dc.description.abstract도시철도터널은 전동차 운행으로 바닥 먼지가 비산되거나 새로 발생된 마모 먼지로 오염되고 있다. 전동차가 운행하면서 이러한 부유 먼지를 제거하기 위해서 관성집진기인 배플과 전기집진기로 구성된 하이브리드형 집진장치를 개발하였다. 하이브리드형 집진장치의 유량과 집진효율은 서로 반비례하므로, 유량과 집진효율의 관계를파악하기 위해 2가지 배플 모델을 제작하여 성능을 평가하였다. 유속이 3.4 m/s인 A1 모델을 장착한 집진장치의0.5µm 이상인 입자의 집진효율은 30% 이상이었고, 유속이 4.7 m/s인 A2 모델의 경우 20% 이상이었다. 인가전압이 13 kV일 때 1시간 동안 A1 모델 집진장치의 PM10 집진량은 253 mg, A2 모델의 경우 242 mg으로 추정되었다.-
dc.description.abstractUrban railway tunnels are polluted by resuspension of deposited bottom dust or newly generated wear dust.A hybrid type dust collector consisting of a baffle and an electrostatic precipitator was developed to remove these typesof airborne dust when trains are running in the tunnel. Since dust collection efficiency of the hybrid dust collector isinversely proportional to the airflow rate, the relationship between airflow rate and dust collection efficiency was exper-imentally investigated for two baffle models. Collection efficiencies for dust larger than 0.5 µm for the hybrid dust col-lector model A1, operated at 3.4 m/s, were greater than 30%; those for the hybrid dust collector model A2, operated at4.7 m/s, were higher than 20%. When the applied voltage was 13 kV, the amounts of PM10 collected with model A1 andmodel A2 dust collectors were estimated at 253 µg and 242 µg per hour, respectively.-
