  • the system comprises discharge means comprising at least one discharge electrode brought to high voltage and producing in its vicinity an ionization of the air to be depolluted.
  • upstream and downstream are to be understood taking into account the direction of the air and water flows present in the system.
  • the air pollution control system of the invention is based on the principle of wet electrofiltration, also called the principle of wet electrostatic precipitation.

  • system 1_x can be composed of several modules Mi assembled together and placed end-to-end.
  • the system can thus comprise n modules of the same type, n being greater than or equal to 1. It will be considered that a single module Mi is however sufficient to produce the system and implement the principle of the invention.
  • a module Mi of the system is in the form of a preferably one-piece element.
  • a module Mi comprises a duct 30 with a closed cross-section located in a meridian plane defined with respect to said central axis in which it is a question of passing both an air flow Fi_air and a water flow F_eau.
  • THE conduit 30 is made of a material which is electrically insulating.
  • the air flow Fi_air and the water flow F_eau are advantageously oriented in the same direction and in the same direction inside the duct 30 ( picture 3 ).
  • the duct 30 thus comprises a wall 300 delimiting an internal space forming the flow section 301 of the duct 30 and an external space located outside.
  • This flow section 301 comprises a flow channel 302 for the air flow F_air and a flow ramp 303 for the water flow F_eau which are superimposed, the two flows being intended to be in contact with one another. the other during their circulation in the duct 30.
  • the duct has an upper border located at the entrance to the duct and a lower border located at the end of the duct.
  • the module Mi comprises an air inlet at its upper border through which the air flow Fi_air is injected and a water inlet at its upper border through which the water flow is injected.
  • the module then comprises at least two electrodes 33, 34 between which is established the electrostatic field E which allows the precipitation of the particles P of the air to be depolluted in the flow of water F_water.
  • a first electrode 33 is advantageously integrated or fixed to the wall 300 of the conduit 30 which forms the flow ramp 303 of water so as to be covered by the flow of water F_eau when the latter circulates on the ramp.
  • the first electrode 33 can be made continuously over the entire length of the conduit 30 or only over part of the length of the latter (as can be seen in the picture 3 ).
  • the module Mi can also include several electrodes 33 of this type, spaced apart by a given distance. The flow of water F_eau in contact with the first electrode 33 thus plays the role of an electrode kept grounded.
  • the second electrode 34 plays the role of active electrode. This one is also advantageously integrated or fixed to the wall 300 of the conduit 30 ( figures 2, 3 and 4 ). It is permanently emerged, ie outside the flow of water F_water. It is advantageously carried out continuously over the entire length of the conduit 30 ( figure 2 ).
  • each electrode 33, 34 may be in the form of a metal plate, for example rectangular, integrated into the wall of the duct.
  • the first electrode is thus in contact with the flow of water F_water and the second electrode is in contact with the flow of air Fi_air.
  • the surface of the first electrode 33 which is in contact with the flow of water F_eau is advantageously flush with the flow surface of the conduit 30.
  • the first electrode 33 advantageously extends over all or part of the width of the flow surface of the flow of water F_eau.
  • the second electrode 34 can advantageously have a width at least equal to that of the first electrode.
  • the electrostatic field E created between the two electrodes follows a direction transverse to the directions of the water flow and of the air flow, advantageously perpendicular to these directions.
  • each electrode 33, 34 can be made as a separate metal cable.
  • the cable can be fixed on the flow ramp of the water flow.
  • the cable is fixed to the upper internal face of the conduit.
  • the flow of water F_eau is represented curved on its surface, to take into account the centrifugal force due to the helicoid shape of the flow ramp of the conduit, the said effect tending to displace the flow of water at the exterior of the ramp.
  • the flow of water F_eau flows by gravity in the pipe 30, said pipe being able to be produced according to a helix inscribed in various types of cylinder.
  • the cylinder can be of any section, for example circular, elliptical or of any other shape. In the appended figures and advantageously, the section of the cylinder is circular.
  • the flow ramp 303 of the water flow F_eau has a flow surface that is inclined with respect to the vertical. Its inclination is for example defined by an angle A ( figure 2 ) relative to the horizontal plane which is greater than 0° and less than 60°, advantageously between 5° and 45°. This angle can be constant over the entire length of the duct or variable.
  • the slope must be steep enough to allow the flow of water F_eau to flow but not too steep to remain stable and maximize its travel time, so as to increase the duration of the encounter between the air to be depolluted and the flow of water F_water.
