Abstract

PROBLEM TO BE SOLVED: To provide a module for a device generating at least one water curtain and a corresponding device.SOLUTION: The present application concerns a module for a device generating at least one water curtain aimed at confining an area of space or for a cooling tower, including: at least one water supply; at least one convergence zone mounted downstream of a holding zone; and at least one nozzle mounted downstream of the convergence zone and made of two parallel walls, the walls being equal in length to the module and separated by a distance defining the thickness of the water curtain. The application also concerns a device generating at least one water curtain including a module defined in advance.

Description

  The present invention relates to a module and a corresponding device for a device for generating a curtain for either confinement of a space area or a cooling tower.

  The present invention provides a water curtain (or liquid sheet) to confine an environment where various types of pollution / pollution such as sound, heat, gas and particles are present and can occur simultaneously or singly or for cooling towers. ). This device can deal with one or all four of the aforementioned contamination / pollutions. The containment of these pollution / pollution sources is a problem frequently encountered not only in industrial situations but also in public situations. The present invention can be used to contain any type of machine that produces such contamination / pollution, such as boilers, motors, pumps, turbines, and the like.

  In many industries, safety standards for noise pollution limit the level of noise in areas where people live. Known solutions for limiting noise transmission include installing acoustic screens or panels around the noisy environment.

  With respect to air pollution, the law mandates the placement of screens around affected areas to limit the spread of gaseous, liquid and solid pollution to the environment to be protected. In other cases, for regulatory or technical reasons, it is sometimes necessary to discharge some of the heat generated by the equipment. In general, it is common to use a material that traps noise pollution in the form of a solid panel that includes an absorbing layer (a layer with various characteristics) to disrupt sound waves. These signs also allow the containment of gas contamination, particle contamination and thermal pollution, as described in document US Pat. No. 7,604,695 (B2). Nevertheless, the presence of openings in the solid panel affects the quality of acoustic and thermal separation, often limiting the number and surface of the solid panels. The use of these panels to obtain a closed area creates difficulties in accessing the area, for example for repair and maintenance of confined equipment.

  There are also simple liquid wall gas decontamination systems and chemical decontamination systems, which are incompatible with acoustic elements. Document FR2641201 contains a double water curtain that confines a spatial region that is susceptible to air pollution but does not guarantee the continuity of the liquid sheet proposed by the present invention, only by creating a simple curtain without a closed profile. Is disclosed.

  The present invention accepts one or two liquid sheets that allow the confinement of the contaminated / polluting environment to be maintained without causing the polluting / polluting or moving it to the environment to be protected. To mention.

  There is a high pressure water jet receptor that cuts sheet metal. An example of this system is shown in document US Pat. No. 3,730,040. This device is designed to absorb the energy of water in order to reduce the generated noise. However, the application and characteristics of the liquid and system are not in the same situation as the present invention.

  A water-cooled receiver such as that described in document US Pat. No. 4,130,613 allows for the collection of water falling from the cooling tower and the prevention of noise due to the outwardly spreading waterfall. However, the scope of its application and the essential design of the system are not the same as in the present invention.

  The receiving device for free-falling liquid described in document US Pat. No. 4,385,010 allows the reduction or removal of the vertical velocity of the liquid, but does not allow the limitation of noise pollution.

  There is an active system for reducing noise, such as the device described in document US Pat. No. 5,394,376, which is intended to reduce or eliminate noise sensors, signal processing systems and vibrations caused by liquid flow. And a discharge system for phase shift pressure oscillation. Other systems include creating opposing noise and eliminating the noise caused by the liquid. However, techniques for reducing active noise are generally complex and expensive.

US Pat. No. 7,604,695

  The present invention has the added benefit of easy installation and allows for improved access for maintenance within the containment area, while at the same time one or two liquids having the same characteristics as the solid containment system It has a sheet receptacle.

  The present invention is directed to producing one or more continuous liquid sheets (or water curtains). Furthermore, the present invention adjusts the thickness and spacing of the liquid sheet as necessary to achieve some additional variable attenuation as needed, and facilitates access for maintenance. It aims to be able to.

