退役电工装备回收再利用技术挑战与路径规划
Technical Challenges and Path Planning for the Recycling and Reuse of Decommissioned Electrical Equipment
摘要
Abstract
Under the national carbon peaking and carbon neutrality goals and the accelerated green transformation of so-cioeconomic development,advancing research and innovation in ecological cycling and recycling technologies for decommissioned electrical equipment in the energy and power sectors has become a critical initiative for developing a circular economy,promoting sustainable resource utilization,and fostering ecological civilization.Centering on the theme of ecological cycling and recycling of decommissioned electrical equipment,this paper systematically introduces the technical challenges and pathway planning for the recycling of wind turbine blades,solar photovoltaic modules,compo-site insulators,cables,transformer insulation materials,and energy storage lithium battery devices from the aspects of power generation,transmission,substation,and energy storage domains.The study aims to facilitate the establishment of an ecological cycling system for electrical equipment,thereby supporting the construction of China's new power system and advancing high-quality development of the circular economy.Research has shown that efficient recycling of carbon fibers in wind turbine blades requires breaking through the technical bottleneck of selective degradation of epoxy resin and maintaining fiber strength.Although non-destructive recycling of photovoltaic modules can improve the regeneration efficiency of silicon wafers,the EVA film dissociation process needs to balance the toxicity of chemical reagents and high energy consumption during pyrolysis.The recycling of composite insulators needs to take into account the high-value uti-lization of silicone rubber degradation products and equipment corrosion risks.The efficient conversion of cable cross-linked polyethylene insulation materials still needs further exploration.关键词
