Definitions

  • the object of the present invention is a manufacturing process for wound heat exchangers, and the installation to carry out this process.
  • Heat exchangers of this type contain a large number of pipes, usually wound in a spiral round a core, and forming a number of concentric layers of pipes.
  • the usual method of manufacturing such exchangers is to lay the core horizontally and cause it to rotate on its axis, while a winder, from which comes the pipe to be wound, is moved along parallel to the axis of the core.
  • the pipe is curved to the radius it will have once wound on the core by the operation of winding, possibly completing the curve it possesses on leaving the winder, or by means of an appliance with rollers, placed between the winder and the core, or'between the winder and the layers of pipes already in position.
  • the process according to the invention allows these drawbacks to be avoided, notably because it makes turning of the core unnecessary.
  • the present invention concerns a process for manufacturing a heat exchanger of the type with a nest of tubes formed of concentric layers of wound pipes between a central core and an outside covering, means of distributing and/or collecting fluid at both ends of the nest of tubes, as well as means for transferring fluid longitudinally in the interstitial space between the wound pipes, in which the core is placed in the space 'with its axis vertical, and the pipes, previously cut to he required length, attached at one end in a distribution or collection system, wound round the said core by means of a rotary movement and a translation movement in relation to the core, and attached at the other end to the other collection and/or distribution device respectively.
  • the core is kept fixed during winding, and a pipe is wound on it by making at least one winder, acting as a container for the said pipe, revolve round the core.
  • the winders are mounted and able to rotate round the core on a crown fixed rigidly to a mobile support with an up and down translation movement.
  • the actual winding operation is performed manually by an operator for each winder, standing on the said support.
  • a template before winding on a layer of pipes, a template is prepared in accordance with the theoretical winding curve, usually a spiral, and consisting of rope, cord or rubber, which then acts as a guide for the winding of the pipes of the layer.
  • the installation includes a horizontal support which can move vertically, and means of making the said support move up or down as winding progresses, the said support surrounding the exchanger during winding.
  • the support includes a platform and removable floor sections, corresponding in number and shape to the diameters of the layers of pipes during winding.
  • the installation includes one or more winders mounted on a support which is fixed rigidly to the platform.
  • the winder or winders are mounted on a rail which surrounds the exchanger during manufacture.
  • FIG. 1 provides a view in perspective, with parts out away, of the whole installation according to the present invention.
  • FIG. 2 shows part of the installation, also in perspective.
  • a core or mount 1 is placed vertically in the installation for the winding of a sectional material, and more especially pipes 2, round the said core.
  • the whole installation is supported on an infrastructure which includes a number of vertical posts 3.
  • This installation includes a support of a particular type.
  • This support consists of unmovable section or platform 5, and segment-shaped removable gratings 6, with a central opening for the core 1.
  • the diameter of the core 1 increases, the diameter of the central opening 7 is correspondingly increased by removing the segments of grating 6 beside the opening 7, as necessary.
  • the removable gratings 6 rests on cross-bars or radial arms (not shown), fixed to the platform 5 of the support 4, themselves consisting of easily removable components side by side, or any other appropriate means, such as articulated arms, sliding diaphragms, telescopic systems, etc.
  • This installation also includes a circular crown 8,'
  • This circular crown is carried on the support by uprights 9.
  • the translation of the support 4 may be brought about by any hydraulic, electrical, mechanical or electronic means.
  • the support 4 can be translated by hydraulic jacks 12 connected to a speed-varying motor-reducing gear 13.
  • a set of stabilizing chains (not shown), may contribute to stabilization of this support 4. It is well understood that support 4 may be moved through other means, for instance by cable and winch, etc.
  • the weight of the winders 15 is balanced by counter weights 24 suspended to a line 22.
  • the spool-holders 15 can slide on the uprights 14.
  • a ring 19 moves on rollers 18 fixed to the crown; this ring is strengthened by a network of bars from which the spool-holder 15 is suspended.
  • the suspension system is only partially shown.
  • the winder contains the length of piping corresponding to the length of the theoretical winding curve for each layer of pipes, between the means of distribution and/or collection, such as, for example, manifolds or tubular plates 25 and 26.
  • the winder controlled by the ring 19, revolves round the core at an speed proportional to the speed of translation of the support. This combination of movements applies the piping more or less along the curve required.
  • the exact position is given by the concave spaces 26 between the projecting sections 27 of the ridged uprights 28 (FIG. 2), the pipe being placed manually in the concave spaces selected, by the operator.
  • the winding curve may be prepared in the form of a template, rope, rubber spring, etc, to guide the operator.
  • Ridged uprights 28 are placed between the core and the first layer of pipes, and between each succeeding pair of layers.
  • winders may be used simultaneously; one winder may contain several pipes; winding may be done in an upward or downward direction; non-ridged uprights may be used, tubular in form, so that several gases may be made to pass through these tubes.
  • the core may be placed on a rotating platform fitted with devices to reduce the stresses caused by forces of inertia, since the winder no longer has to revolve round the core.
  • the process according to the invention may be used to manufacture wound exchangers of widely varying types and sizes. It is especially useful in the case of very large exchangers, such as those used in natural gas liquefaction plants. With this process, contrary to other winding processes, the bending radii remain uniform for one layer of pipes; because of the uniform pitch and the easily checked and adjusted diameters of the layers of pipes, great evenness and precision can be obtained for the winding.
  • a process for manufacturing a very large size spiral tube heat exchanger of the type including concentric layers of wound pipes between a central core and an outer covering and means for distributing and collecting fluid at each end of the pipes and means for conveying a fluid lengthwise in the interstitial space between the wound pipes, the process comprising the steps of mounting the core substantially vertically, surrounding the core with a horizontal support comprising removable floor sections disposed in a plurality of coplanar rings concentric to the core, with said removable floor sections extending up to close adjacency to the core, attaching one end of a said pipe to one of the means for distributing or collecting fluid, winding the pipe in a spiral about the core with the pipe guided and manually positioned during the winding process by a workman standing on the removable floor sections, moving the support with the workman on it vertically along the core during the winding of the spiral pipe thereon, attaching the other end of the pipe to the other means for collecting or distributing fluid at the other end of the core, removing some but not all of said removable floor sections to accommodate the increased
