Definitions

  • the present invention deals with a module for a device for generating a curtain for either confining a region of space or for a cooling tower, and the device corresponding thereto.
  • the present invention deals with a device for generating a water curtain (or a liquid sheet) for confining an environment where different types of pollutions, acoustic, thermal, gaseous and particle, are present and may occur simultaneously or independently, or for a cooling tower.
  • This device can deal with one of the above-mentioned pollutions or all four.
  • the confinement of objects which are the source of these pollutions is a problem frequently encountered in an industrial context but also in a public context.
  • the invention can be used for the confinement of all types of machines emitting such pollutions, such as boilers, motors, pumps, turbines, etc.
  • Document FR 2 641 201 discloses a double water curtain for confining an area of space susceptible to air pollution, but that only creates a simple curtain without a closed outline and does not ensure continuity of the liquid sheet proposed by the present invention.
  • the invention refers to the reception of one or two liquid sheets allowing the confinement of the polluted environment to be maintained, without provoking or moving the pollutions towards the environment to be protected.
  • a water cooling receptor such as that described in document US 4 130 613 , allows the collection of the water falling from a cooling tower and to prevent noise from the fall spreading outward.
  • the scope of the application and the intrinsic design of the system are not the same as in the present invention.
  • a reception device for free-falling liquid described in document US 4 385 010 allows the reduction or elimination of the vertical speed of the liquid, but does not allow noise pollution to be limited.
  • aspects of the present invention have a receptor of one or two liquid sheets that have the same characteristics as a solid confinement system whilst having the added benefit of easy installation and allowing improved access for maintenance in the confined area.
  • the present invention aims to generate one or more continuous liquid sheets (or water curtains). Furthermore, the invention is intended to be able to adjust the thickness and spacing of the liquid sheets as required, in order to provide a degree of additional varying attenuation as required, and facilitating access for maintenance.
  • an aim of the device is to receive the fall/cascade of the liquid sheet by limiting the creation and spread of noise toward the external environment.
  • the invention thus aims at proposing a device possessing advantages of easy installation, the possibility of maintenance without any constraints, all whilst assuring the method of confining the harmful acoustics of the environment and the noise created by the device.
  • a module for a device generating at least one water curtain aimed at confining an area of space or for a cooling tower including:
  • the module can also have at least one holding zone, mounted downstream of the water supply and upstream of the convergence zone; the holding zone includes one or several flexible expandable grids and/or an expandable porous material and/or a material including a multitude of flexible channels of thin walls.
  • the convergence zone can have two walls where the extensions below form the two walls of the nozzle.
  • the holding zone can have two walls where the extensions below form the two walls of the convergence zone.
  • One of the nozzle walls can be mobile and the other fixed, and the module can have the possibility to move the mobile wall.
  • the module can have two convergence zones and two nozzles, one of the walls of each nozzle is mobile and the other fixed, and the module can have a possibility of changing the distance between the two fixed walls of both nozzles.
  • the module can have means for attaching it to other modules, mounted on the side extremities of the module, and possibly a reception system for isolation partitions mounted on the side extremities of the module and suitable to meet the cut-off walls to isolate the convergence zone and possibly the module's holding zone of the adjacent modules.
  • a module for a device generating at least one water curtain aimed at confining an area of space for a cooling tower, including at least one module as previously described.
  • the device can also include a reception system for at least one water curtain, formed by a longitudinal body with a length equal to the length of the water curtain, the body of which includes:
  • the slot can be defined by a first vertical wall and a second wall allowing the flow along the aforementioned second wall of the water curtain falling on it, and supply water towards the first wall.
  • two water curtains are formed and the water curtain falling on the second wall intercepts the other water curtain during its delivery to the first wall.
  • Figure 1 represents, schematically, a module of the device generating at least one liquid sheet for the acoustic, thermal and particle confinement in the environment represented, or for the cooling of a cooling tower.
  • the device generating at least one liquid sheet is formed by assembling one or more modules such as those represented in figures 1 , 2 or 3 .
  • a module is a set that includes one subset generating a single fixed sheet with variable thickness and a second subset generating a mobile sheet of variable thickness, the adjustment of the spacing between the sheets can be performed completely independently and the adjustment of their thicknesses by an annexed jack system, which automatically or manually moves both subsets together.
  • the connecting of these different modules is achieved by means of fixation or clamping provided for this purpose.
  • the seal is assured by a static seal positioned in a groove that is machined into the fastening system; another fastening system is used to fix it to an upstream or downstream module.
  • An injection system for an air gap can be integrated into the generating device where the aim would be to condition the air gap present between the two liquid sheets in order to make the latter more stable and as continuous as possible.
