Description
Technical Field
[0001] The utility model relates to the technical field of wind turbine blade recovery, in particular to a wind turbine blade pyrolysis recovery and utilization device. Background Art
[0002] Wind power has been rapidly developing as a clean energy source. The main material of wind turbine blades is thermosetting composite materials, which are lightweight, high-strength, heat-resistant, corrosion-resistant, and have good design performance. They have always been the blade material of large wind turbines. However, with the development and use of wind power, early batch wind turbines will face the problem of large-scale decommissioning. A large number of scrapped wind turbine blades will become industrial solid waste, polluting the environment and wasting resources.
[0003] The recycling and treatment of discarded wind turbine blades has always been a research hotspot. Currently, there are various methods for processing discarded wind turbine blades, including crushing for construction materials, high-temperature cracking to recover fibers, dissolving (supercritical fluid and solvent) to recover resin and fibers, and cement manufacturing methods. These domestic and foreign technologies all face problems such as high energy consumption, small processing capacity, and the generation of secondary pollution.
[0004] Among them, the use of microwave cracking treatment method to treat discarded wind turbine blades can enhance the purity of fiber recovery. This method requires cutting the discarded wind turbine blades into blocks, crushing the wind turbine blades and then cracking them. Finally, the cracking products are added to a microwave sintering furnace and sintered in an oxygen-containing atmosphere to remove the residual carbon on the surface of the reinforcing fibers to obtain recycled products. However, the existing crushers are often not thorough enough in use, and the crushing process is single, making it impossible to achieve continuous multi-stage crushing treatment. Not only is the crushing effect on block materials unsatisfactory, but the crushing efficiency is also reduced. For this reason, we propose a wind turbine blade pyrolysis recycling device.
