袋式除尘器用高性能滤料选择及应用

Selection and application of high performance filter bag for bag house filters

作为袋式除尘技术核心的滤料,其使用选择对整个过滤效率起了至关重要的作用。聚四氟乙烯(PTFE)滤料以其耐酸碱腐蚀、耐高温、抗氧化、不易水解、使用寿命长等特点被广泛应用在垃圾焚烧、燃煤电厂及冶金行业的烟气污染控制领域,是一种富有发展前景的滤料。

As the core of the filter bag dust collection technology,the collect selection of filter on the filtration effi- ciency plays an important role. Polytetrafluoroethylene（ PTFE ） filter have been widely used in the garbage incineration and metallurgical industry,coal-fired power plant flue gas pollution control areas was a full of prospects for development of the material because of its corrosion resistance, high temperature resistance, antioxidant, was not easy to hydrolysis, long life and other characteristics.
