A pleated filter cartridge with an additional pleated filter cone installed on the cartridge base, i.e., a pleated cone filter cartridge, has been proposed to increase the filtration area and to improve medium regeneration by reverse pulsed-jet cleaning. In this study, the pulsed-jet cleaning performance of a pleated cone filter cartridge in a dust collector was investigated using a diffusion nozzle (as compared to that of a round nozzle). The effects of tank pressure (TP), jet distance (JD), and inner cone height (HC) on the distribution of static pressure acting on the inner surfaces of the cone filter cartridges were evaluated. The filtration pressure drops and emitted dust concentration of cartridges during the dust collector operation were also measured. It was found that, using a diffusion nozzle, the pulsed-jet pressure at the upper portion of the filter cartridges was increased, compared to that of a round nozzle, particularly for cartridges with a low HC and a short JD setting (e.g., a factor of 7.0 was observed when HC = 560 mm and at a JD setting of 150 mm). The pulsed-jet cleaning of a pleated cone filter cartridge using a diffusion nozzle can decrease the residual filtration pressure drop, prolong the cleaning interval, and reduce the average dust concentration emission from cone filter cartridges.HIGHLIGHTS
