본 논문은 흡착형 활성탄소섬유필터(Activate Carbon Filter, ACF)를 국산화하기 위하여 수입 필터와 유사한 원통형을 설계하고, 휘발성유기화합물(Volatile Organic Compounds, VOCs) 탈착용 스팀 공급에 따른 스팀 유동 특성 분석 및 성능을 평가한다. 필터 크기는 수입 ACF 크기를 고려하여 외경 600 mm, 내경 400 mm, 높이 1500 mm 형상으로 설계하고, 스팀이 흡착 필터 전체에 고르게 동작하도록 형상 도출을 위해 필터 상부 크기, 두께, 높이를 고정한 상태에서 하부 필터 내경 크기를 감소시켜 가면서시뮬레이션한다. 스팀 공급량은 350 kg/hr을 1시간에 6회 공급하는 기준을 적용하고, 활성탄소섬유의 흡착은 농도 변화에 따른 총흡착량과 파과점에서의 흡착용량 차이를 평가한다. 흡착특성은 흡착반응기에 활성탄소섬유를 거치시킨 후 시험가스 공급유량100L/min과 VOCs 농도 400ppm 공급 조건에서 흡착제 충진 높이를 3~75 mm 범위로 조절하여 공간속도(10,000~254,000–h)조건에서 활성탄소섬유 흡착 특성을 확인한다.
Abstract
We have implemented the adsorption-type ACF(Activated Carbon Filter) of a cylindrical shape, and evaluated theperformance according to the supply of steam for VOCs(Volatile Organic Compounds) desorption. The filter size isdesigned to have an outer diameter of 600mm, an inner diameter of 400mm, and a height of 1500mm, and it issimulated by reducing the inner diameter of the lower filter while fixing the upper size, thickness, and height ofthe filter to make steam evenly throughout the adsorption filter. The steam supply applies the standard forsupplying 350 kg/hr six times an hour, and the adsorption of activated carbon fibers evaluates the differencebetween the total adsorption amount according to the concentration change and the adsorption capacity at thefruit point. The adsorption characteristic is to confirm the adsorption characteristic of the activated carbon fiberunder spatial speed (10,000-254,000-h) by adjusting the adsorbent filling height to a range of 3 to 75 mm underthe supply conditions of 100L/min of test gas supply and 400ppm of VOCs concentration.
