The filter bag is the core of the bag filter, which realizes high-efficiency dust removal through surface filtration and dust initial layer, and regenerates the capacity through periodic dust removal to ensure the continuous and stable operation of the equipment.
Product Description
Normal temperature and medium temperature filter materials are suitable for most conventional working conditions.
Features: good mechanical properties, wear resistance and low cost.
Limit temperature: 150°C for short time and 120°C for long-term use.
Disadvantages: not resistant to strong acid and alkali hydrolysis.
Application: The most common normal temperature filter material, which is used for dry and non-chemically corrosive flue gas in steel, cement and wood processing.
Features: excellent chemical resistance, especially acid and alkali resistance. Limit temperature: 190°C for short time and 160°C for long-term use. Disadvantages: poor oxidation resistance (life will be shortened when the oxygen content is more than 10%).
Application: The working conditions of sulfur oxides (SOx) such as coal-fired boilers and garbage incinerators are one of the standard for bag dust removal in power plants.
Features: hydrolysis resistance and chemical resistance are better than polyester, and the cost is moderate.
Limit temperature: 140°C for short time and 125°C for long-term use. Disadvantages: it is not resistant to high temperature, and its wear resistance is average.
Application: Suitable for working conditions with moderate temperature, little water vapor and chemical corrosion, such as dryers and coal mills.
The high-performance high-temperature filter material is suitable for higher temperature or harsh environment.
Features: excellent high temperature resistance, large fiber specific surface area and high filtration efficiency.
Limit temperature: 260°C for short-term use and 240°C for long-term use. Disadvantages: not resistant to hydrolysis (easy to be damaged in high temperature and high humidity environment) and expensive.
Application: high temperature and low humidity flue gas such as cement kiln head and kiln tail and carbon black production.
Features: good temperature resistance and wear resistance.
Limit temperature: 204°C for a short time and 190°C for a long time. Disadvantages: not resistant to hydrolysis and strong acid.
Application: Asphalt mixing, iron and steel smelting and other high temperature and dry working conditions.
Features:with excellent chemical corrosion resistance and high temperature resistance, smooth surface and good dust removal effect.
Limit temperature: 260°C for short-term use and 230°C for long-term use. Disadvantages: the price is very expensive, and the mechanical strength (tensile and wear resistance) is slightly poor.
Application: Waste incineration, chemical industry, carbon black and other most demanding high-temperature and highly corrosive working conditions.
