Design and performance evaluation of a new cyclone separator

This paper presents the design and performance characteristics of a new type cyclone separator. The design of this cyclone is based on the idea of improving cyclone efficiency by increasing the vortex length. This cyclone differs from a classical cyclone with the separation space. Instead of conical part, the separation space of this cyclone consists of an outer cylinder and a vortex limiter. A model of this cyclone has been manufactured and tested. Collection efficiency and pressure drop of this cyclone were measured under different operational conditions. Experimental results were compared with the conventional cyclones. The effects of the position of the vortex limiter on the cyclone performance were also investigated.

► This study introduces a novel design of tangential inlet cyclone separators.
► The length of the new cyclone can be increased easily, if required.
► High collection efficiency can be obtained by adjusting the cyclone length.
► Efficiency of the new cyclone is higher than that of the conventional cyclone.
► Fractional efficiency curves of the new cyclone are steeper than the others.
