Definitions

  • the invention relates to the field of shell-and-tube apparatus, as shown in the preamble of claim 1.
  • Shell-and-tube apparatus are used normally as heat exchangers between a fluid which flows inside the tubes and a fluid which flows in the shell side.
  • Known shell-and-tube apparatus comprise baffles which have essentially two functions: a fluid-dynamic function of deviating and/or accelerating the fluid in the shell side, thus increasing the heat exchange coefficient; and a structural function for preventing vibration of the tubes;
  • US 5 058 664 and US 5 642 778 disclose a known method for manufacturing baffles consisting of a rod-baffle supported by a framework.
  • EP 2 469 215 discloses baffles formed by thin plates which intersect forming a grille and which are inclined so as to deflect the shell-side flow.
  • each single baffle is composed of several parts which need to be welded and/or fitted together and consequently the construction is relatively costly. Moreover insertion of the tubes through the baffles is a difficult operation.
  • the prior art shell-and-tube apparatus generally have a transversal shell-side flow. This term denotes that the gaseous flow outside and around the tubes is mainly directed perpendicular to the axis of tubes. This arrangement typically involves a number of passages crossing various sections of the tube bundle between consecutive baffles.
  • a transversal shell-side is generally preferred to provide a good heat exchange between the gaseous flow and the surface of tubes.
  • baffles provide a proper sealing of the tube bundle sections, to avoid gas bypass from one section to another.
  • the baffle must create a sealing collar around each tube which, however, may increase the cost and/or may render the insertion of tubes more difficult.
  • US 4834173 describes for example, heat exchangers with a transversal shell-side flow.
  • EP 3 115 734 describes baffles which allow the free insertion of tubes and their subsequent locking.
  • BE 1018891 describes a shell-and-tube apparatus according to the preamble of claim 1.
  • the object of the invention is to provide a shell-and-tube apparatus comprising a plurality of baffles which is advantageous both from the structural point of view and from the point of view of internal fluid dynamics. This object is achieved with an apparatus as described in the claims.
  • the baffles comprise a metal plate which has openings for the passage of the tubes through said baffle.
  • the baffles comprise tabs protruding from the surface of the baffle. These tabs cooperate to the fluid dynamics and/or the anti-vibrational structural function as will be explained below with the aid of examples.
  • the baffles are substantially flat elements perpendicular to the axis of the tubes (i.e. to the axis of the tube bundle).
  • the tabs extend from the surface of the respective baffle in a direction parallel to the axis of the tube bundle or in a direction inclined relative to said axis.
  • Each tab may extend over an area equal to, or less than, the area of the corresponding opening formed in the metal plate.
  • Said tabs may be configured for a fluid-dynamic function, suitable for deviating the shell-side fluid, and/or a structural function of elastically supporting the tubes. Tabs able to cause a significant deviation of the motion of the shell-side fluid are termed fluid-dynamic.
  • the shell-side gaseous flow is axial or predominantly axial. Accordingly the gas input(s) and gas output(s) of the shell side of the apparatus are arranged to provide said axial or predominantly axial flow.
  • at least some of said tabs are fluid-dynamic tabs adapted to deviate (e.g. incline of a given angle) the shell-side gaseous flow from the main axial direction.
  • the tabs of the baffles are overall arranged to give the shell-side fluid a motion component in the direction transverse to the direction of the longitudinal axis of the tubes or the tube bundle.
  • the tabs are arranged to give the shell-side fluid a substantially sinusoidal motion or a substantially helical motion.
  • An arrangement of the tabs such as to give the shell-side fluid a substantially sinusoidal flow is preferred when the tubes have a square or triangular pitch.
  • An arrangement of the tabs such as to give the shell-side fluid a substantially helical flow is preferred when the tubes are arranged on circular ranks, even though sinusoidal flows may also be obtained with the latter configuration of tubes.
  • the apparatus comprises baffles with differently configured tabs.
  • the apparatus may comprise two or more sets of baffles in which each set has a specific configuration of tabs.
