Abstract

TITRE : DISPOSITIF ET PROCÉDÉ SÉCURISÉ DE TRAITEMENT ÉLECTROCATALYTIQUE DES EAUX L’invention concerne un dispositif (100, 200) électrocatalytique sécurisé de traitement de l’eau, qui comporte : au moins une cellule électrocatalytique comportant au moins une anode (120) et une cathode (115) plongées dans un réservoir contenant du liquide électrolytique, au moins une source de tension électrique configurée pour fournir une tension électrique entre la cathode et l’anode et générer des radicaux hydroxyles sur la surface d’anode par oxydation électrocatalytique de l’eau et au moins un accumulateur et/ou un condensateur raccordé électriquement à l’anode, en vue de prévenir l’apparition de gaz explosifs à la cathode, notamment en vue de prévenir la génération de dihydrogène. L’invention concerne également un procédé électrocatalytique sécurisé de traitement de l’eau. Figure pour l'abrégé : figure 2TITLE: SAFE ELECTROCATALYTIC WATER TREATMENT DEVICE AND METHOD (115) immersed in a tank containing electrolytic liquid, at least one electrical voltage source configured to supply an electrical voltage between the cathode and the anode and to generate hydroxyl radicals on the anode surface by electrocatalytic oxidation of water and at least one accumulator and/or one capacitor electrically connected to the anode, with a view to preventing the appearance of explosive gases at the cathode, in particular with a view to preventing the generation of dihydrogen. The invention also relates to a safe electrocatalytic method for treating water. Figure for the abstract: Figure 2
