Principles and Applications of Dust Removal Equipment

   Dust removal equipment refers to equipment that separates dust from flue gas, also called a dust collector. Everyone has the experience of wearing a mask. A mask is a simple filtering and dust removal device. The dust removal mechanism of the dust removal equipment is very simple. It is the same as the dust removal mechanism of the mask, which is achieved through the mechanical interception of fly ash particles in the flue gas by the filter material. But in addition, the fly ash particles received first form a stable and dense ash layer (generally called filter cake or filter bed) on the surface of the filter material, which also plays a very good filtration role, especially for dust removal equipment that uses woven cloth as filter bags. This layer of filter bed plays the main filtration role.

　　Dust removal equipment is divided into the following five categories according to its working principle:

　 (1) Mechanical dust removal equipment includes gravity dust removal equipment, inertial dust removal equipment, centrifugal dust removal equipment, etc.

　 (2) Washing dust removal equipment includes water bath dust removal equipment, foam dust removal equipment, venturi dust removal equipment, water film dust removal equipment, etc.

　 (3) Filter dust removal equipment includes filter cartridges such as bag dust removal equipment and particle layer dust removal equipment.type dust collector.

　 (4) Electrostatic dust removal equipment.

　 (5) Magnetic dust removal equipment.
