An original design of a separating device with arc-shaped settlers (SDAS) has been developed to purify air from solid particles. In this study, the separation efficiency of the device was studied numerically. The influence of the number of rows of arc-shaped settlers of the SDAS on its efficiency was evaluated. Geometric models of the separating device with three configurations were used: 5, 7, and 9 rows of arc-shaped settlers. The diameter and height of the arc-shaped settlers and the distance between the rows were the same for all models. The results obtained showed that the most effective configuration of the separating device that allows the maximum efficiency of particle removal from a dusty gas stream was observed with 5 rows of arc-shaped settlers, providing an efficiency of about 66.7% with an input gas stream rate in the range of 0.5 to 3 m/s. It was found that the separation efficiency decreases with an increasing number of rows and stream rate of the gas stream as a result of particle reflection from the device walls.
