FIELD: devices for oil product gathering from water surface. SUBSTANCE: device includes cylindrical-conical vacuum hydrocyclone connected with oil intake funnel. Installed coaxially along central axis of hydrocyclone are discharge branch pipe, fluid light and heavy phases branch pipes. Discharge branch pipe and fluid light phase branch pipe may have nozzles. During device operation, oil products from funnel are sucked into hydrocyclones. Fluid due to its tangential supply in hydrocyclone takes up rotary motion and under effect of centrifugal forces, fluid is separated by density. Fluid heavy phase is forced-out to hydrocyclone periphery and withdrawn through fluid heavy phase branch pipe. Oil product light phase will be rotated over hydrocyclone central axis and withdrawn from hydrocyclone through fluid light phase branch pipe. EFFECT: intensive gathering of oil products from water surface and efficient separation of fluid by density. 2 dwg
