Definitions

  • the present invention relates to screening machines, particularly for screening waste containing fibrous materials, and to methods employing such screens. More specifically, the present invention relates to machines for screening waste containing sticky and moist fibrous materials, such as organic matter mixed with unwanted materials, including metals, minerals, plastics, and glass, and to methods for treating said waste using such screens.
  • Waste treatment processes for energy recovery and/or material recovery are constantly evolving.
  • methanization processes which aim to produce biogas, and composting processes applied after methanization or directly to fresh household waste containing organic matter.
  • the raw material for these processes can be waste from selective collection, green waste, kitchen waste, or even waste from the agri-food industry, or even household waste from non-selective collection containing different categories of materials, such as putrescible waste (food waste, green waste), paper, cardboard, glass, plastic, ferrous or non-ferrous metals, fabrics, sanitary textiles, and possibly dispersed hazardous household waste (batteries, etc.).
  • Solid Recovered Fuels from dry waste with high calorific value (wood, chlorine-free plastics, paper, cardboard, and wood), which are sorted, shredded, and refined to obtain a particle size fraction suitable for the intended use.
  • the raw materials for these processes can be residual household waste (RHW), ordinary industrial waste (OIW), and bulky waste from recycling centers of heterogeneous quality or too large to be processed in energy recovery units (incineration and co-incineration).
  • All these processes involve one or more sorting operations, and/or crushing and/or screening.
  • fine screening using a fine mesh allows, during the mechanical preparation phase preceding the actual biogas production, for the optimization of organic matter collection.
  • This organic matter which can be used for biogas production and composting, concentrates in the fine fraction, particularly after passing through a rotating pre-fermentation tube.
  • this fine screening should allow for the recovery of a waste fraction smaller than 5 millimeters, in which the organic matter suitable for biogas production and composting is concentrated.
  • Fine screening therefore makes it possible to select the materials to be treated according to their particle size and to separate degradable organic matter and mineral matter.
  • fine or even very fine screening is useful for calibrating RDF (Refuse Derived Fuels) and SRF (Solid Recovered Fuels), which are produced by shredding the light, coarse fraction from household waste and/or dry, high-calorific-value waste, including plastics, wood, composite wood, automotive shredder rejects, and textiles, from which the goal is to remove the fines.
  • Removing the fines is essential because they generally contain components with a low calorific value and/or higher moisture content, and because it prevents soot formation during fuel use.
  • the demand EP2 364 782 discloses the use of trampoline-effect screens for screening wet organic matter, with mesh sizes of 10 millimeters. It also mentions the risk of chemical attack on these screens when relatively wet organic waste is screened.
  • the mesh of these screens can consist of slits, square, rectangular, or round openings. Their dimensions typically vary between 8 and 12 for wet household waste. millimeters. With these devices, it seems difficult to screen waste containing moist organic matter with a mesh size smaller than 10 mm without clogging the screens. In all cases, the mesh opening expands and contracts with the movement of the screen, which can cause quality problems.
  • the demand WO2015 001514 discloses a screening machine according to the preamble of claim 1.
  • the present invention relates to a vibrating screening machine according to claim 1.
  • the present invention also relates to waste treatment installations comprising vibrating screening machines with screening grids, and to waste treatment processes implementing said machines.
  • the invention also relates to a brushing system automatic system deployed on the top face of the grid which ensures the cleaning of its upper and lower faces.
  • the screens of the screening machines according to the invention have, thanks to the specific configuration and the specific diameter of the metal wires which compose them, a flexibility which allows the brushes to pass through the screen to clean its underside, thus preventing the accumulation of material on this underside and avoiding clogging.
  • the specific configuration of the metal wires constituting the grid of the machines according to the invention therefore allows easy cleaning, in particular when the materials to be screened contain fibrous materials, in particular wet or sticky fibrous materials.
  • wire diameters are large enough to maintain a grid strength suitable for its use, and thin enough to allow an optimal passing area/overall grid area ratio.
  • the diameter of the wires of the screens of the screening machines according to the invention are between 1 and 1.7 millimeters, preferably between 1.1 and 1.6 millimeters, or between 1.2 and 1.6 millimeters, or between 1.3 and 1.6 millimeters, or between 1.4 and 1.5 millimeters.
  • screening means an operation of separating a particulate material into two particle size fractions by passing it through a grid or sieve comprising openings or meshes of a determined size.

