Pulse Jet Dust Collector
The pulse jet bag filter achieves a dust removal efficiency of 99.99%. It adopts a PLC control system to automate the cleaning process. The main structure consists of truss frame, hopper, filtration chamber, clean air chamber, and pulse-jet cleaning device. Dust-laden gas undergoes pre-dust removal through the inlet air distribution duct, while purified gas is filtered through the outer surface of the filter bags.

1. Structural Composition
The pulse-jet bag filter features a modular housing design, comprising eight core components:
Support truss
Dust collection hopper
Middle filtration chamber
Upper clean air chamber
Pulse-jet cleaning system
Access platforms & ladders
Inlet/outlet ductwork
PLC control cabinet
2. Intelligent Cleaning Control
PLC automation governs the cleaning sequence with two operational modes:
Time-based cycling (fixed intervals)
On-demand pressure differential control (ΔP-triggered)
Solenoid valves precisely release compressed air bursts (0.2-0.5MPa) while maintaining continuous online operation – no process interruption required.

Pulse Jet Bag Filter Working Principle
The pulse-jet bag filter operates by directing dust-laden gas through an inlet into the hopper where coarse particles settle, while finer particles flow upward into the filtration chambers. As the gas passes through filter bags, dust accumulates on their outer surfaces, and clean air exits through the upper chamber to the exhaust system. For cleaning, individual compartments are isolated from airflow, and compressed air pulses dislodge the dust into the hopper, with PLC-controlled valves ensuring efficient, automated operation that prevents redeposition of dust onto adjacent bags.
Filtration Principle
Dust-laden gas enters through the inlet and passes through the hopper, where larger particles are separated by inertial forces and directly collected in the hopper. The gas then proceeds to the bag filtration zone within the housing. As the gas permeates through the filter bags, dust particles are captured on the outer surface of the bags. Purified gas exits through the bag openings into the upper chamber and is discharged via the outlet.
Pulse-Jet Cleaning Principle
As filtration continues, dust accumulation on the bags increases, raising system resistance. When resistance reaches a preset threshold, the cleaning cycle initiates:
Pulse Activation: Solenoid valves open, releasing compressed air into the upper chamber in milliseconds.
Bag Expansion: The rapid air injection causes bag expansion and vibration.
Dust Dislodgement: Combined with reverse airflow, dust layers are stripped off and fall into the hopper.
Cycle Completion: Valves close, restoring normal filtration. This process repeats sequentially across all chambers, with one full rotation constituting a cleaning cycle.
