Classification of Industrial Dust collecting equipment

Dust collectors can be divided into many types according to different classification methods, for different working conditions and handling different dust.

1. Dry and wet conditions of the collection smoke classification
When the dust is dry, you can choose to use the following dust removal equipment: gravity dust collector, inertia dust collector, dry electrostatic precipitator, bag filter, or cyclone dust collector.

When the dust appears slurry, you can choose to use the following dust removal equipment: water film dust collector, foam filter, the impact of dust collector, Venturi tube dust collector, or wet electrostatic precipitator.

2. Dust efficiency classification
Low dust removal equipment (<60%): inertial dust collector, gravity precipitator, water bath precipitator
Medium Dust Removal Equipment (60-95%): Cyclone Dust Collector, Water Film Dust Collector, Self-excited Duster, Spray Duster
Good efficient dust removal equipment (>95%): electrostatic precipitator, bag filter, Venturi tube dust collector, air filter

3. Working status classification
According to the dust collector working condition in the dust removal system, the dust remover can also be divided into positive pressure dust collector and negative pressure dust catcher two kinds. Then the temperature is divided into high and low temperature dust collector and high temperature dust collector two categories. According to the size of dust can also be divided into small dust collector, medium-sized precipitator, large dust collector and large dust collector.

4. Dust removal mechanism and different function of dust
Based on "environmental protection equipment classification and naming" (HJ / T 11-1996) method points, dust collector is divided into the following seven types.

① gravity and inertial dust removal devices include: gravity settling chamber, baffle-type dust collector.
② cyclone dust removal devices include: single-tube cyclone dust collector, multi-cylinder cyclone dust collector.
③ wet dust removal devices include: spray-type precipitator, impulse precipitator, water film dust collector, foam precipitator, ramp gate dust collector, Venturi tube dust collector.
④ filter layer dust collector, including: particle layer dust collector, porous material dust, paper filter, fiber-filled filter.
⑤ bag dust removal devices include: mechanical vibration dust collector, electric vibration dust collector, sub-room backflush dust collector, nozzle blowback dust collector, vibration dust collector, pulse jet dust collector.
⑥ electrostatic dust removal devices include: plate electrostatic precipitator, tubular electrostatic precipitator, wet electrostatic precipitator.
⑦ combined dust collector, including: In order to improve dust removal efficiency, often "setting coarse dust removal device in the former level , setting fine particle dust removal device in the latter," the various types of series combination of dust removal device.

In addition, with the increasingly stringent air pollution control regulations, sometimes gas dust removal device will increase the function of flue gas desulfurization, derived from flue gas desulfurization device.
