Definitions

  • the field of the invention is that of waste treatment. More specifically, the invention relates to the treatment of common waste of the type of those encountered in particular, but not exclusively, in garbage household or industrial waste.
  • the quality of the waste can initially be controlled by a radioactivity detector, then, in a second step, globally and coarse thanks to a visual control by an operator.
  • Such a practice usually poses congestion problems storage, when waste arrivals are overabundant compared to the processing capacity of the corresponding facilities.
  • a limit of waste treatment centers concerns waste preparation carried out in order to optimize the yields of the downstream treatment processes (by incineration, biologically, by storage %) implemented.
  • this preparation of waste may be adapted only to certain wastes, other wastes which could lead to a loss of yield during this preparation phase, or even harm it.
  • the purpose of the invention is in particular to overcome the disadvantages of the prior art.
  • the purpose of the invention is to provide an installation of waste treatment, in which the control, sorting and disposal of certain pre-determined wastes are more reliably performed compared to the art prior.
  • Another object of the invention is to provide such an installation of waste treatment whose performance in terms of quality are better than those of existing facilities.
  • Yet another object of the invention is to provide such an installation whose performance in terms of recycling and / or recovery of materials are improved compared to existing installations.
  • Yet another object of the invention is to provide such an installation which is more efficient in terms of toxic waste management than the installations of the prior art.
  • Another object of the invention is to provide such an installation which is simple in design and easy to implement.
  • the sorting operations are facilitated or at the very least optimized because the first conveying means, on which are unloaded the waste, allow a thin layer spread of the waste.
  • Another advantage of the invention lies in the fact that the control, the detection and disposal of the predetermined waste are carried out directly to the passage of waste on the means of conveying.
  • said sorting unit is provided with seconds conveying means and has a first zone where said elements or unwanted substances can be detected by visual recognition and separated by said evacuation means, a second zone where said means detecting means are used to detect said elements or substances unwanted ones having escaped said visual recognition and a third zone where said evacuation means can be used to evacuate said undesirable elements or substances.
  • the third zone allows the evacuation of toxic waste difficult to detect visually (the detection of certain types of waste toxic can however be achieved visually).
  • This zone can also allow the evacuation of harmful waste for the operation of an area pre-treatment located upstream of a downstream waste treatment zone.
  • Toxic waste means any waste which, by reason of its composition, would reduce the yields of downstream processing units by inhibiting the processes used, or would generate residues and / or effluents from downstream treatment loaded with these toxic products.
  • the term "harmful waste for the operation of of a pre-treatment area” any waste likely to reduce the performance of the pre-treatment in question, or presenting an incompatibility with said pre-treatment (for example, if the pre-treatment comprises a phase grinding process, the non-crushable waste will be removed from the waste stream intended for pre-treatment).
  • said means for conveying said sorting unit are provided with damping means.
  • the first and second conveying means are in line.
  • the detection means may vary and / or be chosen according to the needs of the installation, and in particular according to the downstream processing and preprocessing. Of course, other types probes are possible without departing from the scope of the invention.
  • said first zone comprises at least one camera.
  • Such a characteristic contributes to the automation of the installation, and therefore limits the risks of imperfect sorting such as that which could be executed by an operator.
  • the seeding means can be implemented in particularly when it is planned to mix the waste with sludge. he can also be provided, according to another conceivable embodiment, to add additives to the waste, these additives being chosen to accelerate the methanogenesis in the context of anaerobic downstream treatment.
  • said pre-treatment zone comprises means for adjusting the temperature and / or humidity and / or particle size and / or chemical composition of said non-hazardous waste evacuated.
  • said adjustment means comprise a zone of heating a heating fluid from a final treatment area said waste.
  • Energy savings can be considered in this way, in particular in the case where the downstream treatment of waste includes a storage phase anaerobic.
  • said first zone is intended to dispose of waste including metals and / or wood and / or waste electronics and / or household waste and / or rubble and / or toxic waste.
  • waste can indeed represent large volumes of waste that can be recovered and / or recycled in terms of energy, in other sectors and / or other industrial sectors.
  • an installation according to the invention comprises first conveying means 1 of the waste of a zone of unloading 2 to a sorting unit 3.
  • the conveying means 1 allow dynamic storage temporary waste and include two sections 11 consisting of carpets with scales.
  • the waste is unloaded on the first section 11, the two sections 11 being surmounted by a cowling 12 inside which circulate the waste, this rollover being placed in a depression so as to avoid dust emissions outside the cowling.
  • each of the sections 11 has a length of about 15 m, and drives waste at a speed of about 1 m / min (more speeds nits can be selected and conveyors can have different).
  • the sorting unit comprises detection means undesirable elements or substances in the waste, as well as means of evacuation of these elements or undesirable substances.
  • the sorting unit comprises second conveyor means 31 (provided with damping means not shown) and has a first sorting area 32 in which undesirable elements or substances can be detected by visual recognition (preferentially with the aid of a non shown), then evacuated from the conveyor belt 31 with a grapple 33.
  • the sorting unit has a retractable sorting conveyor 36, to discharge the waste transported by the conveying means 1 directly in a truck or container (for example in case of stopping Installation).
  • the conveyor means 31 of the sorting unit scroll to a speed of about 3 m / min, for a speed of scrolling of the first conveying means of the order of 1 m / min.
  • first and second conveying means makes it possible to envisage, in the unit of sorting, a scroll of waste layer of a thickness of about 30 cm.
  • the sorting unit 1 further comprises a second zone 34 in which detection means are used to detect the elements or substances undesirable substances that have escaped visual detection in the first zone 32.
  • the elements or substances detected in the second zone 34 are evacuated with the grapple 33 in a third zone 35 of the sorting unit.
  • sorting and evacuation are carried out from the means of conveying recyclable waste, and in particular waste metal or wood, electronic waste, household electrical waste or still rubble, as well as possibly some of the toxic waste.
  • the second zone 34 is provided to detect toxic waste in particular by means of detection such as imaging probes, radiation probes, probes thermal or radio frequency probes.
  • the installation comprises a pre-treatment zone 4, upstream of a downstream treatment of the waste.
  • the pre-treatment consists of a grinding performed using a grinder 4 (other types of pre-treatment may be made according to other conceivable embodiments, in particular to using drying means and / or seeding means), this upstream downstream processing (in an area not shown).
  • a preprocessing zone includes an installation according to the invention
  • the second and third zones are then provided for sorting and also remove unwanted or harmful waste for operation of the pre-treatment area in question.
  • the pre-treatment zone includes means for adjusting one or more of the operating parameters of the downstream process stream, for example the temperature, humidity, granulometry or the chemical composition of waste.
  • Such a zone may for example be a heating zone using the energy of an incinerator or effluents from downstream treatment, such as example the biogas formed during anaerobic treatment.
  • the first means of conveying and the second conveying means are in continuity one on the other, and preferentially placed in line as it appears in the figure 2.
  • the installation comprises two parallel lines comprising each of the first conveying means and a sorting unit according to the principle of the invention.
  • the first conveying means by their in inclined position, avoid the need to raise the platform unloading or to make a pit intended to integrate in particular the sorting.
  • FIGS. 3 and 4 show an installation according to the invention, in which two lines integrating each of the first conveying means 1 and a sorting unit 3 are provided in alignment with one another.
  • the sorting unit is installed in a pit, the unloading platform 2 being possibly raised with respect to the ground level.
  • an installation according to the invention is modular, in meaning that it can present one or more sorting unit and first means of conveying, where the sorting units are placed or not in a pit, and the unloading platform being elevated or not.