  • longitudinal wires substantially in the same direction are understood to mean wires whose directions have a maximum angle between 0 and 5 degrees relative to each other.
  • the minimum non-zero distance between a wire and its neighbors means, in particular, the fact that the wires constituting the grids according to the invention are not joined together, for example not welded or woven together, even if, taking into account deformations, wires near the grid may have some non-permanent points of contact between them.

  • said cylindrical brushes (10) are mounted on a movable frame (8, 9).
  • the grids (2) are made of metal wires (5) having a substantially sinusoidal profile in the plane of said grid (2).
  • a substantially sinusoidal profile is defined as a profile that closely resembles a sinusoid, that is, composed of arcs similar to those of a sinusoid, with the same amplitude and period, regularly distributed on either side of a straight line that coincides with the direction of the longitudinal wires.
  • the sinusoidal nature of the profile is not affected by localized deformations that may exist on the wire.
  • the mesh L of the grid (2) is between 5 and 12 millimeters, preferably between 6 and 10 millimeters, preferably between 7 and 9 millimeters.
  • the mesh size L of the grid is defined as the maximum average distance between consecutive longitudinal wires of the grid, along a direction orthogonal to the direction of said longitudinal wires. For example, for a grid comprising wires with a sinusoidal profile, the mesh size L represents approximately twice the amplitude of the sinusoid.

  • waste containing organic matter may be unsorted waste, for example, unsorted household waste.
  • this waste may originate from sorted household waste or other sources and contain a significant fraction of organic matter associated with undesirable elements. These undesirable elements include, for example, packaging contaminated with organic matter.
  • wastes generally have a high moisture content, typically between 50 and 80%, and contain a large amount of sticky and/or fibrous material (kitchen waste, restaurant waste, unsold supermarket goods).
  • the waste having passed through at least one vibrating screening stage can be subjected to methanation treatment in a digester.
  • At least one vibrating screening step may be preceded by a pre-fermentation treatment in a rotating tube with a feed at one end and extraction at the other end.

  • Solid recovered fuels typically refer to fuels known as "SRF” or “RDF” (refuse derived fuel).
  • Fig. 1 This allows us to place the invention in its context. We can see in the upper left the input line where the waste to be treated is introduced. After a In the first primary screen, the fine fraction with a particle size of less than 450 mm passes through a rotating pre-fermentation tube and then through a trommel where the finest fraction, with a particle size of less than 80 mm, is recovered and passes through a second trommel where the finest fraction, with a particle size of less than 20 mm, is recovered to be passed through a screen, i.e. the sieve according to the invention, which allows to separate a first very fine fraction, with a particle size of less than 5 mm from a second fraction with a particle size between 5 and 20 mm.
  • a screen i.e. the sieve according to the invention
  • the first fraction passes through a mechanically agitated horizontal digester with at least partial recirculation via a mixing hopper.
  • the second fraction first passes through a ballistic separator to remove heavy waste before entering a digester in a similar manner to the first fraction.
  • the digestate undergoes a maturation phase through draining or dehydration to stabilize it, transform it into fuel, or make it suitable for agricultural use.
  • Fig. 2 we can see the screening device used in the process according to the invention.
  • the screening device comprises a frame 1 supporting an inclined grid 2.
  • the grid 2 is situated in a plane inclined at an angle ⁇ to the horizontal.
  • grid 2 is mounted on a static grid support with an adjustable tilt from 30 to 60 degrees.
  • the tilt is 42° relative to the horizontal.
  • This steep incline allows the product being treated to flow down the slope without being forced through a mesh. Clogging is therefore much less frequent.
  • Grid 2 has an elongated shape, with a lower end (E2) and an upper end (E1) attached to tensioning systems 3 that apply a permanent voltage to grid 2 to maintain it essentially flat.
  • Electromagnetic hammers 4 which transmit vibrations to the grid, are mounted on the sides of the grid, attached to the frame 1.
  • These electromagnetic hammers can, for example, consist of electromagnets driving rotating cylinders fitted with protruding lugs or pins, arranged just below the grid, and extending transversely to the frame 1, at the level of the crossbars 6. The impact of the pins on the bar(s) 6 allows vibrations to be transmitted to the grid.
  • Grid 2 ( Fig. 4 ) is presented in the form of a series of longitudinal wires 5 exhibiting a substantially sinusoidal profile arranged in a rectangular shape.
  • the wires 5 are all on the same plane, with the distance between a wire 5 and its neighboring wires varying between a maximum and a minimum. However, even when the distance between a wire and its adjacent wire is minimal, there is no weld between the two wires. This particular arrangement was chosen after numerous tests. It minimizes clogging and facilitates cleaning of the grid. The maximum distance between the wires determines the mesh size L.
  • Crossbars 6 for stiffening are provided at regular intervals to maintain a constant spacing between the wires 5.
  • the four electromagnetic hammers are positioned opposite the stiffening bars.
  • the frequencies used are generally between 10 and 60 Hz. When using multiple screening stages, it is possible to use different frequencies for each stage.

