The cyclone recovery system is an essential part for powder coating booth which requires fast color change, especially in automatic production line, it offers fast cleaning efficiency and great recovery rate up to 98%. A complete recovery system includes cyclone separator and filter secondary recovery unit.
Most powder overspray are collected when air stream passing the cyclone for re-utilization, while after-filter unit is used to capture the superfine powder particulates and achieve 100% separation, ensure only no-particle air vented to atomsphere. Fiter cartridges has self-cleaning function controlled by pulse soleniod valves. Each filter cartridge is fitted with a rotary wing to help cleaning that ideally extends filter life.
Cyclones shapes upper barrel part and lower cone part. Generally, it uses the principle of centrifugal sedimentation to separate powder from air stream
1 Air stream suspended with powder coating particles enters to the cyclone from booth chamber, it is a suction movement due to the centrifugal fan installed in the secondary recovery unit.
2 Air stream swirls in the cyclone and powder particles are thrown towards the cyclone wall by centrifugal force.
As there is airflow outside of the cyclone, its downward sedimentation brings the separated particles to the cone bottom.
3. Powders is then recovered in a bottom tank where can be transfered automatcially through a powder supply equipment, in order to mixed with fresh powders fed back to the system
