Definitions

  • the present invention relates to exchangers and in particular exchangers intended to ensure a heat exchange between two fluids.
  • the heat exchangers using fluids consist of two circuits isolated from each other but which are in the highest possible thermal contact, and which are respectively traversed by the two fluids.
  • the maintenance of heat exchangers, and in particular their cleaning is generally a long and difficult operation to perform efficiently, or even sometimes impossible.
  • cleaning sometimes consists of eliminating, for example, the scale that has settled in the exchanger throughout the use of the latter.
  • brazed plate type exchangers are not removable and therefore their circuits are also difficult to clean.
  • the present invention aims to provide means for a user to perform such cleaning, and this simply and quickly.
  • the present invention thus relates to a heat exchanger comprising two fluid circuits isolated from each other in intimate heat exchange contact, a first fluid circuit, or beam, consisting of a spiral winding of two walls. and the second circuit being constituted by an enclosure containing the beam, each circuit having its own fluid inlet and outlet means, characterized in that the beam is elastically deformable under the effect of an overpressure or a depression.
  • the enclosure will preferably be of tubular shape and, when the internal pressure of the beam is equal to its external pressure, its external diameter will be slightly less than or equal to the internal diameter of the enclosure. The difference in diameter between the inner face of the enclosure and the outer face of the beam will be less than 6% of the diameter of the latter.
  • the tubular casing may comprise two bottoms, at least one of which may be removable, these bottoms being traversed respectively by the means of entry and exit of the fluids, and means capable of sealing between the bottoms and the input and output means of the beam fluid.
  • These inlet and outlet means may consist respectively of two longitudinal tubes and the means capable of sealing between the tubes and the bottoms may consist of O-rings or a gland.
  • the present invention also relates to a method of intervention, such as for example a cleaning, on a beam of a spiral-type exchanger comprising two fluid circuits isolated from each other in intimate heat exchange contact a first fluid circuit, or beam, consisting of a spiral winding of two walls, or a beam, and the second circuit consisting of a volume delimited by an envelope containing the beam, each circuit comprising its own input means and fluid outlet, characterized in that it comprises the steps of: subject, before removal, the beam to a depression and / or a relative cooling with respect to its envelope, so as to make it contract, once the beam extracted from its envelope interrupt the depression,
  • the beam can be made so that it is deformable under the effect of a pressure difference between the beam and the enclosure of an overpressure or a vacuum and give it a lower outer diameter .
  • the inner diameter of the envelope and apply to the beam periodic overpressures and / or depressions to change its outer diameter and break the fragile elements that can adhere to the walls (scale) that are deposited on him.
  • the method may include a preliminary step of disconnecting the beam from its circuit.
  • a limiter will be placed around the beam whose internal diameter will be equal to the maximum diameter that is wish not to exceed.
  • This limiter may consist of a ring or a sleeve.
  • Figure 1 is a schematic cross-sectional view of an exchanger according to the invention.
  • FIG. 2 is a perspective view of an exchanger forming beam shown in FIG. 1.
  • FIG. 3 is a perspective view of the envelope enclosing the beam shown in FIG.
  • Figures 4 and 5 are perspective views of a beam of an exchanger according to the invention respectively equipped with a sleeve and rings for limiting its outer diameter.
  • FIGS. 1 to 3 show an exchanger according to the invention which essentially consists of an envelope 1 which is intended to receive a beam 3.
  • the beam 3 consists of a spiral winding of two sheet sheets 5 which are spaced from each other and welded in order to provide a fluid circuit between them.
  • the spacing of these two sheets of sheet metal 5 is ensured by a series of "pins" 7 which are created and distributed over the surface of the sheet before folding it. These pins 7, once the winding performed, also ensure a regular and controlled spacing between the turns.
  • the space between the two sheets of folded sheet comprises a supply duct 9 and a discharge duct 11.
  • the envelope 1 consists of a cylindrical tube 13 whose inner diameter corresponds to the outer diameter of the beam 3, so as to receive it.
  • the casing 1, as shown in FIG. 3, has a fluid supply duct 15 and a discharge duct 17.
  • the tube 13 is closed on the one hand by a bottom 19 which is fixed and which is traversed by the exhaust duct 11 of the bundle 3 with the interposition of an O-ring seal 23 and on the other hand, at its other end, by a removable bottom 25 and which, for this purpose, is held by clamping flanges 27 which bear on a flange 29 of the tube 13.
  • An O-ring 31 ensures the seal between the cover 25 and the supply duct 9 of the beam 3.
  • the intervention can be made easier and more effective if the beam 3 is expanded beyond its nominal diameter by applying this time an overpressure. Care should be taken during this operation not to deform beyond the elastic limit of the material used, so that it can resume its nominal diameter from the end of cleaning and the interruption of the overpressure.
  • the vacuum pump is disconnected so that the beam resumes its dimensions and nominal form.
  • the beam 3 can be made to act simultaneously on the beam is depression and cooling, or the pressure and heating.
  • the beam 3 it is possible to give the beam 3 a diameter smaller than the internal diameter of the casing 1.
  • Such an arrangement is particularly advantageous in that it allows for an automatic or almost automatic elimination of fragile deposits (eg limestones ) that occur on the walls of the beam. It suffices to subject the beam, for example during its operation, to an overpressure (or depression) of the fluid that passes through it to deform and burst the tartar plates that cover it. These operations can even be performed automatically.
