Abstract:Bag dust collectors are widely used in non-ferrous smelting enterprises, and the common cleaning method for bag dust collectors is pulse jet cleaning. The operation effect of the pulse jet cleaning system has a significant impact on key indicators such as the resistance of the bag filter operation and the service life of the filter bag. Based on the actual operation situation of four bag filters under different operating conditions in a non-ferrous smelting enterprise, various adjustment measures made during the operation process, and the operation situation after transformation, the operation mode of the bag filter injection system in a non-ferrous smelting enterprise is analyzed and summarized Summarize and discuss the selection of injection gas source and other issues to improve the operation effect of bag filter.
