This invention discloses a dust removal device, a hot dirty gas deacidification and dust removal system, and a method based on a granular bed. Existing granular bed filters suffer from defects such as numerous dead zones in filter media replacement. The dust removal device of this invention includes a coarse filter tower, a fine filter tower, a filter media tower, a filter cartridge, and a filter media recovery unit. The dust removal system includes a granular bed-based dust removal device, a dust separation device, a filter media silo, and an ejector. In this invention, the filter media tower, fine filter tower, and coarse filter tower are embedded and coaxially arranged, forming an inlet chamber for hot dirty gas and an outlet chamber for hot clean gas. A filter cartridge with an upper cone is concentrically arranged inside the fine filter tower, and the filter cartridge is constructed with a Johnson mesh to form a diffusion chamber. The central filter media is diverted through the filter cartridge to increase its travel, and undergoes two stages of filtration with the hot dirty gas through cross-flow and counter-flow, greatly increasing the dust holding capacity of the central filter media. Furthermore, the entire filter bed moves smoothly downwards, effectively solving the problem of easy fluidization of the bed material in counter-flow granular beds and improving the deacidification and dust removal efficiency.
