- 将空气雾化和机械雾化相结合，对硫磺喷枪进行改进.在Fluent软件环境下，基于气、液两相流模型进行了计算流体力学数值模拟.进口处以液硫、空气的实际速度为基准，出口处采用压力出口，焚硫炉内壁面选用标准无滑移壁面并假设其绝热，以简化焚硫炉内气液边界条件.以k\|epsilon湍流模型为计算模型，采用压力\|速度耦合方程求解，并选用压力修正算法.结果表明，在喷枪四周输入一定速度的空气后，喷枪附近形成一个涡流负压区，加速液硫向四周扩算，可增大雾化角及雾化行程，均匀雾滴分布.以某焚硫炉的工程实际参数，液硫速度5 m/s时，对比不同空气流速下的液硫雾化流场，在空气进口速度为4～6 m/s，雾化效果最佳.
- Abstract:
- Air atomization and mechanical atomization are combined to improve the performance of the sulfur spray gun. The FLUENT software was used to analyze the field of velocity on the basis of two\|phase\|flow model. The actual speed of liquid sulfur air was selected as the inlet boundary condition while the pressure was chosen as the outlet boundary condition .Standard no\|slip wall was adopted as the wall of sulfur furnace, which was assumed adiabatic to simplify the gas\|liquid boundary conditions of sulfur furnace. The k\|epsilon turbulence model was adopted as the calculation of the model, while the pressure\|velocity coupling equation and the pressure implicit with splitting of operators algorithm were applied to calculation. The results reveal that there is a negative pressure of vortex near the spray gun when a given velocity of air is steady，which accelerates the expansion speed of liquid sulfur，increases the angle and distance of atomization and makes the atomization distribution more homogeneous. Taking the data of a sulfur furnace, it demonstrates that the best atomization result comes up at 4~6 m/s of the inlet velocity when the speed of liquid sulfur is set at 5 m/s.
