“…Tokarek and Bernis [4] installed electrostatic precipitators [5] in Paris metro stations, which can be used to remove dust particles near the platforms.Li and Jo [6] built beam-type electric filters [7] in the mechanical ventilation and air conditioning (MVAC) system of the metro, which led to an increase in the number of particles passing through while improving the efficiency of removing fine particles.Ryu [8] and others applied an air curtain [9], which reduced the concentration of pollutant dust and particles in the tunnel and improved the ventilation efficiency.Son [10] et al reduced the discharge of particles by installing a magnetic filter [11] on the subway ventilation equipment.Jung [12] sampled dust particles in some subway stations in Seoul and showed that most of the particles in the air were less than 10 µm. Subsequently, Sim [13] installed a louver dust collector at the bottom of the subway based on Jung's study [14] for bottom dust, especially coarse particles, and improved the efficiency of PM10 removal.…”

Subway vehicle blowing dust removal generally has poor blowing operating conditions, serious environmental pollution and manual work intensity and other problems, which has long plagued the operation and use of the sector. With the development of society, the subway vehicle blowing dust removal device towards the direction of intelligent development, increasingly perfect. To date, many scholars and universities have conducted research on the subway vehicle blowing dust removal device, but lack of systematic summary. This paper summarizes the research results of subway vehicle blowing and dust removal devices in recent decades, analyzes and compares the advantages and shortcomings of various dust removal devices, and provides an outlook on their future development and research directions.

“…The first two are constrained by the limitations of the environment or building conditions, so the smoke exhaust effect is bad [23]. Air curtain smoke control technology easily negatively affects the evacuation of people in underground confined spaces [24][25][26][27][28][29]. Water mist smoke reduction technology exhibits low smoke capture efficiency, leading to elevated CO concentrations within the evacuation channel and reduced smoke height.…”

Keywordsfoam smoke reduction fire smoke control underground confined spaces risk management Smoke control technology is crucial in the risk management of fire in underground confined spaces. In this study, the integrated foam smoke reduction device (FS-RD) of "foaming-spraying" is proposed in response to the challenging problem of smoke control of fire in underground confined spaces. The overall structure of FSRD device is designed and optimized through the numerical simulation of the internal flow field and experimental research. The optimal basic parameters are as follows: area ratio (R m ) of 20.25, pitch-to-diameter ratio (R td ) of 1/3 or 5/9, and throat diameter (d 3 ) of 18 mm . Additionally, the throat-nozzle distance (L t ) is 12 mm, and the operating pressure (p 0 ) is 3.0 MPa. Finally, the smoke reduction experiment verified that the FSRD designed in this study had a better effect of elimination than fine water mist and cylindrical foam jet, with the elimination efficiency reaching 36.73%. This study provides a new device for smoke reduction in controlling fires in underground confined spaces.
