P84 Filter Bag

P84 High-Temperature Resistant Filter Bag

The P84 high-temperature resistant filter bag is crafted from polyimide fiber using a needle-punching process. This innovative design offers exceptional resistance to high temperatures, acids, and alkalis, making it an ideal choice for demanding industrial environments. The P84 filter bag, also known as the polyimide filter bag, effectively collects micro-particles with minimal pressure drop.

Features of P84 Filter Bags

High-Temperature Resistance: Unique polyimide fibers withstand temperatures up to 536°F (280°C), making them suitable for challenging environments in industries such as cement, lime, and metal.

Enhanced Surface Area: The tri-lobal fiber cross-section increases surface area, improving dust release and reducing pressure drop.

Durability and Longevity: Exceptional durability extends the service life of the filter bag, minimizing downtime for replacements. This ensures uninterrupted operations and higher productivity.

Optimal Air Quality: The P84 filter bag helps maintain superior air quality while keeping systems operating at peak efficiency in industries like power generation and cement.

Productivity Enhancement: Upgrading to Darko’s P84 filter bag boosts filtration processes, driving industry-leading productivity.

Applications of P84 Filter Bags

P84 filter bags are primarily used in flue gas purification across various industries, particularly in processes with high emission concentration requirements. Key applications include:

Cement Production Metal Smelting & Foundries Waste Incineration

In cement plants, these filter bags are crucial for dust collection systems, effectively capturing cement dust and other particulates generated during production.

P84 filter bags filter metal oxides, dust, and fumes produced during melting and casting in metal smelting and foundry operations.

Waste incineration plants utilize P84 filter bags in their filtration systems to control emissions of particulate matter and pollutants from burning waste materials.

Power Generation Chemical & Pharmaceutical Industries Hazardous Waste Incineration

In thermal power plants, these bags are employed in boiler systems and flue gas cleaning units to remove ash and other particulates from exhaust gases.

P84 filter bags are used in chemical processing and pharmaceutical manufacturing facilities to control emissions of fine particulates and hazardous substances.

Facilities incinerating hazardous waste rely on P84 filter bags to ensure compliance with environmental regulations by capturing hazardous particulates and preventing their release into the atmosphere.
