초록
본 연구에서는 습식사이클론에 의한 망간단괴와 해수 분리의 타당성을 검토하였다. 이를 위해 소형의 습식사이클론을 사용하여 입도가 조절된 망간단괴의 분리실험을 행하였으며 분리곡선을 작성하여 분리효율과 희석률(dilution ratio)을 계산하였다. 평가결과 분리입도 은 20㎛이였으며 이 때의 분리효율(imperfection)은 0.125이었다. 이때 습식사이클론을 이용하여 고-액 2상류를 분리할 경우, 하향흐름(underflow)의 광액농도는 약 86.8wt%(희석률 0.15)로 습식사이클론을 양광시스템의 분리장치로 사용하는 것이 가능하다고 판단되었다.
Abstract
In this study, application of hydrocylone for dewatering system of manganese nodules lifted with sea water was examined. For this, separation of size controlled manganese nodule was conducted using a small hydrocyclone. Performance curve and dilution ratio were obtained from the experimental results. The cut point, , and imperfection, I, were about 20㎛ and 0.125 respectively. Pulp density of underflow was 86.8 wt.% and dilution ratio of underflow was 0.15 in case of the hydraulic lifting system for manganese nodules. From the results, it was considered that a hydrocyclone can be applied to the hydraulic lifting system for dewatering manganese nodules.
