A filter that can remove the fine dust according to the change of the environment of the subway station after installation of the platform screen door, along with satisfying the demand for improving the social air quality of the pollution such as fine dust, automobile soot, and odor of the subway station and the tunnel used by many citizens. Dust collector, EP) to provide a pleasant subway station environment.
In order to improve the performance of the electrostatic dust collecting part and the dust collecting part in this study, various experiments (several times) were conducted and the experiment was conducted. The shapes of the charging part and the dust collecting part are designed to be utilized as data for improving indoor air quality in the underground station. And the effect of dust collection efficiency and power consumption according to the shape of charging part and dust collecting part is verified through indoor experiment and field application evaluation.
As a result, it was found that the efficiency of PM10 reduction of PM10 and PM2.5 concentration was 87%, ventilation room 90%, PM2.5, 85% of the ventilation chamber, and 81% of the ventilation chamber (B), indicating that the fine dust concentration is greatly reduced. It was found that the air purifying ability of the electrostatic precipitator had an excellent effect for removing fine dust (PM10, PM2.5), and also had a reduction effect of about 20% in the case of the platform.
