Description

Technical Field

[0001] The invention relates to the technical field of cooling devices, in particular to a cooling device for producing steel desulfurizing agents. Background Art

[0002] The Chinese patent with publication number CN211864971U proposes a cooling device for the production of desulfurizers. The patent purges the desulfurizer particles through the air holes on the baffle. The heat on the desulfurizer particles can be taken away during the purging process, and the hot air is finally discharged to the outside from the air outlet pipe at the top of the cooling chamber. However, in this scheme, after the desulfurizer enters the interior of the cooling chamber, it will move out of the downward flowing state, and the temperature of the desulfurizer just produced is relatively high. After the desulfurizer briefly contacts the cooling water pipe, it will directly flow out of the cooling chamber. The desulfurizer stays in the cooling chamber for a short time. When the desulfurizer flows out of the cooling chamber, there will still be residual temperature on the surface, which will lead to poor cooling effect of the desulfurizer. Summary of the invention
