초록

안개는 교통시스템에서 경제적 손실을 초래하고 대기오염물질과 결합하여 건강에 문제를 일으킨다. 안개 제거 시스템은 개발노력에도 불구하고 대부분 발생한 안개를 모니터링 후 제거하도록 구성되어 있으며, 지속적으로 시스템을 유지하기 위한 에너지 공급과 유지 보수가 필요하다. 본 연구에서는 이러한 안개제거 시스템의 한계를 극복하기 위하여 이끼필터(이끼를 결합한 폴리올레핀 그물망)를 응용하는 안개 제거 방법을 제시하였다. 서로 다른 표면구조를 가지는 3가지 이끼의 수분 흡수율을 측정하고 이끼구조와의 상관관계를 살펴보았다. 가장 작은 기공의 직경과 가장 큰 총 기공의 내부 표면적을 가지는 공작이끼가 높은 수분 흡수율을 가짐을 확인 후, 공작이끼로 안개 제거 필터를 만들어 안개제거 포집/제거에 사용되는 기존의 폴리올레핀 그물망과 성능을 비교하여 보았다. 본 논문에서 제시된 이끼필터를 이용한 안개 제거 시스템은 에너지 없이 지속적으로 안개를 제거할 수 있는 경제적이면서도 친환경적인 방법이다.

Fog causes economic losses in transportation. It also results in health problems when it is combined with air pollutants. Considerable research efforts have focused on developing fog removal systems. However, most systems operate themselves after monitoring the fog. Additionally, continuous energy supply and maintenance are required to retain the fog-removal efficiency of the system. This study included the demonstration of a moss filter (a polyolefin mesh interlaced with moss) as a fog-removal method overcoming the limitations of the fog removal system. Three types of mosses with different surface structures were investigated to elucidate the relation between the moisture absorption rate and the structures. Among the different moss types, Hypopterygium japinicum showed the highest efficiency based on the smallest pore diameter and the largest total pore area. The visibilities with the moss filter and the polyolefin mesh were compared to perform the fog removal tests. The moss filter could provide a cost-effective and eco-friendly fog removal system with sustainability.
