Abstract

Background and Objective: Pulse Jet baghouse systems are of interest due to their high Filtration velocity. They are used as inlets from the top and bottom. The purpose of this study was to compare the Pressure Drop and collection Efficiency at different Inlet Positions in a baghouse. Materials and Methods: In this experimental study, a pilot baghouse system was designed at 12ft/min permeability for MDF particles. For each inlet, after several Filtration-cleaning periods, the Pressure Drop was measured by a manometer. Isokinetic sampling was carried out by Grimm monitor model 1. 108 for the determination of the Efficiency. To observe the behavior and Tyndall effect of the particles, a light and safety glass were used in one dimension of the baghouse. Results: The mean of Pressure Drop during the Filtration-cleaning was reported as 3 cmWG in the bottom inlet. In addition, the means of the topexpansion inlet and top-flanged inlet were observed to be 2. 42 and 2. 57 cmWG, respectively; however, the particles were settled on the bottom in the expansion. The Efficiency means of the top-expansion and top-flanged inlets were 99. 995% and 99. 994%, respectively, which were significantly higher than that reported for the bottom inlet (99. 974%). Nevertheless, after several Filtration-cleaning periods, the Efficiency values of the bottom, topexpansion, and flanged inlets were obtained as 99. 99%, 99. 97%, and 99. 96%, respectively. There was no significant difference in the means of total Efficiency among different inlets. Conclusion: The collection Efficiency values were similar for baghouse with the inlet from the top and bottom. The Pressure Drop for baghouses with top inlets was lower than that reported for the baghouses with bottom inlets. It is recommended to use top inlets in case of predominantly fine particles with low density or in the presence of a pre-separator, and bottom inlets are suggested in case of large particles. However, due to the slight difference of Pressure Drop and more functional limitation of the top inlet, the bottom inlet is preferred in practice.
