Summary: | The present invention relates to a method for measuring fine dust by installing an impactor. According to the present invention, an inflow pipe channel is installed, through which a fluid is transferred, and which includes an inlet at one end part thereof to receive fine dust, wherein a dust flow path is formed at the other end part of the inflow pipe channel, and a light measuring module radiates light to the fine dust transferred to the dust flow path in order to measure scattered light from the fine dust. An impactor (112) is installed in the inlet (3) for filtering dust, and is installed by connecting two impactors of impactor 1 (112-1) and impactor 2 (112-2) in order to filter even fine dust particles. Therefore, the method for measuring fine dust can measure light scattered from fine dust and can conduct continuous sampling of the fine dust, thereby enabling performance verification, supplementation, and correction of a fine dust measuring device by using a light scattering method. In particular, the method for measuring fine dust can measure even particles of fine dust by connecting and installing two impactors, and can measure the fine dust by size selectively, conveniently and rapidly.
본발명은 임펙터가 설치되는 미세먼지 측정방법에 관한 것으로, 내부에 유체가 이송되고 한쪽 끝부분에 미세먼지를 유입시키는 인렛이 구비되는 유입관로가 설치되고,상기 유입관로의 다른쪽 끝부분에는 먼지유로가 형성되고 상기 먼지유로로 이송되는 미세먼지에 광측정모듈에 의해 광을 조사하여 미세먼지에서 산란하는 광을 측정하되,상기 인렛(3)에는 먼지를 걸러내는 임펙터(112)가 설치되되, 상기 임펙터(112)는 1임펙터(112-1)와 2임펙터(112-2) 두 개를 연결하여 설치하여 미세먼지입자까지 걸러내는 것으로,본 발명에 의하면, 미세먼지에서 산란하는 광을 측정함과 아울러 미세먼지를 연속으로 샘플링하는 것이 가능하므로 광산란법을 이용한 미세먼지 측정장치의 성능 검증이나 보완, 수정 등이 가능하다.특히 임펙터가 두 개가 연결 설치되어 미세먼지입자까지 측정할 수 있으며 미세먼지를 크기별로 선택적으로 간편하고 신속하게 측정할 수 있는 현저한 효과가 있다. |
