Definitions

  • the present invention relates to installations for contacting a liquid against a current with a gas, in particular those used for cooling a liquid such as water with atmospheric air, and relates more specifically a device for collecting a liquid falling freely in the form of rain or the like in such installations.
  • Installations for contacting a liquid with a gas against the current generally comprise a chamber provided at its lower part with at least one gas inlet opening and at its upper part with at least one outlet opening gas and, inside said chamber, a liquid distribution network, a body for bringing the liquid into direct contact with the gas placed under the distribution network, and means for collecting the liquid which flows in free fall in the form of rain or the like of the contacting body.
  • These means can be constituted by a basin provided at the base of the chamber and into which the liquid falls directly.
  • a basin has the drawback of being a relatively expensive construction, of generating a significant noise due to the impact of the liquid falling over a significant height of the contacting body on the liquid present in the basin.
  • the aim of the present invention is to improve the flow of liquid in the chutes and is based on the observation that this poor flow is due to the significant disturbances which are created by the fall of the liquid coming from the inclined walls and entering the flow of liquid flowing in the chutes.
  • the subject of the present invention is a device for collecting a liquid falling freely in the form of rain or the like, of the type comprising a wall inclined to the vertical and a chute, hereinafter called main chute, extending along of the lower edge of the floor, characterized in that it comprises, on the path of the liquid collected by the inclined wall, and before it enters the main chute, means for significantly reducing or canceling the vertical speed component of the liquid at its entry into the chute.
  • the means for appreciably reducing or canceling the vertical speed component of the liquid comprise deflecting surfaces which give the liquid as it enters the main chute a significant speed component in the direction of flow of the liquid in the main chute.
  • deflecting surfaces can be, for example, constituted by small inclined troughs or intermediate buckets arranged at the inlet of the main chute, which give the liquid a direction close to that of the flow of the liquid in the main chute.
  • deflecting surfaces can also be constituted by ribs arranged on the inclined wall, along the line of greatest slope, and the lower part of which is curved in the direction of the flow of the liquid in the main chute or even by ribs arranged on the inclined wall and themselves inclined in the direction of the flow of the liquid in the main chute.
  • Such deflecting surfaces subject the liquid to a change of direction in the direction of flow in the main chute and give it a speed which may be greater than that of the liquid in the main chute. This decreases the disturbances in the flow, but also accelerates the flow of the liquid in the main chute.
  • the means for reducing or canceling the vertical speed component comprise one or more obstacles tending to cancel the speed of the liquid as it enters the main chute.
  • the obstacles may for example be constituted by pins arranged on the inclined wall, a rib parallel to the main chute and arranged at the entrance to the latter, or better still by a fine mesh grid covering the main chute.
  • the invention also relates to an installation for contacting a liquid with a gas against the current, comprising a chamber provided at its lower part with at least one gas inlet opening and at its upper part with at least one gas outlet opening and, inside said chamber, a liquid distribution network, a body for bringing the liquid into direct contact with the gas disposed under the distribution network, and liquid receiving devices as defined above arranged under said body to collect the liquid which flows therefrom.
  • the devices for collecting a freely falling liquid in the form of rain represented in FIGS. 1 to 9 comprise, in known manner, a wall 1 inclined on the vertical and a chute 2 called main chute extending along the lower edge of the inclined wall 1.
  • the inclined wall 1 which is planar is connected to the chute 2 by a rounded part 3 which extends downwards, towards the chute, by a short vertical part 4.
  • the chute 2 has a rounded bottom 5 and two vertical edges 6 and 7 on either side, the one, the edge 6, is in the extension of the vertical part 4.
  • the device shown in FIG. 1 comprises a horizontal succession of small inclined troughs 8 placed end to end on the vertical part 4.
  • Each small inclined trough 8 comprises a flat bottom 9 fixed on the vertical part 4 and strongly inclined relative to the vertical and a vertical edge 10 which is extended by a horizontal strip 11 inclined towards the outside of the small inclined chute 8.
  • the upper parts of the edges 10 , as well as the bands 11 of the successive small inclined chutes are fixed to one another.
  • each small inclined chute 8 parallel to this bottom. It leaves each small inclined chute 8 having a significantly reduced vertical speed component and enters the main chute 2 in the direction of the flow of the liquid in this chute.
  • each small inclined chute 12 consists of a half truncated cone whose small base 13 is closed and the large base is open.
  • Each small inclined chute is fixed to the part 4 by one of its upper edges 14 arranged horizontally.
  • the liquid is deflected by the bottom of each small inclined trough 12, parallel to this bottom and leaves each small inclined trough by the large base of the truncated cone, having a significantly reduced vertical speed component.
  • the device shown in FIG. 3 comprises a horizontal succession of buckets 15 arranged on the vertical part 4 and which each consist of a quarter of a sphere.
  • Each bucket 15 deflects the liquid which flows on the wall 1 and sends it into the chute 2 with a component of vertical speed practically canceled.
  • the device shown in FIG. 4 comprises a succession of ribs 16 arranged on the inclined wall 1 along the line of greatest slope.
  • the lower part 17 of each of these ribs at the level of the rounded part 3 is curved in the direction of the flow of the liquid in the chute 2 and deflects the liquid flowing over the wall 1 in the direction of the flow of the liquid in this chute 2.
  • the device shown in FIG. 5 includes a succession of ribs 18 arranged on the wall 1 up to the inlet of the chute 2 and inclined in the direction of the flow of the liquid in the chute 2. Thanks to these ribs, the liquid flowing on the wall 1 receives a velocity component in the direction of liquid flow in the chute 2.
  • the device shown in FIG. 6 comprises a rib 19 parallel to the main chute 2 and disposed at the entrance of the latter on the vertical edge 6. This rib has the effect of "breaking" the flow of the liquid flowing on the inclined wall 1 when it arrives in the chute 2.
  • the device shown in FIG. 7 comprises, on the one hand, nipples 20 projecting from the inclined wall intended to slow down the liquid flowing on this wall and, on the other hand, a grid 21 with fine meshes constituted by a lattice of metal wires and covering the chute 2.
  • This grid 21 has, like the rib 19, the effect of "breaking" the flow of the liquid so as to practically cancel the speed of the liquid when it arrives in the chute 2.
  • the device shown in FIG. 8 is a variant of FIG. 7; and comprises, in place of the grid with metallic wires, a grid 22 constituted by a plate provided with vertical channels.
  • the device shown in FIG. 9 is a combination of the devices shown in FIGS. 2 and 7 and comprises a succession of small inclined troughs 23 in the form of half truncated cones constituted by a lattice of metal wires which, at the same time, practically cancel the speed of the liquid which passes through them and deflects the excess of the liquid in the direction of liquid flow in chute 2.
