Cyclone is a kind of dust removal device. Dust removal mechanism is to make the dust flow for the rotary motion, by effect of centrifugal force will be separated from the air flow and trapped in the wall, and then dust particles fall into the hopper bu gravity.
As the cyclone without internal mechanical parts, easy to operation, for larger than 10 microns dust particle separation efficiency can up to 95%, widelu used in grain industry as a medium-level purification equipment.
Dusty air enter the upper part of outer cylinder in a high speed. Then rotating in high speed between the top and bottom cone, outside and inside of the cylinder. During rotation, the dust particals was thrown to the outer cylinder inner wall and collided with the wall under the large centrifugal force. friction and gradually lose the speed, and then under gravity, along the cylinder wall to the cone part, Discharge ash discharge. When the airflow is near the bottom of the cone, the air can not flow out from the bottom due to the installation of the shut-off equipment at the outlet and begins to reverse the rise and then through the inner cylinder.
