Definitions

the invention relates to a method and an installation for treating urban and / or industrial waste.
Pyrolysis consists of burning a solid with a certain lack of oxygen. Oxygen is used in this reaction to heat the product and to decompose the materials in combustible gases, smoke and combustible carbonaceous residues, such as charcoal.
thermolysis reaction is even higher than that of pyrolysis because we are in the presence of a phenomenon of distillation of organic matter. During this reaction, the heat no longer comes from a direct flame but from radiation from a heating chamber.
thermolysis reaction When a thermolysis reaction is carried out on urban and / or industrial waste, we will somehow carry out a distillation of these to finally obtain carbonaceous solids recoverable and recoverable after sorting of inert, tars recoverable and recoverable in specific petrochemical plants, as well as clean combustible gases that can also be reused. So far, laboratory tests of thermolysis and some Experiments promise an interesting future for the treatment of urban and / or industrial waste, but no process or treatment facility has yet emerged, allowing certain economic industrial development.

Another object of the present invention is to provide a process which allows the production of installations for treating urban and / or industrial waste, which are modular in their capacity and which can be easily adapted according to such or such uses.
Another object of the present invention is to provide a method and an installation for destroying urban and / or industrial waste which are advantageous in terms of the recovery of the material which can be stored and then checked before reuse.
Another object of the present invention is to provide a method and an installation for treating urban and / or industrial waste which are particularly advantageous from the ecological point of view and which make it possible to provide a solution to the problem of pollution of incinerators, well known to date.
the process for treating urban and / or industrial waste, by which the waste is subjected to a thermolysis reaction is characterized in that: - the waste to be treated is previously dehydrated in a closed drying enclosure, - all the gases produced during drying are recovered, in a closed circuit with respect to the atmosphere, and these gases are subjected to a purification step, - Said purified gases are at least partially reinjected into the installation as a drying agent and the non-polluting excess gases are discharged to the outside.
thermolysis reaction is carried out at low temperature, of the order of 400 to 450 ° C., in a thermolysis chamber, isolated and controlled, then the gaseous products obtained from the thermolysis reaction, in closed circuits relative to the atmosphere, in which the gaseous elements are separated tars in the gaseous state, then the combustible gases are purified with a view to their subsequent re-use in said process.

the invention relates to a method and an installation for treating urban and / or industrial waste, which in particular allow destruction of such waste in a non-polluting and economical manner using a thermolysis reaction.
thermolysis consist of carbonaceous solids recoverable and recoverable after sorting inert, tars also recoverable and recoverable in specific thermal or petrochemical installations as well as clean gases reusable in the process of the invention after inspection.
the waste is subjected to a fully controlled thermolysis reaction, in which in particular the creation at high temperature of chlorinated compounds and stable pollutants difficult to remove, such as dioxide, is avoided, and then the products obtained by implementing different stages carried out successively and sequentially, without discharge polluting the atmosphere.
the waste to be treated Prior to the thermolysis reaction, according to the present invention, the waste to be treated is dehydrated in order to eliminate a large part of the moisture contained in it.
This prior dehydration is carried out in a closed drying enclosure and this phase is completely controlled since all the gases produced during drying are recovered, in a closed circuit with respect to the atmosphere, and these gases are subjected to a purification step.
said purified gases are at least partially reinjected into the installation as a drying agent.
it is necessary to evacuate the excess gases because for example it is necessary to enter the installation of the combustion air.
this discharge to the outside is carried out in a non-polluting way because the excess gases are not aggressive for the atmosphere.
thermolysis is advantageously carried out at a temperature below 450 ° C. to avoid the formation of dangerous pollutants such as, for example, dioxide.
thermolysis reaction is carried out in a thermolysis chamber, isolated and controlled, from which the gaseous products resulting from the thermolysis reaction are recovered, in closed circuits with respect to the atmosphere.