  • configuration may comprise one or more features such as for example shape, size and orientation of the tabs.
  • Baffles with different configurations may be suitably distributed along the tube bundle, for example they can alternate with each other.
  • a sequence of baffles with differently configured tabs imparts a target path to the shell-side fluid, creating preferential paths across the shell side, and/or gives a certain degree of turbulence to said fluid.
  • a suitable path and/or increase in turbulence may increase the heat exchange.
  • said sequence of baffles may create supports for the tubes according to different planes for effectively dampening the vibrations.
  • the tabs of adjacent baffles rest advantageously on a same tube according to different support planes.
  • an apparatus comprises at least a first set of baffles with a first configuration of tabs, and a second set of baffles with a second configuration of tabs, wherein the second configuration is conjugate to the first configuration and the baffles of the first set and second set alternate along at least part of the tube bundle.
  • a baffle with the first configuration of tabs faces, and is adjacent to, a baffle with the second configuration of tabs, and so on.
  • the shell-side flow therefore encounters alternately tabs of the first configuration and tabs of the second configuration. Said tabs in a conjugate configuration cooperate to give the shell-side fluid a desired fluid dynamic effect. According to preferred embodiments, said fluid-dynamic effect results in essentially sinusoidal or essentially helical flow lines.
  • the embodiments with a sinusoidal shell-side flow and the embodiments with a helical shell-side flow may be combined with each other, for example by configuring the baffles for obtaining a sinusoidal flow along at least part of tube bundle and a helical flow along at least another part of the tube bundle.
  • a single baffle may comprise tabs with a different configuration. Accordingly, for example, different portions of a single baffle have a different fluid-dynamic effect.
  • the tabs may have various forms.
  • the tabs have a substantially two-dimensional form wherein one size, for example the thickness, is significantly smaller than the other two sizes.
  • the tabs have a substantially mono-dimensional form in which one size is predominant over the other two.
  • the tabs may have a polygonal form or a more complex form.
  • each opening for one or more tubes comprises at least a first region suitable for receiving the tube or tubes with play and a second region suitable for receiving the tube or tubes with less play or with substantially no play.
  • the tabs are advantageously formed so as to provide an elastic support for the tubes when the baffle is in the locking position. In this way the invention provides the further advantage of providing the system with a certain degree of elasticity and flexibility.
  • the material of the baffles is steel sheet.
  • the baffle may be a single body formed by the cut or punched metal plate or may comprise further elements such as a peripheral reinforcing ring.
  • said metal plate comprises a plurality of superimposed metal sheets.
  • the metal plate has the shape of a disc or portion of a disc.
  • Each baffle may extend over the whole of or substantially the whole cross-sectional area of the shell side, or it may extend only over a portion of said area. Baffles which cover only a part of the cross-sectional area of the shell side may be alternated with a different arrangement, for example to cover different portions of the area.
  • the advantage of the invention is given by the constructional simplicity combined with the fact that baffles actively cooperate with the fluid dynamics and/or the structural feature.
  • the invention allows to realize an apparatus in which the baffles cooperate to the internal fluid dynamics by directing the shell-side flow and further provide a yielding elastic support for the tubes.
  • the tabs projecting from the surface of the baffle act essentially like bracket elements which are able to bend and therefore provide an elastic support for the tubes.
  • the invention solves the problem by allowing a precise mounting which, at the same time, gives the system a certain elasticity owing to the ability of the tabs to flex.
  • the fluid-dynamic effect has the advantage of increasing the heat exchange coefficient and optimising the shell-side flow, exploiting the passages through the baffles for this purpose without introducing substantive additional head losses.
  • the suitably directed shell-side flow for example with sinusoidal or helical lines, runs over all tubes and allows full exploitation of the tube bundle.
  • the openings for the tubes are formed in the metal plate of the baffle, advantageously with a punching or cutting process, and said tabs are formed by strips of material of the metal plate, generated by the cutting or punching of the openings, and bent in appropriate manner.
