Definitions

  • the present invention relates to a static heat exchanger with a metal tube bundle making it possible to recover the heat from a gas or smoke stream to heat a second gas stream.
  • This exchanger is in particular intended for the recovery at high temperature of the heat of combustion fumes from ovens or gasifiers to allow the heating of combustion or drying air.
  • the present invention further aims to provide a heat exchanger provided with several outlets for taking the gas heated at different temperatures. It leads to a circulation of the gas to be heated such that there is: a cooling of the tubular plates, a symmetrical evolution of the temperatures starting from the tubular plates towards the central outlet of the gas to be heated, a uniform circumferential distribution of the temperatures in any plane perpendicular to the axis of the exchanger. This results in the use of thin tubular plates, limited thermal stresses and the use of steels with little or no refractory.
  • the exchanger comprises a plurality of metal tubes, the ends of which terminate in tubular plates and which channel a first stream of hot gas, these tubes being housed in an enclosure closed by said tubular plates and provided with '' an inlet and an outlet for a stream of gas which circulates around the tubes and it is essentially characterized in that the enclosure has lateral inlets located near the tubular plates and lateral outlets located between said inlets so that the enclosure is crossed by two streams of gas flowing in opposite directions from the tubular plates to the said outlets and on the other hand from the internal partitions traversed by the tubes and forming baffles for the flow of the gas which passes alternately in the center and on the periphery of the enclosure.
  • the exchanger has intermediate outlets making it possible to draw gas between the inlets and the outlets.
  • each tubular plate is joined to the rest of the enclosure by a compensator.
  • At least one partition is held to a deflector having a shape of revolution and that the gas to be heated.
  • the single figure is a longitudinal section of the exchanger according to the invention.
  • the exchanger according to the invention comprises a plurality of metal tubes 1 which extend parallel to the longitudinal axis 11 of the exchanger.
  • the ends of these tubes end on tubular plates 21 and 22 to which they are welded.
  • Sleeves 6 are mounted at the ends of the tubes to protect the welds.
  • the tubular plates 21 and 22 form part of a closed enclosure 2 in which is housed the bundle of tubes 1.
  • a current of hot gas or hot smoke is brought by a conduit 31 to the entrances of the tubes flush with the upstream tubular plate 21.
  • the outlets of the tubes flush with the downstream tubular plate 22 open into a conduit 32 which channels the gas at the outlet of the exchanger to evacuate.
  • the enclosure is composed of ferrules 25, 26, 27 welded together so as to form a conduit or a chamber closed at its ends by the tubular plates 21 and 22.
  • Each tubular plate 21 or 22 is joined to the ferrule 25 or 26 of the enclosure by means of a bellows expansion compensator 23 or 24.
  • the enclosure 2 comprises, near the upstream tubular plate 21, a first set of inlet pipes 41 which are mounted laterally and open inside by inlet orifices 411. It also comprises near the tubular plate downstream 22, a second set of inlet pipes 42 which are mounted laterally and which open inside through inlet openings 421. These inlet pipes 41 and 42 serve to introduce a second current into the enclosure. gas intended to be heated by convection. Between the sets of inlet pipes, in the middle part, the enclosure comprises a set of outlet pipes 43 which are mounted laterally and open out through orifices 431. Between each set of inlet pipes 41 or 42 and the set of outlet pipes 43, the enclosure comprises a set of intermediate pipes 44 and 45 which are mounted laterally and which open inside through orifices 441 and 451. These intermediate pipes allow the heated gas to be taken at intermediate temperatures.
  • each set has three tubes arranged at 120 ° one from the other.
  • Partitions 51 and 52 are mounted inside the enclosure, perpendicular to the tubes which pass through them.
  • Each partition marked 51 provides a central opening and has the shape of a flat ring crossed by a part of the bundle tubes.
  • Each partition marked 52 provides an annular opening with the enclosure for the passage of gas.
  • the partitions 51 and 52 are arranged alternately so as to form baffles for the flow of gas which passes alternately through the central openings of the partitions 51 and through the peripheral annular openings formed by the partitions 52.
  • Each end partition 51 with central opening is located closer to the nearest tube plate 21 than the inlet pipes 31.
  • This partition is integral with a deflector 53 which is fixed to the enclosure 2 beyond the pipes d 'Inlets 41.
  • This deflector forms an annular space into which open the orifices 411. This space is open towards the tubular plate 21 so as to deflect the gas flow towards the space between the partition 51 and said tubular plate.
  • One of the partitions 52 providing an annular opening for the gas is joined to a flange 54 of flared shape, in the direction of flow of the gas, and which is fixed inside the enclosure.
  • This collar forms an annular chamber into which the lateral orifices 441 of the intermediate tubes 44 open.
  • This collar is provided with lateral orifices 541 which allow the passage of gas towards the outlet tubes 43.
  • partitions are integral with ferrules of revolution such as the deflectors 53 or 54, these ferrules, welded to the enclosure, allowing the expansions.
  • Other partitions are held by fasteners allowing radial expansions.
  • the tubes pass with clearance in the partitions 51 and 52.
  • the tube bundle is not supported by the tubular plates but it is supported by the partitions 51 and 52 which are vertical.
  • the conduits 31 and 32 are insulated by a layer of insulation.
  • the exchanger is also insulated by an insulating layer 4 enveloping it externally.
  • the enclosure 2 can be protected internally, in its middle part, by an insulating sleeve of metallic or refractory insulation 5 fixed on the internal wall.
  • the relatively cold gas that one seeks to heat is brought into the enclosure by the pipes. inlet 41 and 42. It flows around the tubes 1 in two opposite currents (shown by the arrows). Each current flows in a zigzag fashion, from the tubular plate towards the middle of the exchanger, passing alternately through the central openings formed in the partitions 51 and through the peripheral openings formed by the partitions 52. After reheating in contact with the tubes 1, the hot gas is evacuated through the outlet pipes 43. In the process, gas at intermediate temperature is taken off through the intermediate pipes 44 and 45.
  • the two tubular plates 21 and 22 are, on the inner side, in contact with cold gas and the expansions are carried out symmetrically from the median plane passing through the axes of the outlet pipes.
