Definitions

  • the invention relates to a water separation system for Separate water from a water-steam mixture with at least an inlet pipe arranged on the circumference of a container and provided with one above the inlet pipe Outlet pipe for steam.
  • water / water / steam mixture flowing into the water separator is in a container as a result of a combination separated from the effects of gravity and centrifugal force.
  • the water is separated from the container walls and flows down while the steam due to the inclination of the inlet pipes first led down and then on a flow reversal in the separator in the upper area of the tank is subtracted.
  • a water separation system is known from FR-A-961 953, with a container on the inlet side Disconnecting device for a partial steam flow upstream is.
  • the invention has for its object a water separation system with a particularly high separation quality.
  • This task is the beginning of a water separation system mentioned type according to the invention solved in that the Container on the inlet side to separate a partial steam flow a pipe bend is upstream, one of which Steam partial flow line branches.
  • the invention is based on the consideration of an existing one Fluid separator through a pre-separation to relieve a partial steam flow.
  • this upstream of the container of the water separation system and arranged parallel to this separator is using the pressure differential across the tank of the water separation system before the actual one Water separator steam is withdrawn from the water separator outflowing steam can be added.
  • the centrifugal force effect in the pipe bend is used, whereby in Area of water-steam stratification in the pipe bend a subset of the steam is drawn off.
  • each inlet pipe on the circumference of the container at an angle of inclination and / or arranged tangentially.
  • the inflow to the upstream separation device can done from above or from below. Therefore, the pipe bend the separator curved up or down his. Especially in the case of an inflow from below a drainage of the upstream separation device for Container of the water separator may be provided. To do this the steam partial flow line connected a drainage line and / or a drainage vessel in the partial steam flow line be switched.
  • the upstream is the end of the pipe bend
  • Steam partial flow line expediently branches while in the case of a downwardly curved pipe bend, the one facing it End of the steam flow line preferably siphon-like is trained.
  • connection of the steam lines from the water separator tank and the disconnecting device upstream of this can be directly behind the water separator or in one higher-level collection system.
  • the outlet pipe and the steam partial flow line are then with one another or with connected to the common collection system.
  • the advantages achieved with the invention are in particular in that due to one on the inflow side of the separator separated and run parallel to this Partial steam flow the pressure loss in the water separation system decreased. As a result of the resulting reduced The steam flow to the actual separator is reduced Vapor speed in the separator, so that an entrainment of Drops of water in the separated steam flow is avoided.
  • the formation of the separation device in the form of a pipe bend with connected steam partial flow line in addition, particularly small dimensions and small wall thicknesses the actual separator. This in turn leads to a particularly low total pressure drop in the water separation system and due to the small wall thicknesses to one particularly favorable behavior with temperature changes.
  • the water separation system 1 comprises a closed one Container 2 with an obliquely arranged Inlet tube 4 and an axially extending Outlet pipe 6 and also an axial water drain 8.
  • a closed one Container 2 with an obliquely arranged Inlet tube 4 and an axially extending Outlet pipe 6 and also an axial water drain 8.
  • the axial outlet pipe 6 instead of the axial outlet pipe 6, several, e.g. extractor pipes running at an angle or radially his.
  • the inlet pipe 4 goes into an upwardly curved one Elbow 10 over, together with one in the bend area steam partial flow line 12 connected to the container 2 upstream and parallel to this Separating device 14 forms.
  • the steam partial flow line 12 is connected to the outlet pipe 6, which is in a vapor collection system 16 opens.
  • a water / water / steam mixture flows G over the pipe bend 10 of the inlet pipe 4 into the container 2.
  • the inflow of the pipe bend 10 takes place from above.
  • a partial steam flow D upstream of the container 2 Elbow 10 and the partial steam flow line 12 is withdrawn and fed to the steam system 16 behind the container 2.
  • the centrifugal effect in the pipe bend 10 is used, in which Area of a water-steam stratification formed in the pipe bend 10 a subset of steam separated per unit of time becomes.
  • the steam partial flow D arises accordingly Pressure conditions in the water separation system 1, i.e. in the container 2 and in the parallel or steam partial flow line 12, on.
  • the container 2 is shown with two inlet pipes 4. While the one shown on the right side of the figure Elbow 10 is curved upwards, is on the tube bend 10 'shown on the left side of the figure is curved downward. Branched into the end facing the pipe bend 10 Partial steam flow line 12 is a drainage vessel 22 switched, which via a drainage line 23 with the lower region of the container 2 is connected. The drainage of the downward curved pipe bend 10 'takes place over a siphon 24 which is part of the steam partial flow line 12 '. The siphon 24 is also via a drainage line 25 connected to the lower area of the container 2. The Siphon-like configuration of the pipe bend 10 ' The end of the partial steam flow line 12 'is in FIG. 3 shown.
  • the partial steam flow lines 12, 12 ' are to the outlet pipe 6 connected. As dashed on the left side of Figure 2 shown, the steam partial flow line 12 'can also be connected directly to the steam collection system 16. To the Influence pressure loss in the steam partial flow line 12 ', a throttle or a valve 26 is connected in this.
  • Inlet pipes 4 with any combination from the top and downwardly curved pipe bends 10, 10 'may be provided can, the number of inlet pipes 4 should be limited to a few be because with an increasing number of inlet pipes 4 the Run-out ratios of that represented by curve 20 Beam is disturbed.
