Definitions

  • the present invention relates to a device for purifying a gaseous medium loaded with particles of all kinds, such as dust particles, organic particles in suspension in the exhaust gases of all kinds and in particular from diesel engines. ..
  • It is more particularly intended for use in an industrial installation, an establishment (hospital, restaurant, etc.) or even a building for residential use (house, apartment), in particular in the form of a mobile device.
  • This treatment device comprises a corona-effect electrofilter comprising a longitudinal casing of cylindrical shape in which extends a longitudinal passage for the gases to be treated, an emissive structure extending longitudinally in the center of the passage and a collecting structure extending longitudinally between the passage and the envelope and comprising a plurality of cavities forming housings for trapping the particles contained in the gaseous medium, the emissive structure comprising a plurality of serrated plates arranged transversely to the longitudinal direction and forming points directed towards the collecting structure . These serrated plates are all carried by a rod connected to a circuit providing a stabilized high voltage.
  • Another device for purifying a gaseous medium loaded with particles is described in JP S58 119355 A .
  • the present invention aims to provide a device of this type, better suited to the uses mentioned above, while remaining effective, and also leading to other advantages.
  • the present invention proposes a purification device optimized in terms of efficiency as well as the aforementioned uses.
  • each of the emissive structures or electrodes as desired, in particular to obtain for example effects of ozone production or not, to play with the flow of the gaseous medium in the filtration chamber , or even bringing each of the electrodes individually to a different voltage.
  • these arrangements also make it possible to produce a device that is easy to manufacture and also to maintain which, moreover, can be produced, as needed, in the form of a compact structure.
  • the device 10 for purifying a gaseous medium laden with particles forming the subject of the embodiment of the figures 1 to 3 is a free-standing device, which can be mounted on wheels. It has an overall rectangular parallelepiped configuration.
  • This purification device 10 generally comprises an electrostatic filtration chamber 11 and suction means 12 downstream of this electrostatic filtration chamber, to extract from the chamber the gaseous medium stripped of its particles.
  • this electrostatic filtration chamber 11 is, here, interposed between an inlet compartment 13 through which the gaseous medium laden with particles enters the device and more particularly into the electrostatic filtration chamber 11 and an outlet compartment 14, thanks to which the suction means 12 are housed and by which the gaseous medium stripped of its particles is discharged into the surrounding environment.
  • the inlet compartment 13 comprises a frame 15 carried by a bottom 16 and formed of four walls assembled at right angles, one of which, 17, is perforated to allow the gaseous medium to enter the device, here from below the electrostatic filtration chamber 11.
  • the gaseous medium laden with particles thus enters the purification device 10, in a direction substantially perpendicular to that of flow in the filtration chamber 11.
  • a pre-filter 18 intended to retain large particles. This is, for example, a metal knit or stretched metal filter.
  • the outlet compartment 14 for the gaseous medium stripped of its particles comprises a box 19 in the shape of a rectangular parallelepiped, the upper wall 20 of which is perforated to allow this gaseous medium stripped of its particles to pass. .
  • suction means 12 which are here in the form of a fan, are mounted in this box 19, at the level of the face of the latter opposite the perforated wall 20.
  • the gaseous medium thus flows horizontally in the inlet box 15 then vertically to the outlet of the purification device 10.
  • the suction means 12 are arranged directly at the outlet of the electrostatic filtration chamber 11 and are in fluid communication therewith to suck in the gaseous medium.
  • This electrostatic filtration chamber 11 comprises, here, two supports 21 of emissive structures arranged in the passage formed by the electrostatic filtration chamber 11 between an inlet therein (after the prefilter 18) and an outlet thereof (just before the suction means 12).
  • collecting structures 22 designed to trap the particles contained in the gaseous medium charged with particles.
  • Each support 21 of emissive structures comprises, more precisely, a plurality of emissive structures 23 arranged in the passage, one after the other, between the inlet and the outlet of the electrostatic filtration chamber 11.
  • Each emissive structure 23 is in the form of a plate, preferably a blade, here five in number per support 21, designed to force the gaseous medium laden with particles to flow in the vicinity of the collecting structures 22.
  • Each blade 23 also comprises, at its periphery, points 26 directed towards the collecting structures 22.
  • Each support 21 comprises two U-sections 27 assembled, parallel to each other and back to back, by four spacers 28 each welded to a corner of the U-section 27. It should be noted in this respect that the fourth spacer 28 is not visible in the figures.
  • Each blade 23 comprises, for its mounting on this support 21, a rod 29 welded to each of two opposite mounting edges 30 which extend generally perpendicular to the edges of the blades 23 provided with the points 26.
  • the U-sections 27 are provided, for receiving the rods 29, with passage openings 31 for these rods.
  • the maintenance in position on the support 21 of each of the blades is obtained, in the case of the present embodiment, by means of the interposition of a nested insulator 32, by complementarity of shapes (of square section), in an opening 31 and receiving, itself, a rod 29 of the blade 23.
