摘　　要：根据袋式除尘器除尘原理,结合煤粉工业锅炉系统特征,从袋式除尘器的清灰方式及经济性等方面分析了脉冲喷吹式除尘器和气箱式脉冲除尘器在煤粉工业锅炉系统中的适用范围。结合内蒙古神东集团寸草塔二矿其中一台煤粉工业锅炉袋式除尘器滤袋氧化失效情况分析,总结出适用于煤粉工业锅炉系统中袋式除尘器结构特点及运行维护中影响袋式除尘器的因素,为日后设计、安装、使用除尘器提供了参考。Analyze the scope of pulse jet dust collector and air box pulse dust collector system in pulverized coal industrial boilers through investigating the principle and deashing modes of bag filter, characteristics of pulverized coal industrial boiler system as well as the practical application of collectors. Taking one bag filter in Cuncaotao NO. 2 coal mine as research object, its main problem is that the filter bag lose effectiveness due to oxidation. According to the transformation of bag filter, provide its appropriate structure and maintenance methods, which is beneficial for design, installation and use of bag filter.
