METHOD OF REMOVING OIL PRODUCTS FROM WATER SURFACE Russian patent published in 2022 - IPC E02B15/04 

FIELD: ecology; technological processes.

SUBSTANCE: invention relates to cleaning of water surface from liquid contaminants, mainly from oil products. Method of oil products removal from water surface includes creation of rotation movement of water in volume of hollow cylinder located below water-oil product interface with formation of vortex funnel in it and pumping of oil products from it. Creation of rotational movement of water is provided by rotation of the hollow cylinder, the end of the receiving branch pipe of the oil product pumping device is placed coaxially inside the hollow cylinder below its upper end by the value H/2, thickness of oil product layer on water surface, density and kinematic viscosity of water and removed oil products are measured. Measured values are used to set the immersion depth h of the upper edge of the hollow cylinder from the water-oil product interface and the optimum angular frequency of rotation of the hollow cylinder ω, which are determined by mathematical relationships.

EFFECT: higher efficiency.
