烧结混合料干燥过程的解析研究
Analysis of Sinter Mixture's Drying process
摘要
Abstract
A one-dimensional and cross flow analytical model for sinter mixture was established, and then the model was verified correctly by tunnel drier experiment. Based on these, the law and influence factors of sinter mixture during drying process were analyzed. The results show that the drying process of the sinter mixture consists of two stages, namely, a short long constant-rate stage, and a long falling-rate stage, furthermore, the drying rate in falling-rate stage is almost linear. The effect of temperature and the flow rate of the hot air to drying process are better than that of porosity and average diameter particles obviously. It is beneficial to appropriate moisture content when temperature and the flow rate of the hot air were 200 ~250℃ and 1. 5 m/s, respectively.关键词
