POWFRAX Ceramic Filter Candles Technology Analysis
POWFRAX Ceramic Fiber Filter Tube Technology Analysis
Product Overview
POWFRAX ceramic fiber filter tubes are high-efficiency filtration elements made from ceramic fiber as the core material. They are widely used in ceramic fiber filter tube dust collectors and integrated dust-NOx removal systems, suitable for:
✔ High-temperature flue gas purification
✔ Acidic component removal
✔ Multi-pollutant synergistic treatment
Core Technologies
1. Gradient Pore Structure
- Utilizes axial layered fabric-forming technology to achieve uniform pore distribution
- Porosity >80%, enhanced by nanoscale pore-forming techniques for precision filtration
2. High-Temperature Adaptability
- Standard tubes withstand 200–1000°C flue gas temperatures
- Waterproof-coated tubes for **<200°C** applications
- Compatible with high-temperature ceramic fiber coatings
3. Integrated Ceramic Functionality
- **≥95% acid removal efficiency** via surface adsorbent cake layer
- Dust purification ≤10mg/Nm³
- Supports simultaneous desulfurization & denitrification
