Definitions

  • the invention relates to a device for Separation of water and steam from a water-steam mixture with two in of different heights arranged horizontally and over one Connecting pipe interconnected collectors, where in addition to the connecting pipe, the first one below Collector an inlet pipe for the water-steam mixture and a water outlet pipe for the separated water and the second collector above it a steam outlet pipe for the separated steam.
  • Such e.g. Device known from the German patent DE-C-859 736 is usually used in the evaporation system a steam generator used. At the Start-up or load change operation of such a steam generator generally fall in the evaporation system large amounts of water. The water is usually in one with respect to the flow direction of a water-steam cycle behind the evaporator heating surfaces of the Evaporation system provided water-steam drum deposited. Because such a water-steam drum due to the high vapor pressure prevailing there and the large inner diameter has a large wall thickness, is the permissible temperature change rate in Start-up and load change operations are severely limited.
  • the invention is therefore based on the object Particularly simple device for water-steam separation specify which is sufficient even with large temperature changes is heat elastic.
  • the device according to the invention works on the principle of gravity separation, whereby by Arrangement of the two collectors at different heights in a particularly good water-steam separation is achieved.
  • At least four inlet pipes for the water-steam mixture in one Group summarized.
  • For a sufficient length of stay of the water-steam mixture within the separation device To ensure the distance is expedient of the inlet pipes within a group smaller than the distance of each inlet pipe from the one connecting the collectors Connecting pipe.
  • this or each Inlet pipe one above the confluence with the first collector lying axis bent.
  • a return pipe can be provided one end of which is in the lower part of the second collector is connected to this, and the other end the water outlet pipe of the first lower collector is connected is.
  • a third below the first collector Collector can be arranged horizontally in the water outlet pipe of the first collector.
  • the second and third collectors together via a pipe be connected.
  • the steam outlet pipes of the second collector can also be combined in groups, each group comprising at least two, preferably four, steam outlet pipes. This ensures that no water is carried along with the steam emerging from the second collector, which acts as a distributor, and the steam accumulating in the second collector can be distributed in a suitable manner to subsequent heating surface systems.
  • FIG. 1 shows Cross section and Figure 2 in longitudinal section of a water-steam separation device with three arranged one above the other and interconnected collectors.
  • the device 1 according to FIG. 1 comprises three collectors 2, 3 and 4, which are cylindrical and different Height, that is, one above the other, are arranged horizontally.
  • the device 1 is used for gravity separation of water and steam of a water-steam mixture, e.g. Behind an evaporation system (not shown) of a steam generator arises.
  • the first collector 2 which is also referred to below as a separator collector is referred to, in addition to a connecting pipe 6 a number of inlet pipes 8 and one Water outlet pipe 10 on.
  • the inlet pipes 8 run curved upwards, i.e. they are one above the Openings 12 in the separator 2 lying axis bent.
  • the central axis M forms the or each Inlet pipe 8 at the junction 12 in the separator 2 with the horizontal H an angle of inclination a, the is less than or equal to 60 °.
  • the second collector 3 which in the following also serves as a steam distributor is referred to, is via the connecting tube 6 with connected to the separator 2 below. He additionally has a number of steam outlet pipes 14, only one of which can be seen in FIG. 1. Of the Steam distributor 3 is connected via a return pipe 16 to the Water outlet pipe 10 connected.
  • the third collector 4 is located below the separator collector 2 arranged, which is also referred to below as an additional collector becomes. To those provided with an outlet pipe 18 Additional collector 4, a tube 20 is connected, which with the Return pipe 16 is connected. The additional collector 4 is thus via the pipes 16 and 20 with the steam distributor 3 connected.
  • the water-steam mixture flows via the inlet pipes 8 into the separator collector 2.
  • arrows 22 and 24 indicated - water W and steam D separated.
  • the steam D flows in the direction of arrow 26 through the Connection pipe 6 in the steam distributor 3.
  • the water W flows in the direction of arrow 28 over the water outlet pipe 10 in the additional collector 4. From there the water via the outlet pipe 18 into a water-steam cycle returned.
  • the connecting tube 6 projects to form a groove 30 in the interior of the steam distributor 3 in. Therefore, the return pipe 16 is in the lower Area of this channel 30 connected to the steam distributor 3.
  • groups A and B each with four inlet pipes 8, are provided on both sides of the connecting pipe.

Abstract

L'installation (1) visant à séparer l'eau (W) de la vapeur (D) d'un mélange eau/vapeur comprend, selon l'invention, deux collecteurs (2, 3) placés horizontalement à des hauteurs différentes et reeliés entre eux par un tuyau de raccordement (6). Outre ledit tuyau de raccordement (6), le premier collecteur (2), placé en bas, comprend un tuyau d'admission (8) pour le mélange eau/vapeur, ainsi qu'un tuyau de sortie (10) pour l'eau séparée (W). Le second collecteur (3), qui se trouve au-dessus du premier, comprend, outre le tuyau de raccordement (6), un tuyau de sortie de la vapeur (14) pour la vapeur séparée (D). Cette installation (1) qui fonctionne selon le principe de la séparation par gravité est particulièrement élastique du point de vue thermique et permet également un fonctionnement fiable y compris à des gradients thermiques élevés.
