METHOD AND DEVICE FOR OIL PRODUCT GATHERING FROM WATER SURFACE Russian patent published in 2007 - IPC E02B15/04 

FIELD: environment protection, particularly to clean water surface of oil products.

SUBSTANCE: method involves collecting mixture of oil product with water under vacuum; separating the mixture and then supplying oil products in oil collector. The mixture is collected under water surface in cavitation mode, which is accomplished by air injection. During mixture separation directed jet of water mixed with dispersed air and oil products is provided. Method is realized with the use of device comprising oil-collecting funnel, ejector with outlet pipe, float and oil discharge pipe. Ejector is made as cavitating aerator with air supply pipe and discharge manifold. Oil-collecting funnel is located on float/floats and oriented in direction of stream exiting outlet manifold. The cavitating aerator may be provided with intermediate vessel arranged between discharge pipe and discharge manifold thereof. The float/floats may be controlled. Intermediate vessel has pressure regulator connected to controllable float/floats of the funnel.

EFFECT: increased efficiency and extended field of application due to possibility of device usage in cleaning structures.
