P84 composite felt filter bag

P84 composite felt filter bag

P84 composite felt filter bag is a high-performance filter material made by combining high-temperature fiber P84 with other fiber materials. P84 is a synthetic fiber material made from PolyminoidP-Phenylene Terephthalamide, which has excellent temperature resistance, corrosion resistance, and mechanical strength.
P84 composite felt filter bags are widely used in the filtration and purification of various industrial flue gases, such as high-temperature process equipment such as steel smelting, cement production, incinerators, dryers, etc. Its main function is to capture particles and dust in the flue gas to ensure the cleanliness and safety of the environment.
The P84 composite felt filter bag has the following characteristics and advantages:
1. Good filtration effect: P84 fiber has a fine fibrous structure and a high specific surface area, which enables the filter bag to effectively capture and retain particulate matter. P84 fiber material also has good anti-static performance, reducing the adhesion of dust on the surface of the filter bag.
2. High temperature resistance: P84 fiber has a melting point of up to 260 ℃, which can maintain its stability and mechanical properties in high temperature environments. Therefore, P84 composite felt filter bags can be used for a long time in high-temperature process equipment, reducing the frequency of filter bag replacement and maintenance costs.
3. Corrosion resistance: P84 fiber has good corrosion resistance to chemicals such as acids, alkalis, and oxidants, and can cope with complex industrial flue gas components. This makes the P84 composite felt filter bag have a longer service life in process equipment with corrosive gas emissions.
4. Excellent mechanical strength: P84 fiber has high tensile strength and tear resistance, allowing the filter bag to withstand high pressure difference and particle impact. This also makes the P84 composite felt filter bag more durable, less prone to damage and deformation.
5. Easy to clean and maintain: The surface of P84 composite felt filter bag is smooth and not easy to adhere dust and dirt. When the filter bag needs to be cleaned, it can be cleaned using low-pressure gas backflushing or wet washing, which can be reused and extend the service life of the filter bag.
The manufacturing process of P84 composite felt filter bags is relatively complex, with the main steps including raw material pretreatment, fiber mixing, spinning and spinning, and heat setting. Among them, P84 fiber can be mixed with other fiber materials to obtain filter bags with different performance through different proportions of mixing. In the textile process, specific weaving techniques are used to form a three-dimensional network structure of fibers, increasing the surface area and filtration efficiency of filter bags.
In summary, P84 composite felt filter bags play an important role in the purification and treatment of industrial flue gas due to their excellent high-temperature resistance, filtration effect, and corrosion resistance. With the improvement of environmental protection requirements and the development of industrial technology, there are increasingly high requirements for the performance and stability of filter bag materials. It can be foreseen that the application of P84 composite felt filter bags in the industrial field will be further expanded.
