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

The performance of dust collector equipment is expressed by the amount of gas that can be processed, the pressure loss during gas flow through the dust collector, and the dust removal efficiency. Additionally, the price of the dust collector, operation and maintenance costs, the duration of its service life, and the ease of operation and management are also significant factors in evaluating its performance.

Dust collectors are divided into the following five categories based on their working principles:

(1) Mechanical dust collectors include gravity dust separators, inertial dust separators, centrifugal dust separators, and others.

(2) Washing-type dust collectors include water bath dust collectors, foam dust collectors, Venturi tube dust collectors, water film dust collectors, etc.

(3) Filter dust collectors include bag dust collectors and granular layer dust collectors, etc.

(4) Electrostatic precipitator.

(5) Magnetic dust collector.
