Abstract

Abstract

In this paper, the pulse-jet cleaning for filter cartridge dust collector was taken as the research object to investigate the influence of the peeling off of the dust cake on the pulse-jet cleaning performance. The numerical model of pulse-jet cleaning was built using CFD software and the cleaning flow field was simulated and analyzed. The results showed that the pulsed-jet pressure formed in the lower part of the filter cartridge was significantly higher than that in the top part. Compared with the fixed dust cake condition, the pulse-jet intensity was lower, the uniformity was worse and the air flow rate penetrating the filter was larger under the dust cake peeling off condition. With the increase of initial total filtration resistance ΔP_t (less than 1000 Pa), the pulse-jet intensity and uniformity increased, and the air flow rate penetrating the filter cartridge decreased. These parameters went stable when ΔP_t was more than 1000 Pa. These results provided theoretical references for the research and design of the pulse-jet cleaning dust collectors.
