Gas Pretreatment Equipment -Cyclone Separator

The Cyclone separator, as efficient gas and solid separation equipment, is widely used for the primary separation of natural gas and coal-bed gas. It is mainly used to remove the solid impurities and dust particles carried by the delivered gas medium, to ensure the normal operation of natural gas pipeline and equipment.

Operating principle

The gas entrained solid particles enter into cyclone from the tangential inlet of upper part of cyclone along the wall to bottom with high speed rotation, and becomes the inner upper cyclonic flow by turning back after reaching the bottom, discharging from the exhaust port of cyclone separator.

Due to the action of centrifugal force, dust particles entrained by gas flow increasingly go towards the lower cavity of cyclone separator in the process of rotation with gas flow, and move down with their own weight, so as to discharge from the outlet of bottom of cyclone separator; the gas not containing solid particles with small centrifugal force discharges from the top of the cyclone.
