Background

A cyclone separator is a commonly used device for separating solid or liquid particles from a gas stream for cleaning the gas or recovering useful solid or liquid particles. The cyclone separator utilizes the rotary motion of the gas-solid two-phase fluid to throw solid particles or liquid drops with larger inertial centrifugal force to the outer wall surface, and then the solid particles or the liquid drops are separated from the airflow. The cyclone separator can form an outer cyclone and an inner cyclone positioned in the outer cyclone inside, solid or liquid particles gradually sink to the bottom of the cyclone separator after passing through the outer cyclone, and then gas is discharged out of the cyclone separator after rising again through the inner cyclone.
