Abstract
높은 열 회수특성으로 인해 낮은 농도의 VOC를 소각처리 시키는데 매우 유용한 장치로 알려진 축열 촉매소각장치를 제작하고 특성실험을 수행하였다. 톨루엔의 농도가 150 ppm 이상인 모사 VOC 경우 보조 열을 공급하지 않아도 시스템을 안정적으로 운전할 수 있음을 확인하였고, 밸브가 전환될 때 미반응 톨루엔이 배출되지만 95% 정도의 높은 VOC 소각 처리 효율을 얻을 수 있었다. 축열 촉매소각장치의 운전에서 VOC의 처리효율은 유체의 흐름을 바꾸어주는 밸브의 전환주기, VOC 농도, 축열재의 양 등에 의해 결정되는데, 이들의 영향을 분석하였다.
Regenerative catalytic oxidizer(RCO) having high recovering efficiency of energy enables catalytic purification of polluted air containing a low content of volatile organic compounds(VOCs). From experimental study of the regenerative catalytic oxidizer, the VOC toluene concentration higher than 150 ppm can be handled without introduction of additional energy. The removal efficiency of VOC from the polluted air is around 95%. The influence of several operating parameters including cycle period, concentration of the VOC and mass of inert material(cordierite honeycomb) on the removal efficiency has also been examined.
