Dust collectors are devices used to separate dust from flue gas.

The performance of dust collector equipment is expressed by the amount of gas it can handle, the resistance loss of gas passing through the collector, and the dust removal efficiency. Additionally, the price of the dust collector, operational and maintenance costs, lifespan, and ease of operation and management are also significant factors in evaluating its performance.

Dust collectors are categorized into five types based on their working principles.

(1) Mechanical dust collectors include gravity dust collectors, inertial dust collectors, centrifugal dust collectors, etc.

(2) Washable dust collectors include water bath dust collectors, foam dust collectors, Venturi tube dust collectors, and water film dust collectors, etc.

(3) Filter-type dust collectors include bag dust collectors and granular bed dust collectors, etc.

(4) Electrostatic precipitator.

(5) Magnetic Dust Collector.
