Definitions
- the invention relates to a method for producing a mineral melt for the production of mineral fibers, in particular rock wool for thermal and / or acoustic insulation and for fire protection, substrates for plant breeding, reinforcing fibers and fibers for filtration purposes, in which at least from Production-derived residues as well as correction materials for setting the required composition and viscosity of the melt are crushed and pressed with a binder to form stones and the stones are fed to a melting unit.
- Stone wool insulation materials are used for heat, sound and / or fire protection. Stone wool products are also used to breed plants or to strengthen e.g. Coating materials or other products or also used as fibers for filtration purposes. In the following, the rock wool products listed as examples are collectively referred to as mineral fiber products.
- glass wool is commonly distinguished from rock wool.
- Stone wool is mainly produced from mixtures of broken effusion stones, such as basalt or diabase, and small amounts of limestone, dolomite and magnesite as supplements, as well as from broken effusion stones and coarse blast furnace slags and, if necessary, additional small quantities of limestone, dolomite and magnesite.
- These supplements can be added to the batches individually or in different mixtures with one another.
- the broken raw materials are increasingly being replaced by artificially manufactured bodies of the appropriate size, shape and strength, which are composed of various raw and residual materials as well as suitable binders. These bodies are referred to below as shaped stones.
- the shaped stones can contain fine-grained, broken natural stones.
- Production-related residues are added as additional components, for example the coarser constituents that inevitably arise during the manufacturing process, such as melting pearls, the solidified melt resulting from the regular emptying of the melting furnaces together with the partially melted rock remnants and parts of the furnace lining made of refractory building materials as well as the insulation materials or substrates. that occur when trimming an endlessly produced fiber web.
- Other production-related residues are leftovers, defective products or used insulation materials or substrates to be melted.
- the production-related residues are prepared for the production of shaped blocks, ie crushed, ground and then mixed with correction substances. With the help of these correction substances, the required composition of the batch is achieved, which causes a uniform and rapid melting in the melting unit. At the same time, the temperature and viscosity of the resulting melt are influenced to such an extent that the most efficient, evenly running defibration process is achieved.
- Correction materials are, for example, slags from the steel industry such as converter or ladle slags or melting chamber granules from coal-fired power plants. Substances containing aluminum in oxidic and / or metallic form are also considered to be essential correction substances here. Suitable carriers are raw bauxite or calcined bauxite, as well as alumina cement, which of course can also function as a binder.
- DE 101 02 615 A1 discloses the use in this regard of catalysts which are no longer usable from the petroleum industry.
- Correction substances which contain both Al 2 O 3 and metallic aluminum are the slags described in WO 99/28252 A1 which occur when aluminum is recovered from Al scrap. These slags also contain small amounts of Na sulfates and Na fluorides.
- correction substances are ores, such as hematite (Fe 2 O 3 ) or magnetite (Fe 3 O 4 ).
- the granular and fibrous components, the internal residues and the correction substances are predominantly mixed with inorganic binders, mostly with the addition of water, and then pressed into shaped bodies.
- inorganic binders are to be understood to mean hydraulically setting cements such as standardized Portland cements, but also all types of special cements, as well as the alumina melt cements already mentioned.
- the proportions of the binders in the shaped blocks are approximately 9 to 15% by mass.
- the conveying and loading in general the shape stones reach a minimum compressive strength of approx. 3-5 MPa after 3 days, for example, they are added to the melting unit together with the other raw materials or alone, but always together with the lumpy fuels required for the melting process. This is where the melt required for fiber formation is produced, which is then fed to the defibration unit.
- the defibration unit usually consists of several rollers rotating at high rotational speeds and staggered one above the other.
- the temperature and the viscosity of the mineral melt have a considerable influence on the processability on the respective defibration unit.
- the optimal processing range of the melt can therefore be specifically influenced by the choice of raw materials.
- the chemical composition of the melt and the mineral fibers made from it affect their biosolubility, i.e. the dwell time in the human organism. Biosolubility results to a decisive degree from the proportions of the oxides and compounds of silicon, aluminum, titanium, sodium, magnesium, potassium, calcium, iron and their relationships to one another. For example, the levels of boron oxides are also important for bio-solubility.
- a typical composition of a mineral melt for the production of commercially available, bio-soluble rock wool essentially consists of the following:
- the invention is based on the task of developing a generic method for producing a mineral melt for the production of rockwool in such a way that, on the one hand, the costs for the raw materials are reduced, but at the same time the properties of the mineral fiber products to be produced be improved if possible.
- the solution to this problem provides that constituents of the shaped blocks, in particular the correction substances and / or other batch constituents, are at least partially replaced by granular combustion residues, in particular ash or slag, from the combustion of preferably lignite and / or hard coal dust, paper sludge or wood chips ,
- the correction substances mixed with the residues originating from the production for the production of the shaped blocks are partially substituted by combustion residues.
