    The invention relates to a method for processing molten material, in particular non-metallic melt such as slag, to amorphous material, in which the molten material is vitrified by cooling, the molten material being brought into contact with a metal bath for vitrification and then made as an amorphous material is applied to the metal bath and
    an apparatus for performing this method.
    Mineral melts, such as blast furnace slags, are usually vitrified with the aid of water by cooling in order to obtain an amorphous product which is in the glass phase, i.e. a metastable phase has solidified. After a grinding process, such a product can be mixed into various cements as a latently hydraulically active component. The heat of the melt is in such a procedure in low temperature heat
    transferred from water and can no longer be used.
    For the purposes of the present invention, non-metallic melts, mineral melts, blast furnace slag, steel slag are optionally mixed with S1i0; for lowering the basicity, artificial slags from marl, cement furnace bypass dusts, waste incineration slags, non-ferrous metallurgical slags, melting chamber slags from caloric power plants, alumina melting cement melts, old glass melts, artificial puzzolamolts, industrial dust melts, such as slag melts
    dried sewage sludge and the like understood.
    Mineral melts, for example sewage sludge sludge
    cck, must be extremely fast (about 10 ° K / sec) below them
    Recrystallization point (depending on the basicity between about 600 and 850 ° C) are cooled to obtain a cement-compatible amorphous and hydraulically active product. Below this recrystallization temperature, a much lower cooling gradient can subsequently suffice
    being found.
    In order to increase the slag glass content of the granules of amorphous material or amorphous granules and to improve the slag grindability compared to cold water granulation, WO 01/051674 A1 has proposed boiling water granulation in which the molten slag is introduced into cooling water provided at boiling temperature. As a result, the latent enthalpy of vaporization of the cooling water is immediately available for faster cooling, which maximizes the slag glass content. The granules surprisingly have a very low apparent density and float on the boiling water. This means that the slag grindability is significantly improved compared to grindability when using cold water granulation. The granulate itself is discharged from the boiling water at a temperature which exceeds the boiling point of the water, the adhesive water evaporating during the discharge of the granules, so that dry granules form immediately. Since water is only discharged together with the granulate in vapor form, there is no waste water problem. The steam is condensed and returned to the granulator together with make-up water to cover the water vapor losses. The by-products resulting from the slag-water reaction, e.g. H2S remain in the gas phase during the condensation of water and are present here in a concentrated form, so that
    an economically sensible refurbishment succeeds. Ande-

    on the one hand, the formation of a chemically highly contaminated vapor phase requires the provision of complex installation
    to treat the vapors appropriately.
    A method has become known from WO 2016/145466 A1 in which the cooling water granulation has been further developed in such a way that the cooling water for the separation and / or conversion of interfering substances, for example fluorine and chlorine compounds, alkalis, sulfur, heavy metals (for example Cr, V, Ni, Mo, Cu, Sn, Zn, Cd, Hg), rare earths, but also iron and free lime or unreacted CaO and MgO, an acid and especially sulfuric acid is added. The granulate obtained in this way has a particularly high reactivity and hydraulic activity and can therefore be used with great utility in the cement industry
    Find.
    However, the method according to WO 2016/145466 A1 is in need of improvement insofar as on the one hand the cooling effect of the aqueous cooling medium can be regarded as unsatisfactory due to the Leidenfrost effect and on the other hand the vapors produced during the granulation are not only toxic but also extremely corrosive. This goes hand in hand with increased requirements for exhaust air management with regard to environmentally relevant aspects and with regard to occupational safety.
    2 For example, JP 201406% 671 A discloses a method for cooling liquid slag, in which the melt is applied to a metal bath in order to vitrify it as quickly as possible on the surface of the metal bath to form a plate. The same is open in CN 105837041 A
    beard where a glass melt is cooled in a tin tank,
    to form an amorphous glass plate. All solutions of this type are related to the implementation of process engineering aspects
    counter that make them seem unsuitable.
    The invention is therefore based on the object of improving a method of the type mentioned at the outset such that, on the one hand, cooling is carried out as quickly as possible in order to obtain a highly amorphous product for use in the cement industry without chemically contaminated vapors and in particular no corrosive vapors arise, and on the other hand as stable, continuous as possible
    Operation of the method is made possible.
