Definitions

  • the present invention relates to forced ventilation air condensers, that is to say essentially devices containing heat exchangers between a fluid to be condensed (generally water vapor; optionally ammonia, or any other liquid, such as freons, easily condensable at ambient temperatures) and atmospheric air set in motion by fans.
  • a fluid to be condensed generally water vapor; optionally ammonia, or any other liquid, such as freons, easily condensable at ambient temperatures
  • These heat exchangers are made up of batteries of inclined condenser tubes, these batteries forming two by two an inverted V and being supplied by a pipe for supplying the steam to be condensed disposed at the tip of the inverted V.
  • This inverted V configuration is called "delta”.
  • Axial fans with a vertical axis of rotation, placed in the acute angle of the inverted V, at the base of this inverted V draw in ambient air and blow it through the batteries.
  • the present invention relates more specifically to the structures of such air condensers, that is to say the mechanical elements supporting the batteries of tubes and the fan-motor groups, which ensure the mechanical stability of the assembly on the ground.
  • the aim of the present invention is to reduce the cost of air condensers compared to other air condensers equipped with identical tube batteries and motor-fan units, without altering the thermal performance of these devices, for identical mechanical stability (in particular stability wind and resistance to seismic stresses).
  • the subject of the present invention is an air-cooled forced air condenser, of the type comprising batteries of inclined condenser tubes, said batteries forming two by two an inverted V, a steam supply line to be condensed arranged at the tip of the Inverted V and supplying steam to said batteries, and at least one motor-fan unit disposed under said batteries at the base of the inverted V, characterized in that it comprises a metal frame constituting a truss beam extending in a longitudinal direction horizontal and having a triangular cross section comprising two inclined sides and a horizontal base, the two inclined sides supporting said batteries and the base supporting the motor-fan group (s).
  • the platform that is to say a two-dimensional structure
  • the platform has been replaced by a three-dimensional structure with a triangular section, considerably increasing the rigidity in the longitudinal direction.
  • the new infrastructure composed of this three-dimensional framework and supports is much lighter and less expensive than the old one, in particular due to the fact that the number of supports may be greatly reduced.
  • the metal frame extends over several cells each comprising a motor-fan group and several batteries (4 or 6, in general, opposite 2 to 2).
  • Each cell is preferably square and centered on the motor-fan unit, which is better for the distribution of air.
  • the air condenser advantageously comprises several rows of cells.
  • FIGs. 1 and 2 there is shown a cell 1 of an air condenser according to the invention.
  • This cell 1 consists of a metal frame 2 extending in a horizontal longitudinal direction and having a triangular cross section called the delta.
  • This framework comprises two inclined sides 3 and 4 forming an inverted V and a horizontal base 5.
  • This metal frame 2 supports on each of its sides 3 and 4 three batteries of tubes 6.
  • a steam supply pipe 7 arranged horizontally and supplying the batteries 6.
  • each group of batteries 6 At the bottom of each group of batteries 6 is arranged a pipe 8 for the return of the condensate and, at the top of each group of batteries is arranged a pipe 9 for discharging the non-condensable gases.
  • This metal frame 2 also supports at its base 5, by means of the two beams 19, a motor-fan unit 10 comprising a fan 11, driven by a motor 12 by means of a reduction gear 12a, and a ferrule 13 surrounding the fan.
  • the beams 19 are covered with a grating 14 constituting a walkway, which is surrounded by a railing 15. Plates 16 furthermore seal the sides 3 and 4 between the base 5 and the batteries 6.
  • plates 17 seal the base around the shell 13 of the motor-fan unit.
  • the metal framework 2 of cell 1 is shown in more detail in FIGS. 3 to 5.
  • the base 5 of the framework 2, as shown in FIG. 4 is constituted by a grid of metal beams.
  • This grid comprises longitudinal metal beams at 1 18 arranged at the two lateral ends of each cell, transverse beams at 1 20 between the longitudinal beams 18 at the longitudinal ends of each cell, longitudinal beams at 1 19 arranged in the vicinity of the center, transverse beams 21 between the beams 19, as well as diagonals such as 22 intended to increase the rigidity of the base.
  • the beams 19 and 21 support the motor-fan unit 10.
  • the sides 3 and 4 of the framework 2 are formed, as shown in FIGS. 3 and 5, by a wire mesh.
  • This trellis includes bars 23 forming between them an inverted V and arranged in planes orthogonal to the base 5 at the two longitudinal ends of the cell 1.
  • the trellis further comprises diagonals 25 disposed between the bottom of the bars 23 and the tube 24 midway between the bars 23.
  • FIGs. 6, 7 and 8 there is shown in Figs. 6, 7 and 8 an air condenser comprising a set of twenty four cells such as that which has just been described.
  • the cells are arranged in four rows 28, 29, 30 and 31, each row comprising six cells aligned in the longitudinal direction. Each row is surmounted by a steam supply pipe 7 which supplies the batteries of tubes in the row.
  • the set of cells rests on a set of twelve supports 32a, 32b, 32c, 32d, 32e, 32f, 32g, 32h, 32i, 32j, 32k and 321.
  • These supports consist of metal columns fixed to the base 5 of the cells and are arranged between each row of cells and at the lateral ends of the air condenser.
  • the supports 32a and 32e are present between the first and the second cell of each row and the legs 32h and 321 are present between the fifth and the sixth cell of each row.
  • the columns 32f and 32g are arranged between the fourth and the fifth cell of the rows, only at the lateral ends of the air condenser.
  • the columns 32b and 32c, on the one hand, and 32i and 32j, on the other hand, are part of a brace 33 extending in a vertical plane perpendicular to the rows and intended to ensure the stability of the air condenser at transverse stresses.
  • diagonals 34 are provided between the columns 32f and 32h, on the one hand, and 32g and 321, d on the other hand, in a vertical plane parallel to the rows.
  • the rigidity of the framework of the air condenser in the longitudinal direction is such that the span between the supports can be several cells, for example three or four cells; moreover, the end cells may be cantilevered.
  • Another advantage of the new design of the air condenser framework is an easy adaptation to the conditions specific to each site, given the latitude allowed on the position of the support legs.
