Description

Technical Field

[0001] The present invention relates to the field of environmental protection equipment and recycling technology, and in particular to an intelligent environmental protection cutting system and method for retired wind turbine blades. Background Art

[0002] Due to environmental factors such as wind, rain erosion and sunlight, the blades of wind turbines are forced to retire after a certain period of use. As a result of technological progress and the expansion of single wind turbines, more and more wind turbine blades are facing the problem of post-retirement disposal and reuse. After the wind turbine is retired, most of the components of the unit are basically recyclable, including the foundation, tower, gearbox and generator. Wind turbine blades are mainly made of glass fiber or carbon fiber, epoxy resin, balsa wood, etc. At present, they are usually disposed of by landfill or incineration in my country, which will cause great harm to human life and the environment.

[0003] At present, there are few publicly published technical studies on the treatment of retired wind turbine blades, and they are mainly based on practical application technologies. The treatment methods for retired wind turbine blades include incineration, pyrolysis, cracking, directional depolymerization, crushing and cutting for reuse. The incineration method has low calorific value, incomplete combustion, easy coking and harmful gas generation; pyrolysis and cracking methods have high energy consumption, many impurities in the product, and are not easy to purify; directional depolymerization technology is not yet mature, the cost is high, the waste liquid is difficult to handle, purification is difficult, and the product added value is low; the crushing method generally crushes the wind turbine blades and then burns them or uses them as additives for building cement, asphalt and other materials, and the economic benefits are not high; the cutting and reuse method has high requirements for cutting tools and special equipment, and must have a stable downstream market. Overall, chemical treatment methods such as incineration, pyrolysis, and directional depolymerization still have many technical difficulties that are difficult to break through, and the conditions for value-added utilization are not yet in place; the physical processing methods of crushing and cutting are more feasible and have less secondary pollution.

[0004] At the same time, due to the large size of the blades and the complex environment after unloading, they cannot be transported to the factory for unified cutting or crushing. Therefore, they need to be disassembled in the field and then transported to the factory for unified cutting. At present, field cutting mainly relies on manual on-site cutting, which is inefficient. In addition, the operating environment of manual cutting of blades is harsh and dust pollution is serious. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent environmentally friendly cutting system and method for retired wind turbine blades, which can realize automated dust-free processing, facilitate dust collection and disposal, and have no wastewater and dust.

[0010] Furthermore, the towing system includes a bracket and a winch for stably supporting and transporting the retired blades.

[0011] Furthermore, the automatic cutting device comprises a multi-sensor cutting head and a multi-axis robotic arm, and the multi-sensor cutting head is used for accurately cutting composite materials.