    To achieve this object, a method of the type mentioned at the outset is characterized in that the molten material is introduced into the metal bath via an open end of an immersion tube immersed in the metal bath and in the metal bath, preferably by means of a mechanical disintegrator, preferably a rotor, from the loading -
    range of the open end of the dip tube is promoted.
    The provision of a metal bath for cooling the melts has the advantage over the use of aqueous cooling media that no evaporation of the cooling medium occurs at the temperatures customary when processing melts such as blast furnace slag. Compared to the use of aqueous cooling media, which change to the vapor phase on the surface of the material to be cooled quickly (Leidenfrost effect), this results in a much better heat transfer from the melt to the metal as the cooling medium, so that an extremely rapid cooling takes place the recrystallization point of the melt takes place. The use of metal as a cooling
    dium is characterized by the fact that no or no
    noteworthy steam development can be observed and the method according to the invention can therefore be handled easily and can be implemented with little outlay in terms of plant technology. The invention is also particularly advantageous insofar as there is no risk of water vapor explosions in the water-free glazing and granulation process according to the invention. Characterized in that the melt is introduced into the depth of the metal bath by means of an immersion tube and is removed from the area of the open end of the immersion tube, that is to say it is conveyed out of the entry area, this being preferably in the sense of forced conveyance and more preferably by means of a mechanical disintegrator takes place, an extremely finely divided amorphous material is obtained as a product. In the depth of the metal bath, strong, sometimes turbulent flow conditions prevail due to the conveying work that is introduced into the bath to convey the amorphously solidified melts, so that the melt is exposed to strong shear forces. This leads to a strong comminution of the introduced melt, which can be further promoted by the preferably mechanically conveying of the amorphous material from the area of the open end of the dip tube. The melt, which cools rapidly in the metal bath, can no longer reach the region of the open end of the dip tube due to the conveying action, as a result of which the melt flowing in can be introduced constantly into the metal bath. The amorphous material formed from the melt will subsequently rise to the surface next to the dip tube through the metal bath and collect there due to the low density of the melt cooled in this way and thus granulated to amorphous material. With continuously flowing melt
    the amorphous material continues to surface
    accumulate and layered by amorphous material descending from the metal bath and can finally be
    be.
    According to a preferred embodiment of the present invention, the molten material is sucked into the metal bath by the action of a mechanical disintegrator. This means that the mechanical disintegrator, which, as already mentioned, can preferably be designed as a rotor, is preferably designed in such a way that, during operation of the disintegrator, a type of vortex is formed which is directed in the direction of the depth of the metal bath and which is at the open end of the Sucks the immersion tube melt or molten slag hitting the metal bath into the metal bath. In this way, very high shear forces are applied to the melt to be cooled, which leads to an extremely effective comminution of the melt. This promotes rapid cooling, which in turn encourages the formation of an almost completely amorphous structure.
    structure and low density of the product.
    A number of metals are suitable for use as a cooling medium for the melt, wherein generally metals with a low melting point and high boiling point are favorable for: Use in the context of the present invention. A low melting point makes it possible to provide a metal bath which is very cool compared to the melts introduced, and a high boiling point prevents evaporation losses from the metal bath and the associated development of vapors which are harmful to health and the environment. In this aspect, the method according to the present invention is preferably further developed
    det that the metal bath made of tin, preferably with 3 wt .-%
    7733
    0 ° To "" 00 ° ..o ° ... ..o "
    Silver and to a 1 wt .-% 1 with copper, is formed. Tin has a melting point of 231.93 ° C and the boiling point is 2620 ° C, which is why a wide temperature range can be used to cool slag, for example, without the risk of the metal evaporating. The non-metallic melts which are processed into amorphous granules in the context of the present invention are preferably introduced at approximately 1500 ° C. to 1850 ° C., so that a temperature difference of approximately 1200 ° C. is available for the rapid cooling of the melt to amorphous material. If the tin bath is further alloyed with silver and copper, the melting point can even
    can be reduced to up to 219 ° C.
    According to a preferred embodiment of the present invention, the method is further developed in such a way that the metal bath is kept at a temperature below the recrystallization temperature of the molten material, in particular at a temperature of between 300 ° C. and 600 ° C., in which temperature range even when it is introduced irregularly of molten material there is neither a fear of solidification of the metal bath, nor a temperature of the cooling medium tin which is disadvantageously high for sufficient rapid cooling
    Purchase must be made.
