  • Oil removal from steel plate surface using microbubble flow

抄録

<p>An experimental study was conducted on the removal of oil film from steel plate surfaces by water containing microbubbles. As experimental conditions, the time for washing steel plates was varied, and the effect of the time on the removal effect was investigated. The effect of water temperature was also investigated. Experiments were also conducted with millimeter sized bubbles for comparison. To quantitatively measure the effect of oil film removal, a fluorescence method was used. A fluorescent agent was mixed with the oil, and the change in fluorescence intensity before and after the experiment was measured. Oil removal rate was evaluated from the fluorescence data. As the result, it was confirmed that the longer the immersion time, the more effective the removal under all conditions. In the bubble condition, microbubbles alone did not show a high cleaning effect, and millimeter size bubbles were more effective. As for the water temperature, higher temperature conditions were confirmed to be more effective in cleaning.</p>
