Abstract Pulsed-jet cleaning is recognized as the most efficient method to regenerate bag dust collectors traditionally used in industrial processes to control the emission of particulates. In this study, non-woven needle felt filter bags with and without a film coating material have been analyzed considering different geometries (different number N of pairs of pleated filter bag sides) in the frame of dedicated low-pressure pulsed-jet cleaning experiments. The flow structure inside the bag and the response characteristics of its wall have also been analyzed numerically through a computational fluid-dynamics/structural-dynamics (CFD-CSD) unidirectional fluid-solid coupling method. As shown by the experiments, the peak pressure… More >