    The temperature of the metal bath can only be maintained under certain circumstances by the heat of the molten material introduced. However, in order to adapt the suitability of the method according to the invention for the processing of large quantities of melts, it can be introduced into the metal bath through the molten material
    Heat by means of one flowing through a heat exchanger
    keep doors.
    The coolant is preferably selected from the group consisting of air, inert gas, thermal oil, water and ionic liquids, in particular aqueous solutions of sodium, magnesium and calcium chloride and potassium carbonate. These coolants are suitable for the temperature ranges relevant in the context of the present invention and can be circulated using systems known in the prior art
    can be controlled thermally.
    In this context, it is particularly advantageous if the heat of the coolant is recovered as mechanical and / or electrical energy, in particular in a gas turbine or a pressurized water heat exchanger with combined heat and power. In contrast to the prior art described above, the method according to the invention allows the heat of the molten material, for example the molten sewage sludge slag introduced into the metal bath, to be extracted with the cooling medium and subsequently used. The amounts of heat contained, for example, in blast furnace or sewage sludge
    are significant and are particularly noticeable
    table high level, so that they come in a variety of
    Processes can be used.
    For example, the heat of the coolant can be used to favor chemical reactions, as in another preferred embodiment of the present invention. The heat of the coolant is particularly preferably used for the depolymerization of plastics, in particular polyethylene, polypropylene and polyethylene terephthalate. In this way, monomers and oligomers, in particular unsaturated oligomers, arise from the polymers and in particular from the polymers of the thermoplastics mentioned, which can subsequently be used in synthetic chemistry for the production of new plastics. The method according to the invention can therefore be useful with disposal processes that differ from the steel industry or the cement industry, for example
    be linked wisely in waste disposal.
    To discharge the amorphous material, the method can preferably be further developed in such a way that the amorphous material is applied with the aid of a conveyor selected from the group consisting of conveyor belt and conveyor wheel. With the feed wheel, the material is conveyed from the surface of the metal bath over an edge or from a discharge area of the granulatedundish in which the metal bath is kept, and then usually falls into a container or a pipe not described here.
    line and can be further processed or deposited. According to a preferred embodiment of the present
    Invention is the metal bath with an inert gas, in particular
    nitrogen purged. On the one hand, this leads to the fact that
    A ..o ° 0 ... ..s °
    the metal bath in that the inert gas displaces the atmospheric oxygen from the surface of the metal bath, the durability of the metal bath is extended and, on the other hand, to loosen the amorphous material floating on the surface of the metal bath, so that tin adhering to particles can run off better . In general, special filtration of the amorphous material during or after removal
    be removed from the metal bath.
    According to a preferred embodiment of the present invention, the method is further developed in such a way that the amorphous material, after being applied with at least one liquid, is selected from the group consisting of water, an aqueous sulfuric acid solution, an aqueous lignosulfonate solution and sulfonated aromatics, in particular aniline, pyridine, Naphthalene, anthracene, phenol and / or cresol derivatives is sprayed, in particular up to a temperature of the glazed material of between 120 ° C and 250 ° C, which leads to sulfation reactions known from the prior art and, as mentioned above, impurities can be removed or converted. The slag products formed in particular significantly improve slag cement processing through a massive reduction in mortar water consumption. This leads to an increase in the early strength as well as the frost and thaw resistance of the mortar and concrete types made from it. Mixtures of dilute sulfuric acid and sulfonated aromatics can of course also be used, thus optimally addressing the particular mortar and concrete application. Such cements also have an increased chemical and
    resistance to sulfates.
    In this variant of the present invention, the vapors formed during spraying are preferably condensed and recovered in order to prevent the vapors from escaping into the working environment and / or the atmosphere and
    at the same time to make the process more economical.
    Due to the surface properties of the amorphous material produced in the course of the method according to the invention, there is no tendency for the metal from the metal bath to adhere to the granulated melt. However, should this happen in individual cases due to the shape of the granules, the method according to the invention can advantageously be further developed in such a way that the amorphous material is filtered and / or removed to remove entrained metal.
    is rifuged.
    The device according to the invention for carrying out the method according to the invention comprises a granulated tundish with a preferably annular cross section for receiving a metal bath, a dip tube with an open end in the pelletizing area of the granulated tundish provided for the metal bath and a discharge area for the amorphous material, characterized in that in the area of the open A mechanical disintegrator at the end of the immersion
    pulls rotor, is arranged.
