초록

본 연구에서는 폐암을 유발하는 발암물질이며 다양한 문제의 원인이 되고 있는 유해물질인 미세먼지 제거특성을 조사하였다. 변수로는 습도, 초기미세먼지 주입량, 유속을 고려하였다. 실험결과 습도가 높은 경우 제거에 소요되는 시간동안 평균 농도는 낮아지지만, 최종농도에는 큰 차이가 없었다. 세 가지 초기미세먼지주입량의 변화는 모두 비슷한 제거경향을 나타내었다. 또한 유속이 0.6 m/s에서 0.3 m/s로 변할 경우 제거소요시간이 약 1.4배 증가하는 결과가 관찰되었다. 본 연구에서는 습도, 미세먼지 주입량, 유속 중 미세먼지 제거에 가장 큰 변화를 보이는 것은 유속으로 관찰되었다.

In this study, we examined the removal characteristics of suspended particulate matters which are one of carcinogens to cause lung cancer. The fine dust capture by a pilot scale filtration system depends on several important variables such as humidity, initial fine dust injection volume, and flow rate. The average concentration of particulate matters in the test chamber decreased, but the ultimate collection efficiency did not change during the filtration under high humidity, compared to those of using ambient conditions The initial injection amount of fine dust did not influence the particle capturing efficiency. When the flow rate reduced from 0.6 m/s to 0.3 m/s, the dust collection time increased approximately 1.4 times. Among all variables tested, the flow rate showed the most significant effect on the removal efficiency of fine particulate matter.
