摘　　要：对某一特定工艺的小型超临界喷射反应器喷嘴工业化设计进行了分析和探讨。为保证3股流体在指定反应器400〜500℃温度场内充分接触,并力求反应产物生成量最大化,利用有限元仿真方法进行了4种类型喷嘴的喷嘴位置和喷嘴形状工程设计,得到了4种类型喷嘴在反应器内流体的速度场和温度场分布云图。仿真结果表明,喷射反应器喷嘴的位置和形状与流体反应场的大小和稳定性密切相关。可为类似超临界反应器的研发及工程设计提供借鉴。The engineering design process of a nozzle for the supercritical fluid injection reaction based on the specific processing was discussed. The four kinds of nozzles design focusing on its location and shape, in order to ensure the perfect mixing of the three reaction feedings under the condition that the thermal field at the range of 400 ℃ through 500 ℃ was conducted. The maximum reaction production was studied by means of thermal simulation with the finite element method. These results provide a certain reference for the subsequent engineering design and the research, development of similar supercritical reactors.
