Title (EN) FURNACE PLANT AND PROCESS FOR TREATING FURNACE GAS
(FR) INSTALLATION DE FOUR ET PROCESSUS DE TRAITEMENT DE GAZ DE FOUR
Abstract:
(EN) Process and furnace plant for production of liquid metal. The furnace comprises an apparatus (1) for treatment of furnace gas. The apparatus comprises a wet scrubber, preferably a venturi scrubber (6), such as an air gap scrubber, with an outlet connected to a mist eliminator (7) comprising a non-swirling separating device (30, 36), for example a Sulzer Mellachevron™ and optionally a second non-swirling separating device comprising a knitmesh combined with a second Sulzer Mellachevron™. Optionally, the demister (7) may comprise an inlet diffuser, such as a vane-type inlet device, in particular a Shell Schoepentoeter™ (22).
(FR) L'invention concerne un processus et une installation de four pour la production de métal liquide. Le four comprend un appareil (1) destiné au traitement du gaz de four. Ledit appareil comprend un épurateur par voie humide, de préférence un épurateur de type Venturi (6), tel qu'un épurateur à lame d'air, avec un orifice de sortie raccordé à un dévésiculeur (7) comprenant un dispositif de séparation non tourbillonnant (30, 36), par exemple un Sulzer Mellachevron™, et facultativement un deuxième dispositif de séparation non tourbillonnant comprenant un maillage tricoté combiné à un deuxième Sulzer Mellachevron™. Facultativement, le dévésiculeur (7) peut comprendre un diffuseur d'entrée, tel qu'un dispositif d'entrée du type à aubes, en particulier un Shell Schoepentoeter™ (22).
