Try to add some more portion of cyclone main body into inlet to avoid sharp edge.

Thank you for your response
In your opinion I must change in geometry? (If I understand truly) This change may effect on fluid flow patterns. Am I right? |

yes, as bharath mentioned you need to modify slightly you geometry.
Your problem lies on vertex 22 and vertex 15. Line and circle are tangential which generates sharp angle. I would sweep face formed from vertex 13; 9 ;15 and 22, with very small vector in the direction normal to this surface.
