Definitions
- the different stages of mineral wool production generate a certain amount of waste.
- This waste can come for example from the cutting of products, and then contain significant amounts of organic materials such as resins called “binders" and intended to ensure the mechanical cohesion of the fibrous mat, and possibly large amounts of water.
- biners organic materials
- Other types of materials may be associated with mineral fibers, for example paper films, aluminum-based or bituminous, elements of wooden pallets ...
- the specific output is defined as the kilogram output, expressed in tons of treated waste per day, relative to the melting area in m 2
- the specific output is defined as the kilogram output, expressed in tons of treated waste per day, relative to the melting area in m 2
- the specific output is defined as the kilogram output, expressed in tons of treated waste per day, relative to the melting area in m 2
- the formed glass is reduced (is characterized by a "redox" high, close to 1), which requires the use of oxidizing agents during its subsequent use as cullet (generally in contents ranging from 20% of the batch).
- Redox is defined here as the molar content of ferrous iron of the glass relative to its molar content of total iron. This term reflects the redox state of glass, which greatly influences the physicochemical properties of glass. The present invention therefore proposes to improve this process, thus to increase its specific pull without increasing the temperature of the walls and the vault, and to reduce the redox of the formed glass.
- the invention firstly relates to a waste treatment method, in particular from the production of mineral fibers, comprising a step of melting a mass of waste by adding to said mass of pure oxygen waste or d oxygen-enriched air through feed means, for forming a mineral material suitable for use as a vitrifiable raw material in a glass-melting process, characterized in that in addition energy through at least one burner immersed under the mass of waste and in that said means for supplying pure oxygen or oxygen-enriched air are disposed on the support of said mass of waste.
- combustion gases of at least one burner immersed in the mass of waste are thus discharged directly (the combustion gases are then emitted within the mass of waste) and / or indirectly (the combustion gases are not emitted directly into the waste mass but later develop within the mass).
- burner is also meant a device providing at least one oxidant and at least one gaseous fuel in which, or directly at the end of which, these reactants are mixed so as to create a reaction exothermic combustion. This excludes devices sometimes qualified as burners while they only provide one or the other reagents (fuel or oxidant).
- oxygen or oxygen-enriched air means devices, such as injectors, nozzles or, more simply, orifices, opening into the mass of waste and serving exclusively to supply said mass of feed directly.
- waste with pure oxygen or with oxygen-enriched air oxygen leading directly into the mass of waste, the supply of oxygen or oxygen-enriched air is thus directly within this mass of waste, which allows a very homogeneous distribution of the oxidizing gas.
- These supply means are therefore distinct from the submerged burners, the present invention implementing the combination of the two means that are oxygen supply means or oxygen enriched air on the one hand, and the or each submerged burner of 'somewhere else.
- These feed means are arranged on the support of the waste mass to be treated, said support preferably being substantially horizontal.
- a second particularly surprising advantage of the process according to the invention has been observed by the inventors. It has been found that a supply of energy by means of at least one submerged burner, instead of increasing, as one might expect, the temperatures of the oven, on the contrary decreases these same temperatures; which helps to significantly increase the life of the oven.
- the lower temperature of the furnace indeed has the advantage that the infiltrations of glass in the interstices of the furnace refractories are less important, the infiltrated melt solidifying faster because of the lower temperature and blocking the gap at a lower level. closer to the inside of the oven. It can be considered that this effect is a corollary of the effect of increasing the specific output: the embankment of fibrous materials is transformed more rapidly into molten material, the latter then evacuates energy more quickly.
- the melting point (measured at the level of the roof of the furnace) is advantageously less than 1200 ° C., or even less than or equal to 1150 ° C. Obtaining such low temperatures may result in the possibility of constructing the furnace of less efficient refractory materials and therefore substantially less expensive.
- the immersed burner (s) is advantageously controlled so as to keep the mass of waste in the form of a stable slope above the burners.
- the presence of a single burner above the top of the embankment of fibrous materials may, for example, result in the destabilization of said embankment, the burner may then be found in the open, resulting in poor heat transfer to the waste. fibrous and possible heating of the vault and / or walls of the oven.
- the geometry of the burner may be that described in EP-A-0 966 406 or an equivalent geometry.
- the burner can thus be composed of a cooling system of the water box type and a central duct fed with combustible gas of the natural gas type (or other combustible gas or fuel oil) around which is or are arranged (s) concentrically a or several conduits supplied with oxidant (for example oxygen), all these cylindrical section conduits coming into the nose of the burner.
