Objectives: Many types of dust collector are used for industrial ventilation, with the most common types being the cylinder bag filter system, rectangular bag filter system and cylinder type cartridge filter system. The cylinder type cartridge bag filter, which has more filtering area than other types of bag filter, can increase the pulse time and extend the useful lifeof the filter. This can save operational costs and installation area.
Materials: This study used cylinder type cartridge bag filter equipment and tested the impact of vibration level and filter pressure with different pulse jet cleaning conditions. The final, cleaning efficiency was calculated through input dust mass and cleaning dust mass
Conclusions: Two optimum cleaning condition groups were found. The first condition group was 3 kgf/cm2 pulse pressure, 15 cm pulse distance, 0.2 s pulse time with an H-10 type nozzle. The second condition group was 3 kgf/cm2 pulse pressure, 15 cm pulse distance, 0.3 s pulse time with an H-10 type nozzle