    For the introduction of the melt, it can be provided according to a preferred embodiment of the present invention that the dip tube at its end opposite the open end with a weir tube in a storage tundish for the molten material for formation
    a possibly interrupted annulus

    works. The formation of an annular space along the circumference of a weir tube in a storage tundish for the molten material leads to the fact that when slag melt or a similar melt enters the dip tube through the annular space, the melt is pre-divided in the dip tube, so that the melt is relatively thinner Film enters the metal bath and can therefore be disintegrated particularly easily. The weir tube can be designed to form an annular space of adjustable height, as this corresponds to a preferred development of the present invention, which makes it possible in a simple manner to regulate the flow of the melt through the annular space into the dip tube and to the respective
    adapt to the requirements of the process.
    In order to ensure a particularly thorough disintegration of the melt when it is introduced into the metal bath, the device according to the invention is preferably further developed in such a way that the mechanical disintegrator is formed by a plurality of actuators which can be driven to rotate and by stators which originate from the wall of the granulated and solid state. If the actuators are driven to rotate,
    because they just missed the stators, so in the
    Areas between the actuators and the stators high shear
    forces occur in the metal bath, which lead to a finely divided breakdown of the melt introduced. This in turn leads to a particularly rapid cooling of the melt in the metal bath and thus to a highly amorphous material as the end product.
    According to a preferred embodiment of the present
    The invention provides that the stators and / or the
    Actuators for the discharge of inert gas, preferably nitrogen, in
    ren trained to carry a coolant.
    According to a preferred embodiment of the present invention, the gas space of the Granulatesundish is connected to a line for inert gas, so that the gas space of the Granulatesundish can also be purged selectively with inert gas, preferably nitrogen, if necessary, in order to increase the durability of the
    Extend metal bath.
    According to a preferred embodiment, the amounts of heat introduced via the melt in the continuous and industrial operation of the method according to the invention and of the device according to the invention can be derived by arranging a heat exchanger as a heat sink in or on the wall of the granulated material. The wall of the granulated tundish mentioned here can either be the bottom and / or at least one side wall of the granulated tundish. Alternatively or additionally, the device according to the invention can also be developed in such a way that a heat exchanger is arranged as a heat sink in the granulated and in the volume for the metal bath. In this case, the heat exchanger is immersed directly in the metal bath,
    which on the one hand improves heat transfer from
    24, ° * .. ° * .. ° ..o ° ... 0 ... "
    Metal bath brings to the cooling medium, but on the other hand exposes the heat exchanger to greater wear and tear, so that the two variants of the arrangement of the heat exchanger mentioned are chosen depending on the area of use or also with one another
    can be combined.
    In a particularly preferred manner, a ″ ′ discharge device in the form of a feed wheel is arranged in the discharge area. With the conveyor wheel, the material is conveyed from the surface of the metal bath over an edge or a discharge opening of a granulated tundish in which the metal bath is held and then usually falls into a container or a pipeline (not described in more detail here) and can be further processed or deposited become. The feed wheel can also be designed as a hollow roller with a perforated surface, on which tin which may still adhere to the granules can run off from the metal bath, as corresponds to a preferred embodiment of the present invention. The separation of adhering tin from the granules can preferably be supported by a nitrogen stream, which is directed from a corresponding register onto the perforated surface of the hollow roller. In addition, the granules can be drawn from the inside of the hollow roller by means of an air or nitrogen stream at a discharge end of the hollow
    roller is blown off the surface of the hollow roller.
    The invention is explained in more detail below with reference to an embodiment shown in the drawing. In

    Carrying device in the form of a hollow roller.
