Bag Filter Customized Industrial Dust Removal And Filtration Equipment Dust Collector

The working principle of the pulse dust collector is as follows:
Intake and pre-separation: Dust-laden gas enters the dust collector through the intake port and first encounters

the inclined plate and baffle between the intake and exhaust ports. The gas flow then turns and flows into the ash

hopper, while its speed slows down. Due to the effect of inertia, coarse dust particles in the gas directly fall into

the ash hopper, achieving initial separation.
Filtration stage: Fine dust particles turn upward with the airflow and enter the middle and lower boxes. Dust

accumulates on the outer surface of the filter bags. The filtered gas enters the upper box to the clean gas

collection pipe, and then is discharged into the atmosphere through the exhaust duct and exhaust fan. As

the filtration time increases, the dust layer on the filter bags continuously thickens, and the resistance of the

dust removal equipment rises.
Ash cleaning trigger: When the equipment resistance rises to the set value, the ash cleaning device is activated.

The compartmental-based stop-air pulse jet cleaning technology is widely applied, and its process is as follows:
Cut off the airflow: First, close the clean air outlet duct of this chamber to ensure that the filter bags are in a state

without airflow passing through, preventing secondary adsorption of dust during ash cleaning.
Pulse jet: Open the pulse valve, and compressed air rapidly expands in the upper box within an extremely short

period of time, flowing into the filter bags. The expansion and deformation of the filter bag cause vibration. At the

same time, under the scouring effect of the reverse airflow, the dust adhering to the outer surface of the filter bag

is stripped off and falls into the ash hopper.
Dust discharge: The shut-off valve's closing time ensures that the dust settles in the ash hopper after injection,

preventing it from adhering to adjacent filter bags along with the airflow. After the ash cleaning is completed, the

electromagnetic pulse valve closes and the lift valve opens, and the chamber returns to the filtration state. Each

room is cleaned in sequence to complete one cleaning cycle.
Control system: The exhaust valve, pulse valve and ash discharge valve, etc. are fully automatically controlled by

a programmable controller. The frequency and intensity of ash cleaning are adjusted according to the equipment

resistance or the set time.
