Study of the structure of gas flow іn a cyclone wіth іntermedіate dust removal

The works in which designs of the dust collectors, are often used industry, analyzed. It is shown that efficiency collectors largely depends on structure gas flow apparatus. Based analysis current cyclone devices, a picture separation process obtained, and factors negatively affect operation identified. established forecasting work collecting devices certain conditions most effective to perform methods numerical modeling simulation process, widely for research this type. Using simulation, study with intermediate removal was carried out. In cyclone, change radius apparatus tangential, radial, axial velocity components investigated. course research, it space tangential component increases from 18–20 m/s upper part device 22–25 area lower end exhaust pipe, radial takes values 0 2 m/s, speed has maximum value 10–15 m/s. conical decreases 27 planes 10 m / s near unloading centripetal character, as pipe decreases. been cylindrical about 60 % volume transferred downstream upstream by secondary vortex, part, 40 upstream. large zone contribute ingress particles into annular behind holes, small velocity, holes positive effect collector.