the recovered gaseous products, resulting from the thermolysis reaction, are then also treated in closed circuits in which the combustible gaseous elements are separated from the tars in the gaseous state, then the combustible gases are purified with a view to their subsequent use in said process, i.e. separating the droplets from the gas before storage.
thermolysis reaction can be carried out at atmospheric pressure.
thermolysis reaction under sweeping neutral gas for the reaction, in the thermolysis chamber, at a controlled pressure slightly higher than atmospheric pressure.
thermolysis gaseous products resulting from thermolysis are continuously removed from the thermolysis chamber and directed to the means for recovering and treating said gaseous products.
thermolysis chamber In the case where the reaction is carried out under neutral gas sweeping, such a gas is blown into the thermolysis chamber at a pressure slightly higher than atmospheric pressure, for example of the order of 1.6 bar, which continuously flushes out gaseous products from thermolysis.
thermolysis reaction In the case where the thermolysis reaction is carried out under overpressure, it is the pressure prevailing inside the thermolysis chamber which will drive the gases resulting from the thermolysis out of the enclosure as a function of a calibration pressure. predetermined.
thermolysis step proper the temperature in the thermolysis chamber is established, indirectly with respect to the waste to be treated, by circulation of high temperature heating gas.
these heating gases are recovered, in a closed circuit with respect to the atmosphere, and these gases are subjected to a purification step, in the same way as the gases produced during the preliminary drying.
the purified gases are at least partially reinjected into the installation as a drying agent.
the purified excess gases therefore non-polluting, can be evacuated outside the installation.
One of the advantages of the process of the present invention is that it allows continuous treatment of the waste.
the waste is dehydrated in a drying chamber, in which it is stirred and subjected to a flow of hot air, such that a movement of the waste from the inlet to the outlet of said said is defined. drying chamber.
thermolysis reaction proper is carried out, as has been specified above.
thermolysis phase When the waste to be treated has undergone the thermolysis phase, it is then removed by gravity and sequentially solids from thermolysis for recovery.
FIG. 1 shows an example of an installation for treating urban and / or industrial waste, capable of carrying out a thermolysis reaction and designed particularly for the implementation of the method of the invention which has just been described.
thermolysis chamber controlled and isolated, waste to be treated
means for recovering solid materials and gaseous products. from thermolysis.
the drying chamber (1), the thermolysis chamber (2) and the means (3) for recovering the materials are advantageously arranged successively in series in such a way as to allow a continuous, sequential gravity movement of the waste and the contained materials, from the inlet of the installation (5) to its outlet (6) and that the 'We can keep each chamber (1, 2, 3) stable operation in temperature and / or pressure.
the first phase of the actual treatment therefore consists of a phase of drying or dehydration of the waste.
This phase is carried out in the drying chamber (1) in which the waste is stirred and subjected to a flow of hot air.
an advance movement (7) of the waste is generated from the inlet (5) to the outlet (8) of said drying chamber (1).
the drying chamber (1) consists of an enclosure (9) closed, having an inlet (5) through which the waste to be treated is introduced and an outlet (8) from which the dehydrated product will drain out.
a motorized drum (10) Inside the closed enclosure (9) is provided a motorized drum (10) able to contain the waste to be dried and to brew it permanently, and also able to create said advance movement (7) for the waste from the inlet (5) to the outlet (8).
the installation comprises means (12, 13) for creating a stream of hot air able to circulate in said drying enclosure (9).
a treatment box (12) which comprises a gas burner (13) and a blowing system (47) placed upstream of the burner (13), and able to direct a gas flow towards the flame of said burner.
the drying circuit also includes means (48) for recovering the gaseous fluid resulting from the drying of the drying chamber (9) as well as means for purifying said gaseous fluid resulting from drying.
the hot dry air (11) introduced into the dryer absorbs, on contact with the stirred waste, the moisture contained in it and thus leaves charged with moisture in (16).
