Jet-cleaning experiment and simulation of a pulse-jet cartridge filter

By testing the jet-cleaning process of a filter cartridge ofΦ147×1 000 mm in size on a jet experiment platform, obtains a dynamic change curve of peak pressure by means of a data collection system. Adopting CFD to simulate the jet-cleaning process of the filter using an unsteady calculation method, gains the peak pressures at different pulse-jet times. The occurring time of positive peak pressure is gradually increasing along the length direction of the cartridge under a given jet pressure. The increase of the peak pressure in cartridge does not increase with the jet time and the peak pressure has a decrease trend when the jet time is longer than 60 ms. The variation trend of the peak pressure curve from simulation is accordant with the one from the experiment.
