• • The novel blowpipe achieves stable cleaning at 60 ms, reducing cleaning cycle time and enabling short-duration, high-frequency cleaning that minimizes filter bag wear.
• • Maximum total pressure peak of 3939.22 Pa occurs at front orifices, while minimum static pressure of -134.23 Pa at side orifices is offset by maximum dynamic pressure, ensuring effective cleaning.
• • Cleaning intensity is higher in the upper filter section and at side orifices; side-orifice regions show superior blowing uniformity compared to front orifices.
• • Compared to conventional nozzles and built-in rotators, the novel blowpipe offers enhanced cleaning performance and uniformity, though upper-section cleaning is not fully resolved.
