Abstract
A floating-oil recovery device includes: a bubble-curtain generation mechanism configured to discharge air into water to generate a bubble curtain in the water so as to increase a thickness of a film of floating oil while regulating spread of the floating oil; and an ejector configured to recover an oil-water mixed fluid having the floating oil and the water mixed with each other by jetting high-velocity water toward the film of floating oil enclosed with the bubble curtain to destroy the film of floating oil.
