摘要

近年来，风电累计装机容量的快速扩增带动了风电运维市场需求持续攀升，风电齿轮油是运维中不可或缺的重要组成部分。因废风电齿轮油含有重金属、降解添加剂等有害成分，被归类为危险废物，其高效资源化与无害化处理对实现风电行业清洁化发展至关重要。首先，基于风电齿轮油的特性与组成，阐述了其在运行过程中因外来污染、高温高压氧化及添加剂降解等原因导致的运动黏度、倾点、水分、颗粒污染度、酸值及元素（Fe、P、S等）等典型性能指标变化规律和原因；系统梳理了当前废矿物油再生工艺的最新研究进展，涵盖预处理及分子蒸馏、溶剂萃取、加氢精制等主流技术路线，并分析了上述方法在延长废风电齿轮油寿命及回收再生上的可行性及局限性，如处理效率低、深度不足以及规模化应用受限等问题；最后，从产业层面、技术层面、全链条管理方面探讨了以合成型风电齿轮油为代表的高价值废油未来的发展方向，强调构建分级分类回收体系、开发绿色高效再生工艺与全生命周期管理将是实现风电行业循环经济的关键路径。

Abstract

The rapid expansion of the cumulative installed capacity of wind power in recent years has driven the continuous growth of market demand for wind power operation and maintenance(O&M). Lubricating oil for wind turbine gearboxes is an indispensable and crucial component in O&M. The waste lubricating oil for wind turbine gearboxes is classified as hazardous waste due to its harmful components such as heavy metals and degraded additives. Its efficient recycling and harmless treatment are crucial for achieving clean development in the wind power industry. Firstly

based on the characteristics and composition of waste lubricating oil

the variation laws and underlying causes of typical performance indicators during operating are expounded

including kinematic viscosity

pour point

moisture content

particle contamination level

acid value

and elements(e.g. Fe

and S). These variations are primarily induced by factors such as external contamination

oxidation at high temperatures and pressures

and additive degradation. On this basis

the latest research progress in current waste mineral oil regeneration processes is systematically summarized

covering mainstream technical routes such as pretreatment

molecular distillation

solvent extraction

and hydrofining. Furthermore

the feasibility and limitations of the aforementioned methods in extending the service life of waste lubricating oil and realizing its recovery and regeneration are analyzed. The identified limitations include issues such as low treatment efficiency

insufficient processing depth

and restricted application. Finally

the future development directions of high-value waste oils represented by synthetic lubricating oil for wind turbine gearboxes are discussed from the perspectives of industrial development

technological advancement and life management. It emphasizes that establishing a classified recycling system

developing green and efficient regeneration processes

and implementing life management will be the key pathways to realizing a circular economy in the wind power industry.
