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 for extracting glass fiber and pyrolysis oil from a fan blade and a working method thereof, and belongs to the technical field of resource recovery. The system for extracting the glass fiber and the pyrolysis oil from the fan blade comprises a crushing system, a circulating fluidized bed boiler system, a fluidized bed pyrolyzing furnace, a non-contact heat exchanger, a pyrolysis gas-solid separation system and a pyrolysis oil separation system. According to the system, the composite materials in the waste blades can be effectively pyrolyzed, the glass fiber and the pyrolysis oil can be recycled, the pyrolysis gas is pumped to a hearth to be effectively incinerated, the contained heat value is effectively utilized, and pollutants generated by combustion can be discharged in a standard reaching mode by means of an environmental protection device arranged in an original boiler system; and a pyrolysis reaction in the fluidized bed pyrolyzing furnace under the oxygen deficit atmosphere effectively avoids the potential problems of dioxin generation and emission and the like caused by direct incineration of the waste blades, and harmless and resourceful treatment of the waste fan blades is achieved. Before the comprehensive recycling technology of the blade material is mature and is utilized on a large scale, the system for extracting the glass fiber and the pyrolysis oil from the fan blade can effectively solve the influence of the waste blades on the environment, and generate 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...
