Fixed bed desulfurizing agent drying device

The utility model provides a fixed bed desulfurizer drying device. Relates to the field of material drying equipment and comprises a shell, conveying belts, an air supply pipeline and an air return pipeline, a cavity is formed in the shell, the multiple conveying belts are sequentially arranged from top to bottom to form multiple layers, the rotation directions of the adjacent conveying belts are opposite, the tail end of each conveying belt is provided with a guide plate facing the head end of the adjacent lower-layer conveying belt, and the conveying belts penetrate through the cavity. The air supply pipeline and the air return pipeline are communicated with the cavity; in order to solve the problem that an existing material drying machine cannot meet the requirement for the dryness of a desulfurizing agent, a multi-layer conveying belt structure is adopted, conveying belts convey materials to be air-dried in an inner cavity of a shell, in the multi-layer conveying process, the materials fall onto a lower-l
