Abstract

PURPOSE:To provide a gas/liquid two phase fluid distributor capable of arbitrarily setting the distribution ratio of liquid phase upon distribution of gas/liquid two phase fluid by controlling the flow rate of the liquid phase fluid effluent from each outlet tube by changing the area of a fluid outlet hole communicating with each outlet tube. CONSTITUTION:Gas/liquid two phase fluid 10 entering a cylindrical container 1 from an inflow tube 2 is separated by the influence of gravity in an annular part space between a cylindrical container 1 inner wall located above a partition plate 5 and a cylinder 4 outer wall and stored at the lower part of the annular part space to form a fluid surface. The fluid passes through a fluid outlet hole 6 provided through the partition plate 5 and flows out into outlet holes tubes 3a, 3b. Thereupon, each fluid outlet holes 6 have the same diameter and the partition plate 5 is disposed to be horizontal to permit a head difference between the fluid surface and each fluid outlet hole 6 to be equal, so that the fluid flow rate passing through the fluid outlet holes are all equal. Accordingly, provided the shape of a dividing plate 7 is changed to change the number of the fluid outlet holes 6 communicating with the outlet tubes 3a, 3b, a distribution ratio of the liquid phase can be set to provide a gas/liquid two- phase fluid distributor capable of arbitrarily setting the distribution ratio.

Gas-liquid two-phase fluid Ql flowing into the cylindrical container (1) from the inflow pipe (2) (gas phase part (10a) and liquid phase part (1ob))
is separated by the influence of gravity within the annular space between the inner peripheral wall of the cylindrical container + 1) above the partition plate (5) and the outer wall of the cylindrical body (4).

A reservoir liquid level is formed at the bottom of this annular space.

This liquid flows out into the outflow pipes (3a) and (3b) through a liquid outflow hole (6) formed in the partition plate (5). At this time.

Each liquid outflow hole (6) has the same diameter, and the partition plate (5) is arranged horizontally so that the liquid level and each liquid outflow hole (6) are the same.