  • the flow surface on which the flow of water F_eau is caused to circulate is advantageously continuous, hydrophilic, smooth and flat, so as to allow the flow of water F_eau to be as stable as possible during its flow and to keep an electrostatic field E as constant as possible over the entire length of the conduit 30. It will also advantageously be made of a corrosion-resistant material.
  • the duct 30 of the Mi module is made along a helix advantageously inscribed on a right circular cylinder.
  • the radius and the pitch of the helix are chosen to obtain the desired inclination of the flow ramp.
  • the flow ramp of the water flow F_eau thus follows the helical profile defined by the walls of the duct.
  • the duct has a first end through which an incoming water flow F_eau_in is injected and may include a first opening 40_i made through its wall, through which an incoming air flow Fi_air_in to be treated by this module is injected and a second opening 41_i made through its wall through which emerges an air flow Fi_air_out treated by this module.
  • the first opening 40_i is of course made upstream relative to the second opening 41_i.
  • the flow of water F_eau is caused to descend along the helical ramp and the electrodes 33, 34 described above and integrated into the module allow the creation of the electrostatic field E to trap the particles present in the flow of air.
  • each module Mi may comprise an additional duct 60, for example central and coaxial with its helical duct 30.
  • This duct 60 thus serves as a collector of purified air and can be connected to the air outlet of the module Mi to receive the outgoing air flow Fi_air_out cleaned by the module Mi.
  • the air purified by each module Mi can thus be transferred directly to the center of the system in the intake manifold formed by this duct 60.
  • the cleaned air can then be returned directly to the base of the system.
  • this duct 60 could be arranged differently.
  • the conduit 60 for recovering the module Mi of row i is connected to that of the module of row i-1 and to that of row i+1, so as to form a single tube along the column.
  • the wall of this duct 60 can itself form the internal section of the duct 30 of the helical-shaped module. It is thus possible to have an entirely one-piece solution.
  • the system 1_x can comprise a single module of this type or even several modules connected in series so as to assemble the ducts together in a contiguous manner and thus form a single duct and a more or less high column of modules.
  • the assembled modules Mi are advantageously all identical.
  • the cross section of the common helical duct formed by the stack of modules is advantageously constant over the entire height of the column.
  • the system can thus comprise n modules, with n which is then greater than or equal to 2.
  • Each module Mi of the system can be identified by a rank i, with i ranging from 1 to n.
  • the rank 1 module is the module through which the flow of water F_eau_in is injected.
  • the rank n module is the last module in the system. This comprises a water outlet through which the flow of water F_eau_out loaded with trapped particles is evacuated.
  • the water outlet can be connected to the sewers and/or to a purification installation 4 to treat the outgoing water flow.
  • Other solutions could of course be considered.
  • each module Mi of the system comprises an air inlet to allow the system to take air to be depolluted at several intake points over the entire height of the column (incoming air flows F1_air_in, F2_air_in, Fn_air_in).
  • Each module of the system can include an air outlet to evacuate the air that it has just treated and decontaminated (outgoing air flows F1_air_out, F2_air_out, Fn_air_out).
  • the flow ramp 303 of the water flow of each module of row i is connected to the flow ramp of the module of row i-1 and to that of the module of row i+1 to maintain the same water flow F_water for the whole system.
  • FIG 9 illustrates the assembly of two modules M1 and M2 each having a helical shape and makes it possible to visualize the different flows present.
  • the module M1 receives through its opening 40_1 a flow of air F1_air_in and the flow of water F_eau via the inlet F_eau_in.
  • This module M1 evacuates through its opening 41_1 the flow of air F1_air_out which is treated and depolluted.
  • the flow of water F_eau continues its path in the second module M2.
  • a second airflow F2_air_in is injected into the module M2 through the opening 40_2 and the airflow F2_air_out processed by this module M2 exits through the opening 41_2. If another module is connected downstream, the water flow F_eau continues on its way, otherwise it is sent to a treatment system 4.
  • the module of rank i may include a crown 50 to collect the flow of water. It also comprises the air outlet for the flow of air leaving Fi_air_out of this module Mi, located upstream of this crown 50.
  • the ramp of the module of row i+1 is connected to said crown to recover the flow of water F_system water.
  • the air inlet (air flow Fi+1_air_in) of the module of row i+1 is positioned downstream of said crown 50.
  • each module Mi of row i comprises first so-called upstream mechanical connection means at its upper border and to be assembled to the module of row i+1, the module of row i comprises second so-called downstream mechanical connection means at its lower boundary.
  • electrical connection means can thus be provided on each module of row i to ensure the electrical continuity of each of its electrodes with the corresponding electrode of the module of row i-1 and with the corresponding electrode of the module of row i+1.
  • these electrical connection means will be referred to as upstream and downstream to connect respectively to the upstream module and to the downstream module.
