1. Core Features of High-Temperature Dust Filter Cartridge

Our High-Temperature Dust Filter Cartridge combines advanced heat-resistant materials and precision manufacturing technology, boasting outstanding performance that outperforms conventional filtration products in harsh high-temperature environments:

8226. Exceptional Heat Resistance & Thermal Stability: Manufactured from premium heat-resistant materials, the filter cartridge offers tailored temperature tolerance for different scenarios—PPS withstands 160-190℃, PTFE up to 260℃, Nomex aramid fiber 200-220℃, and special ceramic fiber can endure over 400℃ even for short periods. It maintains structural integrity and stable filtration performance under rapid temperature changes (up to 100℃/min) without cracking or deformation, eliminating the risk of filter failure caused by extreme heat.

8226. High Filtration Efficiency & Ultra-Low Emissions: Equipped with a gradient pore structure and optional PTFE coating technology, the filter cartridge achieves a filtration precision of 0.1-0.5μm, with PM2.5 capture efficiency exceeding 99.95%. It effectively reduces dust emissions to ≤10mg/Nm³, and even as low as 5mg/Nm³ for special configurations, fully complying with global environmental protection standards for industrial emissions.

8226. Corrosion & Wear Resistance: The selected filter materials and surface coatings (such as PTFE coating) provide excellent resistance to acidic/alkaline gases (e.g., HCl, SO₂) and abrasive dust particles commonly found in industrial flue gas. The metal fiber or ceramic structure enhances wear resistance, with a service life 5-8 times longer than ordinary organic filter materials, reaching 5-10 years under normal operating conditions.

8226. Reusable & Easy Ash Cleaning: Integrated with pulse jet cleaning technology, the filter cartridge supports online regeneration without shutdown. The optimized surface structure reduces dust adhesion, allowing thorough ash removal with a low backblowing pressure of 0.4-0.7MPa. It can be repeatedly cleaned and reused, significantly reducing replacement frequency and operational costs.

8226. Low Resistance & Energy Efficiency: The rational structural design and high porosity (up to 80% for metal fiber materials) ensure a low initial pressure drop of 300-600Pa and stable operating resistance below 1200Pa. This minimizes energy consumption of induced draft fans, achieving energy-saving operation while maintaining large air handling capacity.

8226. Safety & Customizable Adaptability: Equipped with explosion-proof and flame-retardant features (compliant with ATEX and UL standards), it is safe for applications involving combustible dust. We offer comprehensive customization of material, length, diameter, filtration precision and end cap design to match specific equipment and working conditions, such as high-humidity or high-corrosion environments.

3. Key Industry Applications and Usage Methods

Our High-Temperature Dust Filter Cartridge is specifically designed for high-temperature flue gas treatment in various industries, providing targeted dust removal solutions for different production processes. The specific applications and usage methods are as follows:

3.1 Cement Industry

Cement kilns generate flue gas with temperatures ranging from 300-350℃ (peak up to 550℃), high dust concentration (exceeding 100g/Nm³) and complex components including alkali metal salts and sulfides. The High-Temperature Dust Filter Cartridge is mainly used for dust removal in kiln head and kiln tail flue gas systems. Usage Method: Select ceramic fiber or PTFE coated filter cartridges adapted to ultra-high temperatures; install them in modular dust collectors with pre-installed coolers if necessary to control flue gas temperature within the filter's tolerance range. Regularly monitor pressure difference and perform pulse jet cleaning when resistance exceeds 1200Pa to maintain filtration efficiency. The filter cartridge effectively reduces emissions to ≤10mg/Nm³, meeting environmental standards while protecting downstream equipment.

3.2 Metallurgical Industry

In metallurgical processes such as steelmaking, sintering and smelting, flue gas is characterized by high temperature (150-300℃), high dust hardness and corrosive components. The filter cartridge is widely used for dust removal in converter flue gas, sintering machine exhaust and blast furnace gas treatment. Usage Method: Choose Nomex aramid or PPS filter cartridges with excellent wear and heat resistance; install them in dust collectors equipped with spark arresters to prevent filter damage from high-temperature particles. Optimize pulse cleaning frequency according to dust concentration (shorten intervals for sticky dust) to avoid filter clogging. The product ensures stable operation in high-temperature and high-wear environments, extending equipment service life.

3.3 Chemical & Waste Incineration Industry

Chemical production (e.g., coal chemical, petrochemical) and waste incineration generate flue gas containing acidic/alkaline corrosive gases and toxic pollutants, with temperatures ranging from 200-300℃. PTFE coated High-Temperature Dust Filter Cartridges are the preferred choice for their strong corrosion resistance. Usage Method: Install the filter cartridge in dust collectors with pre-treatment systems (e.g., lime neutralization for acidic gases); ensure the filter housing is equipped with insulation layers to prevent condensation and corrosion. Utilize online pulse cleaning to maintain continuous operation without shutdown, which is crucial for continuous chemical production lines. The filter cartridge achieves efficient dust removal while capturing harmful particles, ensuring compliance with environmental regulations.

3.4 Power Plant & Other High-Temp Fields

In coal-fired power plants, boiler flue gas treatment requires filter cartridges that balance heat resistance and low emissions. The High-Temperature Dust Filter Cartridge is used for pre-filtration and fine dust removal in flue gas desulfurization and denitrification systems. Usage Method: Select PPS filter cartridges for 160-190℃ flue gas; install them in large-scale modular dust collectors with intelligent pressure difference monitoring. Regularly inspect filter integrity and replace damaged cartridges promptly to maintain emission standards. Beyond power plants, it is also applied in glass manufacturing, asphalt mixing and other high-temperature industries, providing reliable dust control solutions for various high-heat processes.
