Cyclone separation is a technique of removing particulates from an air or gas stream, without the use of filters, through vortex separation. It is a simple device with no moving parts, cyclone separators use centrifugal forces generated by a rapidly spinning gas to separate solids from air. Dirty air entering the cyclone is forced into a spiral motion where the centrifugal forces push the particulates to the outer walls of the device where they can be collected and discharged. Cyclones can be used as precleaners ahead of bag houses and can be designed to handle a wider range of chemical and physical conditions than almost any other type of collection equipment.
