Description

Technical Field

[0001] The utility model relates to the technical field of limestone powder drying, in particular to a limestone powder rapid drying device for desulfurization. Background Art

[0002] Limestone desulfurization refers to the process of using limestone slurry to absorb sulfur dioxide in flue gas in an absorption tower to obtain a mixture of calcium sulfite and calcium sulfate, which is then sent to an oxidation tower and oxidized by air. The resulting calcium sulfate slurry is centrifugally filtered and washed to obtain finished calcium sulfate. When drying limestone powder, a drying device is required;

[0003] However, the existing drying devices usually pour the raw materials of limestone powder into the drying box through the feed port, and use a hot air blower to blow hot air into the interior of the drying box. The raw materials are fully in contact with the hot air, and the moisture is quickly evaporated, thereby completing the drying work. When the feed amount is too large, the raw materials are densely packed together, which easily makes the hot air fluidity poor, prolongs the drying time, and thus reduces the drying efficiency, causing trouble to the staff. For this reason, we propose a rapid drying device for limestone powder for desulfurization. Utility Model Content
