Dust removal method comparison analysis table
Mechanical dust removal | Wet dust removal | Filter dust removal | Electricity dust removal | Dry fog dust removal | |
concept | A device that separates and settles dust and air by mechanical force. Including three types: gravity sedimentation chamber, inertial sedimentation chamber and rotary dust collector | A device that uses liquid droplets or liquid film to wash the dust-containing airflow to separate and settle the dust and the airflow. Including wet scrubber and high-pressure spray dust suppression two types. | It is a device for filtering and separating dust-containing air through a fabric or packing layer. Including bag type dust collector and particle layer dust collector two types. | The high-voltage electric field is used to charge the dust particles, and the dust and the airflow are separated and settled under the action of Coulomb force. | The compressed air is used to atomize the water into water mist particles below 10μm, which combine with the inhalable dust to agglomerate, settle, and suppress the dust at the source of pollution. |
