  • thermolysis thermolysis
  • thermolysis solids there may be mentioned, for example, the German patent DE 4308551 or the French applications FR 2 679 009 and FR 2 678 850 both filed in the name of the applicant.
  • German document DE 4308551 has the characteristic of gasifying the fine carbon-rich fraction of solid residues in order to produce a synthesis gas and slag from fusion.
  • thermolysis oven hot gas treatment, in the thermolysis oven itself, can be carried out; this allows the pyrolysis gases to be reused directly, without further treatment. More particularly according to this document, the pyrolysis gases are used to heat, directly or indirectly, the waste.
  • thermolysis process in terms of the implications for the gaseous or solid discharges it generates.
  • Increasingly stringent environmental standards planned or already in force in most industrialized countries, force operators to install less and less polluting installations. Releases of N0 x and MCI, HF, SO2, Co, fly ash, clinker, etc. are in particular subject to increasingly strict standards.
  • thermolysis products namely either the gaseous effluents or the solid products.
  • the object of the present invention is to remedy these drawbacks. In particular, it allows better recovery of the energy content of waste.
  • the present invention makes it possible to minimize the self-consumption of energy necessary for carrying out the method.
  • thermolysis gases can be burned at least partially as fuel either in the cyclone hearth or in at least one of said energy recovery means.
  • the post-treatment essentially consists of a purification of the carbonaceous solids.
  • the method according to the invention can also consist in controlling the quantity of solid fuels burned in the cyclone hearth and the quantity of solid fuels stored, according to the energy balance.
  • the means for combustion of the thermolysis gases comprises said hearth-cyclone.
  • the means for combustion of the thermolysis gases and the means for recovering energy are arranged such that the combustion means are supplied with thermolysis gases and the means for recovering energy is supplied by the effluents from the combustion means and, under certain operating conditions, by hot gases from the cyclone hearth.
  • the solid post-treatment means can advantageously carry out a purification of carbonaceous solids.
  • the installation according to the invention may comprise a means of filtering the fumes from the energy recovery means 11, an outlet of said filtration means being connected to an inlet of the cyclone hearth.
  • the referenced raw waste (DB) can first of all undergo a pretreatment, the complexity of which depends on the type of waste treated, and which uses traditional techniques: grinding, partial sorting, de-wire removal, drying, etc. ...
  • the purpose of this pretreatment step is to recover easily separable and recoverable materials, and to homogenize the waste.
  • This part of the installation does not in itself have an innovative character since the techniques used have long been used in the waste industry.
  • This pre-treatment has no advantage of a mandatory nature.
  • the pretreated waste (DP) is introduced into a rotary kiln 1 with indirect external or internal heating by means of a device 2 making it possible to guarantee the tightness of the furnace with the outside and of thus prevent any entry of air into the oven.
  • the device 2 which makes it possible to achieve this seal can be an Archimedes screw, or else a system for introducing the load by compacted bundle.
  • the rotary kiln may be such as that disclosed in the French patent application EN. 94/06660, with indirect internal heating.
  • waste undergoes thermal degradation to result in the formation of a gas phase (GT) and a solid residue rich in carbonaceous matter (SC).
  • GT gas phase
  • SC carbonaceous matter
  • Waste and gases from their thermal decomposition circulate cocurrently in the oven. This operation is carried out at a temperature between 200 and 800 ° C and preferably between 350 and 600 ° C.

  • thermolysis allow the retention in carbon solids of almost all of the acid gases, in particular hydrochloric acid produced during the thermal decomposition of chlorinated plastics such as PVC.
  • This self-neutralization of the acid components by basic materials always present in the waste is favored, among other things, by the reducing atmosphere as well as the low temperatures to which the waste is subjected during thermolysis.
  • the yield is improved of capture of acid gases by carbonaceous solids.
  • the purification of carbonaceous solids which is described below makes it possible to eliminate in particular the chlorine salts resulting from the capture of acid gases.
  • the processing temperatures being low and the thermolysis being carried out away from oxygen, the heavy metals are neither volatilized nor oxidized, and therefore remain concentrated in carbonaceous solids (SC).
  • the carbonaceous solids (SC) are evacuated by a device 4 guaranteeing tightness with respect to the outside (rotary valves, airlock with guillotine valves, or any other equivalent device making it possible to perform this function ).
  • the carbonaceous solids (SC) are conveyed to a purification device 6 which aims to separate part of the inert materials and to eliminate the soluble pollutants, in particular the chlorine salts, present in the carbonaceous solids.

  • the excess fraction (GT2) of the thermolysis gas can be directed to a combustion device, for example the cyclone hearth with molten ash 5.
