Definitions

  • the present invention relates to an improvement made to gas / liquid heat exchangers in which the heat exchange causes total condensation of the gas.
  • Such exchangers are used in many fields, for example for heating a liquid (acid solution at low concentration for example), and this by means of a gas at high temperature (water vapor in general) .
  • the gas / liquid heat exchanger is of the type consisting of modular elements in the form of blocks juxtaposed inside an enclosure and in which two series of channels are drilled. extending, one over the entire height of the blocks, the other over their entire width, and allowing respectively the circulation of the liquid phase and the gaseous phase between which the heat exchange must be carried out: - Said blocks being arranged inside the enclosure so as to form a column connected to its base and to its upper part to the circuit allowing the supply and circulation of the liquid phase inside the longitudinal conduits; the space between the enclosure and the aforementioned central column being separated into two chambers, one known as the intake chamber, being connected to the gas phase supply circuit and the other known as the collection chamber peration being connected to the condensate evacuation circuit formed during the heat exchange.
  • the exchanger according to the invention is characterized in that: - The introduction of the gas phase into the intake chamber is carried out by means of a distribution box making it possible to distribute said gas phase over the entire height of this chamber; - the transverse conduits drilled in the actual exchange blocks and which connect the intake chamber to the recovery chamber have a slight downward slope in the direction of circulation of the liquid phase which is formed by condensation from the incoming gas phase.
  • the exchange blocks and the enclosure which surrounds them are in cylindrical form; it is obvious that it is also possible to produce said exchanger according to the invention in a form other than cylindrical; - the gas phase distribution box over the entire height of the exchanger is arranged outside the enclosure, vertical slots being provided on said enclosure in order to distribute the gas over the entire height of the chamber, at at least one deflector being disposed, opposite said slots, in the space between the outer enclosure and the central exchange column, in order to distribute the gas over the entire surface of the column arranged inside the admission room.
  • the exchanger according to the invention is of the type made up of modular elements (1), being in the form of blocks, three in number in the example illustrated in FIG. 1, kept juxtaposed inside an enclosure (2).
  • These modular elements (1) consist of a block of material chosen according to the nature of the fluids or gases between which the heat exchange must take place and which, in this case, is graphite.
  • the blocks (1) are pierced with two series of channels (3,4) allowing independent circuits for gas and liquid to be produced.
  • the blocks (1) and the casing (2) are of cylindrical shape but it is obvious that the exchanger could have a completely different shape, for example parallelepiped.
  • the channels (3) called “longitudinal channels”, extend parallel to the axis of revolution of the blocks while the channels (4) called “transverse channels” are arranged parallel to each other between each series of longitudinal channels (3).
  • the blocks constituting the entire exchange assembly are arranged inside the enclosure (2) so as to form a central column.
  • the blocks (1) are mounted inside the envelope by means of slides (5) (only one being shown in FIG. 1) extending over the entire height of the column.
  • These slides (5) make it possible to form two chambers separated from each other in the space between the periphery of the central column and the casing, one called the intake chamber (6), the other said recovery chamber (7).
  • the supply of the liquid phase through the longitudinal conduits (3) is carried out by the base of the assembly by means of an appropriate supply circuit (8), connected to a liquid supply circuit, the evacuation being produced by the upper part by means of a discharge pipe (9) (not shown in FIG. 1).
  • the supply of the intake chamber (6) is made indirectly by opening the conduit (10) for supplying this gaseous phase, not directly inside the space between the exchange zone and the envelope , but in a distribution box (11) provided outside of said envelope (2).
  • This distribution box (11) which partially surrounds the envelope extends over almost its entire height.
  • the introduction of the gas phase inside the intake chamber (6) is carried out by providing a passage (12) in the form of a slot on the envelope.
  • This slot-shaped passage (12) can either be continuous and extend over the entire height (see FIG.
  • the distribution of the gas phase takes place over the entire height of the exchanger.
  • plate-shaped deflectors (13) can be arranged, inside the free space between the central column and the envelope, opposite the gas phase introduction slots. Thanks to such an embodiment, the gas phase is not only distributed regularly over the entire height of the exchange blocks (1), but also over the entire peripheral surface of said blocks located in the intake chamber (6).
  • the introduction of the gas phase can be carried out either by means of a single conduit (10), arranged in this case substantially halfway up the exchanger as shown in the figure 1, or possibly, as shown in FIG. 2, by means of several conduits (10a, 10b, 10c) distributed over the height of the distribution box.
  • the transverse channels (4) are not arranged horizontally but have a slight downward slope in the direction of the circulation of the liquid phase which forms by condensation from the incoming gas phase.
  • a slope of the order of 2 to 3 ° is perfectly suitable.
  • the evacuation of the condensates formed from the interior of the recovery chamber (7) is obtained by means of an evacuation duct (14) provided at the base of the recovery chamber.
  • the sections of the supply (10) and discharge (14) conduits will be calculated as a function of the flow rate of the gas phase in cross-section ratio of one third for the discharge conduit (14) to two thirds for the conduit d 'admission (10) suitable for most applications.
