Definitions

  • the invention relates to a screen installation for a traffic route, comprising a vertical carrier and a device connected to the carrier with collecting material or cleaning material for the removal of particles, such as fine dust, from ambient air.
  • particles of this type can adversely affect public health, particularly in the case of persons located in the immediate vicinity of a road or railway.
  • a screen installation of this type is known from WO 2007/100254 .
  • particles such as smut and fine dust are removed from the air by means of an electrically charged surface.
  • the electrical charge can be obtained by creating a static electrical field with the aid of a generator. Under the influence of this electrical charge, particles contained in the air are deposited on the electrically charged parts concerned.
  • the particle-laden air which originates, for example, from a roadway or railway line can thus be cleaned.
  • the electrical charge is applied to metal parts provided specifically for this purpose, such as in the form of a grid, projections and the like. Electret material can also be used. A dielectric medium of this type is continuously electrified and requires no generator to create the electrical field. The electrically charged parts are normally disposed in a distributed manner on and are integrated into the vertical carrier. This means that the carrier is designed specifically for this purpose, and in this sense differs from other carriers such as those in the form of a standard noise barrier or standard central reservation protection.
  • the object of the invention is therefore to produce a screen installation of the aforementioned type which has a simpler and more flexible design.
  • the device comprises at least one module which is provided with the collecting material or the cleaning means, and that detachable fixing means are provided by means of which the module and the carrier interwork detachably with one another.
  • the screen installation can be designed in a simple manner, and in a manner which is geared towards local circumstances.
  • the module has the cleaning means or collecting means required for this purpose.
  • more or fewer modules of this type with electrostatic material and/or possibly filters can be disposed.
  • the module may comprise a housing on which the collecting material is provided, said housing interworking with the fixing means.
  • a housing of this type can protect the cleaning material against the effects of weather, such as wind and rain. Here, it must be ensured that the contaminated air can be brought into contact with the electrostatically charged material. If the electrostatic material is freely accessible on the outside of the housing and is therefore not entirely enclosed, the contaminated air can flow along it, whereby a cleaning effect then simultaneously occurs.
  • filter material can be used, such as fibrous material and non-woven material.
  • the housing defines a flow path for air mixed with particles, the collecting material being located along or in said flow path.
  • the contaminated air must flow through the housing, which can be achieved in different ways, as will be explained below.
  • the flow path can extend between the carrier and the housing.
  • the housing may comprise only a single panel located at a distance from the carrier, said panel having fixing means, such as hooking means, by means of which the panel is suspended from the carrier.
  • a flow channel for the contaminated air is thus formed between the carrier and the panel of the housing which is suspended from the carrier.
  • a very simple housing is thus obtained, which has a low cost price and can be attached in a simple manner at the required location along the carrier.
  • the housing may comprise two panels located opposite one another, between which the flow path extends. These two panels located opposite one another may be attached to one another by means of transverse panels, in such a way that a laterally enclosed flow channel is obtained.
  • the module can be disposed on different types of carrier.
  • a carrier which comprises two walls enclosing an intermediate space, of which at least one is permeable to air with particles, and the module is accommodated in this intermediate space.
  • a carrier of this type may have a porous wall facing the traffic route, which may extend to the ground or base. It is also possible to design both walls as porous. The contaminated air is then forced to flow through the porous wall, whereafter it flows through the module in the intermediate space.
  • the porous wall may, for example, contain a catalyst such as titanium dioxide for the conversion of NOx.
  • the contaminated air must flow through the housing. This may occur under the influence of the vortices which are generated by the passing traffic and the wind. Additionally or alternatively, a flow of this type may be encouraged if the upper side of the housing defines a discharge opening and a cover is located at a distance above the discharge opening. A reduction in pressure occurs between the discharge opening and the cover if wind strikes a cover along the opening. The suction which is thereby created in the flow channel produces a draught which results in the introduction of contaminated air.
  • a filter can be used in addition to or instead of the electrostatically acting cleaning means.
  • the underside of the housing may comprise an inlet which is covered by a filter.
  • Other positions for the filter are also possible, for example higher in the flow channel.
  • the collecting material may comprise an electret, i.e. a material with a permanent charge.
  • the collecting material may also be statically charged under the influence of a generator.
  • the collecting material may be designed accordingly in different ways. It may, for example, comprise a gauze, or projections which are connected to a current source. Alternatively, the collecting material may be in the form of a sheet or strip and may comprise an electret.
  • the invention furthermore relates, in combination, to a traffic route and a screen installation extending along the traffic route, as described above.
  • the carrier may be a noise barrier extending along the traffic route, a central reservation protection, a wall of a building and the like.
  • the invention relates to a module for a screen installation as described above.
  • the term "module” is understood to refer to a unit which is self-supporting. This self-supporting unit may offer internal or external space to a collecting device, by means of which particles can be removed from contaminated air. A module of this type may also have gripping points on which hoisting means can grip for the installation, removal or replacement of the module. The process of removal of the particles may be based on electrostatic attraction, and/or may involve the step of filtering.
