Pulse jet airflow is the main means of cleaning dust in the filter cartridge dust collector. The action of the air jet causes the cartridge filter element to expand and shake, and the dust on the cartridge is peeled off and falls into the ash hopper, thus maintaining the clean and efficient filtration performance of the cartridge. In order to more accurately reflect the impact of the blowing airflow on the filter cartridge, the static structural module (Static Structural) in ANSYS Workbench is employed to perform the fluid-solid coupling of the cartridge pulse soot removal, and the resulting pressure is applied to the cartridge. This allows for the conclusions related to the solid mechanics of the filter cartridge under the pressure of pulse blowing to be drawn. By comparing the simulation results with the same blowing time and different blowing distances, the impact of the blowing airflow on the pleated structure of the cartridge can be determined. Firstly, Fluent simulation is employed to obtain the pressure change within the cartridge. It is observed that although the pressure exhibits slight numerical discrepancies under varying blowing distances, its distribution trend remains consistent: the airflow descends along the length of the filter element and subsequently spreads along the radial direction, the static pressure within the cartridge accumulates from the bottom in an upward trajectory. The lower portion of the cartridge exhibits a relatively elevated static pressure, while the upper section displays a comparatively reduced pressure. The accumulation of pressure within the cartridge is discernible. The static structure module in ANSYS Workbench is employed to couple the pressure derived from the Fluent simulation conducted in the preceding step to the pleated structure of the filter cartridge. This enables the acquisition of the total deformation, elastic strain, and maximum shear stress values of the pleated structure of the filter cartridge and their distribution law through simulation under the same time set. In the experimental range, when the blowing distance is 150 mm, the best values of each parameter of the airflow acting on the pleated structure of the cartridge are obtained: the total deformation is 0.133 27 μm, the elastic strain is 3.018×10-4 μm, and the maximum shear stress is 222.69 Pa.
