ABSTRACT:
The invention relates to a high capacity oil recuperator for use in rough waters, associated with a fixed platform or to a de-polluting ship.
Said recuperator consists of a submerged assembly composed of a cylinder of vanes rotating inside a stator of which the configuration induces and maintains in the liquid mixture sucked in a localized vortex which is not associated with the flow and in which the oil concentrates immediately under the effect of a strong centrifugal acceleration. A pump working in connection with the stator sucks in the oil for storage purposes. The energy communicated to the rejected cleaned water can be advantageously used for propelling and maneuvering the ship or platform.
The invention finds an application in the production of skimming crafts of all capacity used for the de-pollution of rough waters, in harbors, rivers, estuaries, and at sea.
