Embodiment Construction

[0036] 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:

[0037] Such as figure 1 , the waste fan blade pyrolysis recovery system of the present invention mainly consists of 3 parts:

[0038] The first part is a conventional circulating fluidized bed boiler, including furnace 1, horizontal flue 2, first cyclone separator 3, tail flue 4, economizer 5, air preheater 6, first return feeder 7, The secondary air duct 8 and the figure 1 Other equipment and installations of CFB boilers not shown in , such as primary air system, heating surface, dust collector and chimney, etc. As a conventional coal-fired power generation device, the CFB boiler system can operate normally regardless of whether the fan blade pyrolysis recovery device is operating or not.

[0039] The second part is a crushing and crushing device for waste b...

Abstract

The invention discloses a waste fan blade pyrolysis recovery system and a working method thereof, and belongs to the technical field of resource recovery. The waste fan blade pyrolysis recovery system comprises a crushing system, a circulating fluidized bed boiler system, a pyrolysis reactor, a material collecting and conveying device, a pyrolysis gas-solid separation system and a cracking oil separation system. According to the invention, composite materials in waste blades can be effectively cracked, cracking oil generated by cracking can be recovering, cracking gas is pumped to a hearth to be effectively incinerated, heat value contained in the cracking gas is effectively utilized, pollutants generated in the combustion process can be discharged in a standard reaching mode by means of an environment-friendly device arranged in an original boiler system, and a pyrolysis reaction in a pyrolysis reactor under an anoxic atmosphere effectively avoids the potential problems of dioxin generation and emission, and the like caused by direct incineration of the waste leaves, so that harmless and resourceful treatment of the waste leaves is completely achieved; and before the comprehensive recycling technology of the blade material is mature and utilized on a large scale, the influence of the waste blade on the environment and the like can be effectively solved, and good environmental protection benefits and economic benefits are generated.

Description

technical field [0001] The invention belongs to the technical field of resource recovery, and in particular relates to a waste fan blade pyrolysis recovery system and a working method thereof. Background technique [0002] In recent years, the wind power industry has shown a rapid development trend, and the annual newly installed capacity has been increasing. From another perspective, the comprehensive disposal of waste blades deserves attention. Since the design life of fan blades does not exceed 20 years, early fans will not be decommissioned or undergo blade replacement and other quality and efficiency improvements. Constitute a large number of waste blades (collectively referred to as) that need to be disposed of comprehensively. [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...
