Application Of E-PTFE In Filter Material Dedusting

Nov 02, 2018

As the main equipment to control dust pollution, bag filter is a kind of traditional and efficient filter dust removal equipment. The application of expanded polytetrafluoroethylene membrane in bag filter is a new and efficient air filtration dust removal technology developed in recent years, which has been effective in preventing smoke and dust, superfine dust and air pollution. The fruit is remarkable. The bag filter made of expanded polytetrafluoroethylene (PTFE) membrane is made of two kinds of materials with different properties and processed by special technology. The surface layer of the bag filter is expanded PTFE, which is thin, compact, smooth and multi-microporous. It mainly plays a filtering role. It has changed the traditional concept of filtration. It is called membrane surface filtration, and the bottom filter material is traditional. The filter material or the cloth made of pure PTFE fibers, the cloth mainly plays the role of supporting the surface film and enhancing the mechanical strength. Compared with traditional filter media, the new filter media has the advantages of more uniform pore size, better stability, lower operating resistance and higher filtration efficiency. Even for submicron dust, the filtration efficiency still exceeds 99.9%. In addition, expanded polytetrafluoroethylene filter material can work in high humidity for a long time, and ash handling is also very easy. In addition, PTFE itself has excellent acid resistance, alkali corrosion resistance, high temperature resistance, high humidity resistance, oil resistance, pressure resistance, hydrolysis resistance and oxidation resistance, so it has incomparable advantages over other fiber membranes, such as coal-fired boilers, waste incinerators, dust removal purification, air filtration in construction materials and cement industry. The flue gas dedusting, especially in the field of filtration PM2.5, has wide application prospects.
