“…The electric field altered the dust deposition pattern within the bag, yielding a much lower pressure drop than that found in a conventional bag. 5 This is a new method for calculating the complex, time-dependent gas flow rates and pressure drop in baghouses. In addition to accounting for the flow resistance of the fabric and duct cake, the approach also included the effect of connective ducting, dampers, and valves on the dynamics of the gas flow.…”

The pressure drop of ladder vanes in a baghouse could be reduced by decreasing the vane number and adjusting the inclined angle of the vane. Two types of flow distributors were utilized to test pressure drop caused by the structure of a baghouse. The pressure drops were measured by an inclined manometer under various filtration velocities. The purpose of this study is to understand the improvement effect of pressure drop saving for the traditional ladder vanes.Experimental results showed that the pressure drop of the Vane 3-1 configuration (flow distributor with three vanes perpendicular to the inlet flow) was higher than that of the Empty configuration (without flow distributors). The Vane 3-1 configuration could not reduce the pressure drop because of the barrier effect. By reducing the number and adjusting the angle of the vanes, the barrier effect was decreased, and the pressure drop of the Vane 2-1 configuration was much lower than that of the Vane 3-1 configuration. The largest difference in pressure drop between Vane 2-1 and Vane 3-1 was 1.702 cm w.g. at a filtration velocity of 4.17 cm/sec and, in terms of percentage, is 18.52% corresponding to a filtration velocity of 2.25 cm/sec. The improvement effect on the pressure drop saving for Vane 3-1 was significant. INTRODUCTIONThe baghouse is one of the oldest, simplest, and most efficient methods for removing solid particulate contaminants from a gas stream. A baghouse is capable of providing high collection efficiencies for particles as small as 0.5 µm and will remove a substantial quantity of those particles as small as 0.01 µm. This inherently high efficiency makes filtration one of the most attractive air pollution control techniques.
