Abstract
(EN)
A compact multi-stage oil-water separator which has application in removing oily contaminants from bilge water in ships is disclosed. The oil-water separator has two toroidal mechanical separation stages (51, 88) on the suction side of a feed pump (27), and a cyclone separation stage (95) and a filtration stage (118, 140) on the output side of the pump. The cyclone separation and filtration stages are located inside the mechanical separation stages for compactness. The oil-water separator has built-in fail-safe operation to prevent the accidental discharge of water in the case of contaminated sensors.

Séparateur eau-huile compact multi-étagé, permettant d'enlever des agents contaminants oléagineux de l'eau de cale des bateaux. Ce séparateur eau-huile comprend deux étages de séparation mécaniques toroïdaux (51, 88), se trouvant du côté d'aspiration d'une pompe d'alimentation (27), et un étage de séparation à cyclone (95) ainsi qu'un étage de filtration (118, 140) situés du côté d'évacuation de la pompe. Les étages de séparation à cyclone et de filtration sont situés à l'intérieur des étages de séparation mécaniques afin de réduire l'encombrement de l'appareil. Ce séparateur eau-huile présente un fonctionnement à système de sécurité intégré afin de prévenir toute évacuation accidentelle de l'eau dans l'éventualité d'une contamination des capteurs.
