Description of the Cyclone.
For the separation of suspended substances in a fluid
current, the Cyclone Separator is based on the prin
-
ciple of mechanical separation by means of centrifugal
force (Cyclone Separator Principle).
The fumes sucked by a fan located downstream of the
Cyclone Separator are forced to move in a tangentially
inside a
cylinder.
The solid particles, carried by the fluid current, are
launched against the cylinder walls where, due to the
force of gravity acting against them, they lose speed
and fall.
It is possible to improve the separation capacity of a
cyclone separator sub-dividing it into multiple smaller
cyclones, considering that if the walls travel at the
same speed, the angular speed of the particles is
inversely proportional to the wall’s radius. The cen
-
trifugal force increases with the angular speed square,
therefore the friction on the walls of a cyclone with a
smaller diameter also increase.
The Cyclone Separator consists of a fume input cham-
ber in which small cylinders, composed of cylindrical
hoppers equipped with a system that forces the fluid
current to move in a rotary manner, are installed at
the bottom.
The fumes, after having traveled a certain part of the
cylindrical hopper, are forced to change direction and
go up into vertical ducts that, crossing over the input
chamber, release them into a plenum from which they
are then sucked by a centrifugal fan.
The solid parts, separated from the fumes by the cen
-
trifugal force and by the abrupt change in direction
are accumulated in a bucket placed at the base of the
cylinder outlets.
