Large wind power generation blade recovery treatment method and treatment system

Abstract

The invention relates to a large wind power generation blade recovery treatment method and a treatment system for recycling large-size damaged blades. The treatment method comprises the following steps: (1) large-size damaged blades to be recovered are cut into small-size blade blocks; (2) the blade blocks are shredded as powder; (3) the powder is separated as resin glass fiber powder and light material powder according to material types; (4) the resin glass fiber powder is activated by using an activating agent, and is dried to obtain activated resin glass fiber powder; and (5) the activatedresin glass fiber powder, resins, short glass fibers, an initiator, a demolding agent and fillers are uniformly mixed to obtain agglomerated mixtures for producing material products so as to achieve recycling of the large-size damaged blades. Compared with the prior art, the treatment method is low in cost and stable and reliable in operation, prevents the material waste, improves the material utilization rate, and achieves a wide application range of the agglomerated mixtures.

Description

technical field [0001] The invention relates to the technical field of wind power blades, in particular to a method and system for recycling and processing large wind power blades. Background technique [0002] Wind power blades are mainly made of thermosetting materials and fiber materials. Generally, large wind power blades have a blade length of more than 40m and a maximum width of more than 2m, which is huge. When wind power blades reach the end of their service life, they need to be processed. At present, there is no mature processing method, and they are all cut into relatively small blade pieces by manual cutting (but still relatively large, with a maximum size of no more than two meters. ) for reuse or disposal. In practice, the disposal method is usually adopted, and the secondary utilization is limited, resulting in waste of materials and low utilization rate of materials. Contents of the invention [0003] The object of the present invention is to provide a la...
