Background With the rapid increase of the global wind power installation capacity, the production amount of waste wind power blades is continuously increased. At present, the traditional treatment mode of the waste wind power blades mainly comprises landfill and mechanical crushing, but the inherent defects of the waste wind power blades are increasingly prominent. The landfill treatment not only needs to occupy a large amount of land resources, but also the wind power blade is mostly made of composite materials such as glass fiber reinforced resin, carbon fiber reinforced resin and the like, the chemical property of the materials is stable, the degradation period in the natural environment is hundreds of years, and the long-term environmental hidden dangers such as soil pollution, underground water infiltration pollution and the like are easily caused, meanwhile, the early-stage investment of site selection, seepage prevention treatment and the like of the landfill site is huge, and the wind power blade is limited by land planning, and is difficult to popularize in large scale in densely populated areas. Mechanical crushing can disassemble blades into fine particles, but only can realize 'volume reduction' instead of 'recycling', the added value of the crushed mixture of fiber particles and resin scraps is extremely low, the crushed mixture is mostly used as roadbed filling materials or building aggregate, the resource utilization rate is less than 5%, more importantly, a large amount of superfine fiber dust and volatile organic compounds can be generated in the crushing process, if no effective environmental protection measures are available, dust pollution and respiratory tract health risks are easily caused, and secondary harm is caused to operators and surrounding environments. In order to solve the limitation of the traditional method, the industry tries to treat the waste wind power blades by adopting the conventional pyrolysis technology, but the technical short plates still have difficulty in meeting the dual requirements of recycling and environmental protection. The conventional pyrolysis technology relies on external heat sources such as electric heating, gas heating and the like, has low heat transfer efficiency and uneven temperature distribution of a reaction system, causes incomplete cracking of a resin matrix in the blade composite material, is easy to generate heavy tar and refractory organic residues, reduces the recovery rate of target products such as combustible gas, carbon fiber and the like, and is difficult to meet the requirements of resource utilization and environmental protection emission. Therefore, a technology for treating waste wind power blades with high efficiency, high automation degree and environmental protection is needed.
