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 system for extracting glass fiber and pyrolysis oil from fan blades of the present invention mainly consists of 4 parts:

[0038] The first part is a conventional CFB boiler, including the furnace 1, the horizontal flue 2, the first cyclone separator 3, the tail flue 4, the economizer 5, the air preheater 6 and the figure 1 Other equipment and installations of CFB boilers not shown in , such as primary air / secondary air system, heating surface, dust collector and chimney, etc. These devices constitute a complete CFB boiler system, which can generate high-temperature and high-pressure steam for steam turbine power generation. As a conventional coal-fired power generation device, the operation of the blade pyrolysis recovery system ...

Abstract

The invention discloses a system and working method for extracting glass fiber and pyrolysis oil from fan blades, belonging to the technical field of resource recovery. Including crushing system, circulating fluidized bed boiler system, fluidized bed pyrolysis furnace, non-contact heat exchanger, pyrolysis gas-solid separation system and cracking oil separation system. The system can effectively crack composite materials in waste blades and recover glass fiber and pyrolysis oil. The cracked gas is pumped to the furnace for effective incineration, and the calorific value contained in it is effectively utilized. The pollutants generated by combustion rely on the environmental protection device equipped with the original boiler system It can achieve emission standards, and the pyrolysis reaction in the anoxic atmosphere in the fluidized bed pyrolysis furnace effectively avoids the potential generation and emission of dioxins caused by the direct incineration of waste blades, and realizes the harmlessness and recycling of waste fan blades deal with. Before the comprehensive recycling technology of blade materials is mature and used on a large scale, it can effectively solve the impact of waste blades on the environment and produce good environmental protection and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of resource recovery, and in particular relates to a system for extracting glass fiber and pyrolysis oil from fan blades and a working method thereof. Background technique [0002] The wind power industry has entered a period of rapid development for nearly 20 years, and the annual newly installed capacity has continued to increase. On the other hand, due to reasons such as design life, a large number of wind turbines are facing elimination every year, and blade damage and damage caused by abnormal operation of wind turbines The leftover waste and defective products of blade enterprises together constitute a large number of discarded / waste blades (collectively referred to as waste blades) that need to be disposed of comprehensively every year. Effective recycling of waste leaves can meet the expectations of building an environment-friendly society, and the harmless resource disposal of waste leaves is worthy...
