烧结竖罐床层内的空隙率分布特性
Voidage distribution properties of bed layer in sinter vertical tank
摘要
Abstract
Water flood method and tomographic image analysis method were used to investigate sinter bed layer average voidage and radial voidage distribution. The effect of bed layer geometric factor on bed layer average voidage was studied, and the bed layer radial voidage distribution was also studied under the condition of different bed geometrical factors. The results show that the main factors that influence the bed layer voidage distribution are the sinter particle diameter and bed layer diameter of vertical tank. Among them, the bed layer average voidage decreases with the increase of bed layer geometric factor for a given sinter particle diameter under the condition of smaller bed geometrical factor (D/d p<120). On the contrary, the bed layer average voidage does not vary with the change of particle diameter or bed layer diameter. Bed layer voidage is the largest at the inner wall surface, then decays to the center of bed layer, and finally reaches the minimum value in the center of bed layer.关键词