  Furthermore, the purpose of the device is to accept a fall / cascade flow of liquid sheets by limiting the generation of noise and its spread to the external environment. The present invention thus proposes a device which has the advantage of always being easy to install and possible to maintain without any restrictions, while at the same time ensuring a way to confine environmental harmful sounds and noise generated by the device. The purpose is that.

  Thanks to the present invention, it is possible to obtain a device that does not use a permanent solid wall and thus allows a person to more easily access the required area. This means a reduction in the number of elements that must be removed to obtain a lower density structure and access.

  The module can also have at least one holding area attached downstream of the water supply and upstream of the convergence area. The holding area comprises a material comprising one or several flexible expandable grids and / or expandable porous materials and / or multiple flexible thin wall channels.

  The convergence zone can have two walls, with the lower extension forming the two walls of the nozzle.

  The holding area can have two walls whose lower extension forms two walls of the convergence area.

  One of the nozzle walls can be movable and the other fixed, and the module can have the possibility to move the movable wall.

  The module can have two convergence areas and two nozzles, one of the walls of each nozzle being movable and the other fixed, so that the module can measure the distance between the two fixed walls of both nozzles. Can have the possibility to change.

  The module has means for attaching the module to other modules mounted on the side edge of the module, and possibly the module holding area of the adjacent module mounted on the side edge of the module and possibly the converging area And a receiving system for the separating partition suitable for adapting the blocking wall to separate from.

  In one aspect, there is also proposed a module for an apparatus intended for confining a spatial region or generating at least one water curtain for a cooling tower, comprising at least one module as described above.

The apparatus can also include a receiving system for at least one water curtain formed by a longitudinal body having a length equal to the length of the water curtain, the body comprising:
-A longitudinal opening on the upper surface of the body into which the water curtain enters;
A chamber attached to the inside of the body for collecting and supplying water from the water curtain;
-A slot for feeding water entering by a longitudinal opening towards the collection supply chamber.

  The slot can be defined by a first vertical wall and a second wall, allowing flow along the aforementioned second wall of the water curtain to fall onto the slot and towards the first wall. Makes it possible to supply water.

  Optionally, two water curtains are formed and the water curtain falling on the second wall blocks the other water curtain during its delivery to the first wall.

  It is also contemplated that the module can include means for receiving a separation septum or shut-off valve.

  The adjustment of the thickness of both liquid sheets can be achieved by adjusting the liquid height inside both subsets generating the liquid sheet by independently controlling the two liquid supplies, or both subsets generating the sheet. All the movable walls (made of walls 3, 6, 8, 10 on one side and walls 3 ', 6', 8 ', 10' on the other side) are automatically or manually moved in the same direction Either of the jack systems 12 and 12 'can be done completely independently of each other.

  Similarly, the adjustment of the spacing between sheets can be done completely independently of the adjustment of the thickness of the sheet by means of an attached jack system 13 that moves both subsets generating the sheet automatically or manually in the same direction. The discontinuous arrows in FIG. 1 indicate the path taken by the liquid inside each subset that produces the liquid sheet.

The cross-sectional view of the module according to the second implementation method shown in FIG. 2 is for the first subset producing the fixed sheet:

  The second subset producing the movable sheet is indicated by dots in FIG. 2 and is an adjustment system for a liquid having a variable thickness 30 ′, which is fixed to the two top walls 22 ′ and 23 ′. The adjustment system is directed to directing and adjusting the liquid flow to provide an optimal condition for producing a second continuous liquid sheet.

  When the variable sized surface 31 connected to the first subset of movable upper walls 23 and the second subset of movable upper walls 23 ′ reaches a position where the first subset produces the maximum thickness of the fixed sheet. Liquid is pumped from the first subset that generates the fixed sheet to the second subset that generates the movable sheet.

  A variable width 32 connection connects the two top walls 22 and 22 ', and a vent 32' can be integrated to regulate the air pressure inside the module.

