Non-powered Dust Removal Device Attached Underneath a Train Cabin in a Subway Tunnel

In megacities, a subway system is a powerful means of public transportation, carrying people every day. Due to wear of train wheels and rails, dust is heavily generated and dispersed in tunnels and platforms. For the improvement of air quality in subway tunnels, a non-powered dust removal device consisting of two inertial separators, such as a louver and baffle, was designed. This device can be installed underneath the train cabin to remove dust as soon as it is generated. Prior to design of the device, distributions of airflow velocity and dust concentration underneath the train cabin during the operation of the subway train were investigated. Average airflow velocity was found to be approximately 26% of train speed during the cruising period. The fractional dust removal efficiency and pressure drop of the lab-scale dust removal device were tested in a wind tunnel. Removal efficiency of particles smaller than 10 μm is approximately 60% at 4 m/s.
