Definitions

  • Fig. 1 shows the known pressure-enthalpy diagram for water / steam, in which some frequently occurring work areas A to E are shown.
  • X means the proportion of steam
  • X 0 for pure water
  • X 1 for pure steam.
  • the water-steam state moves roughly within area A and during a start after approximately eight hours of inactivity, this state runs approximately within area B, area C being common to A and B.
  • the water content in the mixture predominates and the pressure head losses in the pipes therefore predominate. This means that in areas A, B and C there is above all the risk of the flow stagnating through individual pipes.
  • DE-C-882 996 proposes arranging in the tubular container a partition wall which extends in the longitudinal direction and divides the container into two communicating chambers.
  • the dividing wall is flat, leaves the communicating connection for the liquid phase free between its lower edge and the container bottom and has tongue-like extensions on its upper edge, one of which projects into the supply lines opening into the container from above.
  • the discharge lines branch off in the upper area of the container on both sides of the partition.
  • the mixture supplied is divided into two partial streams and fed to the two chambers, from which it is then assigned to the respective chamber neten discharge lines.
  • a liquid level is formed in each sub-chamber which, despite the partition, is still subject to strong fluctuations in the inflowing mixture, which has an unfavorable effect on a uniform distribution of the phases in the discharge lines.
  • the invention is based on the features of the preamble of claim 1 from the known container with a partition according to DE-C-882 996. It is based on the task of further improving the phase distribution container of this type in such a way that the level in it is better kept constant under all circumstances, so that it works optimally with any gas-liquid mixing ratio and at the same time the design and manufacturing costs remain low.
  • the design of the partition as a U-shaped channel divides the container space into an inlet chamber and an outlet chamber, which communicate with one another not only on the liquid side but also on the gas side. In this way it is achieved that level fluctuations in the inlet chamber have only a weak weakening effect on the level in the outlet chamber.
  • the distribution of the two phases of the mixture flowing in the discharge lines is thereby more uniform than in the known containers with a flat partition and without a gas passage opening.
  • An additional advantage of the invention can be seen in the fact that it can be applied to already existing phase distribution containers by subsequently installing the U-shaped channel as a partition. Another advantage is the strengthening of the container by the channel when it is connected to the ends of the container.
  • a phase distributor container for an evaporator is known from US-A-2 220 595.
  • the container is cylindrical and is vertical.
  • a feed line for the two-phase mixture opens tangentially into the container in order to impose a rotational flow on the mixture in the container.
  • a coaxial cylindrical partition is arranged inside the container, which ends at a distance from the container bottom at its lower end and has window-like cutouts at its upper end connected to the container ceiling, which form gas passage openings.
  • several discharge lines for the mixture protrude from above, which dip into the liquid phase with their lower ends and which have axial longitudinal slots in their lower half through which the two-phase mixture can flow into the discharge lines.
  • a partition in the form of a U-shaped channel 15 is arranged in the interior of the phase distributor container 1 and extends along it and is welded to the two end plates 40.
  • the channel 15 divides the interior of the phase distributor container 1 into two chambers: an inlet chamber 2, which is surrounded by the channel 15, and an outlet chamber 3, which surrounds the channel 15.
  • two gas passage openings 11 are provided, via which the inlet chamber 2 and the outlet chamber 3 are connected. Both chambers are further connected by liquid passage openings 12, which are in the form of round holes in the horizontal part of the channel serving as the bottom of the inlet chamber 2.
  • Supply lines 20 run essentially vertically and open into the inlet chamber 2 after they have been bent slightly in the direction of the center of the circular cross section of the phase distributor container 1.
  • Discharge lines 30 likewise run essentially vertically, but are more bent than the feed lines 20 before they also open into the outlet chamber 3, also aimed at the center of the cross section of the phase distributor container 1.
  • the feed and discharge lines 20 and 30 run symmetrically to a vertical plane through the longitudinal axis of the phase distributor container 1, so that all the mouths of the feed lines and all of the mouths of the discharge lines each lie in the same height range.
  • the phase distributor container 1 functions as follows:
  • a mixture of a liquid and a gaseous phase flows through the feed lines 20 and is injected into the inlet chamber 2.
  • the deflection of the irradiated mixture and the different specific weights of the two phases separate them from one another in the inlet chamber 2, with a generally strong swirl prevailing in the inlet chamber 2.
  • the separated gaseous phase escapes through the narrow gas through openings 11 into the outlet chamber 3, as a result of which it flows to the discharge lines 30 in a largely calm manner.
  • the separated liquid phase in turn leaves the on Step chamber 2 through the liquid passage opening 12 and collects in the outlet chamber 3, the extremely limited connection to the inlet chamber 2 and the relatively large liquid mass in the outlet chamber 3 prevent the transmission of turbulence from the inlet chamber 2 to the outlet chamber 3.
  • a stable and uniformly distributed level 31 is thus established in the outlet chamber 3 between the two phases, and the gaseous phase flowing in each mouth to a discharge line 30 entrains a well-dosed amount of liquid.
  • the phase distributor container 1 only functions as a liquid separator.
  • the level 31 rises quickly and closes the mouths to the discharge lines 30 more and more:
  • the amount of gas to be discharged remains approximately constant, it flows faster and faster through the remaining cross-sections of the flow according to the known laws of continuity mentioned mouths, so that the static pressure is always lower and the amount of liquid sucked in is greater.
  • the phase distributor container 1 With a reasonable dimensioning of the various lines and components of the phase distributor container 1, this results in an operating state in which the amount drawn in is equal to the amount of liquid entering through the liquid passage openings 12 and the level 31 remains constant. If the proportion of liquid in the incoming mixture changes, the level 31 shifts and the proportion of liquid in the discharge lines 30 changes accordingly.
  • the actual function of the phase distributor container is fulfilled in all cases because - whether no liquid or pure liquid flows in the discharge lines 30 - the phase distribution is constant for a specific operating state and is the same for all discharge lines 30.
  • phase distributor container 1 according to the invention according to FIGS. 2 and 3 has proven itself better than the phase distributor container according to the prior art, because the steam entering when it passes through the Entry chamber 2 to the exit chamber 3 is very well distributed and has a uniform temperature in the exit chamber.
