“…Pui and colleagues have also performed laboratory and field measurements of industrial dust collectors (Liu et al, 1986c;Bergin et al, 1989;Fay et al, 1989), and have extended the work to include bioaerosol filtration (Kuehn et al, 1994;Kemp et al, 1995aKemp et al, , 1995b. Several papers from the doctoral dissertation of Liming Lo (Lo et al, 2008(Lo et al, , 2010a(Lo et al, , 2010b provide the basic criteria for the design of reversed-pulsed dust collector for cleaning dust-loaded filters.…”

Aerosol Science and Technology: History and Reviews captures an exciting slice of history in the evolution of aerosol science. It presents in-depth biographies of four leading international aerosol researchers and highlights pivotal research institutions in New York, Minnesota, and Austria. One collection of chapters reflects on the legacy of the Pasadena smog experiment, while another presents a fascinating overview of military applications and nuclear aerosols. Finally, prominent researchers offer detailed reviews of aerosol measurement, processes, experiments, and technology that changed the face of aerosol science. This volume is the third in a series and is supported by the American Association for Aerosol Research (AAAR) History Working Group, whose goal is to produce archival books from its symposiums on the history of aerosol science to ensure a lasting record. It is based on papers presented at the Third Aerosol History Symposium on September 8 and 9, 2006, in St. Paul, Minnesota, USA.

“…The research of reverse pulsing jet cleaning has been focused on the improvement of cleaning efficiency and quality for pleated filter cartridges by varying operational and pleating parameters (Calle et al, 2002;Lo et al, 2010a;Lo et al, 2010b;Bemer et al, 2013;Yan et al, 2013;Qian et al, 2014;Li et al, 2015a;Li et al, 2015b;Yan et al, 2015). The performance of pleated filter cartridges (with different pleat geometries and filter medium properties) under various cleaning conditions (i.e., cleaning mode and tank intensity) was investigated in a full-sized dust collector periodically cleaned by a reverse pulsing jet (Lo et al, 2010a). It was found that the pleat ratio (the ratio of pleat height to pleat pitch) had great influence on the cleaning efficiency of pleated cartridges and the tank pressure is critical for the pulsing jet cleaning.…”

“…Pre-coating (Bemer et al, 2013) and cone installation (Li et al, 2015a) of pleated filter cartridges have shown to have positive impact on the efficiency and quality of reverse pulsing jet cleaning. The optimization of nozzles (Yan et al, 2013;Qian et al, 2014;Yan et al, 2015) and tank pressure (Lo et al, 2010a;Yan et al, 2015) have also evidenced the reduction of incomplete cleaning or patchy cleaning under certain conditions. However, the poor cleaning quality and patchy cleaning near the head of filter cartridges remains an issue for reverse pulsing jet cleaning.…”

“…The calculation of pressure and flow fields around pleated cartridges has been performed to evaluate the efficiency of reverse pulsed-jet cleaning (Ahmadi and Smith, 2002;Lo et al, 2010a). Time-dependent 3D models were developed to explore the relationship between cleaning efficiency and filter pleating parameters.…”

“…Time-dependent 3D models were developed to explore the relationship between cleaning efficiency and filter pleating parameters. The average static pressure and static pressure distribution on the surface of cartridge filter media, which is difficult to be measured, were concluded as the good indicator for cleaning filter cartridges (Lo et al, 2010a). Numerical modeling of time-dependent gas flow field and pressure distribution in pulsing-jet cleaning of baghouse filters was also performed (Ahmadi and Smith, 2002).…”

Pleat structure and tight pleat spacing of pleated filter cartridges often lead to patchy cleaning when applying reverse pulsing technique process to regenerate filter media, consequently resulted in the decrease of the efficiency and quality of reverse pulsed-jet cleaning as well as the service lifetime of filtration units. For improving the non-uniform cleaning or patchy cleaning, a novel convergent trapezoidal pleat shape was used in multi-pulsing reverse flow cleaning. A transient 3D CFD simulation in a simple filtration system with a single filter cartridge was carried out under the four multi-pulsing modes. The effects of multi-pulsing flow cleaning on the cleaning efficiency and quality were systematically investigated. Compared with single-pulsing cleaning mode, the peak pressure differences at the upper regions all became positive because of the increased cleaning frequency, and thus which would be crucially important for improving the local cleaning mechanical stresses and cleaning efficiency. Moreover, the extra peak-pressure augment in the lower regions of filter cartridge also had a positive influence of local cleaning efficiency. For the multi-pulsing scheme of Waveform #4, the peak pressure difference at the section 4 increased by 11.2% than the single-pulsing scheme. The related action mechanism had high correlation with the interaction of residue gas and following jet. Finally, the improvement of the cleaning efficiency and quality are expected to be validated under the decreasing tank pressure and real permeability.
