(FR) PROCEDE ET DISPOSITIF POUR LA PRODUCTION DE CONSTITUANTS MINERAUX ACCUMULATEURS EN VUE DE L'IMMOBILISATION DE SUBSTANCES NOCIVES, ET POUR LA FABRICATION D'ELEMENTS DE CONSTRUCTION, NOTAMMENT DE PANNEAUX MURAUX, AINSI QUE DE MELANGES
Abstract:
(DE) Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von Speichermineralkomponenten für die Immobilisierung von Schadstoffen und zur Herstellung von Bauteilen, insbesondere von Bauplatten und Gemischen. Die Herstellung der Speichermineralien wird dadurch erreicht, daß Verbrennungsrückstände mit wasserhaltigen Substanzen und CaO vermischt und solange in einem Reaktor aufgeheizt werden, bis das abgegebene Wasser mit dem freien CaO und den Aluminaten sowie Silikaten zur Bildung von hydraulisch aktiven und schadstoffspeichernden Phasen reagiert. Eine erfindungsgemäße Vorrichtung dient zur Umsetzung des Herstellungsverfahrens. Der Einsatz der Speichermineralien zur Herstellung von Bauteilen, insbesondere von Bauplatten und Gemischen wird ebenfalls beschrieben.
(EN) The invention relates to a method and device for producing storage mineral constituents to immobilize harmful substances and to produce building components, specially building slabs and mixtures. The storage minerals are obtained by mixing combustion residues with substances containing water and CaO and by heating them in a reactor until the water thus released reacts with the free CaO and the aluminates and silicates to form hydraulically active phases which store harmful substances. An inventive device is used to implement the above production method. The use of said minerals for the production of building components, specially building slabs and mixtures is also described.
(FR) L'invention concerne un procédé et un dispositif pour la production de constituants minéraux accumulateurs en vue de l'immobilisation de substances nocives, et pour la fabrication d'éléments de construction, notamment de panneaux muraux, ainsi que de mélanges. On produit ces minéraux accumulateurs en mélangeant des résidus de combustion avec des substances aqueuses et du CaO et en les chauffant dans un réacteur jusqu'à ce que l'eau libérée réagisse avec le CaO libre et les aluminates ainsi que les silicates pour former des phases hydrauliquement actives et emmagasinant des substances nocives. Un dispositif selon l'invention permet de réaliser le procédé précité. L'utilisation de minéraux accumulateurs pour la fabrication d'éléments de construction, notamment de panneaux muraux, ainsi que de mélanges, est également décrite.
