The medium-temperature compound needled felt series filter bags are widely used as filtering materials in the industrial dust removal field. Specifically designed to adapt to medium-temperature working conditions of 120ºC-200ºC, they are made by compounding multiple high-performance fibre materials and undergoing special technological treatments. These filter bags feature high filtration efficiency, stable temperature resistance, and excellent mechanical strength, making them suitable for the purification of various industrial flue gases and dust.

I. Core Characteristics

  • Moderate Temperature Resistance Range
    They can withstand continuous temperatures of 120ºC-200ºC for a long time, with an instantaneous temperature resistance up to 220ºC (depending on the specific material combination). This enables them to meet the needs of medium-temperature flue gas filtration scenarios such as boilers, metallurgy, chemical industry, and waste incineration.
  • Advantages of Composite Materials
    They are usually composed of two or more types of fibres (such as polyester and acrylic, polyester and aramid, etc.), combining the characteristics of different fibres:
    • Polyester fibres provide good wear resistance and mechanical strength.
    • Acrylic fibres enhance acid resistance and temperature resistance.
    • A small amount of high-performance fibres (such as aramid) can improve anti-aging properties and extend service life.
  • High Filtration Efficiency
    Adopting the needling forming process, the fabric structure is dense with uniform pore distribution. The filtration efficiency for dust particles larger than 0.5μm can reach over 99.5%, which can effectively control the dust emission concentration and meet strict environmental protection standards.
  • Corrosion Resistance and Adaptability
    For acidic and alkaline flue gases commonly found in medium-temperature working conditions (such as waste gases containing sulphur oxides and nitrogen oxides), the acid and alkali resistance can be improved through fibre modification or post-treatment (such as impregnating PTFE coating), reducing the damage to filter bags caused by chemical corrosion.
  • Good Air Permeability and Ash Cleaning Performance
    The reasonable fibre ratio and needling density design ensure filtration accuracy while maintaining low operating resistance, facilitating compressed air ash cleaning, reducing the risk of filter bag blockage, and lowering equipment energy consumption.

II. Differences from Other Filter Bags

  • Compared with normal-temperature filter bags (such as pure polyester needled felt), they have a higher upper temperature resistance limit, can adapt to medium-temperature flue gases, and avoid filter bag melting or aging caused by high temperatures.
  • Compared with high-temperature filter bags (such as PPS, PTFE needled felt), They have lower costs, are suitable for scenarios where the temperature does not meet high-temperature standards, and have better cost performance.
