Abstract

The current study evaluated the air quality of the smoking booth equipped with the air purification system consisting of photocatalysts and air filters by measuring the concentrations of hazardous substances of tobacco smoke such as CO, HCHO, $CH_3CHO$, PM10 and PM2.5. To enhance the removal efficiency of hazardous substances, an infrared ray was exposed to improve the reactivity of OH radical generated from the photocatalyst toward environmental tobacco smoke (ETS) gas phase hazardous materials. It was found that the smoking booth with the air purification system improved the removal efficiency of hazardous substances containing formaldehyde by 85.2% compared to that of the smoking booth without any purification systems. In addition, the removal efficiency of the fine dust after treatment was enhanced up to 89.4%.

본 연구에서는 CO, HCHO, $CH_3CHO$, PM10, PM2.5 등의 담배연기 내에 포함된 유해물질들의 농도를 지표로 광촉매와 필터로 구성된 공기정화장치를 부착한 흡연부스 내의 공기질을 평가하였다. 또한 광촉매에서 발생되는 OH 라디칼과 담배연기 내 가스상 유해물질들과의 반응성을 향상시켜 제거효율을 높이기 위해 적외선을 주사하였다. 공기정화장치와 필터를 활용한 흡연부스의 실험 결과, 시스템 가동 전보다 가스상 오염물질은 포름알데히드 포함 최대 85.2% 향상된 제거효율을 나타냈다. 처리 후의 미세먼지는 최대 89.4% 향상된 제거효율을 나타냈다.
