SEPARATORS FOR THREE-PHASE OR TWO-PHASE FLUID MIXTURES REALIZED WITH A CENTRIFUGAL DEVICE DESIGNED FOR THE SEPARATION OF THE GAS FROM THE LIQUID MIXTURE

摘要

The present invention refers to three or two phaseseparators provided with an inlet centrifugal device(40,70) for the preliminary separation of the gas phasefrom the fluid mixture; the centrifugal separationdevice includes a first stage (40',70') having acircular section delimited by a wall (42, 63) and b,y theexternal surface of the second stage plate and a secondstage (40",70"), internal and coaxial to the firststage, realized by a plate rolled as an 'Archimedean'spiral around the vertical axis common to the twostages of the centrifugal separation device, in orderto operate the separation of the gas phase from theliquids, obliging the flowing fluid to follow acircular path that brings the liquid and its dropletsto adhere to the wall surface (42,63) and to theinternal surface of the spiral (47), obtaining theirseparation from the mixture.