  • a trolley 8 is suspended beneath the frame 7 by means of rails, allowing it to slide transversely relative to the grid 2.
  • the trolley 8 consists of metal profiles assembled together to define, in particular, an upper surface 8a, on which rollers are fixed that cooperate with the rails provided on the frame 7, and an inclined lower surface 8b, parallel to the surface of the grid 2, beneath which is mounted a retractable support 9 supporting cylindrical cleaning brushes 10.
  • Means not shown are provided for driving the cylindrical brushes in rotation around their axis.
  • the retractable support 9 has two parallel faces 9a and 9b connected by connecting rods 9c.
  • the first face 9a is mounted to slide under the carriage 8 while the second face 9b supports the cylindrical cleaning brushes 10.
  • Two grids (1.75 meters by 3.60 meters) are planned, placed side by side and fed by a V-shaped chute (not shown). This chute allows both grids to be fed simultaneously or just one of them.
  • the trolley 8 can therefore be located above either of the grids or offset to the side, in a waiting position.
  • the trolley 8 is positioned in the waiting position as shown on Fig. 13 .
  • the trolley 8 When a cleaning operation is deemed necessary, the trolley 8 is moved over one of the grids 2 which will be cleaned ( Figs. 11 and 12 ). The retractable support 9 is then in the folded position as illustrated Fig. 6 .
  • the retractable support 9 is unfolded ( Fig. 7 ) to bring the cylindrical brushes 10 into contact with the grid 2.
  • the retractable support 9 then moves downwards relative to the trolley 8, parallel to the grid 2, to carry out the cleaning ( Fig. 8 And 9 ).
  • the retractable support 9 is folded away ( Fig. 10 ) before the return of the carriage 8 to the waiting position ( Fig. 13 ).
  • each screening machine which has its own feed hopper and its own cleaning system comprising a carriage, one or more cylindrical brushes, and a system for moving the carriage over the screen.
  • the feed of material to the screen from the hopper is stopped, the carriage moves across the screen, and the cylindrical brush(s) in contact with the screen clean it.
  • the carriage and the brushes are located at the bottom of the screen, in a raised position above the end (E2).
  • the grids that were used are as shown figure 2 These are flat grids with longitudinal wires of sinusoidal profile, not joined.
  • the effective screening area was 3.45 m2 in all tests; the duration of the tests was 12 hours, including a 1.2 minute cleaning (feed stoppage) every 10 minutes.
  • the mass capture rate of the 0-5 mm fraction (of size less than millimeters), in the material passing the screen, is obtained by sieving this fraction in a sample of mass m of the feed material and weighing the mass obtained m' and carrying out the same operation for a mass m of material passing, to obtain a mass m";(m"/m')*100 is the capture rate (%).
  • Tests 1 and 2 show a low material throughput, indicating a screen clogging problem due to excessive wire rigidity and a small screen area. This is confirmed by the low capture rate of the 0-5 mm fraction.
