Thermal Power Station Filtration: ZTW Tech's Ceramic Solutions for Ultra-Low Emissions
Revolutionizing Thermal Power Station Filtration with Ceramic Integration
In the evolving landscape of thermal power station filtration, meeting stringent environmental regulations while maintaining operational efficiency presents a significant challenge. Traditional solutions like baghouses, electrostatic precipitators (ESPs), and separate SCR/SNCR systems often struggle with complex flue gas compositions, catalyst poisoning, and high maintenance costs. ZTW Tech addresses these challenges head-on with its pioneering Ceramic Integrated Multi-Pollutant Ultra-Low Emission Flue Gas Treatment System. This system represents a paradigm shift, moving from multi-stage, bulky equipment to a compact, unified solution centered on proprietary ceramic filter elements.
The Core Technology: Ceramic Filter Tubes & Catalysts
At the heart of ZTW Tech's system are two key components developed through extensive R&D:
- Ceramic Catalytic Filter Tubes/Cartridges: These elements combine flue gas denitrification (DeNOx) and fine particulate filtration in one step. The catalyst is integrated into the nano-porous ceramic matrix, allowing simultaneous NOx reduction (to N2 and H2O) and dust capture at temperatures typically between 300°C and 450°C. This eliminates the need for a separate, space-consuming SCR reactor and protects the catalyst from blinding and poisoning by fly ash.
- High-Temperature Dust Removal Ceramic Fiber Filter Tubes/Cartridges: Designed for applications where selective catalytic reduction is not required, these filter tubes offer exceptional durability and efficiency in harsh conditions. With a nanoscale pore structure, they achieve filtration efficiencies exceeding 99.99% for PM2.5 and finer particles, operating continuously at temperatures up to 900°C, far beyond the limits of traditional fabric filters.
Both types feature a high air-to-cloth ratio, low pressure drop, exceptional mechanical strength, and a proven service life exceeding five years, even in the presence of alkali metals, heavy metals, and acidic components that rapidly degrade conventional solutions.
System Advantages & Technical Superiority
ZTW Tech's integrated system delivers unparalleled benefits for thermal power station filtration and beyond:
- True Multi-Pollutant Control: A single system achieves ultra-low emission standards for particulate matter (PM), nitrogen oxides (NOx), sulfur oxides (SOx), hydrogen fluoride (HF), hydrogen chloride (HCl), dioxins, and heavy metals (e.g., mercury, lead). This consolidation drastically reduces the plant's footprint and capital investment compared to a "stack" of individual units for flue gas desulfurization, dust removal, and DeNOx.
- Overcoming Technical Bottlenecks: The system is specifically engineered to handle the toughest flue gas conditions:
- Catalyst Poisoning Resistance: The unique structure and composition of the ceramic catalytic filters mitigate deactivation caused by high concentrations of alkali (e.g., K, Na) and heavy metals (e.g., As) in fly ash from coal, biomass, or waste fuels.
- Handling Sticky & High-Fluorine Flue Gases: For challenging applications like aluminum smelting or glass manufacturing with high HF emissions, the system includes pre-conditioning stages and utilizes specially formulated ceramic materials resistant to acid attack, ensuring stable long-term operation.
- High-Temperature Operation: Eliminates the need for costly gas cooling before treatment and re-heating for plume buoyancy, improving overall thermal efficiency.
- Operational Efficiency & Cost-Effectiveness: The high filtration velocity (high gas-to-cloth ratio) means fewer filter elements are required, leading to a smaller vessel size. The low and stable pressure drop reduces fan power consumption. With a lifespan over 5 years and minimal maintenance requirements, the total cost of ownership is significantly lower than for bag filters, ESPs, or metal filters that require frequent replacement.
Application Spectrum: Beyond Thermal Power
While thermal power station filtration is a primary application, ZTW Tech's ceramic technology is versatile and dominant across heavy industries with stringent emission challenges:
| Industry | Key Challenges | ZTW Tech Solution & Benefit |
|---|---|---|
| Waste-to-Energy & Biomass | High moisture, fluctuating composition, sticky ash, dioxins, acid gases. | Integrated removal of dioxins (via catalytic destruction), acid gases, and dust. Stable operation despite variable feedstocks. |
| Glass & Ceramic Kilns | High-temperature flue gas, high fluorine/chlorine content, fine particulate (boron, alkali). | High-temperature ceramic fiber filters capture sub-micron fumes; acid-resistant formulations handle HF/HCl. |
| Steel & Sintering Plants | High-dust load, heavy metals, SO2, NOx from combustion and processes. | Catalytic ceramic filters achieve simultaneous DeNOx and dust control in sintering windboxes or furnace exhausts. |
| Non-Ferrous Metals (e.g., Al, Cu) | Extremely high concentrations of SO2, HF, and metal fumes. | Robust system design with pre-conditioning and high-activity catalysts for deep removal of acidic pollutants. |
