Bag filter is an environmental protection equipment widely used in the industrial field, mainly used to capture and filter dust particles in the air to protect the environment and human beings. The working principle of the bag filter is to filter the dust through the bag, so as to achieve the purpose of purifying the air. In the bag filter, the bag is a key component, and the choice of material directly affects the energy and service life of the dust collector.
The main materials of the bag filter are as follows:
Polyester fiber: Polyester fiber is a synthetic fiber with high strength, wear resistance, acid and alkali resistance, and high temperature resistance. Cloth bags made of polyester fibers have good breathability, tensile resistance and abrasion resistance, and are suitable for various working conditions. Polyester fibers also possess electrostatic energy, which can effectively remove dust particles. Polyester fiber bags are widely used in bag filters.
2.Polypropylene fiber: Polypropylene fiber is a synthetic fiber with high strength, wear resistance, acid and alkali resistance, and corrosion resistance. Cloth bags made of polypropylene fiber have good abrasion resistance, tensile resistance and breathability, and are suitable for various working conditions. Compared with polyester fiber, the electrostatic energy of polypropylene fiber is poor, but for general industrial dust, polypropylene fiber cloth bags have been able to meet the requirements of use.
3.Polytetrafluoroethylene (PTFE): Polytetrafluoroethylene is a polymer material with excellent characteristics such as extremely high precision, extremely low coefficient of friction and strong chemical corrosion resistance. Bags made of PTFE are abrasion-resistant, tensile and breathable, making them suitable for extremely harsh operating conditions. PTFE bags are expensive to manufacture and susceptible to temperature and humidity, limiting their wide application.
4.Glass fiber: Glass fiber is an inorganic non-metallic material with high strength, high modulus, excellent wear resistance and chemical corrosion resistance. Fiberglass bags have good abrasion resistance, stretch resistance and breathability, and are suitable for various working conditions. Fiberglass bags have poor antistatic energy, which can make dust difficult to remove.
5.Nano filter material: Nano filter material is a new type of filter material with high efficiency filtration energy manufactured by nanotechnology. The cloth bag made of nano filter material has extremely high filtration accuracy and low resistance loss, which is suitable for occasions with high requirements for air quality. The high quality of nano filter material and the complex manufacturing process limit its promotion in the market.
The material selection of the bag of the bag filter needs to be comprehensively considered according to the actual working conditions, use requirements and cost budget. Different materials have their own characteristics and advantages and disadvantages, so when choosing a bag material for a bag filter, you should make the right decision based on the specific situation.
