Dust collector working principles

(1) mechanical dust collector: This type of dust collector is the use of mass force (gravity, inertial force and centrifugal force, etc.) from the role of dust from the dust separation of the device. Gravity sedimentation chamber, inertial dust collector and cyclone 


(2) filter-type dust collector: This type of dust collector is to make dust-laden air through the fabric or porous packing layer for filtration separation device. Mainly a bag filter, particle layer dust collector.


(3) electrostatic precipitator: the main use of high-voltage electric field so that dust particles charged in the Coulomb force under the action of dust and air separation.Generally divided into dry and wet two categories, according to the charge and separation area of ​​the different layout , Can be divided into single-zone and double-zone electrostatic precipitator.


(4) wet dust collector: This type of dust collector is the use of droplets or liquid film dust particles from the dust separated from the device, divided into impact, foam tower, venturi and other dust collector.


(5) modular dust collector: This type of dust collector is mainly the use of a variety of purification mechanism integrated purification. General mechanical and filtration, mechanical and electrostatic, wet and static combination of the way.

In practice, often according to the level of dust efficiency will be divided into high efficiency dust, efficiency and inefficient dust collector, electrostatic precipitator, bag filter and some wet dust collector for the current wide application of three kinds of high efficiency Dust catcher, cyclone dust collector and other wet dust collector is a medium effect dust collector, gravity settler and inertial dust collector is a low efficiency dust collector.

According to the dust removal equipment, the dust removal equipment is divided into seven types:

(1) gravity and inertia dust removal device: gravity settling chamber, block

(2) cyclone dust collector: single cylinder cyclone dust collector, multi-cylinder cyclone dust collector. Wet dust collector: spray dust collector. Impulse dust collector. Water film dust collector. Foam dust collector.

(5) Bag filter: mechanical vibration of the dust collector, the use of dust, dust, dust, dust, dust, dust, dust, dust, dust, Electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator, electrostatic precipitator

(7) modular dust collector: In order to improve the efficiency of dust removal, often "in the former set of coarse particles dust removal device, after the fine particle dust removal device" series modular dust collector. In addition, with the increasingly stringent regulations on air pollution control, flue gas desulfurization device sometimes increase the function of flue gas desulfurization, derived from flue gas desulfurization equipment
