<p>A separator device for removing pollutants from waste water, particularly oil from an oil-water emulsion, comprising a thermally insulated tank (1), containing the liquid (3) to be treated and closed by a conical cover member (15) acting as a condensing surface, said tank (1) being further provided with a gutter (17) on the inner surface for collecting the condensate. The device further comprises an external heating chamber (9) for heating and spraying back a portion of said liquid (3) into the upper portion of said tank (1) to form a rising mass of water vapor (13), and a unit heater (31) mounted on the top of said cover (15) for heating the surrounding environment. The cover incorporates a cooling coil (27) in which the coolant of said unit heater (31) is circulated, whereby a fraction of the energy expended for the separation process is used for heating the environment surrounding the device.</p> |
