Abstract

L'invention concerne un désulfurant de gaz brûlés à colonne liquide, capable de faire face avec souplesse aux variations de conditions telles que les performances de désulfuration, le réglage du champ, etc., permettant de minimiser l'augmentation du coût et du temps de construction. Dans le désulfurant de gaz brûlés à colonne liquide destiné à réaliser une désulfuration en amenant un liquide absorbant, projeté vers le haut à partir d'une buse (20) de colonne liquide et retombant dans une tour de désulfuration, en contact gaz-liquide avec un gaz d'échappement de combustion qui s'élève depuis le bas de la tour de désulfuration, un embout (30) de sortie présentant un débit de jet différent ou une structure de jet différente de liquide absorbant est fixé de façon amovible au bout de la buse (20) de colonne liquide. En fixant un mécanisme de dispersion de la colonne liquide au bout de la buse de colonne liquide, la dispersion d'une colonne liquide peut être accélérée et la surface de liquide absorbant amenée au contact du gaz d'échappement de combustion peut être accrue. Par conséquent, le rendement de désulfuration peut être amélioré et la taille de la tour de désulfuration peut être réduite, ce qui est très efficace pour réduire l'encombrement et le coût d'installation du dispositif.
