Abstract

It is about how much fine dust can be efficiently removed with respect to the electric dust collector used in factories and large facilities. The results of evaluating the fine dust removal efficiency are as follows. At 10,000 V, Efficiency method I showed 68.1 %, and Efficiency method II was 58.6 %, which was lower than that of Efficiency method I. At 5,000 V, Efficiency method I showed 57.6%, and Efficiency method II showed 51.6%, which was lower than Efficiency method I. At 2,500 V, Efficiency method I showed 50.3%, and Efficiency method II showed 24.4%, which was lower than Efficiency method I. In case of Efficiency method I, it is the efficiency calculated by using the dust concentration before and after passing through the filter. Efficiency method II calculated Efficiency method II to measure the efficiency a little more accurately in the environment where the air after the filter and the polluted air are mixed. Efficiency method II showed lower efficiency than Efficiency method I. As a result of the electrostatic precipitator test, the dust collecting performance was highest at 10,000 V, followed by 5,000 V and 2,500 V in that order.

본 연구에서는 공장 및 대형 시설에서 사용되고 있는 전기집진장치에 대하여 미세분진이 효율적으로 얼마나 제거 될 수 있는지에 대한 내용이다. 미세분진 제거 효율을 평가한 결과는 다음과 같다. 10,000 V 에서는 Efficiency method I은 68.1 % 를 보였고, Efficiency method I는 58.6 %로 Efficiency method I의 효율 보다 낮은 효율을 보였다. 5,000 V 에서는 Efficiency method I은 57.6 %를 보였고, Efficiency method II는 51.6 %로 Efficiency method I보다 낮은 효율을 보였다. 2,500 V 에서는 Efficiency method I은 50.3 %를 보였고, Efficiency method II는 24.4 %로 Efficiency method I보다 낮은 효율을 보였다. Efficiency method I의 경우 전 분진농도와 필터 통과 후 분진농도을 활용하여 계산한 효율이다. Efficiency method II는 필터 후의 공기와 오염된 공기가 혼합되는 환경에서 조금 더 정확한 효율을 측정하기 위해 Efficiency method II를 계산하였다. Efficiency method II는 Efficiency method I보다 낮은 효율을 나타내었다. 전기집진장치 실험 결과 10,000 V에서 집진 성능이 가장 높게 나타났으며, 그 다음 5,000 V, 2,500 V의 순을 보였다.
