Background
Although wind power generation is clean energy, a wind turbine generator generates a large amount of wind turbine blade waste to be treated in the production process, the use stage and after the service life of the wind turbine generator is finished. The design life of the wind power blade is 20 years, and the currently domestic wind power blade in actual production and active service is estimated to be retired and scrapped 15 years later or even earlier. According to the measurement and calculation of the installed capacity of the wind turbine generator, about 66 ten thousand tons of retired blades exist in 2025 years, and the quantity of newly added retired blades is about 150 ten thousand tons in 2031 years. Because the wind power blade is made of corrosion-resistant thermosetting composite materials and contains a large amount of organic resin, the wind power blade waste is difficult to naturally degrade, and the wind power blade has extremely strong pollution, can cause long-term harmful influence on the environment by being directly buried or stacked, can not be rotten for a hundred years, can precipitate toxic substances, and can further pollute soil, underground water systems and the like. If directly incinerated, a large amount of heat, toxic gases and smoke are emitted. Therefore, if the treatment is carried out by a conventional mode (random stacking, direct landfill, simple incineration and the like), not only can the treatment be impossible or difficult to be completely carried out, but also the great environmental pollution and resource waste can be caused again, and the strategy is contrary to the resource-saving and environment-friendly sustainable development strategy in China.
From the world, no mature, economic and environment-friendly retired wind power blade recycling treatment application technology exists, the treatment modes of various countries are simple, incomplete and not environment-friendly at present, for example, european and American countries mostly adopt centralized stacking and wait for advanced and economic treatment modes to perform treatment; the small part is disposed by chemical recovery, physical recovery and energy recovery. After the scrapped products of the domestic fan production and manufacturing base or the decommissioned wind turbine generator of the wind farm are disassembled, scrapped glass fiber blades are stacked on the open ground, each blade is cut into a plurality of sections, and the treatment mode is only that the blades are locally stacked and buried. Partial resource utilization technology is lack of product quality standard, sale is limited, the service life of the product is difficult to estimate and is not a final way, and waste still exists and finally returns to a disposal path.
For example, chinese patent publication No. CN109291321A, published as 2019, no. 02, no. 01, discloses a recycling process and apparatus for decommissioned wind power blades, which is only a process for crushing the decommissioned blades and does not provide any subsequent scheme for harmlessness or recycling of the crushed blades.

The device comprises a furnace body, wherein a cooling pipe is arranged outside the furnace body, the top of the furnace body is provided with an opening, the upper end of the furnace body is provided with a smoke outlet communicated with the outside, and the bottom of the furnace body is provided with an ash discharge groove furnace; the furnace body is internally provided with a working cavity, and the furnace body is also internally provided with an electric control feeding door, a spiral stirrer, a gas cloth feeder and an isolation cover, wherein the electric control feeding door and the spiral stirrer are respectively driven by a motor; the electric control feeding door is arranged between the drying area and the pyrolysis area, and a plurality of through holes are formed in the electric control feeding door; the spiral stirrer is positioned in the pyrolysis zone and the combustion zone; the gas distributor is arranged at the bottom of the combustion area, is connected with the spiral bearing and can rotate in the furnace body; the isolation cover is arranged on the inner side of the gas cloth feeder and used for isolating the gas cloth feeder from wind power blade materials. In this scheme, the stove type mainly adopts the fixed bed type, though can handle wind-powered electricity generation blade waste material, but the feeding is intermittent type nature feeding, handles the blade waste material and need smash the material into powdery granule, can not retrieve long glass fibre, can not realize the resource recovery. In addition, due to the presence of resin in the vane components, the powdery material is prone to fouling and clogging in the feed ports and the furnace.
Therefore, the scheme can not realize the aims of recycling, reducing and harmlessness of the retired wind power blade. In order to better treat the waste of the retired wind power blades, a pyrolysis gasification furnace device for continuously treating the waste wind power blades is necessary to be designed, and large-scale industrial application is realized.