  Adjusting the thickness of both liquid sheets provides liquid to the module because the first sheet produced by the first fixed subset will only produce a second movable liquid sheet when its maximum thickness is reached. Adjusting the height of the liquid inside the first subset, or automatically or manually moving all the movable walls of the first subset (made of elements 23, 25, 27, 29) This time, it is subordinately managed by either of the attached jack systems 33. The thickness of the second sheet is determined using an attached jack system 34 that automatically or manually moves all the movable walls of the second subset (made of elements 23 ', 25', 27 ', 29'). Is set.

  However, the adjustment of the spacing between the sheets is carried out completely independently of the adjustment of the thickness of the sheets by means of an attached jack system 35 that moves both subsets automatically or manually.

The cross-sectional view of the module according to the third method of implementation shown in FIG. 3 is for the first subset producing the fixed sheet:

A movable inlet wall at the vertical nozzle 47 attached to the lower extension of the second movable converging wall 45 and parallel to the fixed inlet wall of the vertical nozzle 46;
A fixed wall that opens from a nozzle outlet 48 in the extension of the fixed inlet wall of the vertical nozzle 46;
A movable wall that opens from a nozzle outlet 49 attached to an extension of the movable inlet wall of the vertical nozzle 47.

  A first subset for generating a fixed sheet includes an adjustment system for a liquid having a variable thickness 50, indicated by dots in FIG. 3 and fixed to two top walls 42 and 43, The conditioning system is intended to direct and regulate the liquid flow to provide an optimal condition for producing the first continuous liquid sheet.

  The module also includes a second subset that generates the movable seat. The second subset has feed slots with variable spacing 52, and when the first subset reaches a position that produces a fixed sheet of maximum thickness, it produces a movable sheet from the first subset through the bottom. Supply liquid to the second subset. The height of this slot feeding the second subset is to avoid blind spots and under-distribution of liquid in the apparatus and the flow of the slot edges entering the second subset producing the sheet. Must be in the same order as the portion traversed by the liquid in the second subset producing the liquid sheet so that it has a shape designed to be uninterrupted.

The second subset is
A movable upper wall 53;
Attached to the extension of the converging wall 45, whose shape is defined by the curvature shown in FIG. 4, involved in the redirection of the flow and the filling of the second subset at best The other converging walls 51,
A second simplified system for regulating the liquid 54, attached to both upper walls 43 and 53 and powered by the liquid circulating between the walls 43 and 51;
A movable upper wall 53 of the module attached to the upper extension of the converging wall 51;
A horizontal plane attached to the other tip of the movable upper wall 53 that functions as a drain and is sized to form a second liquid sheet having the desired characteristics; 55,
-A fixed long wall 56 depending on the two upper walls 42 and 43.

  Since the first sheet produced by the first fixed subset is at its maximum thickness, only a second movable liquid sheet is created, so that by supplying liquid to the module, the interior of the first subset Of an attached jack system 57 that adjusts the height of the liquid or moves all the movable walls (made of elements 55, 53, 51, 45, 47, 49) of both subsets automatically or manually to produce a sheet Either way, the adjustment of the thickness of both liquid sheets is managed in a subordinate manner this time. Similarly, adjusting the spacing between sheets is also dependent on adjusting the thickness of the second liquid sheet because the drainage system forms a second liquid sheet whose thickness is based on flow. Also, this flow is a parameter that allows protection of the second liquid sheet that is more or less far from the edge of the horizontal surface of the drain port 55.

Liquid regulators integrated into a subset that produces at least one liquid sheet can include various component arrangements that are amenable to use in liquid flow regulators. This regulator
A first flexible grid and a second flexible grid, which can be stretched in the direction of the cross section of the subset, with a hole density adapted to ensure a good distribution of the liquid from the supply system; ,
A flexible porous material that can be stretched in the direction of a subset of cross-sections in the form of a foam, whose density and porosity have been optimized to reduce the velocity of the traversing liquid; This flexible porous medium is sandwiched between two flexible grids and can be stretched in the direction of the cross section of the subset, thereby ensuring separation from the support and other elements of the regulator. A flexible porous material;
-Provides sufficient area of the upstream flexible porous medium and has the role of directing the liquid flow in parallel towards the outlet of the regulator before being sent downstream towards the convergence of the subset producing the sheet And systems including multiple flexible thin-walled tubes, such as honeycomb structures and the like.

