DeDusting System Configurations
Pelletron provides various system configurations for all kinds of industrial dust removal applications. Pelletron technicians recommend suitable system designs based on the customer demands for a clean end product. DeDuster® systems are available in open loop and closed loop versions, as well as in configurations for air tight systems with inert gas or clean room applications. Wash down versions for wet cleaning are also available upon request.
Open Loop Dedusting System with Cyclone
An open loop system is recommended for processes with frequent product changes or for lines with frequent color changes in order to avoid cross contamination. Filtered fresh air is pushed from a wash air fan into the DeDuster® supplying the cleaning air. A second exhaust air fan pulls the dusty air into a cyclone or baghouse dust collector. The dust is separated in a dust collector and dropped into the dust container. The cleaned air is then released into the atmosphere.
A closed loop system is recommended for standard operations with the same or similar product grades or for inert gas applications. A push/pull wash air fan supplies the wash air and pushes it into the DeDuster®. The dust is separated by the baghouse dust collector and dropped into a dust container. The cleaned air is returned to the fan.
Open Loop Dedusting System with Baghouse Filter
Closed Loop Dedusting System with Cyclone - CCD-system (patented)
As an alternative to a baghouse, there are also Compact Cyclonic DeDuster® (CCD) systems available, a closed loop application solution with a cyclone and an inline filter. The dust is separated by the cyclone and dropped into a dust container. Remaining fine particles are separated using an inline filter. The cleaned air is returned to the fan.
