Abstract

Les dispositifs connus d'élimination ne sont pas adaptés à l'élimination de matières toxiques et permettent seulement un fonctionnement discontinu. En outre, le remplacement des pièces d'usure est très coûteux et très complexe. Le dispositif selon l'invention est conçu de sorte qu'au moins la garniture interne de la chambre d'explosion et de combustion (4) est constituée d'anneaux d'acier (5) superposés qui forment, une fois assemblés, une ouverture d'admission supérieure (3) dans la chambre d'explosion et de combustion (4) pour l'introduction de la matière dangereuse et une ouverture d'évacuation inférieure (6) pour les déchets produits. L'ouverture d'admission (3) de la chambre d'explosion et de combustion (4) peut être fermée par un corps d'acier (10) suspendu de façon à pouvoir être descendu dans la chambre de sas (1). Ce dispositif peut être employé entre autres pour l'élimination d'explosifs et de matières toxiques.
