دليل اختيار مجمع الغبار الكيسي للغلاية

Boiler dust collector is key industrial equipment used in various boiler systems. Their main function is to filter and capture particulate matter from flue gases. This process effectively removes dust and improves emission quality, enhancing air quality and aiding environmental protection.

Why Modern Boilers Require Advanced Dust Collection

Today’s industrial boiler dust collectors (commonly called بيوت الأكياس أو فلاتر الأكياس) are critical for achieving >99.9% particulate removal efficiency, ensuring compliance with EPA, EU IED, and China’s Ultra-Low Emission standards. These systems handle:

✔ Coal-fired boilers (pulverized coal/stoker-fired)
✔ Biomass boiler emissions (high-moisture flue gas)
✔ Waste-to-energy plants (corrosive gas streams)

6 Critical Factors for Selecting Boiler Dust Collectors

1. Boiler Specifications Analysis

Coal boilers: Match filter media to coal type (e.g., PPS+PTFE bags for high-sulfur coal)
Biomass boilers: Require hydrophobic filter bags (e.g., polyester with nanofiber layer)
Rated capacity: Size baghouse for peak flue gas volume +20% margin

2. Emission Compliance Requirements

Region	PM Standard	Key Regulation
USA	≤10 mg/Nm³	EPA Subpart Db
EU	≤5 mg/Nm³	BREF LCP 2017
China	≤10 mg/Nm³	GB 13271-202X

3. Dust Property Considerations

نوع الغبار	Particle Size	Recommended Solution
Coal fly ash	0.1-50µm	Pulse-jet cleaning + PTFE membrane bags
Biomass ash	1-200µm	Offline compartment cleaning
Lime dust	<5µm	Pre-coating system

4. Process Integration Tips

Optimal location: التثبيت after air preheater (120-180°C ideal for baghouses)
Ductwork design: Maintain 15-20 m/s velocity to prevent ash deposition

5. Climate Adaptation Features

Arctic sites: Heated enclosures + siliconized filter bags
Tropical plants: Anti-hydrolysis media + condensation sensors

6. Special Hazard Solutions

Explosive dusts: NFPA-compliant explosion vents + conductive bags
Acidic gases: Fluoropolymer-coated cages + chemical pre-treatment

How Baghouse Dust Collectors Work

Gas Inlet: Flue gas enters through flow distribution baffles
الترشيح: Particles captured on أكياس الترشيح (efficiency down to 0.3µm)
التنظيف: 0.5-0.7MPa pulse jets dislodge dust cake
Discharge: Ash falls to صمام دوار for sealed removal

Technical Advantages:

✓ 260°C continuous operation (glass fiber bags)
✓ <500Pa pressure drop with optimized pulse sequencing
✓ 5+ year bag life with proper pre-coating

FAQ Section

Q: How often replace boiler filter bags?

A: Typically 3-5 سنوات depending on:
• Gas temperature (<160°C ideal)
• Cleaning frequency (optimize pulse interval)

Q: Baghouse vs ESP for boilers?

A: Baghouses better for:
• Submicron particles
• High resistivity dust (>10¹⁰ Ω·cm)
• Variable load conditions

Q: Reducing maintenance costs?

A: Implement:
✔ مراقبة الضغط التفاضلي
✔ Automatic damper controls
✔ Predictive maintenance sensors

الخاتمة