- the waste introduced is generally composed of glass fibers whose composition may be of the type described in document EP 412 878.
- the content of binding organic materials (resins) is generally of the order of 5 to 10%, expressed by weight. dry relative to the total weight of the fibers. They may contain a variable content of other materials (primer films, packaging materials ).
- the invention also relates to a device adapted to the implementation of the method described above.
- This device is an oven comprising a vessel made of refractory materials forming a sole, walls and a vault, further comprising a support for the fibrous waste slope on which are arranged means for supplying pure oxygen or oxygen-enriched air. , and at least one submerged burner disposed on the floor and / or on a wall.
- the support is preferably substantially horizontal.
- the waste carrier may be the sole of the oven.
- a second embodiment of the device according to the invention is to support the fibrous waste by a grid located above the sole.
- This grid is advantageously a grid of metal material cooled by water circulation. It may for example be constituted by tubes comprising two cylindrical and concentric ducts, an internal duct supplied with oxygen and an external duct serving for cooling by circulating water, connections being arranged at regular intervals in the internal duct to supply food. oxygen furnace. This guarantees a supply of pure oxygen or oxygen-enriched air directly into the mass of waste.
- the molar ratio O 2 / CH 4 is preferably greater than or equal to 2, especially greater than or equal to 2.1, or even greater than 2.2, to ensure a reduction of redox.
- the formed glass may be considerably more oxidized than in the embodiment in which the sole constitutes the support of the fibrous waste slope.
- FIGS. 1a and 1b illustrate cross-sections in vertical and horizontal planes respectively of an implementation device of the "Oxymelt" process as described by patent document EP-A-0 389 314.
- FIGS. 2a and 2b illustrate sections in vertical and horizontal planes respectively of an embodiment of the device for implementing the method according to the invention.
- FIG. 3 illustrates a section along a vertical plane of a second embodiment of the device for implementing the method according to the invention.
- the overhead burners 10 are also in operation in order to increase the output of the device thanks to an additional energy input, the fibrous mass thus gives rise to a melt which flows in the form of a thin film having a viscosity of 100 1000 peas to the outlet 7 of the furnace to flow into the flow orifice at the base of said outlet 7, simultaneously, the combustion gases and fumes are discharged through the chimney 6.
- Such an industrial device has a surface area of 3m 2 capable of treating 18 tonnes of waste from glass wool production daily, thanks to an oxygen supply of 250Nm 3 per hour and an energy input of 20OkW. by means of the two overhead burners 10.
- the oven temperature (measured in vault) during normal operation is 1230 ° C.
- Figures 2a and 2b show an embodiment of the device according to the invention. Air burners 10 are no longer present. Three submerged burners 1 1 are however arranged on the hearth 3 of the oven. These three burners 11 are substantially symmetrically arranged with respect to a vertical axis meeting the top of the embankment of fibrous materials 9.
- the device according to the invention makes it possible to implement a process that differs from the process known from EP-A-0 389 314, and described above, by the absence of energy supply by means of overhead burners 10 and by the step in which the submerged burners can increase the specific pull while decreasing operating temperatures.
- the addition of the three submerged burners 11 placed on the hearth 3 of the furnace makes it possible to increase the quantity of treated waste to 24 tons per day, ie an increase of approximately 33%, for a power of 24OkW.
- Air burners are no longer used, the energy consumption has increased little compared to the non-sophisticated device.
- the temperature of the oven decreased significantly from 1230 ° C to 1150 ° C. Oxygen consumption has decreased by 30%.
- the control of the furnace can be carried out by regulating the oxygen content of the fumes at the furnace outlet, which can be measured at the level of a smoke evacuation zone.
- the oxygen content of the fumes is regulated to 15% by volume.
- FIG. 3 illustrates a second embodiment of the device according to the invention.
- the fibrous waste slope 9 is here supported by a metal grid 12 allowing the flow of molten material.
- This grid 12 also replaces the injectors 8 in that it constitutes the oxygen supply means for the combustion of organic products contained in the waste.
- the submerged burners 11 open at a distance below the lower level of the slope, so that a glass bath is located above the submerged burners 1. combustion gases are therefore not emitted directly within the waste mass, but are developing later within said mass.
- the residence time of the glass in this device can be substantially increased with regard to the first embodiment of which the implementation device is illustrated in FIG. 2, and the redox of the glass can be modulated by a modification of the molar ratio O 2. / CH 4 .
