1. Selection & Design

Baghouse dust collector: Low filtration speed for fine/damp/sticky dust. Reserve 5%–10% invalid cloth area and 20%–40% air volume margin. Select filter bags per temperature, humidity, corrosion and explosion conditions. High dust concentration gas can be directly treated by pulse baghouse dust collector without pre-dedusting.

2. Working Condition Risk Control

High temperature: Strictly follow bag temperature limit and equip cooling facilities to prevent burning.
Dew & blocking: Keep gas temperature above dew point; adopt hydrophobic media for high humidity.
Corrosion: Use anti-corrosion filter materials and shell protection.
Explosion: Adopt explosion-proof baghouse dust collector with anti-static bags, grounding and explosion relief devices.

3. Equipment & Cleaning

Prioritize long-bag low-pressure pulse type. Ensure tight sealing to avoid leakage. Adopt differential pressure priority + timing auxiliary cleaning. Avoid over-pulsing; keep pulse air dry and clean.

4. Operation & Maintenance

Start fan first, delay cleaning and shutdown after production. Monitor differential pressure: rising = blockage/poor cleaning; sudden drop = bag damage/leakage. Discharge ash regularly and replace broken bags timely. Install PLC temperature and differential pressure alarm.

5. Common Misunderstandings

Reasonably match filtration area: excess causes energy waste, shortage causes excessive emission. Old baghouse dust collector can be renovated by replacing core parts while reusing original shell, no full replacement needed.