  • the system for generating the water flow F_eau_in at the water inlet of the row 1 module of the system can be designed based on one of the following two solutions, each comprising several variants.
  • a pump is arranged to suck up the flow of water F_water and inject it into the system.
  • the aspirated water can be taken from a drinking water circuit or from a "grey" water circuit after having been filtered to operate in an open circuit.
  • the air pollution control system of the invention may comprise a water circuit operating in a closed circuit.
  • the water flow F_eau is thus generated by this internal water circuit operating in a closed circuit, in which the water, laden with particles and gases, is taken from the base of the system and treated before reinjection at the top thanks to the pump .
  • the flow of water F_eau can come directly from rainwater coming from a tank placed above the system to let the water flow into the conduit by gravity.
  • This tank can in particular be a flexible storage tank, made from a polymer-coated textile and generally used against the risk of fire or to store drinking water. It can also be connected, like a downspout, to an overflow placed on a roof or on a terrace or any other pre-existing structure for collecting rainwater.
  • hybrid solutions can be considered depending on the rainfall intensity of the place where the pollution control system is located, a variant from the first solution described only intervening to fill a deficit of water stored in a variant of the second solution operating from rainwater.
  • water flow regulation points can also be provided between each module of the system.
  • each air flow can be carried out by suction.
  • a pump or a fan 6 can be connected to the base of the system to generate each air flow Fi_air_in by suction in the whole system.
  • This pump or this fan 6 can be connected to the air outlet of the intake duct 60 of the row n module located at the base of the system, the latter being in fact connected to the air outlets of each module and therefore at their respective air inlets.
  • the section of the intake duct 60 can increase from the highest module to the lowest module, over the entire length of the system to compensate for the pressure drops along the column and thus make it possible to maintain an air flow at identical treatment at the level of each module.
  • the voltage generator G is intended to apply a voltage between each first electrode 33 and each second electrode 34 of each module Mi to establish the electrostatic field E necessary to precipitate the particles in the film of water.
  • the voltage generator G is connected to the second electrode 34 of a single module of the system, the electrical continuity of the second electrode being ensured along the system. This could also be the case if the first electrode of each module is continuous over the entire length of the module.
  • the system may comprise a device 5 intended to charge the particles present in the air to be depolluted upstream, so as to better ensure their precipitation by electrostatic effect.
  • This device may comprise at least one discharge electrode consisting of a high voltage wire or tip and producing in its vicinity an ionization of the air to be depolluted.
  • This type of device 5 is well known in the state of the art. This device is for example arranged upstream of each air inlet of the system in order to load the particles of the air to be depolluted.
  • each module of the system of the invention can be made in such a way as to have at least two conduits 30.1, 30.2, thus forming two flow ramps in a helix, wound around the same axis.
  • the two ramps can be identical and offset in height relative to each other, as shown schematically in the figure 11 .
  • Other configurations could be envisaged.
  • the other characteristics of the invention can be applied to this specific architecture. Some means may be pooled for the two ramps of the system, in particular the duct 60, the air flow generation system, the water flow generation system, the voltage generator, etc. In the same size, it it will thus be possible to increase the processing capacity of the system.
  • the system can also integrate a command and processing unit UC as well as a communication system allowing it to communicate via a wired or wireless link with a central unit UCC.
  • the system is therefore thus communicating and its use can be controlled in a manner adapted to the level of pollution present or according to other parameters measured.
  • the central unit UCC can thus be required to manage a complete depollution installation comprising several dispersed systems (1_1, 1_2, 1_3 on the figure 12 ) in different locations.
  • Each system must in particular be able to be controlled to act quickly and intensely following a pollution incident.
  • a judicious network of systems will make it possible to intervene as close as possible to the incident by controlling one or more of the systems in an appropriate manner.
  • V_air, V_water air flow and water flow control valves may be provided in the system to control the air flow and water flow at each air inlet of the system and the system water inlet. These valves can be controlled directly by the system's control and processing unit UC.
  • Each system should operate at a rate that is appropriate to the pollution level of its surrounding air.
  • the flow of air to be depolluted which is sucked in can therefore advantageously be regulated by the control and processing unit UC of the system.
  • the 1_x system can integrate up to 70 sensors on the modules, providing the level of particulate and gas pollution as well as pressure, temperature and humidity conditions. These measurement data can be sent to the control and processing unit UC to implement the regulation. The control and processing unit can then regulate the power supply which conditions the voltage of the electrodes of each module, that of the various fluidic adjustment devices as well as the means of generating the air flow (pump and/or fan) to adjust the airflow in the system.
