摘要：

Pulse jet cleaning is often used with cartridge filters. However, pulse jet cleaning is non-uniform between filter cartridges under the same injection pipe. In this study, a pulse-jet cartridge filter was designed. The static pressures on the inner wall of the filter cartridges, the transient pressures below the nozzles, the pressure drops in the filter cartridges, the dust emission concentrations, and the filtration cycle length were investigated. In addition, a quality index was used to evaluate the filtration performance of the pulse jet cartridge filter. The nozzle diameters were optimized using the optimization ratio of 0.76, 0.87, 0.95, 1.11, and 1.31, respectively. After optimization, the nozzle diameters were 11.5, 10.5, 10.0, 9.5, and 9.0 mm along the airflow direction of the injection pipe. At a result, the uniformity of the composite pressures on the inner wall of the filter cartridges and the transient pressures below the nozzles were all significantly improved. Nozzle diameter optimization decreased the filtration pressure drop, prolonged the filtration cycle, and improved the dust collection efficiency. Furthermore, the quality index increased, and the filtration performance of the pulse jet cartridge filter was improved after optimization. (C) 2019 Published by Elsevier B.V.
