REDUCING ENERGY LOSS IN CYCLONES
The article presents the short literary review of existing ways of decrease energy consumption of cyclones and also gives conditional classification of these ways. The basic designs blade deswirlers and untwisting devices, established on an exit from a cyclone are described. Examples of updating of an exhaust pipe for decrease cyclone pressure drop are shown. The basic advantages and demerits of the resulted designs are analyzed. Installation of the untwisting device allows to lower energy losses in a cyclone by as much as 20% without change of factor of clearing. Pressure drop across the cyclone can be lowered on 50% and above, however efficiency of gas treating thus decreases, that, as a rule, is inadmissible in the industry.
