초록

가정과 요식업 사업장에서 발생하는 미세먼지는 전체 미세먼지 배출량의 약 4%정도로 낮은 비율을 차지하고 있다. 하지만 요식업 사업장에서는 일시적 미세먼지 농도가 최대 60배 가까이 측정될 만큼 오염농도의 변화율이 매우 높다. 비산업 연소 사업장에서 발생하는 오염 물질은 입자상 미세먼지와 가스상 유기화합물로 구성되며, 이 오염물질을 제거하기 위해서 여러 집진원리 중 가스상 물질과 입자상 물질의 동시 제거에 효과적인 시스템인 세정집진을 적용하였다. 이는 이류체 분무 노즐을 이용한 가압수식 액체 분사 방법으로 브라운 운동의 확산 포집의 확률을 높인 방법이다. 제작된 미세먼지 제거 장치를 이용하여 노즐 분무 기압 조건과 각도 등에 따른 미세먼지 집진 시스템의 집진 효율성을 분석하였으며, 그 결과 미세먼지와 가스상 유기화합물 제거효율이 90% 이상을 만족하는 것을 확인하였다. 개발된 시스템은 기존 사업장 후드 시스템에 별도의 설치비용 없이 미세먼지 집진 제거가 가능하여 향후 높은 활용성이 기대된다.

The fine dust generated in the home and restaurant business occupies a low ratio of about 4% of the total fine dust emissions. However, at the foodservice business, the rate of change of the pollutant concentration is very high, so that the temporary fine dust concentration can be measured up to 60 times. The pollutants generated from non-industrial combustion plants consist of particulate fine dust and gaseous organic compounds. To remove these pollutants, cleaning dust collection system, which is an effective system for simultaneous removal of gaseous and particulate matter, is applied. This is a method of increasing the probability of diffusion capture of the Brownian motion by pressurized liquid injection method using the atomizing nozzle. The dust removal efficiency of the fine dust collecting system was analyzed by nozzle spraying air pressure condition and angle using the manufactured fine dust removing system. As a result, it was confirmed that the efficiency of removal of fine dust and gaseous organic compounds was more than 90%. The developed system is expected to be highly usable in the future because it can remove particulate dust from the existing plant hood system without any installation cost.