  • Each rod 29 is, to do this, threaded and engaged in a central cylindrical hole of the insulator 32 and fixed by a nut (not visible in the figures and housed in a passage hole 36 of square section preceding this cylindrical hole in the insulator and ending before this last hole with a bearing surface for the nut), so that each blade is mounted with possibility of angular orientation in the electrostatic filtration chamber 11.
  • the insulator can also be protected by means of a bell and a counter-bell or deflectors, in the manner of what is described in the application for patent cited above ( WO 01/19525 ). This makes it possible in particular to avoid electrical bridges.
  • Each blade 23 forming an emissive structure is, here, brought to a cathodic voltage of the order of 10 kV by a circuit supplying a high voltage 33, housed in a control box 34 mounted, within the framework of this embodiment, in box 19.
  • each collector structure 22 comprises, in the context of the present embodiment, a metal knit in the form of a plate brought, here, to an anode voltage of the order of 5 kV, being connected to a circuit 35 providing a high voltage, which is also housed in the control box 34.
  • the collector plates 22 can be mounted in a frame by means of rods passing through openings made in this frame and the interposition of insulators, in a manner similar to that provided for the blades 23 on their support 21. Therefore, this has not been shown in the figures, for the sake of simplification.
  • connection to the circuit 35 can be obtained, for example, with a leaf spring integral with the upper box 19 and in contact with a rod of the plate 22.
  • the implementation of one or more of these blades can also allow to maintain the plate in position within the device and its placement and removal therefrom.
  • the purification device in accordance with the present invention thus proves to be particularly flexible, in particular thanks to the mounting of the blades 23 on the supports 21, one independently of the other (and electrically isolated from each other on their support).
  • This makes it possible in particular to orient each of the blades as desired, in particular to produce ozone having a germicidal effect on microorganisms of the virus and bacteria type.
  • This production of ozone can be obtained by orienting the blades 23 perpendicular to the collector plates 22, while an orientation different from the perpendicular (the tips of the collector structures 22 are moved away) will stop or reduce this production of ozone.
  • the blades 23 are always oriented so as to form a non-zero angle with the plane of the collector plates 22 which extend parallel to one another, the blades 23 being themselves aligned according to a parallel alignment to these same planes.
  • edges of the blades 23 provided with the points 26, extend to the vicinity of the collector plates 22, leaving only a space remaining avoiding the formation of arcs in a position in which the blades 23 are extend perpendicularly to these collector plates 22 or, in practice, a space of the order of one millimeter for 1000V of voltage applied to the blade 23 corresponding.
  • negative ions produced by the ionization taking place in the electrostatic filtration chamber are also of interest in terms of the therapeutic effects that they can generate.
  • a door 37 is, moreover, provided to isolate the side collector plates 22 from the surrounding environment, while being able to access them to remove them from the purification device 10 with a view to cleaning them.
  • This device also proves to be easy to manufacture, for example from cutting and, where appropriate, bending of stainless steel plates.
  • the device can operate vertically, as seen on the figures 1 to 3 , or horizontally.
  • emissive structures 23′ here plates, extending side by side, preferably parallel to one another, in the passage, with an arrangement in staggered from one row to the other.
  • a single support 21′ is moreover provided in the context of this embodiment to carry these emissive structures 23′.
  • the spikes 26" do not protrude from the periphery of each of the plates, but are formed inside the corresponding plate, by means of a longitudinal cut made therein in the vicinity of each of its longitudinal edges.
  • a cutout forming two rows of rounded notches 25", facing each other and forming between them the points 26" directed towards the collecting structures.
  • Each cutout is further formed so that the 26" tips of the two rows are staggered.
  • the device according to the invention could comprise a UV radiation lamp arranged upstream of the entrance to the electrostatic filtration chamber 11 (for example in the box 15) to attract and kill insects, such as mosquitoes .
  • a finishing filter for example based on activated carbon, in metal knit or stretched metal, can also be implemented between the electrostatic filtration chamber 11 and the suction means 12.
  • Each collector structure can also comprise one or a succession of stretched metal plates instead of the metal knit or even be made from an alternation of metal knit and stretched metal plates.
  • voltages can also be considered for the emitting and collecting structures.
  • it can be envisaged to bring, in a succession of stretched metal plates forming a collector structure, one plate out of two to a voltage of the order of 5 kV and to ground the following one.
  • the voltages are chosen to be between 10 and 50 kV.
  • the circuit supplying a high voltage will of course supply a positive or negative high voltage.
  • Another possibility could be to bring one out of two emissive structures to a positive high voltage and the other to a negative high voltage, while the collecting structures would be grounded or a positive high voltage.
  • a frame made from sections, such as angle irons, can complete the device, for example for its mounting on wheels or the positioning of the central collecting plates on rails in the form of U to facilitate their sliding.
  • each blade may, to increase the turbulence at the level of the aspirated flow, be twisted.
