摘要:
夹套结构是硫磺喷枪中常用的保温结构,是液硫正常输送和喷射的重要保障.以整个枪体长度上温度分布均匀为目标,对硫磺喷枪夹套进行了结构优化和传热模拟.在常用的蒸汽同侧进出单层夹套结构基础上,对两侧进出单层夹套、同侧进出双层夹套三种结构进行了对比模拟分析.进口以饱和蒸汽和液硫质量流量为基准,出口采用压力出口.选用k-omega湍流模型并开启能量方程,采用压力-速度耦合方程求解,并选用PISO算法.模拟结果表明,两侧进出单层夹套的保温均匀性明显优越于同侧进出单层夹套,而同侧进出双层夹套既有良好的保温均匀性,又能满足蒸汽同侧进出的工艺要求,是一种优化的喷枪传热结构.
Abstract:
Jacketed structure is a thermal insulation structure, commonly used in the sulfur spray gun, which guarantees the normal transmission and injection of liquid sulfur. Aimed at the uniform temperature distribution on the whole length of the gun, the heat transfer simulation and structure optimization of the jacketed structure were explored. Jacketed structure of double-jacket with steam in and out from the same side and single-jacket with steam in and out from both sides were analyzed and compared with that of the commonly used single-jacket with steam in and out from the same side. In the analysis process, the mass flux of saturated vapor and liquid sulfur was used as the benchmark in the inlet, and the outlet adopt pressure-outlet. k-omega turbulence model was used to open the energy equation, and the pressure-velocity coupling equation was solved by using PISO algorithm. The simulation result shows that the thermal uniformity of the single-jacketed structure with steam in and out from both sides is significantly better than that with steam from the same side. However, the double-jacketed structure with steam from the same side is a kind of optimized structure, which not only has a better thermal uniformity, but also meets the technological requirement of steam in and out from the same side simultaneously.