  • the module could also include means for receiving the isolation partitions or isolation valves. When the supply of liquid to the module stops, these isolation valves close and that prevents any liquid from entering into the isolated module, this creates a break in the continuity of the liquid sheet on the isolated module, also guarantying the dry passage of a solid body towards or outside of the confined space.
  • the cross-sectional view of the module according to the first method of implementation represented on figure 1 includes, for the first subset generating a fixed sheet:
  • variable length 4 can integrate an air vent 14 in order to regulate the air pressure inside the first subset generating a fixed sheet and allows the variation of the distance between the two upper walls 2 and 3, namely when the thickness of the liquid sheet varies.
  • the first subset generating a fixed sheet can also include:
  • the first subset generating a fixed sheet includes a nozzle for the build up of the liquid sheet.
  • the nozzle includes:
  • the first subset generating a fixed sheet includes a conditioning system for liquid with a variable thickness 11, marked with dots in figure 1 , and fixed to the two upper walls 2 and 3, which aims to direct and condition the flow of liquid to provide optimal conditions for generating the first continuous liquid sheet.
  • the module also includes a second subset for the generation of a mobile sheet.
  • the second subset includes:
  • variable length 4' can integrate an air vent 14' in order to regulate the air pressure inside the first subset generating a fixed sheet and allows the variation of the distance between the two upper walls 2' and 3', namely when the thickness of the liquid sheet varies.
  • the second subset generating a mobile sheet can also include:
  • the second subset generating a mobile sheet includes a nozzle for the build up of the liquid sheet.
  • the nozzle includes:
  • the second subset generating a mobile sheet includes a conditioning system for liquid with a variable thickness 11', marked with dots in figure 1 , and fixed to the two upper walls 2' and 3', which aims to direct and condition the flow of liquid to provide optimal conditions for generating the first continuous liquid sheet.
  • the adjustment of the thickness of both liquid sheets can be done completely independently from each other, either by regulating the height of the liquid on the inside of both subsets generating a liquid sheet by controlling the two liquid supplies independently, or by an annexed jack system 12 and 12' that automatically or manually moves all mobile walls (made up of walls 3, 6, 8, 10 on one side and 3', 6', 8', 10' on the other side), in the same direction, of both subsets generating a sheet.
  • the adjustment of the spacing between the sheets can be done completely independently from the adjustment of their thicknesses by an annexed jack system 13 that automatically or manually moves, in the same direction, both subsets generating a sheet.
  • the discontinued arrows on figure 1 represent the path taken by the liquid inside each subset generating liquid sheets.
  • the cross-sectional view of the module according to the second method of implementation represented on figure 2 includes, for the first subset generating a fixed sheet:
  • the first subset generating a fixed sheet includes a nozzle for the build up of the liquid sheet.
  • the nozzle includes:
  • the first subset generating a fixed sheet includes a conditioning system for liquid with a variable thickness 30, marked with dots in figure 2 , and fixed to the two upper walls 22 and 23, which aims to direct and condition the flow of liquid to provide optimal conditions for generating the first continuous liquid sheet.
  • the module also includes a second subset for the generation of a mobile sheet.
  • the second subset includes:
  • the second subset generating a mobile sheet includes a nozzle for the build up of the liquid sheet.
  • the nozzle includes:
  • the second subset generating a mobile sheet includes a conditioning system for liquid with a variable thickness 30', marked with dots in figure 2 , and fixed to the two upper walls 22' and 23', which aims to direct and condition the flow of liquid to provide optimal conditions for generating the first continuous liquid sheet.
  • a connection of variable width 32 connects the two upper walls 22 and 22' and can integrate an air vent 32' in order to regulate the air pressure in the inside of the module.
  • the adjustment of the thickness of both liquid sheets is managed dependently this time because the second mobile liquid sheet is only created once the first sheet generated by the first fixed subset is at its maximum thickness, either by regulating the height of the liquid on the inside of the first subset by supplying liquid to the module, or by an annexed jack system 33 that automatically or manually moves all the mobile walls of the first subset (made up of elements 23, 25, 27, 29).
  • the thickness of the second sheet is set using an annexed jack system 34 which automatically or manually moves all the mobile walls of the second subset (made up of elements 23', 25', 27', 29').
  • the adjustment of the spacing between the sheets is performed completely independently from the adjustment of the thickness of the sheets, by an annexed jack system 35 that automatically or manually moves both subsets.
  • the cross-sectional view of the module according to the third method of implementation represented on figure 3 includes, for the first subset generating a fixed sheet:
  • the first subset generating a fixed sheet includes a nozzle for the formation of the liquid sheet.
