    Depolluting construction.
    TECHNICAL AREA
    The present description relates to depolluting constructions.
    More particularly, the present description
    concerned a depolluting construction including a blanket who includes:- a water permeable filter layer and to the air, - a upper wall which is permeable to 1 water and looks and which supports the filter layer,
    a lower wall which is arranged under the upper wall and which is impermeable to water, the lower wall delimiting with the upper wall a plenum, at least one forced ventilation device adapted to draw air into the plenum through the filter layer and the top wall.
    TECHNOLOGICAL BACKGROUND
    Document WO2010 / 128252 describes an example of a depolluting roof, which in particular has the disadvantage of comprising a relatively complex ventilation device for sucking air through the filtering layer.
    OBJECTS AND SUMMARY
    The present description aims in particular to overcome this drawback.
    To this end, in a building of the aforementioned type, the forced ventilation device comprises:
    a watertight chimney extending in the plenum between a lower end tightly connected to the lower wall and an upper end opening into the plenum, the lower end of the chimney communicating with the atmosphere under the wall lower, and a fan disposed in said chimney, a cap being disposed above the chimney, said cap being impermeable and shaped to prevent water passing through the filtering layer and the upper wall falling into the chimney.
    In this way, the structure of the suction device is simplified while ensuring that the presence of water does not disturb the operation of the forced ventilation device.
    In various embodiments of the depolluting construction, one can optionally have recourse to one and / or the other of the following provisions:
    the filter layer is a plant layer;
    the cover is substantially horizontal (for example, horizontal or inclined less than 10 degrees relative to a horizontal plane);
    the hat has a top covering the chimney and a peripheral rim extending downwards from a periphery of the top of the hat;
    the top of the hat belongs to the upper wall;
    the depolluting construction also includes a water discharge conduit opening into the plenum;
    the depolluting construction further comprises an electronic central unit which is connected to the fan and which is adapted to control said fan;
    the depolluting construction further comprises at least one humidity sensor adapted to measure a humidity in the filtering layer, and the electronic central unit is adapted to control the fan so that the fan does not operate when the measured humidity exceeds a first predetermined threshold;
    the fan is adapted to measure and communicate to the electronic central unit at least one operating parameter of said fan and the electronic central unit is adapted to stop the fan when said operating parameter corresponds to abnormal fan operation;
    the plenum is adapted to retain water and the cover further includes a sprinkler device comprising a pump adapted to pump water into the plenum and at least one conduit connected to the pump and arranged to sprinkle the filtering layer when the pump is running;
    the construction further comprises at least one humidity sensor adapted to measure a humidity in the filtering layer, and an electronic central unit which is connected to the humidity sensor and to the fan and which is programmed to control the fan so that the fan does not operate when the measured humidity exceeds a first predetermined threshold;
    the electronic central unit is connected to the pump and is programmed to control the pump in order to water the filtering layer when the measured humidity is below a second predetermined threshold;
    the electronic central unit communicates with an external device adapted to give said electronic central unit information relating to an air pollution level, and said electronic central unit is adapted to operate the fan only when the level of air pollution air is above a predetermined threshold;
    the construction also comprises a support structure supporting the cover and delimiting under the cover a free space having a height of at least 2 m;
    the construction forms a shelter for public transport travelers.
    BRIEF DESCRIPTION OF THE DRAWINGS
    Other characteristics and advantages will appear during the following description of an embodiment, given by way of nonlimiting example, with reference to the accompanying drawings.
    In the drawings:
    Figure 1 is a schematic perspective view of a depolluting construction according to one embodiment, Figure 2 is a vertical sectional view of the construction of Figure 1, Figure 2A is a view of detail A of Figure 2 , and Figure 3 is a block diagram of the electrical devices of the construction of Figures 1 to
    2A.
    MORE DETAILED DESCRIPTION
    In the various figures, the same references designate identical or similar elements.
    Figures 1 and 2 show a depolluting construction 1, which depollutes the ambient air by suction through a filtering layer as will be described later.
    The depolluting construction 1 can in particular be a shelter for travelers V of public transport.
    The depolluting construction 1 comprises a cover 2 which comprises the aforementioned filtering layer. Coverage can be substantially horizontal (for example, horizontal or tilted by less than 10 degrees from a horizontal plane).
    The construction 1 may also optionally include a support structure 3 supporting the cover and delimiting under the cover a free space having a height of at least 2 m.
    In the example shown, the support structure 3 may include various support structures such as one or more display panels 4 and / or one or more posts 5, and vertical walls 6 such as glass walls
    or others can also to be supported through the supporting structure 3. As shown more in detail on the figures 2 and 2A, the cover 2 includes one or more devices of
    forced ventilation 7, which make it possible to draw ambient air through the aforementioned filter layer, which is permeable to water and air. This filtering layer can be a plant layer. The filtering layer may in particular comprise a substrate 8 on which vegetation 9 grows.
    The substrate 8 can be a geotextile or any other substrate on which the vegetation 9 can grow. The vegetation 9 can be a vegetation having particular depollution properties.
    Vegetation 9 can, for example, include bryophytes or consist entirely or almost entirely of bryophytes.
