Definitions

  • the invention relates to a water separator for separating water from a water-steam mixture according to the preamble of claim 1.
  • a water-steam separation device In the evaporation system of a once-through steam generator, a water-steam separation device is usually used in the flow direction of a water-steam circuit behind the evaporator heating surfaces, which, in particular during start-up, divides the water-steam mixture arriving there into a water flow and a steam flow.
  • a separation device is known from EP-A-0 090 264.
  • the invention has for its object to design a water separator such that water can be separated from it in a water-steam mixture, which is free of steam, and that the remaining wet steam undisturbed, for. B. can flow into subsequent heating surfaces.
  • the inlet pipes open tangentially
  • the central axes of the inlet pipes intersect at a point lying on the vertical axis of the container, so that the water is guided into the lower part of the separating container due to the impact of the mixture flows.
  • the angle of inclination between the central axis of each inlet tube and the vertical axis of the container is between 15 ° and 60 °, preferably 45 ° to 55 °.
  • the number of inlet pipes can vary depending on the size of the separator, the inlet pipes being expediently arranged symmetrically in each case. Due to the inclined arrangement of the inlet pipes, a water-steam mixture flow entering the water separator is initially directed downward. The water is preferably collected in the lower part of the separator tank, while the steam together with the water not discharged downward flows upwards after deflection in the axial direction and is discharged there via the outflow opening.
  • a number of outlet pipes corresponding to the number of inlet pipes is provided as the outflow opening, which is offset in relation to the inlet pipes and distributed around the circumference and arranged radially.
  • internals for guiding the mixture flow downwards and deflecting the wet steam upwards are provided within the tank.
  • the internals are designed in such a way that surface parts lying above the mouths of the inlet pipes and the center are covered in segments, so that the water-steam mixture flow is forced to be deflected.
  • the internals can be above one and / or extend the area lying below the mouths of the inlet pipes.
  • the internals advantageously comprise cover plates running at least approximately at right angles to the axis of the container and guide walls arranged parallel to the axis of the container.
  • the water separator 1 according to FIG. 1 comprises a closed container 2 with inlet pipes 4 arranged obliquely and outlet pipes 6 arranged radially running, as well as a coaxial water outlet 8. Instead of the outlet pipes 6, a central exhaust pipe can also be provided.
  • the angle of inclination a between the vertical axis A of the container 2 and the central axis M of each inlet pipe 4 is between 15 ° and 60 °, z. B. 45 ° according to this embodiment.
  • the extensions of the central axes M of the inlet pipes 4 intersect at a point P, which lies on the vertical axis A of the container 2.
  • FIG. 2 shows, four inlet pipes 4 and four outlet pipes 6 are evenly distributed around the circumference of the container 2 and arranged offset from one another. Both the inlet pipes 4 and the outlet pipes 6 face each other in pairs.
  • a tube 12 is installed in the central region of the container 2, which carries a star-shaped or segment-like cover 14 extending to the container wall at the lower end and extends to the container lid 16, so that before the outlet pipes 6 are built-in segments 18 are formed.
  • a water-steam mixture flows into the container 2 in the direction of the arrows 20 via the inclined inlet pipes 4. After the collision of the mixture flows in the area of point P, wet steam deflected upwards flows through the segments 18 and over the outlet pipes 6, while water falling down flows out via the water outlet 8.
  • the internals in turn comprise a central tube 12 'and cover plates 14' running at right angles to the axis A of the container 2, which are connected to guide walls 22 running parallel to the axis A.
  • the guide walls 22 form segment-like guide spaces and delimit entry areas 24a and exit areas 24b in the container interior.
  • the water-steam mixture entering the container 2 via the inlet pipes 4 is first guided in the direction of arrow 25 into a settling chamber 26 and segregates into water and wet steam.
  • the wet steam is deflected by 180 ° and in Direction of the arrow 27 through an outflow chamber 28 located above the internals 12 ', 14', 22 and via the outlet pipes 6 in the direction of the arrows 30 to downstream heating surfaces (not shown).
  • water separated from the water-steam mixture, which is free of steam, is discharged via the water outlet 8.