  • the cyclone hearth with molten ash 5 is a hearth suitable for the combustion of solid fuels heavily loaded with ash at low melting point. It is characterized by a high turbulence and a rotation of the flow, which makes it possible to obtain a long residence time of the fuel and a good retention of the ashes. It operates at temperatures of the order of 1000 to 1500 ° C. At these temperatures, the ash melts and flows in the molten state out of the reactor.
  • the interior of the cyclone hearth 5 can preferably be covered with a refractory ceramic coating capable of withstanding temperatures of the order of 1500 ° C.
  • the injection of purified carbon solids (SCE) is done pneumatically by one or more tangential rectangular or circular inlets distributed over a perimeter of the cyclone. It is also possible to inject into one or more of these inlets a supplement of combustion air and / or all or part of the excess of the thermolysis gas GT2.
  • other tangential inlets can be installed in order to carry out additional injections of combustion air or gaseous fuel like all or part of the excess of the thermolysis gas GT2.
  • an additional air injection can be performed at the upper outlet of the cyclone hearth, in order to improve the combustion efficiency.
  • the combustion in the cyclone hearth with molten ash is optimized so as to minimize the emissions of gaseous pollutants.
  • the sharing of combustion air between the various inlets will therefore be carried out so as to ensure total combustion of the purified carbon solids and of the thermolysis gas, and to minimize the formation of nitrogen oxides and unburnt materials.
  • the cyclone hearth with molten ash advantageously makes it possible to immobilize the elements definitively pollutants present in purified carbon solids, in particular heavy metals, by trapping in the vitreous matrix formed during the melting of the mineral matter contained in the purified carbon solids.
  • the temperatures obtained during the combustion of purified carbon solids (SCE) and the excess of the thermolysis gas GT2 are sufficient to melt these mineral materials.
  • the ashes thus melted (CF) flow out of the hearth 5 and fall into a water tank 10 where they are cooled. As they cool, the ashes form solid aggregates. These aggregates are inert with respect to leaching, which allows them to be recycled and reused in road applications or public works, for example.
  • the hot fumes (F) from the mixed combustion of purified carbon solids and part of the thermolysis gases in the cyclone hearth 5 are then directed to an energy recovery device 11 such as a heat exchanger, a boiler producing steam or hot water, or a boiler coupled to a turbine to generate electricity. Then these fumes are dusted in a device 12 which can be a bag filter or an electrostatic dust collector, and returned to the atmosphere via an extractor 13 and a chimney 14 via a line 35.
  • the ashes from respectively of the energy recovery device 11 and of the dust collector 12 are mixed with the purified carbon solids and then sent to the cyclone hearth 5 via lines 36 and 37 respectively.
  • the ashes are vitrified in the cyclone hearth 5, thus allowing the inerting of the pollutants adsorbed on this dust.
  • thermolysis gas part of the thermolysis gas (GT1) is used to heat the rotary kiln by combustion, for example in burners located in the double jacket 3 surrounding the rotary kiln 1.
  • GT1 part of the thermolysis gas
  • GT2 excess fraction
  • the burner and combustion chamber configurations make it possible to minimize the formation of nitrogen oxides during the combustion of the thermolysis gas, and guarantee the destruction of all organic compounds thanks to a gas residence time of at least minus 2 seconds at 850 ° C.
  • the purified carbon solids (SCE) are burned in a cyclone hearth with molten ash 5 of a design identical to that described above but of lower thermal power, mixed with the ash from the device for removing dust from the fumes 12 and from the energy recovery device 11.
  • the temperature reached during the combustion of purified carbon solids is sufficient to allow the ash to melt and therefore trap the pollutants in the vitreous matrix.
  • the molten ash (CF) flows into a tank of water 10 where it is cooled and solidified so as to produce inert aggregates.
  • the combustion air is staged as described above and all or part of this air can also be preheated in order to improve the thermal balance of the operation.
  • the hot fumes (F) from the combustion of thermolysis gases (GT2) in the combustion chamber 15 and those from the combustion of purified carbon solids (SCE) in the cyclone hearth 5 are mixed and sent to a recovery device energy 11 such as a heat exchanger, a boiler producing steam or hot water, or a boiler coupled to a turbine making it possible to produce electricity. Then these fumes are filtered in a device 12 and returned to the atmosphere via an extractor 13 and a chimney 14. The ash and dust from the energy recovery device 11 and the dust collector 12 are mixed with the purified carbon solids then sent in the cyclone 5 hearth in order to be vitrified, thus allowing the definitive inerting of the pollutants adsorbed on this dust.
  • a recovery device energy 11 such as a heat exchanger, a boiler producing steam or hot water, or a boiler coupled to a turbine making it possible to produce electricity.
  • these fumes are filtered in a device 12 and returned to the atmosphere via an extractor 13 and a chimney 14.
  • the embodiment of the invention according to FIG. 2 has a more flexible operation than that according to FIG. 1.
