LOUVER STRUCTURE FOR SUPPORTING GRANULAR SUBSTANCE-PACKED LAYER

PURPOSE:To eliminate accumulation of dust from waste gas at a particle-moving part and to inhibit corrosion of louvers caused by oversaturated adsorption of SO2, by arranging sub-louvers inside conventional louvers so as to eliminate a part, where particles do not fluidize, on the louvers. CONSTITUTION:Two couples of main louvers 6 and sub-louvers 7 are located two-abreast in a fixed distance inside an adsorption column 5, and an adsorbent 8 is filled in a space between the two-line louvers. The inclining direction of the louver elements of the sub-louvers 7 is set in parallel with that of the main louvers 6, the sub-louvers 7 are located at the intermediate positions of the main louvers 6 along their vertical direction, and the size of the sub-louvers 7 is made smaller than that of the main louvers 6. Consequently, particles smoothly fluidize on the main louvers 6, and a particle-unfluidizing area is scarcely formed on even the sub-louvers 7.
