Definitions

  • the present invention relates to an air separation apparatus comprising a plate heat exchanger, in particular to brazed plates and to the use of an exchanger for heating and / or vaporizing a liquid rich in oxygen.
  • Such heat exchangers are for example used to heat or vaporize oxygen or an oxygen-rich fluid, especially in air separation plants.
  • An oxygen-rich fluid is defined by a number of O 2 molecules relative to the total number of molecules greater than 20% when the fluid is under a pressure of at least 20 bar, and greater than 50% at lower fluid pressures. , especially greater than 60%.
  • Such heat exchangers are used for the distillation of gas from the air, and more particularly in a double air distillation column.
  • the body of a vaporizer-condenser consists of a stack of a large number of vertical rectangular plates all identical. Between these plates are interposed on the one hand peripheral closure bars, on the other hand spacer waves or fins, namely heat exchange waves of vertical main orientation and distribution waves of horizontal main orientation.
  • EP-A-1026468 discloses an air separation apparatus according to the preamble of claim 1.
  • exchangers covered by the invention are, for example, the main heat exchangers of pump units, or any other plate heat exchanger, which vaporize oxygen under pressure.
  • the spacer waves are obtained from thin sheets, typically of thickness between 0.15 and 0.60 mm, folded, cut or stamped with the press or by means of other suitable tools.
  • Oxygen vaporizers are a privileged place of concentration of heavier fuels than oxygen, such as hydrocarbons, especially C 2 H 2 present in small amounts in atmospheric air. It can happen accidentally, in such vaporizers, combustion in the liquid oxygen. It has been observed that these combustions could have the consequence of producing at least local explosions. In accidents of this type, it has been found that thin fins, in particular aluminum fins, were very vulnerable to combustion while the separating plates were not. It can be seen that the separating plates consequently make it possible to prevent the spread of the inflammation.
  • a main object of the invention is to provide air separation devices having plate heat exchangers resistant to possible ignition phenomena, in particular for use in the treatment of oxygen-rich fluids, exchangers whose manufacturing costs are not increased significantly, and whose performance in terms of pressure drop and heat exchange are not significantly reduced.
  • the fin can be made by extrusion, or by machining from a thick flat sheet.
  • the plate heat exchanger has a substantially increased mechanical strength, which allows to significantly push back its limits of use in fluid pressure.
  • the exchanger may further comprise, in at least a second passage, a vane whose minimum thickness is less than 0.8 times the thickness of each of the separator plates defining said second passage.
  • FIG. 1 shows two parallel separating plates 11 having the same substantially uniform thickness e for the same plate, defining a fluid passage 33 between them.
  • a fin or wave 35 of conventional general shape is disposed in niche.
  • This fin 35 defines a main general direction ripple YY, the waves succeeding in a direction XX perpendicular to the direction YY.
  • the X-X and Y-Y directions define the planes of the separator plates 11, which will be assumed to be horizontal for the convenience of the description, as shown in FIG. 1.
  • the separating plates 11 are spaced along the vertical axis Z-Z.
  • the corrugated fin 35 has a large number of substantially rectangular wave legs 37, each contained in a vertical plane perpendicular to the X-X direction.
  • the wave legs 37 are connected alternately along their upper edge by substantially rectangular, plane and horizontal wave peaks 39 and along their lower edge by wave bases 41 which are also substantially rectangular, flat and horizontal. .
  • the wave peaks 39 and the wave bases 41 define solder connection regions to flat plates or separator plates 11 of the heat exchanger.
  • the plate heat exchanger comprises a plurality of such separator plates 11 stacked and of thickness e generally 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 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 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 greater than 1, 5, more preferably greater than 2.
  • the fin is made essentially by folding a thick flat sheet metal, a sheet being defined as thick in the technique in question if its thickness is greater than approximately 1 mm, in particular between 1 and 2 mm.
  • the minimum thickness e 'of the fin 45 has a value satisfying the conditions stated above, with reference to FIG. It is not of constant thickness and has horizontally projecting portions 47 on each side of the vertices 39 and 41 wave bases. These protruding portions 47 make it possible to increase the contact surface of the fin 45 with the plates 11, and thus the brazing surface, and to improve the mechanical strength of the fin 45.
  • Such a fin 45 is made essentially by extrusion, or by machining from a thick flat sheet.
  • the exchanger in part, fins whose minimum thickness is in accordance with the conditions set out above, and for part of the fins whose thickness is less than 0.8 times the thickness e of the separator plates 11, the latter fins being made for example of thin sheet and by conventional folding methods. Therefore, such exchangers can operate with fluids with clearly differentiated pressures, thick fins corresponding to fluids under high pressure, and fins in thin sheet corresponding to the fluids under lower pressure.
