Embodiment 1

[0057] To transfer the scrapped wind power blades to the designated location, first use mechanical cutting to separate the metal parts and parts with high chlorine content from the main body of the blade. The metal parts are collected and sold in a centralized manner, and the parts with high chlorine content are temporarily stored. After the alternative fuel is blended, it enters the cement kiln under the premise that the chlorine content of the alternative fuel is less than 0.025%.

[0058] After removing the metal parts and parts with high chlorine content, cut the wind power blades into blocks with a length×width of 300×100mm, store the pure glass fiber reinforced plastic parts and the sandwich structural parts with core material, and put the glass fiber reinforced plastic parts and core materials to be pulverized The sandwich structure part is transported to the pulverizer device manually or by conveyor belt, and the pure FRP parts are pulverized by the pulverizer for secon...

Abstract

The invention provides a method for absorbing wind turbine blade wastes in a cement kiln. The method comprises the following steps: separating metal parts and high-chlorine content parts in the wind turbine blade wastes, and segmenting the remaining wind turbine blade wastes as massive wastes; grinding the massive wastes into particles so as to obtain ground materials; and taking the ground materials as alternative fuel of the cement kiln, and combusting the fuel in a cement kiln decomposing furnace. The method disclosed by the invention is simple, practical, less in initial investment and subsequent maintenance cost, environment-friendly and harmless, belongs to a circular economy manner, accords with the treatment policy of 'reduction, recycling and harmlessness' of municipal wastes, can thoroughly implement and carry out the national policy of cooperatively treating non-medical wastes and industrial wastes in the cement kiln, solves the thermosetting material waste disposal difficulty problem troubling the society for a long time, provides alternative fuel and raw materials for the high-energy-consumption cement industry and has wide application prospects.

Description

technical field [0001] The invention relates to the field of wind power blade waste treatment, in particular to a method for accommodating wind power blade waste in a cement kiln. Background technique [0002] Thermosetting materials can be divided into thermosetting resin composite materials and thermosetting plastics. Thermosetting composite materials are generally composed of thermosetting resin as a matrix, glass fiber, carbon fiber and synthetic fiber as reinforcing materials, and wind turbine blades are thermosetting resin composite materials. Due to the excellent properties of light weight, high strength and corrosion resistance, thermosetting composite materials have been widely used in various industries in society. However, during the curing process of thermosetting resins, chemical bonds are formed between molecular chains, and a three-dimensional network structure is formed after curing, resulting in thermosetting materials. Infusible and insoluble, making this t...
