Abstract

The invention discloses a circulating fluidized bed boiler system for incinerating waste blades and a working method thereof, and belongs to the technical field of fluidized bed boilers. A secondary air port of a circulating fluidized bed boiler is connected with a secondary fan through a secondary air pipeline; a crushing device is connected with an iron removing device, the iron removing deviceis connected with a conveying device, the conveying device is connected with a crushing device, the crushing device is connected with the secondary air pipeline through a conveying pipeline, and a first induced draft fan is arranged on the conveying pipeline; a flue gas outlet of the circulating fluidized bed boiler is connected with an inlet of a cyclone separator through a horizontal flue, and an upper end outlet of the cyclone separator is connected with a flue gas tail gas treatment system; and a bottom outlet of the cyclone separator is connected with a material returning system through avertical pipe, and the material returning system is connected with a material returning inlet of the circulating fluidized bed boiler. The system is reasonable in structure, the change of an originalCFB boiler system is small, the heat value of the waste blades is fully utilized, and centralized, harmless and resource treatment of the waste blades is realized.

Description

technical field [0001] The invention belongs to the technical field of fluidized bed boilers, and in particular relates to a circulating fluidized bed boiler system for incinerating waste blades and a working method thereof. Background technique [0002] In recent years, the wind power industry has maintained the characteristics of sustained and rapid development. From another perspective, the comprehensive disposal of waste blades deserves attention. Since the service life of wind turbines is mostly 20 years, from this year onwards, wind turbines that gradually reach the warranty period will inevitably be eliminated or undergo transformations to improve quality and efficiency (such as blade replacement, etc.), followed by a large number of eliminated blades , plus the broken blades that appear during the operation of the fan, as well as the production scraps of the blade enterprises (such as release cloth, guide net and vacuum film, etc.), together constitute the waste bla...