  • Preferred cutting techniques comprise laser cutting and water-jet cutting.
  • the tabs are formed by elements firmly applied on the metal plate at the openings.
  • the tabs are sheet-metal elements applied by means of welding, preferably spot-welding (resistance welding).
  • the baffles comprise advantageously a plate with a small thickness, such that the tabs are elastic and easy to bend.
  • a reinforcing ring welded to the outer edge of the plate can be provided.
  • the second embodiments have the advantage that the thickness of the tabs may differ from the thickness of the metal plate forming the baffle.
  • the tabs may be thinner to ensure they are elastic and easy to bend.
  • a baffle comprises a metal plate of the desired thickness, with openings for the tubes obtained by means of laser cutting or water-jet cutting; the fluid-dynamic tabs are made from thin sheet metal and are applied on the baffle in the region of the openings by means of spot welds.
  • the metal plate comprises two superimposed metal sheets of different thickness.
  • a first metal sheet with a relatively large thickness has a structural function and comprises the through-openings for the passage of the tubes.
  • a second metal sheet with a smaller thickness (less than that of the first sheet) is mounted onto the first sheet and comprises the fluid-dynamic tabs.
  • Said tabs in this case, may be formed by bending the strips or part of the strips extending beyond the openings. The tabs may be bent before the insertion of tubes or during the insertion of tubes.
  • both the construction methods described above are faster and cheaper than the conventional methods which envisage forming the baffles by assembling a large number of linear elements of the bar type.
  • the invention is advantageous both for exchangers with or without the said system for locking the tubes during assembly.
  • an apparatus according to the invention is a chemical reactor for use in a chemical plant.
  • the chemical reactor may contain a catalyst in some embodiments.
  • Another advantage of the invention consists in the possibility of providing differently configured tabs on the same baffle. In this way it is possible to achieve better control of the internal fluid dynamics.
  • the invention is applicable to apparatus with straight tubes and apparatus with U-shaped tubes.
  • the baffles are applied along the straight portion of the U-shaped tubes.
  • Still another advantage of the invention is that the apparatus can have an axial or predominantly axial shell-side flow, which has a smaller pressure drop compared to transversal shell-side flow.
  • the baffles do not need to create a gas-tight seal around tubes, which facilitates their insertion. Thanks to the fluid-dynamic effect of the tabs, the invention provides a good heat exchange combined with the low pressure drop of the axial-flow design.
  • Fig. 1 shows in schematic form a shell-and-tube apparatus 1 comprising: a shell 2; a straight-tube bundle 3; a plurality of baffles 5 separated by an interval p; two tube plates 6.
  • Fig. 1 for simpler illustration, only the axes of the tubes are indicated. Moreover the central axis 20 of the tube bundle 3 which is parallel to the axes of the tubes is indicated.

  • the openings 11 may be obtained using a suitable cutting method, preferably laser or water-jet cutting, and subsequent bending of strips to form the tabs 12;
  • the tabs 12 are thin sheet-metal elements which are mounted on the disc 10.
  • Each opening 11 is passed through by a tube 4 or several tubes 4 depending on the specific embodiment.
  • Figs. 3 to 5 show an embodiment (shift lock type) in which the tubes 4 can be freely inserted into the openings 11, with a certain amount of play, when the baffles 5 are in an axially offset assembly position.

  • the tabs 112b with said second configuration protrude from the respective baffles 5b in a second direction forming with said direction of the axes 14 and 20, in the same reference plane, a second angle a2 with a sign opposite to that of the first angle a1 ( Fig. 5 ).

  • the tabs 112a, 112b are arranged on one side of the opening 11 which moves towards the tube 4 as a result of the locking displacement + f or - f , for example on the smaller side of trapezoidal openings 11. In this way the aforementioned tabs 112a, 112b provide an elastic support for the tubes 4 when the baffles 5a, 5b switch from the assembly position to the locked position.
