City construction will produce a large amount of garbage. Incineration is a widely used way to deal with garbage. However, this method has many disadvantages. The gas generated by combustion will causing pollution to the air. Faced with this problem, PTFE dust filter bags made of High-efficiency PTFE composite filter material can be used to filter the flue gas before it is discharged to ensure the interception of harmful particles.
Waste incineration is currently one of the important application fields of pure PTFE coated dust removal filter bags. The waste incineration process inevitably produces a large amount of pollutants. These pollutants have the following characteristics: there are particulate matter, acidic gases, heavy metals and organic highly toxic pollutants in the flue gas; the flue gas has high moisture content, high dew point temperature, and poor filtration. The device is prone to condensation; high and low temperature flue gases exist alternately; the particulate matter produced by deacidification treatment easily absorbs moisture, causing difficulty in dust cleaning and pipe blockage; the flue gas is highly corrosive. The filter bag made of needle-punched felt filter material with PTFE as the base fabric and PTFE fiber as the surface layer and coated with PTFE microporous membrane can achieve good results in the flue gas purification of waste incineration power plants.
High-efficiency PTFE composite filter material is formed by compounding a layer of polytetrafluoroethylene (PTFE) film on the surface of ordinary filter material A new type of filter material. This film is equivalent to a “primary dust layer”. Material exchange is carried out on the surface of the membrane, and good filtration can be performed at the beginning of use. The unique three-dimensional network structure of the film prevents dust from passing through, and there is no risk of pore clogging. This type of filtration is called “surface filtration”. High-efficiency PTFE composite filter material not only can achieve near-zero emissions, but also because the film is non-sticky and has a small friction coefficient, the powder cake will automatically fall off, ensuring long-term stability of equipment resistance, thus giving full play to bag dust removal The superiority of the filter makes it an ideal filter material choice.
PTFE dust removal filter bag is made of polytetrafluoroethylene fiber as raw material through acupuncture, high temperature shaping, impregnation coating, slitting and other processes. Filter bags. Due to its excellent hydrolysis resistance, alkali resistance, organic acid resistance, mineral acid resistance, oxidation resistance and other characteristics, PTFE dust filter bags are widely used in the field of waste incineration, coal-fired power plants, cement industry, and laboratory purification. field.
In addition, dust removal filter bags help power plants, steel plants, cement plants, waste incineration plants, etc. reliably control particulate matter emissions and pollution, and are resistant to It has good corrosivity and good thermal stability, meets the factory’s pollution dust interception needs, helps control emissions and optimize processes.
The currently independently developed high-efficiency PTFE composite filter material is the core material of PTFE dust removal filter bags. It has reliable filtration levels of H13-U16 and can meet high, medium and primary efficiency filtration levels. , low wind resistance, low energy consumption and wide chemical applicability.
