EDT offers
high-efficiency, reverse-flow cyclones for the main separation of
airborne powder for dry particle collection or recovery.
In spray dryer systems, particles entrained in the exhaust air leaving
the drying chamber must be separated and recovered to prevent air
pollution through powder emission to the atmosphere, and to achieve
maximum output from the spray drying system.
EDT reverse-flow dry cyclones are designed to operate under pressure or
operate under vacuum. Powder and air enter the cyclone tangentially
creating a spiral motion within the cyclone. The powder and air swirls
in spiral form down to the base of the cyclone, separating the powder
out at the cyclone walls. Powder exits the base of the cyclone while the
clean air spirals upwards along the axis of the cyclone passing out the
top.
Further collection of fine particles before discharge to the atmosphere
is achieved by secondary dry collection using a baghouse or secondary
wet collection using a wet scrubber. |