This moist air (16) recovered by the means (48) then passes through a condenser exchanger (17) in order to be dehumidified and before being recycled to the means (12, 13) to create said stream of hot air, at the inlet (15) of the air treatment box (12) so that it is purified.
said means for creating the stream of hot air and for purifying the gaseous fluid consist essentially of the burner (13) and the blowing system (47).
a burner will be provided, the flame of which advantageously reaches at least 850 ° C. and a blowing system, the speeds of which will be such that the said gases will pass through the flame and will be maintained at this temperature for at least two seconds.
a sterilization of the gases will be obtained which will therefore be purified and the aromatic essences which they contained will be burned.
a valve (50), installed on the discharge of high temperature excess gases (19), before the recovery battery (18), will allow the adjustment of the volume of air entering compared to the volume of air leaving.
the direction of circulation of the hot air flow (11) is opposite to said advance movement (7) of the waste in the dryer.
the drum (10) is placed in said stream of hot air and provision is made for its rotation and its arrangement so that the hot air is introduced countercurrently into the dryer.
said drum (10) is arranged horizontally with its inclined axis of rotation to allow movement (7) of the waste from the inlet (5) to the outlet (8) of the dryer.
the drum (10) will internally have blades (49) fixed on the latter.
thermolysis reaction is carried out in the thermolysis chamber (2).
this thermolysis chamber (2) is constituted by a double jacket reactor having an internal primary enclosure (21), fixed, into which the waste is introduced, and by a secondary external heating enclosure (22), fixed, enveloping said primary enclosure (21).
a motorized rotor (23) equipped with paddles (24) oriented and fixed on a central axis controlled by a motor (25).
thermolysis chamber is horizontal; nevertheless, other arrangements could be envisaged, the rotor possibly being oblique, or even vertical. Likewise, a fixed enclosure and a rotating rotor are provided, but of course, one could imagine a reverse system in which the enclosure would turn.
the waste is heated up in particular by the combustion gases from a burner (28), of the mixed fuel oil - gas type for example, circulating in said secondary enclosure (22) which surrounds the primary enclosure (21).
This circulation of high temperature gas allows in particular the rise in temperature inside the enclosure (21) of the reactor of the order of 400 to 450 ° C.
the gases shown diagrammatically at (30) in the figure are reinjected into the drying circuit, as described above, thus participating in energy recovery. These gases are in particular reinjected at the inlet (15) of the box (12).
thermolysis chamber recovery heating gases which heat the thermolysis chamber, recovery which takes place in a closed circuit with respect to the atmosphere. Then these gases are also subjected to a purification step as it was for the drying gases.
drying (1) and thermolysis (2) chambers are superimposed, as shown in particular in FIG. 1, so that loading can occur by gravity.
an airlock (31) capable of connecting the two chambers in a sealed manner, so the waste can be introduced into the chamber thermolysis (2) continuously via said airlock (31) in order on the one hand to balance the pressures between the two enclosures and on the other hand, to authorize a neutralization of the incoming product, in particular by injection of nitrogen or pressure balance before opening the interior door of the airlock, or other.
thermolysis chamber there is another airlock (32) also sealingly connecting the thermolysis chamber and the means for recovering solid materials (3).
this second airlock (32) is similar to the first with regard to the evacuation of solids from thermolysis.
the waste is stirred inside the enclosure (21) of the reactor by the rotor (23-25).
the blades (24) define an advance movement (26) of the material contained in the chamber (2), from its inlet (8) to its outlet (27).
thermolysis according to the process of the present invention, the gaseous products resulting from the thermolysis reaction are recovered and treated in closed circuits (33) relative to the atmosphere as particularly illustrated in FIG. 2 .
the closed circuit (33) substantially constitutes said means (4) for recovering gaseous products resulting from thermolysis and are capable of separating the fuel elements from the tars in the gaseous state, by washing the combustible gases, with a view to their subsequent use. in said method.
