Separator for nonmiscible liquids

摘要

A cylindrical main body (9) has a vertical central tube (11) attached to a horizontal grill (12) at the base and vertical tubes (16) running in the annular volume, extending down to a level (h) above the grill. The fluid to be treated enters through the central tube and is removed via the tops of the vertical tubes. The separated lighter phase is taken from the top of the annular volume (25). An inlet head is mounted at the top of the body, connected to the tops of a number of vertical tubes positioned around the central tube. The means of supplying the fluid to be treated include a pump (4) taking the fluid from a vessel or storage tank (1). The tops of the vertical tubes are connected via the inlet head to a recycling tube (21) returning to the vessel or storage tank. The top of the annular volume is connected to an annexe compartment (18) at the top of the separator, from which an extraction line (19, 20) runs. The device includes means of air purge at the top of the annexe compartment or the extraction line. The means of supplying the fluid to be treated include a strainer blower (6) floating on the surface of the fluid to be treated inside the vessel or storage tank. This blower has a collector connected to the inlet pipe.
