The present invention relates to a cascading air wash particle system. In particular, this invention relates to separation of fine particulate matter from bulk solids, using static elimination and an airflow management system. A deduster for the separation of fine particulate matter from granules, pellets, and small parts that might be pneumatically conveyed. In one aspect, the invention features a pick-up wand that contains excess air ports to assure dilute phase conveying of the parts to the cleaner. The cleaner operates from a single air-conveying source, be it electrical or compressed air operated, to transport the bulk solids to the cleaner and to aspirate fine particles from the bulk solids. A linear funnel arrangement is also provided to direct nearly free fall, and air assisted direction of particles through the cleaner, the directed airflow and free fall to inclined surfaces enhances particle-collision intensity and flow direction for separation of fines from bulk solids. Additionally, a static eliminator system is used to directly expose the falling bulk solids to the ionizers without air assist or ducting arrangements. The ionizers are so positioned to optimize neutralizing charge transfer to the bulk solids, while being free of collisional impacts that might otherwise damage the corona emitters. |
