PHASE SEPARATOR FOR TWO-PHASE MIXTURE IN ANNULAR FLOWS

摘要

96/83 In many fields of use, such as, for example, in steam turbine units, there is the requirement that liquid/ gas two-phase flows must be separated into their two phases. The phase separation already existing in an annular flow is here exploited for the final separation of a two-phase mixture. The annular flow (3) arriving at the inlet branch (1) of a water trap (2) flows through a twin pipe (5,7). whilst the gas core flow (4) is passed through an inner pipe (5) and then deflected sideways above the water trap (2), the liquid wall film (6) can flow down between the circular ring passage (12) formed by the inner pipe (5) and outer pipe (7).
