The structure of wood dust removal is simple, easy to manufacture, install, and maintain. It is mostly used to remove particles larger than 3 μ m. The parallel multi tube cyclone dust collector device also has a dust removal efficiency of 90~for particles larger than 3 μ m. Wood dust removal equipment has low investment and operating costs, and has been widely used to separate solid and liquid particles from airflows, or to separate solid particles from industrial bodies. Under normal operating conditions, the centrifugal force acting on particles is 5-2500 times that of gravity, so the efficiency of cyclone dust collectors is significantly higher than that of gravity settling chambers. The mechanism of settling is to make the dusty airflow rotate, use centrifugal force to separate and capture dust particles from the airflow, and then use gravity to make the dust particles fall into the ash hopper. The cyclone dust collector consists of a cylinder, a cone, and inlet and outlet pipes. It has a simple structure and is easy to manufacture, install, and maintain. Wood dust collectors have been widely used to separate solid and liquid particles from airflow, or to separate solid particles from liquids.