- compositions of the ashes and slags usually vary within certain limits.
- waste materials are burned in a fluidized bed at a temperature> 800 ° C.
- Fuels are mixed in for the combustion of low calorific value waste materials.
- the fluidized bed is created by adding fluidizing air through a nozzle bottom.
- Fuel and / or the waste materials can be conveyed from above onto the fluidized bed by means of throwing feeders or also directly into the fluidized bed by means of screw conveyors.
- the degassing and gasification of the fuel and the burning of the solid carbon take place in the fluidized bed.
- Volatile components can be re-burned or the heat can be recovered using heat exchangers.
- the process-related intensive mixing and combustion, the good heat transfer in the fluidized bed, as well as the residence time of the hot flue gases leave with regard to the moisture and chemical, mineralogical and granulometric composition of fluidized bed ash, which are highly uniform.
- Such filter ash can now not only substitute a part of the correction substances in the production of molded blocks because of their chemical composition, but surprisingly also influence the development of strength of the molded blocks in a very favorable manner. This effect is due on the one hand to the latent hydraulic properties of some of the ashes mentioned, and / or to the reaction-accelerating effect on the binders used, and ultimately also to their particle sizes.
- both the early strength and the final strength surprisingly increase. The final strength has no practical meaning here.
- the CaO content in such ashes can be increased to 70% and the SO 3 content to 20%. This reduces the percentage of the other components accordingly.
- the strength requirements can be reduced, which is usually done by reducing the proportion of binder. Saving potentials of, for example, approximately 5 to approximately 15 mass% of the binder contents normally used are possible.
- the combustion residues described above in particular ashes and / or slags, preferably filter ashes, have chemical compositions which are particularly suitable for correcting the compositions of mineral melts for the production of mineral fibers.
- the combustion residues reduce the viscosity of the mineral melt at the usual processing temperatures. This makes it possible, for example, to produce evenly finer mineral fibers, which in turn have a favorable influence on the performance properties of the mineral fibers and the mineral fiber products made from them. At the same time, such a melt has a material-saving effect on the defibration unit.
- the relatively high proportion of Al 2 O 3 in some of the combustion residues enables the substitution of other alumina carriers.
- the aluminum oxide itself promotes the bio-solubility of the mineral fibers.
- ashes from the combustion of lignite and hard coal dust as well as paper sludge and wood chips have proven to be particularly suitable.
- the method according to the invention also has the advantage that the combustion residues that are otherwise to be disposed of in the landfill can now be recycled.
- the ingredients of the combustion residues have a glass-forming effect, otherwise they change glass. It is very important that actually undesirable components of the combustion residues are incorporated into the glasses in a poorly soluble form through the controlled manufacturing process.
- this form of recycling also significantly reduces the burden on the environment. This applies even if the mineral fibers are not recycled again after the end of their use phase, but are instead disposed of.
- combustion residues in particular filter ash from, for example, fluidized bed combustion processes, which result from the combustion of lignite and hard coal dust, paper sludge or wood chips, have advantageous properties with regard to the strength formation of the shaped stones due to their high fineness and their chemical composition for the production of shaped stones , At the same time, they have a positive effect on the melting behavior of these shaped stones when producing a mineral melt and offer the possibility of a targeted viscosity Control of the mineral melt. Finally, these combustion residues make a positive contribution to improving the biosolubility of the mineral fiber products made from these mineral melts.
- shaped stones are pressed which are made from 38 to 64% by mass of production-related residues, 5 to 20% by mass of melting chamber granulate, 0 to 11% by weight of converter slag, 0 to 14% by weight of ladle slag as correction substances , 10 to 25% by mass of Al 2 O 3 carriers, for example bauxite, 9 to 12% by mass of cements and 1 to 5% by mass of ashes from the combustion of paper sludge.
- the proportion of converter slag and ladle slag as well as cement is reduced in comparison to a corresponding composition of shaped blocks according to the prior art. Accordingly, in this exemplary embodiment there is a substantial reduction in the proportion of cement, which results in a substantial reduction in the production costs of the shaped blocks.
- the correction substances are contained in the composition of the shaped blocks as follows:
- another exemplary embodiment provides that production-related residues in a proportion of 38 to 64% by mass with a proportion of melting chamber granules of 0 to 15% by mass, converter slag 0 to 15% by mass and ladle slag 0 to 18% by mass % as correction substances and an Al 2 0 3 carrier, for example bauxite, in a proportion of 5 to 20 mass% together with 1 1 to 13 mass% cements and a proportion of 5 to 25 mass% ash from the Braun - / Coal combustion can be mixed.
- an Al 2 0 3 carrier for example bauxite
- the correction substances are at least partially substituted by granular combustion residues, namely ashes from the brown / hard coal combustion, the sewage sludge combustion, the wood combustion or from the paper production. This results in a reduction in the cement requirement, namely the cost-intensive binder, and improved viscosity control.