  • the carrier may be a noise barrier, a central reservation protection, a wall of a building, or a wall of a tunnel.
  • the detachable fixing means by means of which the module is attached to the carrier may be designed in many different ways.
  • fixing means may comprise screw connections, connections by means of corresponding forms such as dovetail joints, mortise and tenon joints and the like.
  • the module housing may be single-walled or double-walled.
  • the housing may be enclosed all round, insofar as a continuous channel is also provided through which the contaminated air can flow.
  • the housing may comprise any suitable material, such as metal, plastic, wood and combinations thereof.
  • Electrostatic material is understood to refer to a material which is designed to generate a static electrical field. This may involve, for example, conductive material formed in such a way that electrical field lines can be concentrated, as a result of which deposition of charged particles can be expected. This may involve, for example, gauze, tapered elements and the like.
  • the screen installation 1 is installed along a traffic route 2 with a safety barrier 6.
  • the traffic 3 moving along said route emits exhaust gases 4, which combine with the air 5.
  • the screen installation 1 is composed of a wall 7 facing the traffic route and a wall 8 located behind it, facing away from the traffic route 2.
  • An intermediate space or flow space 9 is located between these walls.
  • On the upper edge of the walls 7, 8, the intermediate space is connected to the open air via the passages 10 which are located between the upper edge of the walls 7, 8 and the cover 11. This cover is supported at a distance above the walls 7, 8 by means of supports 12.
  • the wall 7 facing the traffic route 2 has a permeable structure as a result of the fact that it is composed of substances 13, for example lava stones, which are accommodated in the gabions 14.
  • These gabions 14 comprise metal wire with a mesh width which is such that the substances 13 are retained in the gabions 14.
  • Jagged-shaped fissures 15, via which the air can enter the intermediate space 9 over the entire surface of the permeable wall 7, are present between the substances 13. In particular, this involves the component 6 of the air 5 which is directed transversely towards the screen installation 1.
  • the surface of the permeable wall 7 facing the traffic route 2 is provided with titanium dioxide 16 in such a way that, under the influence of light, a catalytic conversion of NOx is achieved. Coarser particles are absorbed in the jagged-shaped fissures 21 of the permeable wall 7.
  • Modules 22 containing sheets, strips or wires 17 made of electrostatic or electret material are present in the intermediate space 9.
  • Each of the modules comprises a housing 23 with two panels 24, on the upper side of which the flanges 25 are located.
  • the underside of the housing has an inlet 26 which is covered by a filter 27, providing access to the flow channel 30.
  • the air which has entered the intermediate space 9 can now be further cleaned if it flows up via the inlet 26 and the filter 27 along the electrostatic or electret material 17 under the influence of the funnelling effect which occurs between both walls 7, 8 and between the panels 23, and finally the air flows out through the discharge opening 31 of the housing. Particles with a dipole character and/or charged particles become attached to the electrostatic or electret material.
  • the number can be varied, for example a single sheet or more than two sheets.
  • the electrostatic or electret material does not have to be in the form of a sheet; electret material in the form of a strip or wire can be envisaged as an alternative.
  • the electrostatic or electret material does not have to hang in the module, but can also be attached to the outside of the module or against the rear wall 8. Air which flows into the higher parts of the porous wall 7 is first forced to flow down along the electrostatic means located on the outside of the housing, whereby a part of the contamination is already removed. The air can then flow up in the manner described above. The air which finally emerges on the upper edge from the screen installation is thus partially cleaned of NOx and fine dust.
  • the screen installation 1 has a base 18, by means of which the screen installation is embedded in the side-strip 19 along the traffic route 2.
  • the permeable wall 7 extends fully to this base 18. The air is thereby forced to flow through the permeable wall 7, to achieve a maximum cleaning effect.
  • a cutting may possibly be provided near the underside of the permeable wall 7.
  • the internal space 9 is divided into compartments by the partitions 20 which extend transversely at regular intervals from one another between the walls 7, 8. However, this is not necessary.
  • the modules can be installed in a simple manner in the intermediate space 9 and can be fitted with the flanges. This can be carried out, for example, with a hoisting crane (not shown), which can grip on the hoisting eyes 31.
  • a hoisting crane (not shown), which can grip on the hoisting eyes 31.
  • the complete modules can be removed and replaced with new modules. It is not necessary to dispose the modules at specific fixed intervals from one another. Depending on the expected level of contamination, more or fewer modules can be disposed per length unit along the traffic route. In this connection, it is also possible to suspend more or less electret material from the modules.
  • a module 22 which has only one single panel 23, and is suspended against the wall 8 by means of the flange 25, on the end of which the hook 28 is located.
  • a support 29 is provided to offer support against the wall 8.
  • the flow channel 30 is now defined between the surface 21 of the wall 8 and the panel 23.
  • the upper side has a discharge opening 31, at a distance above which the cover is 11 is mounted.
