| 摘 要： | 在双喷嘴矩形喷动床内,以空气为喷动气体,研究了最小喷动速度的变化规律和影响因素。实验表明,双喷嘴矩形喷动床的最小喷动速度与颗粒粒径、床层高度及操作温度有关。并在综合考虑床层高度以及气体和固体颗粒的物性的基础上,得出了双喷嘴矩形喷动床最小喷动时雷诺数的经验关联式。

| Abstract: | The change laws and influential factors of the minimum spouting velocity of a rectangular spouted bed with double nozzles were studied with air as spouting medium. The experiment shows that the minimum spouting velocity was related to the particle sizes, bed height, and operational temperatures. Based on a comprehensive consideration of the bed height, and physical properties of air and solid particles, the experiential formula of Reynolds of the rectangular spouted bed with double nozzles at the minimum spouting velocity was derived. |
