Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment, and its content is explanation of the present invention rather than limitation:

[0036] Such as figure 1 , The system for disposing of waste fan blades in the calciner of the present invention relies on the dry cement rotary production process, and the raw materials such as clay and limestone are crushed and transported to the homogenizing bin 1 in a certain proportion for homogenization and mixing treatment to form raw materials. There is a discharge port at the bottom of the homogenizing bin 1, which is transported to the bucket elevator 3 through the first auger 2, and is lifted to a certain height of the suspension preheater 5 by the bucket elevator 3. After the bucket elevator 3 is unloaded, it is also used The second auger 4 transports the raw material and sends it into the suspension preheater 5 . By controlling the speed of the seco...

Abstract

The invention discloses a system for treating waste fan blades in a decomposing furnace and a working method of the system, and belongs to the technical field of resource recovery. The system comprises a blade crushing system, a raw material feeding system, a flue gas treatment system, a suspension preheater, a decomposing furnace, a rotary kiln, a clinker cooling device and a fan coal mill. Crushed waste fan blade particles are merged into a pneumatic conveying pipeline at the downstream of the fan coal mill and are conveyed into the decomposing furnace together for pyrolysis and combustion, heat released by combustion of organic composite materials of the waste blade particles and heat released by combustion of pulverized coal provide energy for dehydration and decomposition of raw materials together, and the potential heat value of fan blades is effectively utilized. Glass fibers in the blade particles, combusted pulverized coal and ash residues formed by combustion of the pulverized coal are mixed into the raw material together, enter a downstream suspension preheater, are finally separated and are returned to the rotary kiln to participate in clinker firing. Harmless and resourceful treatment of the waste fan blades is achieved, and good environmental protection benefits and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of resource recovery, and in particular relates to a system for disposing of waste fan blades in a decomposition furnace and a working method thereof. Background technique [0002] The wind power industry is showing a rapid development trend, and the newly installed capacity is increasing every year. On the other hand, due to the design life and other reasons, a large number of wind turbines are facing elimination every year. The leftover waste and defective products together constitute a large number of discarded / waste blades (collectively referred to as waste blades) that need to be disposed of comprehensively every year. [0003] In terms of material composition, fan blades are mainly composed of composite materials (epoxy resin, etc.), fiber reinforced materials (such as glass fiber, etc.), adhesives (such as epoxy adhesives, polyurethane adhesives, etc.) and coatings. Organic composite materials accoun...
