Definitions

  • the present invention relates to a heat exchanger plate heat, especially brazed plates.
  • Such heat exchangers are for example used to heat or vaporize oxygen or an oxygen-rich fluid, in particular in air separation installations.
  • An oxygen-rich fluid is defined by a number of molecules of O 2 relative to the total number of molecules greater than 20% when the fluid is under a pressure at least equal to 20 bars, and greater than 50% at lower fluid pressures , especially more than 60%.
  • Such heat exchangers can be used for the distillation of air gases or hydrocarbons, and more particularly still in a double column of air distillation.
  • the body of a vaporizer-condenser consists of a stacking a large number of rectangular plates all identical. Between these plates are interposed on the one hand of the closing bars peripheral, on the other hand spacer waves or fins, namely heat exchange waves main vertical orientation and waves of horizontal main orientation distribution.
  • exchangers targeted by the invention are by example the main exchangers of pump apparatus, or all other plate heat exchangers, which vaporize oxygen under pressure.
  • spacer waves are obtained at from thin sheets, typically of thickness included between 0.15 and 0.60 mm, folded, cut or stamped press or other suitable tools.
  • Oxygen vaporizers are a privileged place for concentrating fuels heavier than oxygen, such as hydrocarbons, especially C 2 H 2 present in small quantities in atmospheric air.
  • Fuels heavier than oxygen such as hydrocarbons, especially C 2 H 2 present in small quantities in atmospheric air.
  • Accidental combustion in liquid oxygen can occur accidentally in such vaporizers. It has been observed that these combustions could have the consequence of producing at least local explosions.
  • thin fins, in particular aluminum fins were very vulnerable to combustion whereas the separating plates were not. It is found that the separating plates therefore make it possible to prevent the spread of inflammation.
  • a main object of the invention is to provide plate heat exchangers resistant to possible inflammation phenomena, in particular intended for use of treatment of oxygen-rich fluids, exchangers whose manufacturing costs are not significantly increased, and whose performance in terms of pressure drop and heat exchange are not significantly reduced.
  • a following plate heat exchanger the invention comprises a plurality of separating plates stacked with substantially uniform thickness, defining between them at least a first pass, and at least one fin arranged in this at least one first passage, the minimum thickness of said fin being greater than 0.8 times the thickness of each separator plate defining said passage.
  • the fin can be produced by extrusion, or by machining from a thick flat sheet.
  • the plate heat exchanger has a significantly increased mechanical resistance, this which allows you to significantly push your limits of use in fluid pressure.
  • the exchanger may also comprise, in at least one second pass, a fin whose minimum thickness is less than 0.8 times the thickness of each plate dividers defining said second passage.
  • the invention also relates to a vaporizer-condenser double air distillation column, comprising a heat exchanger as previously described, the first passage being an oxygen vaporization passage.
  • FIG. 1 two parallel separating plates 11 are shown, of the same thickness e substantially uniform for the same plate, defining between them a fluid passage 33.
  • a fin or wave 35 of generally conventional shape is arranged in niche. This fin 35 defines a main general direction of YY ripple, the waves following one another in a direction XX perpendicular to the direction YY.
  • the directions X-X and Y-Y define the planes of the separator plates 11, which are assumed to be horizontal for the convenience of description, as depicted in the Figure 1.
  • the separator plates 11 are themselves spaced along the vertical axis Z-Z.
  • the corrugated fin 35 has a large number of wavelengths 37 substantially rectangular, contained each in a vertical plane perpendicular to the direction XX.
  • the wave legs 37 are connected alternately on along their upper edge by wave vertices 39 substantially rectangular, planar and horizontal, and the along their bottom edge by wave bases 41 also substantially rectangular, planar and horizontal.
  • Wave vertices 39 and wave bases 41 define regions of connection by brazing to plates or flat separating sheets 11 of the heat exchanger.
  • the plate heat exchanger comprises a plurality of such separating plates 11 stacked and of thickness e in general substantially constant from one plate to another.
  • the plates define between them a series of passages 33, a fin 35 being arranged in each of the passages 33.
  • the fin 35 of the fluid passage 33 shown has a minimum thickness e ', said fin thickness e ' being, in the example shown in FIG. 1, uniform for the whole of the fin 35.
  • the thickness e of the separating plates is between 0.6 mm and 2 mm.
  • the minimum thickness e ' is chosen to be greater than 0.8 times the thickness e of the separating plates 11, that is to say in the case of a thickness e equal to 1 mm, greater than 0.8 mm.
  • the thickness e ′ will be given a value such that the ratio of the minimum thickness e ′ of the fin 35 to the thickness e of the plates 11 is greater than 1, more preferably still greater than 1, 5, preferably still greater than 2.
  • the fin is essentially made by folding a flat sheet thick, a sheet being defined as thick in the technique considered if its thickness is greater than about 1 mm, in particular between 1 and 2 mm.
  • the minimum thickness e 'of the fin 45 has a value meeting the conditions set out above, with reference to Figure 4.
  • the fin 45 n' is not of constant thickness and has horizontal projecting parts 47 coming from each side of the vertices 39 and wave bases 41. These protruding parts 47 make it possible to increase the contact surface of the fin 45 with the plates 11, therefore the brazing surface, and to improve the mechanical strength of the fin 45.
  • Such a fin 45 is produced essentially by extrusion, or by machining from a thick flat sheet.
  • the exchanger partly contains fins the minimum thickness of which complies with the conditions set out above, and partly fins the thickness of which is less than 0.8 times the thickness e of the separating plates 11, the latter fins being produced for example from thin sheet metal and by conventional folding methods. Therefore, such exchangers can operate with fluids having clearly differentiated pressures, the thick fins corresponding to fluids under high pressure, and the thin sheet fins corresponding to fluids under lower pressure.
