Advanced Filtration Material Aramid Nonwoven Fabric For Cement Kiln Dust Filtration
Aramid nonwoven fabric is an advanced filtration material widely used in cement kiln dust collection systems, particularly for cement kilns' kiln head and kiln tail. Known for its exceptional high-temperature resistance, high strength, and excellent filtration efficiency, Aramid nonwoven fabric is an ideal solution for filtering harmful dust and gases emitted from cement manufacturing processes. It helps reduce emissions, improve air quality, and ensure compliance with environmental regulations.
Key Features and Advantages of Aramid Nonwoven Fabric in Cement Kiln Dust Filtration:
-
Outstanding High-Temperature Resistance: Aramid nonwoven fabric can withstand continuous temperatures of up to 260°C, making it perfect for the high-temperature environment of cement kilns, both at the kiln head (where gases are hot) and the kiln tail (where exhaust gases are still heated).
-
Superior Strength and Durability: Aramid fibers, such as Kevlar and Nomex, are known for their high tensile strength and tear resistance. This makes Aramid nonwoven fabric extremely durable under the constant stress of high-velocity gas flows and abrasive dust particles in cement plants.
-
Effective Dust Filtration: The fabric offers excellent filtration efficiency for fine particulate matter and dust (PM10, PM2.5) generated during cement production. This is critical for reducing harmful emissions and improving air quality around cement kilns.
-
Chemical and Abrasion Resistance: Aramid nonwoven fabric is resistant to many chemicals, including acids and alkalis commonly found in cement plant emissions. Its resistance to abrasion also helps maintain the material’s integrity in challenging environments.
Technical Parameters:
-
Material: Aramid fibers (e.g., Nomex, Kevlar)
-
Temperature Resistance: Up to 260°C (500°F)
-
Filtration Efficiency: >99% for fine particulate matter (PM2.5, PM10)
-

-
Air Permeability: 100 to 500 L/m²/s, depending on fabric thickness
-
Surface Treatment: Optional surface coatings (e.g., PTFE coating) for enhanced dust release
Applications in Cement Kiln Dust Filtration:
-
Kiln Head Dust Filtration: At the kiln head, where gases can reach temperatures above 200°C, Aramid nonwoven fabric is used to capture fine particulate dust before it is released into the atmosphere. The fabric ensures that particulate emissions are kept well below regulatory limits.
-
Kiln Tail Exhaust Filtration: At the kiln tail, where the gas temperature is lower but still challenging, Aramid nonwoven fabric helps filter out remaining dust and contaminants from exhaust gases. This contributes to a cleaner production process and reduces environmental pollution.
-
Pollution Control Systems: In cement manufacturing, Aramid nonwoven fabric is widely used in baghouse filters and other air pollution control systems to ensure effective capture of dust, smoke, and harmful particles, helping cement plants meet strict emission standards.
Frequently Asked Questions (FAQ):
Q1: What makes Aramid nonwoven fabric ideal for cement kiln dust filtration?
A1: Aramid nonwoven fabric is ideal for cement kiln applications because of its excellent high-temperature resistance (up to 260°C), high strength, and dust filtration efficiency, all of which are critical for handling the tough conditions at cement kilns.
Q2: How long does Aramid nonwoven fabric last in a cement kiln environment?
A2: Thanks to its durability and abrasion resistance, Aramid nonwoven fabric lasts longer than many other filtration materials. Its robust performance in harsh conditions reduces the need for frequent replacements, making it a cost-effective choice.
Q3: How does Aramid nonwoven fabric help in reducing emissions from cement kilns?
A3: Aramid nonwoven fabric captures fine particulate matter and harmful gases produced during cement production, ensuring that the emissions are filtered and that the plant meets environmental regulations.
Q4: Can Aramid nonwoven fabric handle the highly abrasive dust in cement kilns?
A4: Yes, Aramid nonwoven fabric is specifically designed to handle the abrasive dust in cement plants. Its abrasion resistance ensures long-term durability even in environments where dust particles can cause damage to other filtration media.
