Description

Technical Field

[0001] The utility model relates to the technical field of denitration catalyst processing, in particular to a denitration catalyst drying device. Background Art

[0002] Denitrification catalyst refers to the catalyst used in the SCR denitrification system of power plants. In the SCR reaction, it is a substance that prompts the reducing agent to selectively react chemically with nitrogen oxides in the flue gas at a certain temperature. The denitrification catalyst needs to be fully dried when drying and packaging. The denitrification catalyst production process includes primary drying and secondary drying. However, most of the existing SCR denitrification catalyst drying heat cycle devices need to evenly spread the chemical on the storage plate inside the drying box for drying before drying, which makes it inconvenient to place it on the storage plate close to the inside of the drying box, and loading and unloading are more troublesome. When there are too many catalysts to be dried, they can only be placed in the drying box in a piled form, which will result in poor drying effect.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN216924959U in the prior art discloses an SCR denitration catalyst drying heat circulation device, including a drying box, a heat cycler, a shelf and a storage plate. A shelf is arranged inside the drying box, and sliding bars are welded on the upper and lower surfaces of the shelf. The sliding bars are slidably arranged on the inner wall of the drying box. Several groups of heat cycles are evenly installed on the inner wall of the drying box, and several groups of through holes are evenly opened on the shelf and the storage plate, and driving mechanisms are arranged on both sides of the shelf.

[0004] Although the above-mentioned prior art solution avoids excessive accumulation of the drying catalyst on the storage plate, resulting in poor drying effect, it still requires workers to collect the materials on the storage plate one by one after drying, which is cumbersome and affects work efficiency.
