- 摘要:
- 为提高储油罐和输油管道清洗除锈的效率和安全性,探索空化水射流应用的新方式,设计了4种不同的淹没空化水射流喷嘴。采用冲蚀试件的方法,对4种淹没空化水射流喷嘴的冲蚀性能进行了实验,并与角形喷嘴进行比较,重点对内喷嘴入口压力和靶距两个关键因素进行了对比分析。研究结果表明:射流自喷嘴喷出后成白雾状,且伴随着刺耳的噪音,噪音表示空泡破裂的声音;提高内喷嘴入口压力可以有效提高喷嘴的冲蚀能力,由于空化效应的存在,4种淹没空化水射流喷嘴的冲蚀能力均强于角形喷嘴的冲蚀能力;在相同条件下,淹没空化水射流喷嘴外喷嘴收缩段流线型结构优于锥形结构,锥形结构优于圆柱形结构;靶距过大和过小都会影响射流的冲蚀能力,最优靶距与喷嘴的结构有关,所设计的淹没空化水射流喷嘴的最优靶距在30~40 mm之间。该实验研究对储油罐和输油管线清洗除锈具有借鉴意义。
In order to explore the new method of cavitation water jet applied to the cleaning and rusting of oil storage tank and oil pipeline and improve the efficiency and safety of cleaning and rusting，four different submerged cavitation water jet nozzles were designed. Based on the method of erosion test, the erosion performance of four submerged cavitation water jet nozzles was experimentally compared with the angle nozzle. The key factors of inlet pressure and target distance were compared and analyzed. The results show that the jet is sprayed from the nozzle into a white mist, and with the harsh noise. The noise indicates the sound of the cavitation burst; increasing the inlet pressure of the nozzle can effectively improve the erosion ability of the nozzle. The erosion ability of the four submerged cavitation jet nozzles is stronger than that of the angle nozzle due to the cavitation effect; under the same conditions, the streamlined structure of the nozzle in the submerged jet nozzle is better than the tapered structure, and the tapered structure is superior to the cylindrical structure; the optimal target distance is related to the structure of the nozzle. The optimal target distance of the submerged cavitation water jet nozzle is between 30mm and 40mm. The test provides reference for the cleaning and rusting of tanks and oil pipelines.