  • the purified carbon solids (SCE) are not sent to the hearth-cyclone 5, but stored.
  • the cyclone hearth 5 operates as indicated above. The stored fuels can then be burned during this period.
  • This embodiment of the invention therefore allows a very good match between the energy demand and the need.
  • the device for purifying carbonaceous solids 6 as shown in FIG. 3 will now be described.
  • the carbonaceous solids (SC) are evacuated via a sealed device 4 and fall by gravity into a stirred tank 16 filled with water at room temperature, which allows the solids to cool.
  • the agitation of the mixture ensured for example by rotation of a shaft carrying blades 17, is such that the heaviest particles composed essentially of metals, mineral matter or glass, are deposited at the bottom of the tank, while the lighter carbon-rich particles are kept in suspension.
  • the bottom of the tank 16 can be immersed a screw, a mat, a scraper or any other equivalent device 18 allowing the continuous extraction of the mineral matter deposited at the bottom of the tank.
  • This first tank 16 therefore allows the cooling of carbonaceous solids as well as the separation of part of the mineral matter contained in the carbonaceous solids.
  • the inert mineral materials extracted by the extraction device 18 are then rinsed with water on a vibrating screen 19 surmounted by a water spray boom 20, in order to remove the carbon particles deposited on these materials mineral.
  • the rinsing water contaminated by these carbon particles can be sent by a pump 21 to the first settling tank 16.
  • the water-carbonaceous solids mixture suspended in the tank 16 is taken up by a pump 22, then sent to a second perfectly agitated washing tank 23 containing water maintained at a temperature between 40 and 95 ° C., and preferably between 75 and 85 ° C.
  • This temperature is kept constant in the tank 23 thanks to a temperature regulation 24 connected to an electrical resistance or to any other equivalent device making it possible to maintain the temperature of the water at a set value.
  • the residence time of the carbonaceous solids in the tank 23 is between 15 and 120 minutes.
  • the water / carbonaceous solids mass ratio is between 1 and 100 and preferably between 5 and 15. This operation essentially solubilizes the chlorinated salts formed during the thermolysis step. Heavy metals are not dissolved and remain concentrated in carbonaceous solids.
  • the carbonaceous solids Before their introduction into the agitated tank 23, the carbonaceous solids can be ground in a mill 25 operating in the liquid phase, in order to reduce the average particle size of the carbonaceous particles and to accelerate the washing step. This step can also be followed by a separation step on a calibrated sieve 26 making it possible to separate the aluminum sheets contained in the carbonaceous solids (SC). This operation is particularly necessary when the carbonaceous solids come from the thermolysis of household waste. A spray of water 27 is maintained on the sieve containing the aluminum sheets in order to remove the carbon particles deposited on the surface of these. This last operation makes it possible to recover the aluminum sheets which can then be recycled and recovered.
  • SC carbonaceous solids
  • the water-carbon solids suspension is taken up by a pump 28 and then directed to a filtration device 29 which aims to remove the water loaded with chlorides from the carbon solids.
  • This operation can be carried out with a centrifuge, a vacuum belt filter, or any other filtration device making it possible to separate water from carbonaceous solids.
  • the dry purified carbonaceous solids, or containing no more than a reduced amount of moisture are stored in a silo 30.
  • the waste water from the filtration is directed if necessary to a treatment device of water 34 making it possible to precipitate the chlorinated salts, then reinjected into the first settling tank 16.
  • An addition of new water is carried out permanently using the devices 20 and 27.
  • the decanting and washing steps as described above can be carried out in the same tank, simultaneously fulfilling the functions of tanks 16 and 23, the temperature of which is maintained between 40 and 95 ° C.
  • the previous device is then simplified.
  • the present invention allows the recovery of the energy content of waste through the production of a solid fuel and a purified gaseous fuel, and their combustion.
  • the device 6 for purifying carbonaceous solids according to the invention makes it possible to eliminate part of the mineral matter and to recover recoverable materials such as aluminum.
  • This device also makes it possible to increase the quality of the fuel produced, by reducing its ash rate and its content of pollutants. Finally it increases its calorific value.
  • the waste treatment method according to the invention makes it possible to avoid the dispersion of pollutants, since almost all of the pollutants are concentrated in carbonaceous solids. Part of these pollutants is then eliminated by the purification treatment of carbonaceous solids, the other part being immobilized in the inert granules resulting from combustion in the cyclone hearth with molten ash.
  • the invention relates to the production of a complete waste treatment system which suppresses pollutant emissions in the fumes from the combustion of thermolysis gases and carbonaceous solids, so that the only smoke treatment to be used is a simple dusting.
  • the invention therefore makes it possible to avoid installing smoke treatment devices by washing, which reduces the cost of waste treatment compared to that of conventional techniques such as incineration.
