Advancing Marine Air Quality: Efficacy and Optimization of Experimental Helical Cyclonic Filter for Particulate Matter Reduction in Ship Emissions

Authors evaluate the performance of an experimental helical cyclonic filter aimed at reducing particulate matter emissions from ships. With increasing concerns over air pollution from maritime sources, innovative solutions are essential. The helical cyclonic filter, designed with a multi-channel structure and distinct deposition zones, was tested under various operational conditions to assess its efficacy. Results indicate that the filter effectively captures larger particles (sizes 1.0 µm and above), significantly reducing their counts at the outlet. However, it is less effective in trapping smaller particles (below 0.5 µm), as evidenced by an increase in counts for sizes 0.3 µm and 0.5 µm at the outlet. This suggests that while the filter facilitates the agglomeration of smaller particles into larger ones, it does not capture them efficiently. The study highlights the need for further optimization of the filter design to improve capture efficiency for smaller particles. Integrating additional technologies, such as cold plasma or electrostatic precipitators, could enhance the overall effectiveness. Future research should also explore long-term performance and maintenance requirements in typical naval industry environments. In conclusion, the helical cyclonic has potential for reducing larger particulate emissions but requires enhancements for finer particles. Advanced research and technological integration are recommended to develop a comprehensive air quality management solution in the naval sector.
