空化射流清洗技术通过控制压力、流速等参数使水流束经过空化喷嘴时产生大量的空化泡,空化泡在材料表面狭小区域内溃灭产生高达140～170MPa的微射流冲击,实现对水下设施的清洗。在清洗机理、保护防腐层、效率和耗能4个方面分析了空化射流清洗技术相对于高压水清洗技术的优势:高效、安全、节能、不破坏防腐层。采用空化射流清洗技术成功地对印度尼西亚某海底采油井的采油树接口适配器、液压阀、导向盘等设施进行清洗。该技术在海洋石油结构物、海底石油设施、船舶、海岸工程的清洗行业中,具有广阔的应用前景和发展空间。
Cavitation jet cleaning technology through the control of pressure, flow and other parameters so that the flow of water through the cavitation nozzle when a large number of cavitation bubbles, cavitation bubbles collapse in the narrow area of the material surface to produce up to 140 ~ 170MPa micro-jet impact to achieve Underwater facilities cleaning. The advantages of cavitation jet cleaning technology relative to high pressure water cleaning technology are analyzed in terms of cleaning mechanism, protection of coating, efficiency and energy consumption. It is efficient, safe, energy saving and does not destroy the coating. Using cavitation jet cleaning technology, we succeeded in cleaning the tree adapter, hydraulic valve, steering wheel and other facilities in a subsea production well in Indonesia. This technology has broad application prospect and development space in offshore oil structures, offshore oil facilities, ships and offshore engineering cleaning industries.
