The existence form of sulfur in blast furnace gas is complex, mainly comprising organic sulfur COS and inorganic sulfur H 2 S, and therefore, the emphasis of blast furnace gas desulfurization is the removal of COS. The current technical route generally converts organic sulfur into inorganic sulfur H which is easy to remove 2 S, then considering the removal of H according to the load, the sulfur content and the like 2 And S. The hydrolysis conversion method needs medium-temperature hydrolysis conditions, the temperature is 100-200 ℃, and organic sulfur COS is converted into H under the action of a catalyst 2 S。
The hydrolysis tower reactor is generally an axial flow or radial flow reactor, and the radial flow reactor has the obvious characteristics of large flow passage sectional area, small flow velocity, small bed resistance and the like relative to the axial flow reactor, so that the hydrolysis tower is more suitable for adopting the structure.
For example, CN112195043A discloses a blast furnace gas desulfurization device, which is characterized in that blast furnace gas subjected to fine dust removal by a bag-type dust remover is fed into a hydrolysis catalytic tower for hydrolysis catalytic desulfurization, and the blast furnace gas is subjected to hydrolysis catalyst action in the hydrolysis catalytic tower, wherein COS in the blast furnace gas is converted into H 2 And S. However, it provides only one method, and the device is very general, and has no internal specific structure.
CN111500325A discloses a live blast furnace gas organic sulfur hydrolysis device, which is characterized in that a hydrolysis catalyst is placed on the upper part of an internal support beam, at least one layer of catalyst is placed in a reactor, the placement intervals of the catalysts in each layer are equal, the structure is simpler, the device is a typical axial flow reactor, but the system resistance is larger.
