Working principle of the dust collector dust collector allows the flue gas to enter the device in the tangential direction, and the dust particles are separated from the gas due to the centrifugal force, so as to achieve the purpose of purifying the flue gas. The airflow in the cyclone is rotated many times and the line speed of the airflow is also fast, so the particles in the swirling airflow are subjected to much greater centrifugal force than gravity. For cyclone dust collectors with small...
