| Abstract: | According to an analysis of the compound electro-cyclone's dust collection principle,it is opined that centrifugal operation,electro-static precipitation,electric field restraining effect and agglutination simultaneously play a certain role within a limited space.All active factors that appear during the dust collection process are related either with Stokes' forces,centrifugal forces or electrostatic forces,and all of them depend on the separator's structure and the electrodes' positions.A method of calculating,accompanied by relevant formulae,tangentially entering,back cycling electro-cyclones is being presented.Various design calculation results compared with actual test data show that the presented method has a practical significance.Figs 7,table 1 and refs 15. |
