Numerical simulation of filter plate influence on flow field uniformity in dust collectors

With the acceleration of industrialization, dust pollution in industrial production is becoming increasingly severe. This poses significant threats to occupational health and environmental ecosystems. Cartridge dust collectors are widely employed in high-dust-concentration environments, including mining and tunneling operations. This is due to their efficient particulate removal capabilities and operational stability. However, flow field uniformity within these systems is critical in determining performance outcomes. Heterogeneous flow distributions may induce uneven particle dispersion and elevated flow resistance, which ultimately compromises filtration efficiency. This study used numerical simulation techniques to conduct a comparative analysis of flow field characteristics between filter plate and cartridge dust collectors. The results indicated that the filter plate dust collector significantly improved flow field uniformity. It increased air volume consistency by 6%. Additionally, air velocity fluctuations are notably reduced. Peak velocity differentials in the filtration area decreased by 17% compared to cartridge dust collectors. Turbulence intensity was generally lower across all cross-sections. There was minimal variation between adjacent filter plates. These findings not only demonstrated the influence of filter plates on flow field uniformity but also offered a theoretical foundation for the design and optimization of dust collectors. This could lead to improved performance of industrial dust collection systems, thus promoting occupational health and environmental protection.
