Definitions
- Thermal decomposition plant and method Melt. Glazing and for the recovery of valuable materials from various types of waste and residues.
- the invention relates to a plant and a method for thermal decomposition, for melting, vitrification and for recovering valuable materials from various types of waste and residues at high temperatures in a closed reaction chamber with openings for supplying the material to be treated, reactants and removing the gaseous or liquid reaction products
- Waste incineration plants with grate firing, rotary kiln or pyrolysis furnace are also known.
- Melting baths (salts or metals) for the decomposition and ine ⁇ ation of waste are also known others in use are also known as rotating cookers (horizontal, vertical) with various pouring devices. These systems are mostly very well suited for the treatment of one type of waste, such as household waste.
- the object of the invention is to convert a wide variety of wastes into valuable and unproblematic substances by means of a thermal process, so that
- this is done by programmable supply of gases into the melt through vertically and tangentially arranged nozzles or by the action of electromagnetic fields or by a combination of both methods.
- the reaction gases are fed to the aftertreatments known per se by means of an induced draft blower in a predetermined range
- Reactive gases such as oxygen, hydrogen, steam, etc. can be blown directly into the melt through the vertically and tangentially arranged nozzles in order to achieve the desired reactions
- Such wastes can be loaded onto the surface of a melt made of inorganic constituents via a drum charging device, a screw conveyor or other methods of conveying
- a barrel separator eg acetylene burner
- the gripper can be moved axially as well as rotated. This separates the barrel with the barrel separator so that the contents including barrel residues are evenly distributed over the melt
- the bath movement ensures a good distribution of the material. After a certain bath height has been reached, the melt is poured off. The flue gases are completely oxidized in an afterburner chamber. In the subsequent flue gas cleaning, the emissions are reduced below the applicable limit values Flue gas cleaning residues are returned to the reactor after the water has been separated off
- Dust-like residues and waste such as filter dust containing metal
- these residues are introduced under the melt provided (for example pneumatically blown in).
- the reducible metal oxides such as CuO, FeO ZnO, PbO, NiO etc.
- the melt is separated as liquid metal or evaporated with the flue gas. This process is supported by a corresponding combination of electromagnetic movement and fumigation.
- the volatile metals eg Zn
- the two phases, the metallic part and the non-metallic part of the melt, are poured off separately from the melt volume.
- Mixed wastes containing metal e.g. B. used catalysts from chemical industry can be fed into the reactor.
- the organic constituents are decomposed and the recovered metals are enriched in a mother melt.
- the inorganic residues are incorporated into a glassy or crystalline matrix.
- gases can be conveyed directly through the gassing openings into the melt or into the heat source, whereby particularly efficient decomposition can be achieved.
- This system is also particularly suitable for processing radioactive waste into products that can be disposed of.
- melt 8 can be set in motion with the gassing elements 10.
- rotation of the melt can be achieved with the tangentially arranged elements.
- the melt movement is first initiated by periodic gas pulses. As soon as the melt movement has started, it is maintained by continuous gassing. The speed of rotation can be regulated by the amount of gas blown in. The gas flow is regulated via valves which are controlled by a programmable gas controller 14. If there is a corresponding melt, the rotation can optionally be supported by the electromagnetic stirring elements 11. All of these elements are integrated in the lower part 2 of the reactor. As soon as the melt rotates, the actual loading process begins through the loading device. tion 6 The rotation results in an even distribution of the material on the

Abstract
L'invention concerne une installation et un procédé pour la décomposition thermique, la fusion, la vitrification et la récupération de matériaux provenant de déchets et de résidus de natures les plus variées, à haute température, dans une chambre de réaction fermée, munie d'ouvertures pour l'alimentation en produits à traiter et en substances participant à la réaction et pour l'évacuation des produits de réaction gazeux ou liquides. Le matériau à traiter est introduit dans le réacteur par des dispositifs de chargement (6) et traité thermiquement au moyen de brûleurs (3). La matière en fusion peut être agitée au moyen d'éléments de gazéification spéciaux (10). La matière en fusion peut être soumise, en plus d'un brassage au moyen d'éléments de soufflage verticaux, à un mouvement de rotation provoqué par des éléments disposés tangentiellement. Le réglage du courant gazeux s'effectue par l'intermédiaire de vannes commandées par un régulateur de gaz programmable (14). Pour des matières en fusion appropriées, le mouvement de rotation peut être renforcé, si on le désire, par des agitateurs électromagnétiques (11). Ce mouvement de rotation permet d'obtenir une répartition uniforme du matériau dans la masse en fusion, cependant que la gazéification verticale contribue à un brassage intensif de cette masse. Les deux effets accélèrent la formation de surfaces libres et le contact intensif du matériau avec les sources de chaleur riches en énergie, ce qui permet d'obtenir une excellente efficacité réactionnelle. Les gaz de combustion formés sont envoyés, via des moyens d'extraction, dans des dispositifs de traitement ultérieur connus en soi. Le matériau à traiter peut également être introduit sous la surface de la matière en fusion. Dès que le traitement est terminé, le moulage contrôlé est effectué par l'intermédiaire du système de moulage avec le dispositif de fermeture et le dispositif de coulée.
