Patent

CA 2647205

The invention relates to a method for treating solids-containing process gas (7) in a suspension smelting furnace (1), comprising directing the process gas from the reaction shaft (2) of the suspension smelting furnace to a lower furnace (3) and, further, through a raised shaft (4) to a waste heat boiler (6) to cool the process gas, whereby, through one or more gas nozzles (8) placed on the lower furnace top wall (12), oxidizing gas (9) is fed into the process gas (7) flowing in the lower furnace (3), whereby the amount of oxidizing gas is adjusted during the process so that the amount of sulphides contained in the solid matter of the process gas that is directed to the waste heat boiler (6) is minimized. The invention also relates to the equipment.

La présente invention concerne un procédé pour traiter un gaz de processus (7) contenant des éléments solides, dans un four de fusion de suspension (1). Le procédé consiste à diriger le gaz de processus de la cuve réactionnelle (2) du four de fusion de suspension à un four inférieur (3), puis, via une cuve élevée (4), à une chaudière de récupération de chaleur (6) destinée à refroidir le gaz. Selon l'invention, une ou plusieurs buses (8) placées sur la paroi supérieure (12) du four inférieur, permettent à du gaz d'oxydation (9) d'être introduit dans le gaz de processus (7) qui circule dans le four inférieur (3), la quantité de gaz d'oxydation étant ajustée au cours du processus de sorte que la quantité de sulfures contenus dans la matière solide du gaz de processus qui est dirigé vers la chaudière de récupération de chaleur (6), est minimisée. L'invention se rapporte également à l'équipement pour mettre en oeuvre ce procédé.
