[0003] Dust collectors mainly remove dust particles from the air through physical or physicochemical methods. Their working principles include using physical forces such as gravity, inertia, centrifugal force, and high-voltage electric fields to charge dust particles and collect them under the action of electric field forces. Industrial dust collectors are widely used in metallurgy, mining, cement, thermal power plants, building materials, casting, chemicals, pharmaceuticals, tobacco and other fields. They can effectively remove dust and exhaust gas generated in the production process, improve air quality, protect workers' health, and reduce corporate production costs.
