초록

본 연구에서는 도로환경에 적용 가능한 통기성 정전필터를 개발하여 흡착능을 평가하였다. 흡착특성은 ASHRAE 52.1, 52.2 등의 방법으로 입경별 제거율과 압력별 흡착량 등을 평가하였다. 평가 입경범위는 $0.3{\mu}m{\sim}10.0{\mu}m$로 12단계로 제거율을 평가하였다. 필터는 $2.5{\mu}m$ 이상에서 91.3%의 제거율을 보였으며 그 미만의 범위에서는 입경에 따라 감소하여 평균 53.5%의 제거율을 보였다. ASHRAE Dust 합성 분진에 의한 중량 제거율은 초기압력 22.6 mmaq에서 말기압력 35 mmaq까지 측정된 결과, 96.7%였으며 이때까지 흡착량은 $715.9g/m^2$ 이었다. 압력에 따른 흡착형태는 Langmuir 선도를 보였다. 말기압력까지 흡착된 필터를 물세정으로 1, 2차 재생한 후 흡착을 평가한 결과 제거효율에는 차이가 없었으나 초기압력과 흡착량은 약간의 저하가 발생하였다.

In this study, a electrostatic filter which could be applicable to road environment was developed and evaluated in adsorption capacity. The evaluation were performance for removal by particle size and adsorption amount by pressure using ASERAE 52.1 and 52.2. The range of size for removal test was $0.3{\mu}m{\sim}10.0{\mu}m$ which had 12 steps. The filter showed 91.3% removal efficiency from $2.5{\mu}m$ and under the size, average 53.5% proportional to decreasing size value. The weight removal was 96.7% from 22.6 mmaq, initial pressure to 35 mmaq, end pressure with $715.9g/m^2$, the adsorption amount. The shape of isotherm was expressed as Langmuir's one. After washing saturated filter with dust to end pressure, the initial pressure and adsorption amount of the filter showed a light drop with no removal efficiency decline.