these means (4) consist of a closed circuit (33) comprising at least one device for circulating said gaseous products such as a mechanical extraction device (34), a separator (35) "gaseous element fuel - tar in gaseous state ", of sprayer type, a gas purification circuit (36) in which the gas droplets are separated before its storage, as well as a circuit (37) for treating liquid effluents .
a closed circuit (33) comprising at least one device for circulating said gaseous products such as a mechanical extraction device (34), a separator (35) "gaseous element fuel - tar in gaseous state ", of sprayer type, a gas purification circuit (36) in which the gas droplets are separated before its storage, as well as a circuit (37) for treating liquid effluents .
thermolysis reactor (2) taking into account the temperature at which the reaction is carried out, there is a mixture of the combustible gaseous elements and of the tars in the gaseous state. These gases are removed under pressure or by sweeping the gas. In addition, certain powdery solid elements can also be entrained.
the principle of separation of combustible gases and tars leaving the reactor is carried out by the wet method using the separator (35) of the sprayer type generally known under the name of "quench at the water”.
the gaseous elements produced by the thermolysis reaction escape through the top (39) of the separator, the extraction device (34) making it possible to overcome the pressure drops in the circuit.
These gases are combustible and are then purified and stored in pressure tanks before being reused by the installation's burners.
This decantation is carried out in the treatment circuit (37) in which the light phase is continuously recovered by an oleophilic drum, then detached from the drum using a scraper which sends it in a small buffer capacity (40) , heated by an internal coil, in order to lower the viscosity of the organic mixture.
This mixture is then taken up by a gear then stored in a tar storage tank (41) before being redirected or treated.
the heavy aqueous phase is taken up at the bottom of the settling tank (37) by a centrifugal pump (42) then clarified on filters (43) intended to remove solid particles such as dust.
the decantation purge is then purified of any organic compound by passage over active carbon (44) and then discharged into the wastewater basin.
the washing liquid, used in the separator (35) of the sprayer type is recycled, kept at low temperature on the loop.
the on-line neutralization of the chlorine contained in the gas circuit is done by injection of soda (45) in the water of the "Quench".
the circuit is purged regularly to be sent to the settling tanks (37).
the solids resulting from thermolysis are removed by gravity and sequentially. This evacuation is, let us recall, carried out by means of the airlock (32) which makes it possible to maintain a controlled atmosphere inside the reactor (2).
thermolysis chamber (2) and the recovery means (3) are superimposed, the latter being in particular constituted by a container (46) adapted under said airlock (32).
a container (46) adapted under said airlock (32) it could also be possible to place them side by side with a lifting conveyor between them.
thermolysis solid residues from thermolysis, such as coals or inert materials, these being recovered from below the reactor (2) via the airlock (32), in particular neutralized by nitrogen injection.
a mobile, sealed, double-envelope container (46) is used, in which cold water is circulated in order to accelerate the cooling of the product.
a handling device with a magnetic drum to remove ferrous materials and a vibrating screen to isolate the inert parts of the carbon. All of this equipment will be provided in particular under a sealed hood in order to limit carbon dust and its expansion in the atmosphere.
urban waste is supplied in a main pit with an autonomy of several days of operation, but without however being exaggerated so as to minimize the release of odors.
the air volume located above the repository is maintained in depression by a mechanical ventilation assembly.
the waste thus prepared is then conveyed on a crusher allowing the ultimate physical transformation of the raw product before treatment.
the grinding will shred household waste into sufficiently small elements so as to facilitate the drying technique described above.
a belt conveyor assembly takes up the waste thus treated from the mill outlet to store it in a hopper with a capacity such that it can continuously supply the drying chamber (1) of the present invention.
thermolysis reaction The means for treating the gaseous products resulting from thermolysis which have just been described will in particular be adapted as a function of the conditions under which the thermolysis reaction is carried out, namely under atmospheric pressure or under CO 2 sweeping or under overpressure particularly to allow in the different processing circuits the circulation of the different products.
