Definitions

  • the invention relates to a phase distributor container for a gas-liquid mixture, according to the preamble of claim 1.
  • the combustion chamber of such a steam generator is preferably formed by vertical tubes in which water flows through, which is heated by the combustion gases in the interior of the combustion chamber, from bottom to top. Since the heat distribution within the combustion chamber is not ideal, the heat absorption by the water in the different pipes is unequal and the water-steam mixture that emerges at the upper end of the pipes shows considerable differences in state. For this reason, they are fed to phase distribution containers in the form of collectors, from which a water-steam mixture which is in the same state is to emerge in all discharge lines. In practice, however, large deviations from the target value can often be determined, which is easy to understand with the aid of FIG.
  • phase distributor container In area D the amount of steam predominates, and thus the friction pressure losses, the main problem being the distribution of the small amount of water. In area E, where there is only steam, it must be distributed so well that the temperature is evened out. The phase distributor container must therefore be able to perform the correspondingly different tasks in all of these very different operating areas. However, the known phase distributor container works satisfactorily in at most one of these areas and has a poorer performance in the other areas.
  • phase distribution container of the type described, which keeps the level better constant under all circumstances than according to the prior art and with any gas-liquid mixing ratio, such as water-steam in all mentioned areas A. , B, C, D and E, works optimally, while the constructive, manufacturing and cost-effective effort remains low.
  • the bands F show these deviations in a collector-like phase distributor container according to the prior art and the bands G the corresponding deviations in the same collector, modified according to the features of the invention.
  • the bands F and G cover the measurement results of different measurements per E L value and thus show that the measurement scatter due to various interfering influences is about 4 times greater in the prior art than in the invention, additional proof of the advantages of the invention.
  • the first implementation of the invention is carried out very roughly: even better results can be expected if the phase distribution container according to the invention is designed carefully.
  • An additional advantage of the invention is its applicability to existing phase distribution containers only by adding at least one partition. Another additional advantage is the substantial strengthening of the phase distribution container by the partition, whereby lighter, less expensive Construction methods are possible.
  • Claim 2 represents a preferred embodiment of the invention similar to the discussed prior art.
  • phase distributor container favors a very advantageous symmetrical arrangement of the supply and discharge lines along the phase distributor container.
  • the embodiment according to claim 4 enables the supply and discharge lines to be separated in groups along routes, which is very favorable in many applications.
  • This embodiment can be implemented particularly simply according to the feature of claim 5.
  • the arrangement of the feed lines according to claim 6 favors a rapid separation of the two phases, in that the usual separation of the two mixture phases by gravity is additionally supported by a centrifugal force by deflecting the inflowing mixture at the bottom of the inlet chamber.
  • the arrangement of the supply and discharge lines according to the features of claim 7 leads to a favorable manufacturability of the phase distributor container according to claim 6 and to a good arrangement of the mouth openings to the discharge lines with respect to the level in the outlet chamber.
  • the design of the opening to the discharge line according to claim 8 causes the outflowing gas facing liquid surface is the same at all levels, so that the amount of liquid entrained by the gas remains approximately the same with small level differences.
  • phase distributor container 3 and 4 essentially consists of a horizontally extending tubular phase distributor container 1, closed at both ends by means of tightly welded circular end plates 40.
  • a partition 15 is bent in such a way that it forms a U-shaped channel running inside the phase distributor container 1 and running along this and firmly welded to the two end plates 40.
  • the interior of the phase distributor container 1 is divided into two chambers by the partition wall 15: an inlet chamber 2, which is surrounded by the partition wall 15, and an outlet chamber 3, which surrounds the partition wall 15.
  • two gas passage openings 11 are provided, through which the inlet chamber 2 and the outlet chamber 3 are connected.
  • Both chambers are also connected by liquid passage openings 12, which are arranged in the form of round holes on the horizontally running part of the partition wall 15 which serves as the bottom of the inlet chamber 2 are.
  • Feed lines 20 run essentially vertically and must enter the inlet chamber 2 after they have been bent slightly towards 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 supply 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 are in the same height range.
  • the supply line 22 and the discharge line 30 run symmetrically to a vertical plane through the longitudinal axis of the collector-shaped phase distributor container 1 and are identical to one another and also present in the same number.
