Title:

FLOATING-OIL RECOVERY PROCESSING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2021/210192

Kind Code:

A1

Abstract:

[Problem] To provide a floating-oil recovery processing apparatus that is capable of increasing floating-oil recovery efficiency while suppressing the spread of oil, without directly coming into contact with the floating oil. [Solution] A floating-oil recovery processing apparatus that has a bubble-curtain generation mechanism and an ejector apparatus 40, and that recovers an oil-water mixed fluid in a state in which the floating-oil recovery ratio is high as a result of jetting high-speed water toward a floating oil layer via the ejector apparatus 40 while collecting the floating oil in a non-contact state by means of bubble curtains generated in water from aeration pipes 30.
