The invention relates to a deep desulfurization and dust removal system of a circulating fluidized bed boiler. The system comprises a cyclone and confluence coupled desulfurization technology-based turbulator apparatus arranged in an absorption tower, a spraying apparatus and a pipe bundle type dust removal apparatus, wherein the turbulator apparatus comprises a support part, a plurality of cyclone and confluence apparatuses and a turbulator support beam; each cyclone and confluence apparatus comprises a turbulator floater and a turbulator barrel body; a plurality of pressure blocks for preventing the turbulator floaters from floating up are arranged at the periphery of the support part; upper seal plates are arranged at the upper ends of the turbulator barrel bodies; and after the turbulator barrel bodies and the turbulator floaters are mounted in place, outer rings of the upper seal plates are welded integrally with the pressure blocks. When the turbulator barrel bodies in which the turbulator floaters are