  • a partition wall 10 ' between an inlet chamber 2' and an outlet chamber 3 ', only consists of a piece of sheet metal running vertically and asymmetrically along the phase distributor container 1 with a slightly bent-down liquid passage openings 12' in the form of round holes in the lower region which piece of sheet metal is welded to both end plates 40.
  • a slot between an edge in the upper region of the partition wall 10 'and the phase distributor container 1 forms the gas passage opening 11'.
  • FIG. 11 A special feature of this embodiment is shown with the aid of FIG. 11.
  • the outlets to the discharge lines 30 are here provided with covers 36 which are welded to the discharge lines 30 and one have rectangular opening 35.
  • the rectangular opening 35 has the effect that, regardless of the level 31 in the area of the mouth to the discharge line 30, the same liquid surface is always exposed to the gas flow and, as a result, small level fluctuations as a result of vibrations or, for example, impacts have little influence on the distribution of the phases in the discharge line 30.
  • Another advantage of this embodiment is that a different cross-sectional size can be selected in the area of the mouth mentioned than in the corresponding discharge line 30 and that a more favorable gas velocity can be provided here.
  • shapes other than a rectangle for the openings are possible, such as round, square or polygonal shapes.
  • a partition 10 consists of a vertical sheet, which is arranged symmetrically through the center of the phase distributor container 1 and is welded to the phase distributor container 1 itself and to the end plates 40. Rectangular gas through openings 11" and liquid through openings 12 "are cut out above or below along the wheels of the partition 10 ".
  • Feed lines 23 run vertically and penetrate the wall of the phase distributor container 1 on one side of the partition wall 10 ′′, so that the mixture enters from the bottom up in an inlet chamber 2 ′′ and the mouths of the feed lines 23 from the liquid phase in the inlet chamber 2 "Discharge lines 32 also run vertically, penetrate the phase distribution container 1 on the other side of the partition 10" and the level 31 of the liquid phase in an outlet chamber 3 ".
  • the mouth of each discharge line 32 is given the shape of a through an oblique cut inclined ellipse through which the escaping gas phase of the mixture flows through at different levels 31 and entrains liquid phase in the known manner.
  • This embodiment is particularly interesting if the mixture has a large proportion of the liquid phase and flows into the inlet chamber 2 "at a relatively low speed, because then the gaseous phase can simply escape from the liquid phase in the region of the inlet chamber 2". Since the mixture emerging from the feed lines 23 is intercepted and distributed by the liquid phase lying in the inlet chamber 2 ", no liquid is splashed around in the area of the inlet chamber 2" and subsequent mixing of the separated phases is avoided. Otherwise, this embodiment of the invention works in the same way as the previously described.
  • FIGS. 9 and 10 illustrate an example of the invention in which the tubular phase distribution container 1 is no longer divided in its longitudinal direction, but perpendicular to it.
  • different inlet chambers 2 ′′ ′′ and outlet chambers 3 ′′ ′′ are arranged one behind the other, in each case separated from one another by means of disk-shaped partition walls 16.
  • Each partition wall 16 has a gas passage opening 11 ′′ ′′ in the upper region and two liquid passage openings 12 ′′ ′′ in the lower region of the phase distributor container 1 there are three rods 17 made of a round rod, which penetrate both the partitions 16 and the end plates 40 and are welded tightly to each so that they are carried by the end plates 40 and in turn carry the partitions 16.
  • Feed lines 24 run vertically and open, three inlet chamber 2 ''', at the top of the phase distributor container 1. in each outlet chamber 3''open out symmetrically to a vertical plane through the longitudinal axis of the Phasenvertellerbeh d lter 1, six discharge pipes 30.
  • the operation of this Ausbowungs example is the same as that of the embodiments of FIGS. 3 and 4, 5 and 6, and 7th
  • the partition wall in each of the examples shown can additionally be reinforced against vibrations, both by means of connections between the partition wall and the phase distributor container wall, and by the choice of thicker sheets as the partition wall material. None of these measures has a disruptive effect on the functionality of the invention.
  • Partition wall means not only a smooth, uniform sheet metal wall, but also, for example, a corrugated or zigzag wall. It is also possible to give the partition the shape of a flat static mixing element. In this embodiment, it is sufficient that the stable level in the outlet chamber is adequately protected from the turbulence in the inlet chamber.