  The entire adjustment system is made using a material that can be stretched in the direction of the cross section of the subset so that the adjustment system can accommodate dimensional variations between the two walls during the setting of the thickness of the liquid sheet. There must be.

FIG. 4 shows a shape of convergence that employs creating a transition having a convergence of length X between an inlet of width l _e and an outlet of l _s . This transition must be made innovatively with tangents parallel to the inlet and outlet convergence axes. The relationship between the distance y (between the generator point on the convergence curve and the central axis) and the generator height x is:
When a beta = x / X and _{2δ = l s -l e, y} = Kδ (1-β 1.5) 2 + l s / 2
It is a point to obey.
Here, K is a constant that affects the shape. Considering the former, this equation leaves great freedom in the dimensions of convergence width and length.

  FIG. 5 shows a means for receiving one or two falling liquid sheets, which limits the generation of noise and its transmission to the space to be protected. The principle is that at least one outer liquid sheet is received by flowing along the curved surface of the first receiving wall 100, which allows acoustic separation.

  In order to ensure this separation, the outer liquid sheet is received such that the entry in contact with the curvature of the surface of the first receiving wall 100 is as quiet as possible. The slope of the attack 200, which is an angle α with respect to the vertical, of the curved surface of the first receiving wall 100 is almost vertical. In order to overcome sudden fluctuations in pressure and to maintain contact with the curved surface of the first receiving wall 100, the slope of the first receiving wall 100 is smooth and the first receiving wall 100 is curved. Gradually corrected to the separation point of the liquid sheet outside the surface. A trailing edge 300 is planned at the end of the curved surface of the first receiving wall 100. The trailing edge 300 is rounded to prevent the depressed area from easily interrupting upstream flow.

  The simple fact that there is a constant contact between the outer liquid sheet and the curved surface of the first receiving wall ensures acoustic separation of the protected area.

  If another falling inner liquid sheet needs to be received, the system allows the inner and outer liquid sheets to be connected and contacted to avoid an increase in the number of noise sources. This is done after the outer liquid sheet has separated from the curved surface of the first receiving wall 100. Thus, the area where the inner and outer liquid sheets meet does not interfere with the sealing of the upstream outer liquid sheet. The location of the encounter area depends on the direction after separation (determined by the angle β between the vertical and the trailing edge) and the velocity of the outer liquid sheet.

  After this contact, a single liquid sheet is considered to have an initial direction based on the vertical angle γ. The curved path surface 500 that extends the second separation wall to the opening of the receiving system has an angle of attack 400 made by a slight recess adapted to the direction of the liquid encountered, When the speed of the falling liquid sheet is disrupted, it means that no noise is generated.

  Once in contact with the liquid sheet, it is then delivered to the recovery chamber 800 via a uniform flow curved surface 500 that allows the liquid velocity to be maintained and avoids the generation of noise in this area. The delivery curved surface 500 is terminated by a trailing edge 700 that helps maintain a constant flow of the liquid sheet until ejection in the chamber 800.

  The chamber 800 is an area where noise may be generated by agitation caused by the arrival of liquid in the chamber 800. The chamber 800 is deeply arranged and is offset from the axis of drop of the liquid sheet. Ventilation of the chamber 800 is obtained using the vent 600. This ventilation allows a liquid flow to be received on the free surface. In this way, all receiving systems are at atmospheric pressure and are not affected by pressure fluctuations that can destroy or alter the shape of the sheet flow. In the receiving system, an exhaust adapted to the incoming flow must be envisioned at the chamber level to ensure its correct functioning.

The receiving system can receive liquid sheets of various shapes and spacings. The requirement for this and not changing the precise function is as follows:
The outer surface area of the outer liquid sheet must be fixed for the correct functioning of the acoustic seal;
The combined thickness of both the inner and outer liquid sheets and the gap between both the inner and outer liquid sheets must be less than or equal to the width of the inlet to the receiving system;
-The falling inner liquid sheet must not come into contact with the curved surface of the first receiving wall 100.

  The receiving system must be constructed or installed on a floor height or possibly a block independent of the floor surface.
