Method and system for efficient pyrolysis recovery and resource cyclic utilization of retired wind power blades
The invention discloses a method and system for efficient pyrolysis recovery and resource cyclic utilization of an ex-service wind power blade, and the method comprises the following steps: cutting the ex-service wind power blade, and carrying out primary pyrolysis at 400-600 DEG C to obtain a primary pyrolysis blade with a locally carbonized resin matrix; carrying out microwave enhanced pyrolysis on the primary pyrolysis blade, and inducing to generate local high temperature and targeted energy to enhance the deposition effect of carbon dots on fibers by utilizing the strong wave absorbing characteristic of carbon-based components in the primary pyrolysis blade, so as to synthesize a fiber-carbon dot composite material in situ; a solid product obtained through microwave enhanced pyrolysis is screened, and a fiber-carbon dot composite material and a carbon black material are separated out; the fiber-carbon dot composite material is used for preparing concrete. According to the method, rapid and efficient dissociation of the resin and the fiber in the retired wind power blade is realized, the treatment time is shortened, and the pyrolysis energy consumption is greatly reduced.
本发明公开了一种退役风电叶片高效热解回收及资源循环利用的方法及系统，包括：将退役风电叶片进行切割后，置于400‑600℃下进行初级热解，得到树脂基质局部炭化的初级热解叶片；对初级热解叶片进行微波强化热解，利用初级热解叶片中炭基成分的强吸波特性，诱导产生局域高温，靶向用能强化炭点在纤维上的沉积作用，以原位合成纤维‑炭点复合材料；对微波强化热解得到的固体产物进行筛分，分离出纤维‑炭点复合材料和炭黑材料；所述纤维‑炭点复合材料用于制备混凝土。本发明实现了退役风电叶片中树脂与纤维的快速高效解离、处理时间缩短及热解能耗大幅降低。
