A mechanical ReCyclone® (ReCyclone® MH) is made up of a Hurricane and a particle separator (straight-through cyclone), placed downstream of the cyclone - called the "recirculator".
The main purpose of the recirculator is to reintroduce the fine uncaptured particles into the cyclone after they have been driven to the outer walls of the recirculator by centrifugal forces.
While this tangential gas stream is enriched with particles, the axial gas stream exhausting to the stack is cleaned of particles. Recirculation is achieved through an additional fan.
Since the recirculation system only serves the purpose of dust separation (and not of collection), the particles are exclusively collected in the cyclone and the need of rapping mechanisms is thus avoided.
Efficiency increases due to recirculation and agglomeration of very small particles with larger ones coming directly from the process. A ReCyclone® MH decreases emissions of Hurricane cyclones alone by 40 to 60 %. As with cyclone systems, ReCyclone® MH systems are very robust, do not have temperature limitations and do not have moving parts to be frequently changed.
Finally, recirculation control provides the benefit of handling variable process flow rates very well.
