A cone or cylindrical tube stack with narrow in-between gap circumferential surface swirling cyclone separator according to the present invention, creating swirling flow by flowing along the convex outer surface of the inner-stacked cone or cylindrical tube. The inner wall of the outer-stacked cone or cylindrical tube, which is a concave surface, serves as the wall for collecting fluid with larger or higher density particles that is opposite to the surface for swirling, which is disposed in accordance with the separation movement of larger or higher density particles that centrifuged from swirling by their inertial force. The distance that the particles travel towards the wall for collecting fluid with larger or higher density particles is short due to the narrow swirling and separating gaps, combined with the flow on the convex curved surface of the cone or cylindrical tube walls which pressure drag is low, this results in higher swirling speeds than those on the concave inner surface of conventional cyclone, significantly increasing the inertial force of particles centrifuged away from the swirling. Consequently, the separation efficiency of the cone or tube stack circumferential surface swirling cyclone separator according to the present invention is much higher than that of conventional cyclone separators. Especially in cases where the cyclone fluid separator according to the present invention is equipped with multi-stage separation, where the final stage utilizes multiple small cyclones, and in configurations where multiple cones are stacked and equipped with device for swirling and counter-flow separation, which convex fluid drainage ridges are installed on the wall for collecting fluid with larger or higher density particles, the ridges curving towards the side that the swirling flow flows to, sloping from the downstream edges of the cones or cylindrical tubes towards the upstream edges of the cones or cylindrical tubes, which counter to the swirling flow along the convex curved surface of the outer circumferential surface of cone or cylindrical tube. When working with a reverse swirling system, enabling to recycle multiple separation within the system before the fluid exits the separator, enabling high separation efficiency for separating various types of fluids mixed into emulsion or separating micron-level dust such as PM 2.5 from the air.
