Title (EN) REDUCTION-OXIDATION FURNACE FOR MAKING PHOSPHORUS BY THERMAL PROCESS
(FR) FOUR DE RÉDUCTION-OXYDATION POUR LA FABRICATION DE PHOSPHORE PAR UN PROCÉDÉ THERMIQUE
(ZH) 热法炼磷的还原氧化炉
Abstract: front page image
(EN)A reduction-oxidation furnace (200) for making phosphorus by thermal process comprises a furnace body (50) and a spray gun (21, 26). The furnace body (50) comprises a slag outlet (23, 24), a flue gas outlet (22) and a molten mass inlet (27) through which molten phosphorus ores are added into the furnace body (50). One end of the spray gun (21, 26) is inserted into the furnace body (50). The reduction-oxidation furnace (200) for making phosphorus by thermal process can reduce the impurities in the flue gas with P2O5, which facilitates the extraction of the P2O5 with high purity and low cost.
(FR)L'invention porte sur un four de réduction-oxydation (200) pour la fabrication de phosphore par un procédé thermique comprenant un corps de four (50) et un pistolet de pulvérisation (21, 26). Le corps de four (50) comprend une sortie de laitier (23, 24), une sortie d'effluent gazeux (22) et une entrée de masse fondue (27) par laquelle des minerais de phosphore fondus sont introduits dans le corps de four (50). Une extrémité du pistolet de pulvérisation (21, 26) est introduite dans le corps de four (50). Le four de réduction-oxydation (200) pour la fabrication de phosphore par un procédé thermique permet de réduire les impuretés dans l'effluent gazeux comprenant du P2O5, ce qui facilite l'extraction du P2O5 à une pureté élevée et à un faible coût.
