High-Efficiency Industrial Bag Dust Collector

High-Efficiency Industrial Bag Dust Collector is a widely used dust removal equipment in the industrial field.The following will introduce its structural composition,working principle,characteristics,and application fields:

Structural composition

Filtering system:composed of filter bags and supporting frames,it is the core component for dust removal.Filter bags are usually made of natural fibers,chemical fibers,or inorganic fibers,and the supporting skeleton is used to maintain the shape of the filter bag and ensure the filtration effect.

Dust cleaning system:mainly includes pulse spraying,mechanical vibration,reverse blowing and other types.The pulse jet cleaning system uses a pulse valve to instantly inject compressed air into the filter bag,causing the dust on the surface of the filter bag to fall off;Mechanical vibration type uses a mechanical device to vibrate the filter bag for dust cleaning;The reverse blowing type uses reverse airflow to shrink and deform the filter bag,shaking off dust.

Box:including upper box,middle box,and lower box.The upper box is equipped with an air outlet,the middle box is used to install filter bags,and the lower box is an ash hopper used to collect dust.

Air inlet and outlet system:The air inlet system guides the dust containing gas to enter the dust collector uniformly,while the air outlet system discharges the purified gas.

Working principle

Filtering stage:After the dusty gas enters the dust collector,large particles of dust fall directly into the ash hopper under the action of gravity and inertia,while the remaining dusty gas enters the filter bag filtration area.The dust is trapped on the outer surface of the filter bag,and the purified gas enters the upper box through the filter bag and is discharged from the air outlet.

Dust cleaning stage:As the filtration progresses,the dust on the surface of the filter bag gradually increases.When the resistance reaches the set value,the dust cleaning system starts to remove the dust on the surface of the filter bag and drop it into the ash hopper to restore the filtering performance of the filter bag.

characteristic

Advantages:High dust removal efficiency,stable up to 99.50%-90%,can effectively capture fine dust;Strong adaptability to the characteristics of dust,capable of handling dust of different properties,particle sizes,and concentrations;Simple structure,easy maintenance,stable and reliable operation,low failure rate;The processing air volume is large,and it can be designed and selected according to different working conditions.

Disadvantages:Sensitive to temperature,humidity,and corrosive gases;High pressure loss and high operating energy consumption;The service life of the filter bag is limited and needs to be replaced regularly.

application area

Widely used in industrial fields such as steel,cement,chemical,power,metallurgy,and building materials,it can be used for purifying dusty gases such as blast furnace gas,cement kiln tail gas,calcium carbide furnace tail gas,and coal-fired boiler flue gas.
