Definitions

  • the invention relates to a separator for separation of water and steam, with a steam-side outlet pipe and with a water-side outlet pipe and with a Separation space between a number of inlet pipes and a swirl breaker upstream of the water-side outlet pipe. It also refers to a water-steam separator, especially for a once-through steam generator, with at least one such separator, which with a Water collecting vessel is connected.
  • a centrifugal water separator is known from DAS 1 081 474, where the ratio of diameter to height is about 1: 6 and should be more. Furthermore, from the article by Jürgen Vollrath: steam separation in boiling water and boiling superheater reactors, from Technical Monitoring 9 (1968), No. 2, pages 46 to 50, known a ratio of the diameter of 52% of a separator outlet pipe on the steam side to choose the inside diameter of the separator.
  • Farther is a water-steam separation device from JP 1-31 23 04 A. known in which a water-side connected to the separator Water collecting vessel arranged at a vertical height is determined by the vertical height of the separator.
  • a separator of the generic type is for example known from GB-A-1164996.
  • a separator known from DE 42 42 144 A1 is usually used in the evaporation system of a steam generator, in particular a continuous steam generator used. Depending on Steam generator output is often several arranged in parallel Separator inside a water-steam separator connected to a common water collecting vessel. In particular when starting up such a once-through steam generator generally fall in the evaporation system large amounts of water. The or each separator serves for the separation of water and steam, the water in the Evaporator circuit returned and the steam as possible is led free of water drops into a superheater.
  • the invention is therefore based on the object of a separator for a water-steam separator, that with low pressure loss and high separation efficiency and the smallest possible wall thickness, particularly heat-elastic is. Furthermore, a suitable method is said for the operation of a number of such separators Water-steam separator for a once-through steam generator can be specified.
  • the object is achieved according to the invention solved by the features of claim 1.
  • the length of the separating space is at least 5 times the inside diameter.
  • the length of the separation chamber is defined by the distance between that through the inlet pipes of the separator determined entry level and the top edge of the swirl breaker underneath.
  • the ratio of the total flow cross section of the entry pipes to the square of the The inside diameter of the separation chamber is between 0.2 and 0.3.
  • the invention is based on the knowledge that in surprising Way with a separator, especially with a Cyclone separator, with a swirl breaker the pressure loss in the Separation room is comparatively high, while by that steam-side outlet pipe was more likely to cause pressure losses are low. Not during this behavior in the literature reproduced, however, could with a cyclone separator can be arithmetically confirmed without swirl breaker that there significant pressure losses when entering the steam side Outlet pipe and occur in the outlet pipe itself while the pressure losses in the separation room are only low.
  • the invention proceeds from the Consideration that through targeted constructive training of the separator, the pressure loss components in different Sections of the separator can be coordinated with one another in this way are that their sum with high medium throughput and more effective Separation effect reached a minimum. It sits down the pressure loss from an inlet pressure loss portion and from a frictional pressure loss share in the downward and Upward flow of the water-steam mixture entering the separator as well as from the deflection pressure loss share of the downward into the upward flow and from the inlet pressure loss portion into the steam-side outlet pipe together.
  • the mass flow density is defined as the throughput in [kg / s] divided by the cross-sectional area in [m 2 ] determined by the inner diameter in [m] of the separator and thus its separating space.
  • the inside diameter DA [m] of the steam-side outlet pipe is preferably 40% to 60% of the inside diameter of the separator.
  • FIG 1 shows a separator or cyclone separator 1 in the Longitudinal section (FIG 1a), the cross section shown in FIG 1b is.
  • the separator 1 has an upper steam-side one Outlet pipe 2 and a lower water-side outlet pipe 3 on. Below the steam-side outlet pipe 2 are in an inflow lying near its inlet opening 4 or entrance level E distributed around the circumference of the separator 1 delegated entry pipes 5 for a in water W and Steam D to be separated water-steam mixture WD provided.
  • Below the entrance level E of the inlet pipes 5 are claws 7 on the wall 8 of the separator 1 attached this in its Hold the installation position.
  • This arrangement of the inlet pipes 5 is used in the Separator 1 inflowing water-steam mixture WD on the one hand led down to the bottom area 6 of the separator 1 and on the other hand provide a twist.
  • the separation of water W and steam D takes place by centrifugal force, whereby the steam D centrally upwards and the water downwards is dissipated.
  • To break the twist in the outlet pipe 3 flowing water W is in the bottom area 6 of the A swirl breaker 9 is provided in separator 1. This prevents entrainment of steam D in the outlet pipe 3 and hindered a promotion of already separated water W back to separator 1, i.e. a reflux in its separation room 10th
  • the length A of the separating space 10 of the separator 1 defined between the entry plane E and the upper edge B of the swirl breaker 7 is at least 5 times the internal diameter DI of the separator 1
  • the ratio K between the total cross section F of the inlet pipes 5 and the square of the inner diameter DI of the separator 1 and thus of the separating space 10 is between 0.2 and 0.3, preferably between 0.21 and 0.26.
  • the steam-side outlet pipe 2 expediently has an inner diameter DA which is between 40% and 60% of the inner diameter DI of the separating space 10.
  • DA inner diameter of the steam-side outlet pipe 2
  • F KDI 2
  • a ⁇ 5DI A ⁇ 5DI.
  • the water-steam separator 11 comprises one or more Separator 1 according to FIG 1.
  • the or each separator 1 is on the water side via a connected to its outlet pipe 3 Connection line 14 with a water collection vessel 15 connected.
  • the introduction of the connecting line 14 from separator 1 into water collecting vessel 15 expediently below its water level WS, so that a calm water surface is ensured.
  • the or each separator 1 and the water collecting vessel 15 arranged to each other so that the top or upper edge OK maximum half the length L of the separator 1 reached.
  • the length L is measured between the top end OE and the lower end UE of the separator 1.
  • Half Length (1/2 L) is related to its lower end UE and thus measured from there.
  • the water-steam mixture WD generated in its evaporator 12 flows into the separator 1 via the inlet pipes 5 and is swirled there due to the at least approximately tangential inflow.
  • water W and steam D are separated from one another.
  • the separated steam D flows through the steam-side outlet pipe 2 and a steam line 16 connected to it into the superheater 13 of the continuous steam generator 13, while the separated water W flows through the swirl breaker 9 and the connecting line 14 into the water collecting vessel 15.
  • the throughput M [kg / s] through the separator 1, based on the full load operation of the once-through steam generator, is set in relation to the inside diameter DI of the separating space 10 in accordance with the relationship M 630 630 ⁇ DI 2 .
