摘要
风电机组“退役潮”临近，大量退役风电叶片的无害化处理是风电产业实现完整绿色闭环的重要瓶颈。在国家积极实施煤电节能降碳改造的背景下，燃煤锅炉协同处理退役风电叶片可以实现固废的减量化、资源化、无害化。针对退役风电叶片规模化连续热处理的需求，提出一种燃煤锅炉耦合风电叶片热解气化的工艺路线；通过抽取锅炉烟气作为热解气化的热源，热解气化产生的可燃油气送入炉膛燃烧，简化了风电叶片处理流程，减少了初投资。采用ASPEN Plus软件对该工艺进行了模拟和验证，结果表明：当风电叶片的处理速度为1 t/h时，抽取总烟气的比例不超过0.6%，即可满足热解气化的能量需求；基于7 MW的链条炉进行中试试验研究，发现烟气中含氧量为5%～10%时，可以通过“一步热解气化”得到干净的玻璃纤维；基于模拟结果和试验数据，提出一种带有烟气调质协同处理工艺，即通过掺混省煤器出口烟气、加入空气的方式，控制烟气温度为600～700℃、含氧量为5%～10%，以提高回收纤维的强度，并进一步简化风电叶片处理流程，为风电叶片的规模化处理提供参考。
Abstract
The “retirement wave” of wind turbines is approaching
and the harmless treatment of a large number of decommissioned wind turbine blades is an important bottleneck for the wind power industry to achieve a complete green closed loop. Under the background of the country's active implementation of energy conservation and carbon reduction renovations in coal-fired power plants
the co-processing of decommissioned wind turbine blades by coalfired boilers can achieve the reduction
resource utilization and harmless treatment of solid waste. In response to the demand for large-scale continuous heat treatment of decommissioned wind turbine blades
a process route of coupling coal-fired boilers with pyrolysis-gasification of wind turbine blades is proposed. By extracting the flue gas from the boiler as the heat source for pyrolysis-gasification
the combustible oil and gas produced by pyrolysisgasification are sent into the furnace for combustion
simplifying the processing procedure of wind turbine blades and reducing the initial investment. The process was simulated and verified by using Aspen Plus software. The results indicate that when the processing rate of wind turbine blades was 1 t/h
the proportion of flue gas extracted did not exceed 0.6%
thereby meeting the energy requirements for pyrolysis-gasification. A pilot-scale experimental study was conducted based on a 7 MW chain grate boiler
and it was found that when the oxygen volume fraction in the flue gas was 5%～10%
clean glass fibers could be obtained through “one-step pyrolysis-gasification”. Based on both simulation results and experimental data
a flue gas conditioning-based integrated treatment process was proposed: control the flue gas temperature at 600～700 ℃ and the oxygen volume fraction at 5%～10% by blending flue gas from the economizer outlet and adding air
so as to enhance the strength of the recovered fibers and further simplify the wind turbine blade treatment process
providing a reference for the large-scale treatment of wind turbine blades.