    Under the filtering layer 8-9, the cover 2 may include a plenum 10 which is delimited between:
    a rigid upper wall 11 which is permeable to water and air and which supports the filtering layer 8-9, a rigid lower wall 12 which is arranged under the upper wall 11 and which is impermeable to water.
    The upper wall 11 and the lower wall 12 can be kept apart from one another by a peripheral side wall 2a of the cover 2, with which they can form a closed box. Spacers can also be provided between the upper wall 11 and the lower wall 12.
    The upper wall 11 may include perforated portions 11a, to let air and water pass.
    The forced ventilation device (s) 7 are adapted to draw air into the plenum 10 through the filtering layer 8-9 and the upper wall 11, to discharge it into the waiting space for travelers V , under cover 2. The air thus sucked in is cleaned by passing through the filtering layer 8-9.
    Each forced ventilation device 7 can include:
    a watertight chimney 13 which extends into the plenum 10 between a lower end 13a tightly connected to the lower wall 12 and an upper end 13b opening into the plenum 10, the lower end 13a of the chimney 13 communicating with the atmosphere under the lower wall 12, for example through a grid 7a or the like;
    and a fan 14 disposed in said chimney.
    Each chimney 13 is further provided with a cap 15 disposed above said chimney 13, said cap 5 being impermeable and shaped to prevent water passing through the filtering layer 8-9 and the upper wall 11 falling into the chimney 13.
    The cap 15 may for example include a top 15a covering the chimney 13 and a peripheral rim 15b extending downward to a lower edge 15c from a periphery of the top 15a of the cap, leaving a free annular space 16 between the peripheral flange 15b and the chimney 13. The air sucked by the fan 14 into the plenum 10 therefore passes into this free annular space 16.
    The top 15a of each cap 15 may belong to the upper wall 11, this upper wall 11 then being perforated outside the zones forming the tops 15a of caps.
    When it rains or when the vegetation 9 is watered, the water which is not absorbed by the vegetation 9 crosses the upper wall 11 and falls into the plenum 10.
    Above the bottom wall 12 therefore a layer of water 17 is formed.
    This water 17 can be reused to water the vegetation 9, thanks to a watering device comprising: an electric pump 18 placed in the bottom of the plenum 10, and at least one conduit 19 connected to the pump 18 and arranged to water the layer filter 8-9 when the pump 18 is operating (it may for example from one or more porous pipes arranged in the substrate 8, in a manner known per se).
    It will be noted that the plenum 10 may comprise a water evacuation conduit 25 opening into the plenum 10 and forming an overflow making it possible to evacuate excess water 17, beyond a certain level of the layer. of water 17.
    The pump 18 can be controlled by an electronic central unit 20 (UC) such as a controller or the like (see FIG. 3).
    The electronic central unit 20 can also be connected to a humidity sensor 21 (Cl) arranged in the substrate 8 to measure a humidity in the filtering layer. The electronic central unit 20 can also be connected to a water level sensor 22 (C2) adapted to measure the water level 17 in the plenum 10.
    The electronic central unit 20 can also be connected to the fans 14 to control them.
    The electronic central unit 20 can be adapted (programmed) to control the fans 14 so that the fans 14 do not operate when the humidity measured by the humidity sensor 21 exceeds a first predetermined threshold (corresponding to a quantity of water in the filter layer 8-9 which in practice prohibits sucking air through this filter layer). This extends the life of the fans 14.
    As a variant or in addition, the fans 14 can also be adapted to measure and communicate to the electronic central unit 20 at least one operating parameter of said fan 14, for example the speed of rotation of each fan 14 or even the power electric consumed. In this case, the electronic central unit 20 can be adapted to stop the fans 14 when said operating parameter corresponds to an abnormal operation of the fans 14, which can correspond to an excess of water in the filtering layer 8-9. This also extends the life of the fans 14.
    The electronic central unit 20 can also be programmed to control the pump 18 in order to water the filtering layer 8-9 when the measured humidity is below a second predetermined threshold (below the first threshold) and when the level of water 17 is sufficient to allow operation of the pump 18.
    It will be noted that the electronic central unit 20 could also control a three-way valve or the like, making it possible to operate the pump 18 not to water the vegetation, but to evacuate water 17.
    The electronic central unit 20 can also optionally communicate with the outside, in particular with a server 26 (S) by a communication interface 23 (COM), in particular radio or wire. The server 26 can in particular give said electronic central unit 20 quantitative and / or qualitative information relating to an air pollution level.
    As a variant or in addition, the electronic central unit 20 can be connected to an external air pollution sensor 24 (POL), known per se, suitable for measuring one or more air pollution parameters.
    Depending on the information given by the server 24 and / or the air pollution sensor 26, the electronic central unit can thus control the fans 14 according to the air pollution information available to it, for example so as to operate them only in the event of a pollution peak in order to reduce their electrical consumption and extend their service life.
    Finally, it should be noted that the cover 2 could also include an upper grid or the like (not shown), covering the vegetation 9 and allowing people to walk above the vegetation 9 without damaging it.
