Description
Technical Field

In the complex iron wet desulphurization process, iron ions directly react with hydrogen sulfide, so that the hydrogen sulfide is converted into elemental sulfur and precipitated, the iron ions are converted into ferrous ions, and then the ferrous ions are oxidized into the iron ions through introducing air, thereby completing the regeneration of the desulfurizer. The complex iron wet desulphurization process has the advantages of high sulfur capacity, low investment and operation cost, skid-mounting capability, high sulfur absorption efficiency and green and environment-friendly process. The existing complex iron wet desulphurization process also has certain problems, and aims at the oxidation tower, because the regeneration stage of the complex iron wet desulphurization process is carried out under normal pressure, in order to ensure the activity of the desulfurizer, the gas velocity in the oxidation tower is generally very low so as to meet the regeneration requirement of the desulfurizer, the low gas velocity can cause the deposition speed of sulfur to be accelerated, if too much sulfur in the desulfurizer is carried, the sulfur is likely to be deposited and blocked on the tower wall, the cone bottom and the tower internals of the oxidation tower, and the problem is difficult to be solved by blowing the blowing ring alone.
