Classification by core working principle
Mechanical dust collectors
Principle:Separates dust using gravity, inertia, or centrifugal force.
Representative equipment: Gravity settling chambers, cyclone dust collectors.
Characteristics: Simple structure and low cost; relatively low dust removal efficiency; often used for initial pre-dust removal stages.
Filtration-type dust collectors
Principle: Captures and adsorbs dust using filter media.
Representative equipment: Baghouse dust collectors, cartridge dust collectors, granular bed dust collectors.
Characteristics: Dust removal efficiency can exceed 99%; currently the most widely used type in the industrial sector.
Electrostatic precipitators
Principle: Uses a high-voltage electric field to charge dust particles, causing them to adhere to electrodes.
Characteristics: Low resistance; suitable for high-temperature, high-airflow conditions; relatively high initial equipment investment.
Scrubber-type (wet) dust collectors
Principle: Captures dust using water droplets or mist.
Representative equipment: Spray towers, Venturi scrubbers, water-film dust collectors.
Characteristics:Suitable for handling high-humidity, flammable, or explosive dust; capable of simultaneously removing certain gaseous pollutants.
