Abstract

Generally, there are three ways to remove VOCs from the small painting booth; adsorption, burn and oxidation catalyst. RTO and RCO are high efficiency methods for removing VOCs. But they require large installation areas, which are not suitable for the small painting booth. And we need a new removing method because it is difficult to predict the A/C changing time and the recycle time. To solve these problems, we have developed the Arc plasma system which is simple and enable consecutive-use. It removes VOCs effectively and eco-friendly. In this study we have investigated the enrichment material and VOCs removal efficiency.

VOCs는 인체에 치명적인 질환을 유발하는 물질로써 도장공정중 발생되는 양이 가장 큰 비중을 차지하고 있다. 일반적으로 소형 도장시설에서 발생되는 VOCs를 처리하는 방법으로 활성탄 흡착 또는 흡착 후 연소 및 촉매 산화법 등을 사용하고 있다. 하지만 활성탄 교체주기, 재생시설 및 재생주기 등을 예측하기 어려워 새로운 처리방법이 필요하다. 비이송식 플라즈마 시스템을 이용한 VOCs 제거방법은 일반 연소과정이 아닌 고전압 아크 방전에 의한 고온 플라즈마 유동 발생 기술을 이용한 제거방법으로 화학반응이나 오염이 없는 고순도의 고온 열처리 및 열분해가 가능하다. 본 연구에서는 고온 아크플라즈마 시스템을 이용하여 특수 환경오염물 및 VOCs 가스 열처리 공정의 핵심기술로 활용하여 작동가스 유량 변화에 따른 VOCs 처리 효율 및 플라즈마 전력량에 따른 처리 효율을 측정하였다. 또한 유해가스 처리효율성 증대를 위해 플라즈마 반응기를 최적화하여 제작하였으며 성능을 파악하였다.
