Definitions

  • the invention relates to the melting and incineration in a furnace of more or less toxic, metallic, organic and inorganic materials and waste such as oxides, glasses, phosphates and metals.
  • the metal container containing the waste can be used as a shuttle for introducing the waste into the oven. In this case, it can be cut gradually in the oven, to limit the rate of combustion, but can not be recycled and represents a significant part of the final waste.
  • the cutting system for example using a plasma torch, placed in the oven is also complex and expensive.
  • An alternative is to place the waste package in a carton that serves as a shuttle. This solution limits the risks in the airlock, but does not solve the problem of the burning speed of the waste package, as soon as the cardboard has burned.
  • the object of the invention is therefore to avoid the aforementioned drawbacks relating to the solutions presented above by presenting another method and another device for introducing waste into the furnace.
  • a first main object of the invention is a basket for supporting waste to be introduced and incinerated in an incinerator.
  • this basket consists, inter alia, of a fiberglass envelope. Ashes from combustion can be melted in the oven, in a bath of molten glass. In this case, the basket consisting in particular of the fiberglass envelope containing the ashes or residues from the waste combustion will be dissolved in the glass bath.
  • the first embodiments use a light metal structure to stiffen the basket.
  • this metal structure is made by a grid.
  • said metal light structure is external and an inner envelope made of glass fibers is placed inside the light metal structure.
  • a second embodiment provides that it is the envelope made of glass fibers which is external and the internal light metal structure and therefore placed inside the fiberglass envelope.
  • the glass fibers constituting the envelope are woven, the weaving having a mesh size defining a porosity adapted to the type of waste, in order to thermochemically control the pyrolysis rate of this waste.
  • the light metal structure is made of wire mesh whose son are integrated in the weaving of the fibers, thus forming a single envelope.
  • a second main object of the invention is a vitrification process of waste in a waste vitrification incinerator.
  • the fiberglass basket containing the residues of the waste combustion is dissolved in the glass bath.
  • the concept according to the invention consists in placing the bag of waste to be incinerated in a basket consisting for the most part of non-woven or woven fiberglass, more or less tightly.
  • the tightening of the glass fiber (s) makes it possible to manage the contact between the contained waste and the hot and oxidizing atmosphere inside the incinerator, the weaving allowing for more or less significant heat and gas exchange.
  • the basket is preferably stiffened by a light metal structure.
  • non-combustible fiberglass with a high melting point enables the mechanical transfer of the waste bag from the airlock introducing waste into the incineration zone, avoiding any loss of contents of the basket during the transfer.
  • the contents of the basket namely waste, gradually heat up.
  • This rise in temperature leads to the pyrolysis of organic matter.
  • the pyrolysis gases escape from the basket to burn in the oxidizing atmosphere of the furnace.
  • the choice of the fiberglass envelope constituting, inter alia, the basket, its porosity and weaving more or less tight slows thermal transfers to the inside of the basket and gas transfers to the outside.
  • the mesh size of the weave is adapted to the type of waste. This makes it possible to manage the rate of pyrolysis and combustion of the waste contained in the basket. This minimizes the size of the gas puffs generated by the sequential introduction of whole bags of waste into the incinerator.
  • the porosity of the fiberglass envelope constituting the basket also makes it possible to minimize ash discharges and non-volatile toxic elements in the gases prevailing inside the incinerator. This porosity can therefore be adapted to the size of the solid toxic particles that must not be entrained in the gases.
  • the envelope 10 consisting of fiberglass is placed inside the light metal structure 12.
  • the latter is welded to the base of the basket which is advantageously constituted by a 18
  • the grill advantageously constituting the light metal structure 12 is preferably cylindrical and is welded, in its upper part on a metal tube 16 for stiffening.
  • the dripping pan 18 forming the base of the basket is intended to collect any drops of metal, or other melted materials, if the waste contains this type of low melting point material, which could melt prematurely in the airlock for example (in another type of embodiment the broiler pan could be made of tightly woven glass fibers so as to be virtually liquid-tight).
  • the entire basket is completed by a gripping handle 14 fixed in this embodiment on and above the metal tube 16.
  • the inner diameter of the fiberglass shell 10 is about 500 mm and is about 750 mm high.
  • the weight of the casing is of the order of 1 kg for a fiberglass woven at 45 ° and weight per unit area equal to 600 g / m 2 .
  • the broiler pan 18 is preferably made of stainless steel and of a thickness of the order of a millimeter.
  • the mesh constituting the light metal structure 12 is a stainless steel wire with a diameter of between 2 and 5 mm.
  • the external dimensions important for the handling of the basket in the airlock and in the incineration zone are fixed by the light metal structure 12 used.
  • the second embodiment according to the proposed invention uses a fiberglass shell 20 placed outside the metal light structure 22.
  • the latter also consists of a cylindrical wire mesh welded at the top to a metal tube 26 which is surmounted by a gripping handle 24.
  • the base of the assembly is constituted, preferably by a dripping pan 28 which can be placed inside the casing 20 fiberglass. In this embodiment, filling the basket with waste is facilitated.
  • the wires of the mesh constituting the light metallic structure 52 are integrated into the fiberglass weave constituting the envelope 50.
  • the broil pan 58 can then be placed inside or outside the envelope 50 made of fiberglass. glass.
  • the glass fibers constituting the envelope pass alternately on both sides of the wire mesh constituting the light metal structure 52. This difficult to achieve version brings, however, the advantages of the two previously described embodiments.
  • the basket comprises two layers of glass fiber 30A and 30B placed one inside the other.
  • the outer layer 30A has the primary function of filtering the pyrolysis gases vis-à-vis the dust.
  • the inner layer 30B has the primary function of containing the waste with the appropriate strength properties. It is reported that the function or position of the two layers can also be reversed.
  • These two layers 30A and 30B are preferably separated.
  • the light metal structure 32 is then placed between these two layers 30A and 30B. Fixing these three elements 30A, 30B and 32 relative to each other can be done by sewing with glass fibers or wire.
  • the incineration process according to the invention therefore uses the basket mentioned above to incinerate waste inside an incinerator for a period greater than pyrolysis and combustion of waste without a basket of at least fifteen minutes ( incineration time multiplied by three or ten depending on the basket).
  • the waste is thus placed above a bath of molten glass surmounted by a combustion zone under an oxygen atmosphere diluted in argon and heated by an arc plasma transferred between two electrodes.
  • the time noted 16:45 the duration of the pyrolysis and combustion is then very short, that is to say say of the order of 3 minutes and the oxygen supply is insufficient to ensure complete combustion of the puff of pyrolysis gas. Indeed, it remains a carbon monoxide content of about 3 to 4% in the reactor outlet gas.
  • the waste is kept suspended above a bath of molten glass time noted 15:42. Its burning time is increased to 17 minutes until time noted 15:59. This makes it possible to obtain complete combustion without the presence of carbon monoxide in the outlet gases of the reactor.
