Mechanical dust collectors have three categories: settling chamber, inertial dust collector and cyclone. The work of the settling chamber uses gravity, and the so-called gravity is the attraction of the earth to objects. The dust in the dust-containing gas is separated in the settling chamber by gravity. Inertial dust collectors use inertial forces to separate dust. The inertial force is the force that reflects the state of motion of the material itself, and changes the state of motion when the external force is applied.
Under the same force, an object with small inertia is more likely to change its motion state than an object with large inertia, that is, the obtained acceleration is relatively large, which is advantageous for dust separation with small inertia. The cyclone uses centrifugal force. The so-called centrifugal force refers to the centripetal separation force applied to an object that makes a circular motion. It is based on the reaction force in the rotating body, and the separation process using the centrifugal force to separate the heterogeneous system is generally called centrifugal separation.
It works according to the principle that the centrifugal force generated by the material with high mass and high rotation speed during the rotation process is also large.
