A cyclone dust collector is a dry gas-solid separator that uses centrifugal force to remove dust particles from a dust-laden gas stream. Its core operating principle is this: the dust-laden gas enters the cylindrical body tangentially, creating a high-speed rotating vortex. Due to the difference in mass between the dust particles and the gas, the particles are thrown toward the cylinder wall by centrifugal force. They then fall along the wall due to gravity and are collected in the hopper at the bottom. The purified gas exits through the exhaust pipe in the center of the cylinder, thus completing the gas-solid separation.
