Definitions

  • the present invention relates to a device for joining parallel tubular elements of circular cross section of a cyclone separator, comprising a precut plate for inlet of the fluid to be separated, on which are welded mouths of polygonal shape of the tubular elements.
  • Such joining devices are known in particular from patent FR-A-1 188672 or the corresponding patent GB-A-877257. They are however relatively fragile, owing to the fact that the separating tubular elements are only supported by the weld lines of the tubular elements between them and with the precut plate. Furthermore, the tubular elements thus suspended can enter into vibration under the effect of the flow of fluid to be separated.
  • the object of the invention is to provide a junction device which ensures a regular flow of the fluid to be separated at the inlet of the different separating tubular elements, while having a robustness close to that of the plates.
  • the joining device according to the invention is characterized in that it further comprises another plate forming a spacer for the tubes in their area with a circular cross section.
  • the precut plate comprises several sheet metal elements completing a circle in which is inscribed a polygonal paving formed by the mouths of the tubular elements, welded together along their adjacent sides, said polygonal paving being welded to said sheet metal elements on its periphery.
  • the precut plate is a circular plate pierced with polygonal orifices with respectively parallel sides and neighbors of each other.
  • the tubular elements are provided on the side of the plate precut with stamped or molded shapes, of circular cross section on the side of said elements, and flaring in a polygonal cross section at their end at the level of the plate precut, so as to form said mouths, said stamped shapes being welded to the ends of the tubular elements.
  • the ends of the tubular elements themselves are deformed on the side of the precut plate so as to have at their end a polygonal cross section.
  • the mouths of the tubular elements are hexagonal in shape.
  • junction devices of this kind are particularly suitable in vertical separators of a mixture of vapor and liquid, in particular in water vapor separators in installers for producing energy by expansion of water vapor in turbines, but they are also suitable in other types of separators, for example horizontal separators.
  • Figure 1 shows a form intended to be fixed on the end of a tubular element.
  • Figure 2 shows in plan a junction device according to the invention.
  • FIG. 3 shows on an enlarged scale a section along the axis III-III of FIG. 2.
  • FIG. 4 shows in perspective another joining device according to the invention.
  • FIG. 1 The shape of FIG. 1 comprises a hexagonal upper end 1 and a circular lower end 2, connected by a flared part 3. This shape is produced by stamping a section of circular tube, or by molding.
  • the joining device of FIG. 2 comprises such stamped or molded foundry shapes such as 4, 5, 6.
  • a precut plate is made up of several flat sheet metal elements such as 7, 8.
  • the mouths 1 of the stamped shapes are welded together along adjacent sides such as 9, and to the sheet metal elements along other sides such as 10
  • the set of welded hexagonal mouths of the stamped sheets and sheet elements reconstitutes a circular cross section, corresponding substantially to the cross section of the conduit for introducing the mixture of liquid and vapor to be separated. It can be seen that the section offered for the passage of the mixture in the separating elements is only very little less than the total cross section.
  • Figure 3 shows the method of assembling the stamped shapes and tubular elements (17, 18, 19).
  • the stamped shapes 11, 12, 13 are welded together by weld beads 14, 15 perpendicular to the plane of the figure, and they are welded in the plane 16 at the ends of the tubular elements 17, 18, 19.
  • These tubular elements are held in place by a sheet 20 forming a spacer, on which they can be optionally welded.
  • an upper plate 21 is pierced with hexagonal holes 22, with parallel sides and not far from each other.
  • a lower plate 23 forming a spacer is pierced with circular holes 24 for the passage of the tubular elements 25, 26, 27.
  • the elements 25 and 26 are shown already in place, welded into the plate 21 by their hexagonal edges such as 28.
  • L element 27 is shown during introduction in plates 21 and 23.
  • the polygonal mouths of the stamped or molded shapes or of the tubular elements can be joined other than by welding, in particular by brazing. These mouths can be in the form of regular polygons with a number of sides greater than or less than 6.
