In industrial dust collection systems, dust filter bags play a crucial role in ensuring emission compliance and stable system operation. However, as operating time increases, filter bags tend to accumulate dust, oil stains, and chemical deposits, which gradually reduce filtration efficiency. To extend the service life of filter bags and reduce operational costs, a standardized cleaning process is essential. This article explains the complete cleaning process for dust filter bags.
1. Dust Removal: The First Step to Restoring Filter Bag Performance
The first stage of cleaning is dust removal, commonly done by high-frequency vibration. Proper vibration helps dislodge large dust particles from the fiber surface. It is critical to control vibration frequency and intensity to avoid loosening the fibers, which may affect the bag’s structural stability and filtration efficiency. Effective dust removal significantly improves the efficiency of subsequent cleaning steps.
2. Chemical Treatment: Removing Oil, Grease, and Persistent Contaminants
Filter bags contaminated with oil or chemical deposits require a chemical treatment process.
This includes:
Sample Testing – Using professional instruments to analyze the types of contaminants on the filter bag.
Chemical Selection – Choosing the right cleaning agents according to the contaminant characteristics.
Soaking Treatment – Immersing the filter bags in the cleaning solution to dissolve and remove oil and deposits effectively.
This process restores the air permeability of the filter bag without damaging the material.
3. Washing and Drying: Ensuring Dimensional Stability
After chemical treatment, the filter bags enter the main washing stage.
Key points include:
Using cleaning agents with strict and accurate formulation
Washing with low-temperature water to prevent fiber degradation
Controlling water flow to avoid mechanical damage
After washing, the filter bags are dried with hot air at approximately 110°C, which ensures proper drying while maintaining dimensional stability and preventing shrinkage or deformation.
4. Inspection and Repair
Once dried, the filter bags undergo several physical tests, including:
Air permeability
Strength
Visual inspection for integrity
If any wear, pinholes, or corrosion is detected, repair work is performed to ensure the filter bag meets operational requirements.
5. Final Quality Check and Storage
After passing strict quality inspection, the filter bags are packaged, labeled with certification, and sent to the warehouse for shipment.
Conclusion
A professional cleaning process not only restores the filtration performance of dust filter bags but also significantly extends their service life. This helps industrial users reduce maintenance costs, improve operational stability, and maintain efficient dust collection performance.
