Abstract
This study investigates the influence of operational parameters on the performance of a laboratory-scale pulse-jet baghouse filtration system, focusing on dust cake structure, residual pressure drop, and filtration cycle duration. Using polyethylene (PE) filter media and 3-μm PMMA particles, experiments were conducted under varying relative humidity (RH), tank pressures (1, 2, and 4 kg/cm2), and with or without a Venturi tube. Results show that residual pressure drop increases progressively due to incomplete dust cake removal, with lower RH (20 %) exacerbating dust adhesion through enhanced electrostatic charging, leading to denser dust cakes and shorter filtration cycles. The inclusion of a Venturi tube at 2 kg/cm2 improved cleaning efficiency, achieving performance comparable to 3–4 kg/cm2 without a Venturi. Higher tank pressures reduced residual pressure buildup and extended filtration durations, though benefits diminished beyond 2 kg/cm2. Application of the Kozeny-Carman model revealed a decrease in model-derived dust cake porosity post-cleaning, indicating a transition to more compact structures. These findings provide guidance for energy-efficient operation of industrial baghouses through optimization of RH control and pulse-jet conditions.
