[0003] The SDS dry desulfurization system has the characteristics of small footprint, simple operation and maintenance, and high desulfurization efficiency. At the same time, during the operation of the SDS desulfurization system, since the desulfurization agent used in the SDS sodium-based dry desulfurization is sodium bicarbonate, the products after the desulfurization reaction are mainly sodium sulfate and carbon dioxide. Carbon dioxide is produced while removing sulfur dioxide, which is not conducive to carbon emission reduction;