  • the nozzle includes:
  • the first subset generating a fixed sheet includes a conditioning system for liquid with a variable thickness 50, marked with dots in figure 3 , and fixed to the two upper walls 42 and 43, which aims to direct and condition the flow of liquid to provide optimal conditions for generating the first continuous liquid sheet.
  • the module also includes a second subset for the generation of a mobile sheet.
  • the second subset has a supply slot of variable spacing 52, supplying liquid to the second subset generating a mobile sheet via the bottom from the first subset, once the latter has reached the position generating the fixed sheet at the maximum thickness.
  • the height of this slot supplying the second subset must be in the same order of magnitude as the section crossed by the liquid in the second subset generating a liquid sheet in order to avoid a dead zone and poor distribution of liquid in the device and so the edges of the slot have a form designed so the flow entering into the second subset generating a sheet is not disrupted.
  • the second subset includes:
  • the adjustment of the thickness of both liquid sheets is managed dependently this time because the second mobile liquid sheet is only created once the first sheet generated by the first fixed subset is at its maximum thickness, either by regulating the height of the liquid on the inside of the first subset by supplying liquid to the module, or by an annexed jack system 57 that automatically or manually moves all the mobile walls (made up of elements 55, 53, 51, 45, 35, 47, 49) of both subsets generating sheets.
  • the adjustment of the spacing between the sheets is also dependent of the adjustment of the thickness of the second liquid sheet because the overflow system will form a second liquid sheet where the thickness is in accordance to the flow. This flow is also the parameter that allows the protection of the second liquid sheet more or less far from the edge of the horizontal surface of the overflow 55.
  • the liquid conditioner integrated in the subset generating at least one liquid sheet can include the arrangement of different components susceptible to be used in a conditioner of liquid flow.
  • This conditioner can include:
  • the entire conditioning system must be made with the material that can be stretched in the direction of the cross-section of the subset, so it can be adapted to the dimensional variation between the two walls during the setting of the thickness of the liquid sheets.
  • Figure 4 shows the shape of the convergences to employ to make the transition between the entry of width l e and the exit of l s with a convergence of length X. This transition must be done in a progressive manner and with tangents parallel to the convergence axis in entry and exit.
  • Figure 5 shows a means of receiving one or two falling liquid sheets, which limits the creation and transmission of noise towards the space to protect.
  • the principle is that at least one external liquid sheet is received by running along the curved surface of the first reception wall 100, this allows acoustic isolation.
  • the external liquid sheet is received in such a way that the entrance in contact with the surface curve of the first reception wall 100 is as soft as possible: the slope of attack 200, angle ⁇ in relation to the vertical, of the curved surface of the first reception wall 100 is nearly vertical.
  • the slope of the curve of the first reception wall 100 is smooth and gradually modified to the point of detachment of the liquid sheet outside the curved surface of the first reception wall 100: a trailing edge 300 is planned at the end of the curved surface of the first reception wall 100.
  • the trailing edge 300 is rounded in order to prevent a depression zone susceptible to disrupting the flow upstream.
  • the system will allow the connection of the internal and external liquid sheets and the contact of those - to avoid increasing the number of noise sources. This is done after the detachment of the external liquid sheet from the curved surface of the first reception wall 100. As such, the zone where the internal and external liquid sheets meet does not disturb the seal of the external liquid sheet upstream. The location of the meeting zone depends on the direction (defined by angle ⁇ between the vertical and the trailing edge) and the speed of the external liquid sheet after detachment.
  • a curved routing surface 500 extending a second partition wall at the opening of the reception system, has an angle of attack 400 made by a slight recess adapted to the direction of the liquid met, which means no noise is generated when the speed of the falling liquid sheet is broken.
  • the liquid sheet Once contact has been made with the liquid sheet, it is then delivered to the recuperation chamber 800 via the curved surface of the smooth flow 500 which allows the conservation of speed of the liquid to avoid generating noise in this zone.
  • the curved surface of delivery 500 is finalized by a trailing edge 700 which helps to maintain a regular flow of the liquid sheet until the discharge in the chamber 800.
  • Chamber 800 is the zone where noise can be created by the agitation generated from the arrival of the liquid in chamber 800. Chamber 800 is placed in depth and offset from the axis of the fall of the liquid sheets. The venting of the chamber 800 is obtained used an air vent 600. This venting allows the flow of liquid to be received on a free surface. All reception systems are thus at atmospheric pressure and are not subject to pressure variations that can disrupt or change the geometry of the sheets' flow. In the reception system, an evacuation adapted to the entering flow must be envisaged at the level of the chamber to assure its correct functioning.
  • the reception system is capable of receiving liquid sheets of variable geometry and spacing.
  • the necessary conditions of this, and not changing the precise functioning, are as follows:
  • the reception system must be constructed or installed on floor level or possibly a block independent of the floor.
