Definitions

  • the present invention relates to an atmospheric trickle refrigerant.
  • an atmospheric trickle refrigerant of the type comprising a shell having peripheral lower air inlet openings and, arranged inside this shell, a distribution network of a liquid to be cooled, a body of contacting extending under the distribution network and liquid receiving devices, with chutes, arranged under the contacting body.
  • Refrigerants of this type find application in particular in the cooling of water from power plants.
  • the tower-shaped shell rests on oblique pillars integral with each other.
  • the water to be cooled arrives at the center of the tower and is recovered after runoff by the chutes which return the cooled water again to the center of the tower from where it is discharged.
  • valves allowing bypass that is to say the direct passage from the hot water inlet to the cold water outlet, are difficult to access.
  • the present invention aims to remedy these various drawbacks.
  • an atmospheric trickle refrigerant of the type comprising a shell resting on independent batteries regularly distributed at the periphery and, arranged inside this shell, a distribution network for a liquid to be cooled, a contacting body extending under the distribution network and liquid receiving devices, with chutes, arranged under the contacting body, characterized in that the shell of the refrigerant rests on the batteries, via a wide peripheral lintel, which comprises, at its upper part, an internal rim and an external rim forming a peripheral basin in which the cooled liquid collected in the chutes is discharged by gravity.
  • the internal rim of the peripheral pelvis can be formed by the shell itself.
  • the shell advantageously comprises an internal peripheral tank communicating with the peripheral basin, so as to collect the water flowing on the internal wall of the shell and to discharge it towards the peripheral basin.
  • the hull can also rest on the peripheral lintel by means of pillars, the internal rim of the peripheral basin then being located inside the cooler, below the vertical of the bottom of the hull, so as to collect the water flowing on the inner wall of the hull.
  • Fig. 1 represents an atmospheric refrigerant 1 according to the present invention, in horizontal section, the cutting being carried out at three different levels, namely; at the level of the batteries, at the level of the chutes and at the level of the distribution network of the liquid to be cooled.
  • the atmospheric refrigerant 1 is in the form of a hyperbolic torus and rests on a series of batteries 2 themselves resting on bases 3.
  • the batteries 2 are regularly distributed around the periphery of the atmospheric refrigerant. In horizontal section, their largest dimension is oriented along radii; their section comprises a central rectangular part and is terminated upstream and downstream by a rounded part. -.
  • annular lintel 4 slightly wider than the largest dimension of the stacks in section. This very rigid lintel rests on the piles 2 by means of support wedges 5.
  • the lintel 4 further comprises, at its upper part, an external rim 7 which forms with the lintel 4- and the lower part of the shell 6 a basin 8 which is intended to collect the cooled liquid.
  • the liquid to be cooled (generally water) is brought from the ground by two vertical columns 9 arranged in the vicinity of the center of the atmospheric refrigerant.
  • the liquid arriving through these columns 9 is then poured into two substantially horizontal distribution channels 10 (or galleries) which are provided with lateral tubes 11 for distributing the liquid to be cooled, themselves provided with a large number of spray nozzles.
  • Under these distribution tubes 11 are arranged packing elements 12 ensuring contact between the liquid to cool and the air entering the lower part of the refrigerant between the batteries 2.
  • Under these lining elements 12 is arranged a series of inclined walls 13 ending in troughs 14.
  • These troughs 14 are arranged along two slopes allowing their discharge into a manifold 15 passing through the center of the refrigerant.
  • This collector 15 opens itself, through an orifice 16, into the peripheral basin 8.
  • a peripheral tank 17 On the inner wall of the shell is arranged a peripheral tank 17, substantially at the level of the troughs 14, which communicates with the peripheral basin 8 through orifices 18.
  • the peripheral basin 8 has an outlet 19 for the cooled liquid disposed substantially in the extension of the manifold 15. This outlet brings the cooled liquid to a pipe 20. It has a cofferdam system 21 allowing the control of the outlet of the liquid cooled from the peripheral basin 8.
  • the distribution channels 10 pass through the shell 6 and open out above the peripheral basin 8. Their end is provided with a by-pass valve 22.
  • the opening of this valve 22 makes it possible to directly evacuate the liquid to be cooled in the peripheral basin 8 while lowering the level of the liquid sufficiently enough to no longer send liquid into the distribution tubes 11.
  • Such a bypass is intended in particular to allow rapid stopping of the flow of water reaching the packing elements in the event of an intense cold period to avoid the formation of gel on these packing elements.
  • FIG. 5 Another mode for carrying out the invention.
  • the shell 6 rests on the peripheral lintel 4 by means of pillars 23 regularly spaced.
  • the lintel 4 then has at its upper part an internal rim 24 located inside the refrigerant, below the vertical of the bottom of the shell 6, forming with the lintel proper and the external rim 7 a peripheral tank 8.
  • This embodiment makes it possible to delete the peripheral tray 17.
  • FIG. 6 Another embodiment of the flow of the cooled liquid from the troughs 14 to the peripheral basin 8.
  • the troughs 14 pass through the wall of the shell 6 and open into the peripheral basin 8.
  • the peripheral tank and the central manifold are eliminated and the slope of the troughs 14 is in the opposite direction, that is to say that their lower outlet is on the side of the shell 6.
  • the atmospheric refrigerant according to the present invention has many advantages over the prior art.
