海上风电设施防腐蚀技术研究进展

Research Progress of Anti-Corrosion Technology for Offshore Wind Power Facilities

海上风电是一种绿色能源,目前受到越来越多的关注,海上风电设施防腐蚀技术已成为当下的研究热点。首先,阐述了海洋环境中设备的腐蚀机理,继而介绍了海上风电设施常用防腐技术,包括防腐涂层、阴极防护、预留腐蚀裕量法等;然后,结合实例,重点介绍了飞溅区新型防腐手段中的热喷涂与矿脂包覆覆层防腐蚀技术;最后,简单分析风电设施防腐检测与检修技术,并介绍了我国已建成并网发电的广东珠海桂山风电项目所用的腐蚀防护手段,以期为提高我国海上风电防腐水平提供参考。

Offshore wind power is a kind of green energy,which has attracted more and more attention.The anti-corrosion technology of offshore wind power facilities has become a current research hotspot.This paper first expounded the corrosion mechanism of equipments in the marine environment,and then introduced the commonly used anti-corrosion technologies for offshore wind power facilities,including the anti-corrosion coatings,cathodic protection,reserved corrosion allowance method,etc.Then,combined with an example,the anti-corrosion technology of thermal spraying and mineral grease coating in the new anticorrosion method in splash area were introduced emphatically.Finally,it briefly described the anti-corrosion detection and maintenance means of wind power facilities.It also introduced the corrosion protection methods used in Guishan wind power project in Zhuhai,Guangdong,which has been built into grid connected power generation in China,in order to provide some suggestions for improving the anti-corrosion level of offshore wind power.
