Abstract

The purposes of this research are to know the optimal gab and electric pressure (voltage) of electrode-plates coated with activated carbon and also to study their arrangement through dust removal efficiency. From the experimental results of attached dust mass at different electrode-plate gab, the frequency of attachment and detachment of dust was more increased as electrode-plate gab was closer. In attached dust mass per unit area of electrode-plate, the farther electrode gab, the more increased. But in total attached dust mass, the closer electrode gab, the more removed. From the experimental results, the optimal electrode arrangement in dust removal chamber was considered that the forward parts of chamber need to be increased the number of electrode-plate, the backward parts to be increased them. The dust attachment have no relation with electric pressure while showing high removal efficiency under condition of 5 kV of voltage and 2 cm of electrode-plates gab.

본 연구의 목적은 분진제거를 목적으로 제작된 활성탄 전극의 적정 간격 및 적정 전압 그리고 분진 제거효율을 통하여 전극의 적정한 배열에 대하여 알아보고자 수행하였다. 여러 전극 간격 별로 수행한 실험결과로부터 분진의 부착 및 탈착의 빈도수는 전극의 간격이 가까워질수록 증가하였다. 전극 단위면적 당 분진 부착량은 전극간격이 멀어질수록 증가하였지만 총 부착량에 있어서는 전극간격이 가까울수록 전극의 설치수가 많아져서 증가하였다. 이와같은 실험결과로부터 분진제거 챔버에서 전극의 설치간격은 앞단의 경우는 분진 부하량이 높기 때문에 제거량이 많도록 전극의 간격을 멀리하고 후단은 제거효율을 높이기 위하여 전극간격을 가깝게 설치하는 것이 바람직하다고 사료되었다. 그리고 전압 5 kV, 전극간격 2 cm에서 전압의 변화에 따른 분진부착량 실험결과에서 전압의 변화와 부착량과는 상관관계가 없었다.
