METHOD OF COLLECTING OIL SPILLED IN OPEN SEA AND COMPLEX OF DEVICES FOR IMPLEMENTATION THEREOF Russian patent published in 2022 - IPC E02B15/04 

FIELD: chemistry; environmental protection.

SUBSTANCE: invention relates to environmental protection, and structurally, to containment and collection of oil or oil products from water surface. Method for collecting oil spilled on the high seas by means of a set of devices for its implementation is as follows. First, boom 1 is installed in the form of a circle with boom 1 anchored at the sea bottom by means of a number of anchor assemblies. Boom 1 can be detached from tugs and closed in a ring on a new section. Then attachment 3 with propeller element and paddle blades is switched on, which inject one-way flow in direction of rigid line 6 and surface stream 5 of oil is formed, which along radially installed guides of rigid lines 6 due to the flow injected by the paddle element tends in the direction of rigid line 6 to centre 8 and collects oil in centre 8 at the inlet branch pipe 9 for collection of oil products. Rowing blades are made narrow so as to pump only the upper layer of water, which contains oil and not to touch deep layers, as it would be when using a standard paddle wheel. As a result, all oil is collected in centre 8 and the surface layer of oil collected in centre 8 increases many times compared to the initial one, when oil was spilled over the entire area. Further, the pumping equipment with the inlet branch pipe 9 for the collection of oil products is switched on, into which the liquid collected in centre 8 is supplied with an oil concentration of 50 % and higher, and through a pipeline running below the rigid line, it enters the vessels installed on ship 10.

EFFECT: invention makes it possible to ensure many times faster oil recovery than that of analogues, and besides, chemical elements are not used in the claimed group of inventions.
