[0002] The ash conveying device for an SDS desulfurization tower in the flue of a circulating fluidized bed boiler is a device used to treat sulfur dioxide in the flue gas discharged from coal-fired or gas-fired boilers. Fuels such as coal and natural gas will generate pollutants such as sulfur dioxide during the combustion process, and these pollutants need to be treated by desulfurization equipment to comply with environmental protection regulations and reduce air pollution. The SDS desulfurization tower is a common wet desulfurization equipment used for the absorption and conversion of sulfur dioxide in flue gas. At the same time, an ash conveying device is also required to treat the generated waste residues, which are used to treat the ash and waste residues generated during the desulfurization process. These systems can include mechanical ash conveying devices, conveyor belts, pneumatic ash conveying systems, etc., to ensure the safe and efficient transportation of ash and slag to the ash storage bin or waste residue treatment facility.

[0003] However, most of the existing ash conveying devices for desulfurization towers transport the filtered ash through pipelines and screw conveying devices, and it is very likely that the ash will adhere to the inner wall of the pipeline during transportation. Moreover, the internal filter screen is not easy to disassemble and replace when filtering dust. Therefore, an ash conveying device for an SDS desulfurization tower in the flue of a circulating fluidized bed boiler is proposed to address the above deficiencies. Content of the Utility Model
