- 摘要:
为实现储罐清洗工作的安全与环保,有必要将空化水射流清洗技术引入到储罐清洗中。对一种带有扩散角的中心体喷嘴进行研究,利用Fluent计算软件对不同扩散角的中心体喷嘴诱发空化射流的情况进行数值模拟,分析其压力、轴向速度和气相体积分数。模拟结果表明:在 15 MPa 的压力入口下含有扩散角的中心体喷嘴诱发空化的效果,明显优于不含扩散角的中心体喷嘴;同时中心体喷嘴因扩散角不同,其空化产生的效果也不同,扩散角为15°时中心体喷嘴诱发空化的效果最好。因此合理地选择中心体喷嘴的结构参数,可以更好提高储罐清洗的质量。
In order to achieve the safety and environmental protection of the tank cleaning, the cavitation water jet cleaning technology is introduced into the tank cleaning work.A central body nozzle with a diffusion angle is studied.The Fluent calculation software is used to simulate the cavitation jet induced by the central body nozzles with different diffusion angles,and the pressure, axial velocity and cavitation volume fraction are analyzed.The simulation results show that the effect of cavitation induced by the central body nozzle containing the diffusion angle under the pressure inlet of 15 Mpa is significantly better than that of the central body nozzle without the diffusion angle.At the same time, the central body nozzle has different effects due to its different diffusion angles.When the diffusion angle is 15°, the effect of cavitation induced by the central body nozzle is the best.Therefore, a reasonable selection of the structural parameters of the central body nozzle can better improve the quality of the tank cleaning.
