摘要
首先,介绍国内外风电叶片的使用规模和退役风电叶片趋势,阐述国际上通用的退役风电叶片处置方式(堆放、掩埋、回收利用)及其优缺点;其次,系统介绍废弃叶片材料的典型回收利用方法,即机械回收、热回收和化学回收,比较3种典型回收利用方法的技术特点;然后,总结了利用退役风电叶片进行产品再制造的典型案例,包括制备再生复合材料板材、制造混凝土骨料、制备3D打印耗材等;最后,针对风电材料常见的玻璃纤维复合材料、碳纤维复合材料等的难切削性能,介绍风电叶片回收加工技术与装备,包括切割加工技术和装备、破碎及粉碎加工技术和设备等。
Firstly,the application scale of wind power blades at home and abroad and the trend of decommissioned wind power blades are introduced,and the international common disposal methods of decommissioned wind power blades(stacking,burying,and recycling)and their advantages and disadvantages are described.Secondly,the typical recycling methods of waste blade materials,namely mechanical recycling,thermal recycling,and chemical recycling,are systematically introduced,and the technical characteristics of the above three typical recycling methods are compared.Thirdly,the typical cases of product remanufacturing using retired wind power blades are summarized,including the preparation of recycled composite plates,the manufacture of concrete aggregates,the preparation of 3D printing consumables,etc.Finally,aiming at the difficult cutting performance of common wind power materials such as glass fiber composites and carbon fiber composites,the recycling processing technology and equipment of wind power blades are introduced,including cutting processing technology and equipment,crushing and crushing processing technology and equipment,etc.
