Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization, in particular to an iron-based desulfurizer regeneration device. Background Art

[0002] Hydrogen sulfide is widely present in many industrial raw gas or exhaust gas such as natural gas, coke oven gas, liquefied petroleum gas and biogas. During the storage and transportation of raw gas, hydrogen sulfide will corrode the transmission pipeline and equipment. In industrial production, a small amount of hydrogen sulfide is enough to poison the catalyst, and its oxidation product sulfur dioxide will cause serious air pollution when discharged into the atmosphere, affecting human health.

[0003] At present, there are two main methods for removing hydrogen sulfide: dry method and wet method. Among them, iron-based desulfurizer is a commonly used desulfurizer in the dry method. It has the advantages of wide source, large sulfur capacity, and easy regeneration. It is a classic and effective room temperature desulfurizer; however, the current desulfurizer recovery device cannot separate the used solid desulfurizer, resulting in a waste of resources.
