Cyclone dust separators configuration

Obermair and Staudinger (2001) studied the gas flow, pressure drop and separation efficiency in cyclones with the dust outlet configurations shown in Fig. 15.1.9. The corresponding performance data is presented in Table 15.1.2. Upon comparison, we see that configuration a is not as efficient a design as the others. This is probably due to re-entrainment from the solids hopper. It does exhibit a comparatively low pressure drop, however. Its two vortex-stabilized... 

The constructive-technological intensification of processes of clearing of gases is connected with perfection of a configuration of constructive elements of dust removal apparatuses (Ivanov, 1998 and Kuznetsov, 1989). For example, at cyclone separators improve cases, upstream ends, the overhead covers, exhaust tubes,and sp pm. 

Careful design of the dust outlet section of the cyclone can mean the difference between a cyclone working satisfactorily and one emitting coarse particles reentrained into the vortex from the material already separated. Figure 15.1.9 shows four possible configurations of the dust outlet.
