy solid circular truncated cone shape.The drag force characteristics of the corresponding models and their separation-efficiency characteristics at different particle diameters have been given.Meanwhile,on a specialized wind tunnel test rig,drag force and separating efficiency characteristics of the three models were also tested.The test results show that model No.2 has a relatively stable separating efficiency and a comparatively small drag-force loss with its overall performance being better than that of the other two models.When comparing the test results with the numerical simulation ones,one can find that they are in good agreement,thus providing reference data for further investigations.
