This study aimed to design and evaluate a dust collector capable of capturing particles smaller than 10 microns, addressing the critical challenge of reducing air pollution caused by industrial exhaust gases. Dust particles emitted from various industrial plants significantly contribute to air pollution and pose severe health risks. Filtration using nonwoven filter media has emerged as an effective technology for environmental protection. A series of experiments was conducted to evaluate the efficiency of nonwoven filters under varying operating conditions. The tests utilized filter materials with different air permeability properties in a pilot-scale dust collector. Measurements of filtration pressure drop and gas velocity revealed that the pressure drop increased with higher gas velocity but decreased with increased filter media permeability. The pressure drop was characterized by a second-order polynomial equation of filtration velocity, further linked to the Darcy-Forchheimer equation for porous media. The results demonstrated two distinct patterns of pressure drop increase influenced by air permeability. Filters with lower air permeability exhibited comparable pressure drop trends. The experimental data showed strong agreement with the modeled pressure drop values, achieving a coefficient of determination (R2) exceeding 0.989. This high level of accuracy underscores the effectiveness of the model for designing air filtration systems. © (2025), Int.
