초록

연속 조작 기포탑에서 부유물질의 첨가에 의한 기포의 분쇄효과를 압력변동의 특성을 분석함으로써 고찰하였다. 액체 및 기체의 유속, 분산판으로부터의 높이, 부유물질의 첨가량 등을 실험변수로 선택하였으며, 이들 실험변수의 변화에 따른 압력 변동의 평균값, 표준편차, 비대칭도, 첨도 그리고 스펙트럴 밀도 함수 등의 변화를 검토하였다. 본 연구의 결과 연속 조작 기포탑에 부유기포 분쇄물질의 첨가는 기포탑내에서 기포흐름의 균일성과 안전성을 향상시킬 수 있는 것으로 나타났다.

Effects of floating material on the bubble breaking were investigated by analyzing the pressure fluctuations in a bubble column operating continuously. The gas and liquid velocities, height from the distributor, and amount of floating material added in the column were selected as experimental variables. The variations of the mean value, standard deviation, skewness, kurtosis and spectral density function from the pressure fluctuations were determined with the variations of experimental variables. From the results of this study, the addition of floating material into the bubble column could improve the qualities of uniformity and stability of bubble flowing in the column.
