Abstract: This work addresses the issues of high dust concentration and humidity in coal transportation systems by utilizing plastic filter boards as the key filtering material. Based on parameters such as airflow, resistance, and wind speed, a structural design for the plastic board dust removal system is proposed. Through four stages of experiments focused on system resistance and dust removal performance, conducted under actual working conditions with an airflow of 1500 m³/h, the performance of the dust removal device under different operating conditions was systematically evaluated. Through iterative design and optimization of the operational scheme, a dust removal device for coal transportation systems was ultimately developed that features stable operating resistance, high dust removal efficiency, and reduced maintenance workload. The results indicate that during the loading of inferior coal, the dust removal system maintains stable resistance, with the outlet dust concentration measured at approximately 0.1 mg/m³ and resistance around 3.2 kPa, effectively meeting the needs for on-site use. The research findings provide important theoretical foundations and methodological support for dust control in coal transportation systems and contribute to improving the energy efficiency of coal transportation, offering significant economic benefits.