    A device or granulating device 1 according to the invention for use in carrying out the method according to the invention comprises, according to FIG. 1, a granulating tundish 2 in which a metal bath 3 made of liquid tin is kept. From a storage table 4, in which the molten material 5 to be glazed or the melt 5 is located, the molten material 5 is made by means of a weir pipe 6, which together with the storage table 4 forms an annular space 6 ', via the open end 4' ' of the dip tube 4 'in the underlying granulated tundish 2 with the metal bath 3. The melt 5 strikes the surface 7 of the metal bath 3 as an essentially hollow cylindrical jacket and becomes in the metal bath 3 due to the action of the mechanical disintegrator 8, in this case rotor 8, which is driven by the shaft 9 for rotation in the direction of arrow 10 exposed to high shear forces. This leads to a disintegration of the melt 5 in the metal bath, which is cooled in fine particles in the metal bath 3 and instantaneously solidifies in the glassy, amorphous state and is thus granulated. The granulate 11 or the amorphous material 11 is conveyed with the aid of the conveyor wheel 12,
    which is driven to rotate in the direction of arrow 13
    is discharged in the discharge area 14 of the granulated sheet 2 and dropped into a container (not shown). The granulated tundish 2 has a mixing chamber 15 in the area of the mechanical disintegrator 8 or rotor 8, which is kept as constant as possible at a temperature of, for example, 300 ° C. by a heat exchanger 16. The melt 5 flows into the mixing chamber 15 and is mixed into the metal bath 3 there. The bottom of the mixing chamber has an opening 17 through which tin melt is sucked out of the metal bath 3 by the action of the rotor 8, which in the region of the rotor 8 increases the turbulence
    leads to optimize the disintegration of the melt 5.
    18 with a heat exchanger in the volume for the metal bath 3 in the granulated sheet 2 is referred to, in which a coolant 19 flows and via which the majority of the heat introduced by the melt 5 is transported away from the metal bath 3 or from the granulating device 1 and supplied for recycling . The gas space 23 of the Granulatesundish 2 is with
    a cover 22 covered.
    2, the same features are provided with the same reference numerals. In particular, a granulated tundish 2 with a tin metal bath 3 is again shown. About the annulus 6 ’, the height h; can be adjusted by lifting and lowering the weir tube 6 in the sense of the double arrow 6 ’’, the melt 5 can be introduced into the metal bath 3 ’via the open end 4’ ’of the immersion tube 4’ and disintegrated with the aid of the rotor 8. The melt 5 is cooled in fine particles in the metal bath 3 and immediately solidifies in the glassy, amorphous state and is thus granulated. The granulate 11 is discharged in the discharge area 14 and in a
    NEN container not shown. The metal bath
    3 is also held here at a temperature of approximately 300 ° C., which temperature is maintained by means of the heat exchanger 18. The granulated tundish 2 is covered by the storage tundish 4 and the gas space 23 above the metal bath 3 can preferably be treated with an inert gas to protect and thus extend the durability of the metal bath 3.
    gas, especially with nitrogen.
    In the example shown in FIG. 2, the heat exchanger 18 conveys air as coolant 19, the heat of the coolant being recovered as electrical energy via a cogeneration in the form of a gas turbine 24, which is coupled to a generator 25. A fuel can preferably be added to the hot exhaust air or the coolant in a combustion chamber 26 in order, for example, to usefully dispose of low-quality fuels which are produced in the form of dusts, for example in small quantities in the production of the molten material from sewage sludge. 2, the height of the metal bath 3 is to be understood as a granulation zone 27, which is followed by a filtration zone 28 in the gas space 23, in the area of the layered amorphous material 11 or granulate 11, in which
    trailed tin can drip off.
    In FIGS. 3 and 4, the mechanical disintegrator 8 is formed by a plurality of actuators 29 which can be driven to rotate by means of a shaft 9 and stators 30 originating from the wall 2 ′ of the granulated and 2. The actuators 29 and / or the stators 30 can be designed to emit inert gas into the metal bath 3. As can be seen in FIG. 3, there is only a relatively small distance h between the actuators 29 and the stators 30, which means that
    which via the open end 4 ’’ of the dip tube 4 ’into the measuring
    Tallbad 3 introduced melt 5 is exposed to high shear forces for disintegration when the stators 30 are swept by the actuators 29, as shown in Figure 4
    is shown schematically.
    In FIG. 5, instead of a conveyor wheel, a hollow roller 31, which can be driven for rotation in the direction of arrow 31 ′, is arranged in the discharge region 14 and has a perforated surface 32 in order to allow tin, which may adhere to the granules 11, to run off after it has been removed from the hollow roller 31 in Has been detected in the direction of arrow 33 and while the granules 11 are being conveyed to a discharge end 34 of the hollow roller 31 in order to be blown off the surface 32 by a blower 35. In addition to this, a scraper 36 can also be provided in order to scrape granules 11 off the surface 32 of the hollow roller 31. 37 is a register from which a gas stream in the sense of the arrow family 38, in particular from air or an inert gas, in particular nitrogen at 250 ° C., is directed onto the perforated surface 32 of the hollow roller 31 to separate adhering tin from the granulate 11.
