Title (EN) PROCESS FOR COLLECTING SOLID MATERIAL PRESENT IN GAZEOUS,LIQUID OR SOLID WASTE
(FR) PROCEDE DE RECUPERATION DE SUBSTANCES SOLIDES PRESENTES DANS LES GAZ, LES LIQUIDES OU LES DECHETS SOLIDES
Abstract: front page image
(EN)To collect the valuable or dangerous solid material present with a low concentration in exhaust gases or liquid, textile structures are used which are made of easily soluble synthetic materials. The solid components which adhere to the textile structures are collected by dissolving them in a solvent in which these solid elements are soluble; These solid elements are then separated by sedimentation, centrifugation or filtration. To recover uranium or plutonium present in raw solid waste material from plants for processing nuclear fissile materials, these waste material are dissolved (tank 4) after they have been crushed (plant 2). The non-dissolved combustible elements are extracted by centrifugation (centrifugal machine 6). The solvants are evaporated (evaporator 71-73); (81, 82), condensed (condensing unit 9) and brought back into the circuit. The non-soluble remains are dipped into the bath of the melting synthetic material which is then solidified, into storing containers.
(FR)Pour recuperer les substances solides precieuses ou dangereuses presentes a faible concentration dans les gaz d"echappement ou les liquides, on utilise des structures textiles faites de matieres synthetiques facilement solubles. On recupere les elements solides qui adherent aux structures textiles en dissolvant ces dernieres dans un solvant dans lequel ces substances solides ne sont pas solubles; on separe ensuite les substances solides par sedimentation, centrifugation ou filtration. Pour recuperer l"uranium ou le plutonium presents dans les dechets solides bruts issus des usines de traitement des matieres fissiles nucleaires, on dissout ces dechets (cuve 4) apres les avoir concasses (installation 2). Les elements combustibles non-dissous sont extraits par centrifugation (centrifugeuse 6). Les solvants sont evapores (evaporateur 71-73); (81, 82), condenses (condensateur 9) et ramenes dans le circuit. Des residus non-solubles sont noyes dans le bain de matiere synthetique en fusion qui est ensuite solidifie dans des enceintes de stockage.
