Definitions
- the present invention relates to a tube bundle device arranged between two tube plates and provided with expansion lyres, for heat exchange between a fluid circulating inside the tubes and a liquid circulating around the tubes.
- the expansion lyres of such devices can be driven in vibration for certain flow rates of the fluid circulating around the tubes, in particular when the latter is a liquid alkali metal. If the excitation frequency due to the flow of the fluid approaches the resonance frequency of the expansion lyres, vibrations may occur which are sufficient to seriously damage the tubes.
- the object of the present invention is to remedy the above drawbacks, and to provide a device which does not have a special zone reserved for expansion lyres and which does not participate in the heat exchange. It also aims to ensure the operation of the expansion lyres with a more favorable working rate, outside the hottest part of the exchanger, and consequently to use tubes of smaller thickness.
- a heat exchange device comprising an external shell closed at its ends by two tube plates, a bundle of tubes fitted with expansion lyres, these tubes being connected to the tube plates to lead into the inlet and outlet manifolds of a fluid circulating inside the tubes and inlet pipes and outlet of a liquid circulating in said ferrule and around the tubes, characterized in that the expansion lyres are arranged in contact with the liquid in the coldest zone of the exchanger and in that means are provided for deflecting at least part of the liquid flow at the expansion lyres so that the liquid cannot cause the latter to vibrate.
- the means for deflecting at least part of the liquid flow rate include an inner jacket to the outer shell and in which the lyres are placed. expansion and at least one orifice formed in said shell upstream of the expansion lyres to divert at least part of the flow of liquid between the inner jacket and the outer shell.
- the steam generator has an outer shroud 1, with a vertical axis, closed at its lower and upper ends by tube plates 2,2 ′ to which the tubes such as 3 of a bundle of tubes arranged inside of the shell 1.
- These tubes open respectively, at the lower part of the steam generator, into an inlet manifold 4 for the water of the secondary circuit of the generator and at its upper part, into an outlet manifold 4 'of the water spray.
- the water to be vaporized therefore circulates from bottom to top inside the tubes 3 between the collectors 4 and 4 '.
- the liquid metal (generally sodium) circulating in the primary circuit of the generator moves against the current with respect to the water in the primary circuit, that is to say from top to bottom, inside the shell. 1 and around the tubes 3 between an inlet pipe 5 'and an outlet pipe 5.
- the tubes 3 are generally rectilinear and each define a vertical axis X. However, they each have, near their lower end connected to the tube plate 2, a dilatation lyre shown at 11 in its cold position and 12 in its hot position.
- the expansion lyres are thus in the coldest area of the exchanger, that is to say in contact with the liquid sodium, cooled in contact with the water to be vaporized.
- the expansion lyres are balanced, that is to say that the length of their branches and their position relative to the axes X of the tubes are such that the lyres exert in operation no bending reaction on the teats. 13A for joining the tubes with the tube plate 2.
- the expansion lyres 11 are arranged inside a thin jacket 6 which defines with the external ferrule 1 an annular passage through which is deflected at least part of the flow rate of the liquid sodium circulating between the ferrules inlet 5 'and outlet 5.
- the thin jacket 6 comprises above the expansion lyres 11 an annular orifice 8 through which at least part of the liquid sodium descending into the shell 1 is deflected in the annular passage formed between this ferrule and the jacket 6.
- the shell 6 extends below the expansion lyres by a perforated shell 7 welded to the shell and by which the part of the liquid sodium descending inside the shell 6 comes out in the annular passage to be discharged through the tubing 5 with the part of the sodium which has been deflected in this passage through the orifice 8.
- This perforated ferrule 7 ensures the desired distribution of the flow of liquid sodium between the internal and external zones of the jacket 6 More specifically, the passage section of the holes of the perforated shell 7 defines a sufficiently large pressure drop, relative to the passage section around the jacket 6, so that the flow of hot liquid sodium inside of the shirt is low enough not to risk causing vibrations of the lyres, expansion.
- the perforated ferrule 7 is fixed to a circular crown 9, itself connected to the tube plate 2 by bolts 10.
- FIG. 3 represents a variant of the steam generator of FIG. 2 in which the expansion lyres such as 13 are symmetrical with respect to the general axis X of the corresponding tube (the position of the hot lyre is represented at 14).
- This has the advantage of reducing the transverse size of the lyres and therefore the diameter of the ferrule 6.
- the length of the lyres is increased and they exert in operation a certain bending force on the corresponding teats of the junction of the tube with the tube plate (not shown).
- Figure 4 is a sectional view along the axis IV-IV of Figure 2 and Figure 5 a detail view V of Figure 4. These figures show the staggered distribution of the tubes such as 13, 14, 15, 16, and the bars such as 17, 18 , 19 slid between the rows of tubes to increase safety vis-à-vis their vibrations.
- FIG. 6 a variant of FIG. 2 according to which the area internal to the shell 6 containing the expansion lyres 11 contains liquid sodium in the static state and not in circulation.
- the perforated shell 7 is eliminated and the shell 6 is connected directly to the tube plate 2.
- the arrows illustrate in FIG. 6 the entire flow of liquid sodium s' made from the outside of the shell 6, through the orifices 8.
- the members for distributing the flow between the internal and external zones relative to the envelope may be other than a grid with calibrated holes. They can also be arranged upstream of the internal envelope, and no longer downstream of the latter.
- the invention applies to tube bundle heat exchangers with expansion lyres, in particular for a steam generator with a primary fluid consisting of a liquid alkali metal.
