[0052] Example one
[0053] Term Interpretation: Complexed iron desulfurizer desulfurization: It is a technique using a complexed iron desulfurizer to accomplish a technique of removal of sulfurized hydrogen sulfur sulfide, and the hydrogen sulfide content is less than 20 mg / m3 in the desulfurization gas. Become a solid sulfur product.
[0054] Such as Figure 1 - Figure 4 As shown, the present application discloses a suitable complex iron desulfurizer desulfurization system, including a desulfurization torch 1, and the dethylsulfur tower 1 is connected to the settling separator, the settling separator is connected to the low-level regenerator 3, low-level regeneration The device 3 is a regenerator liquid phase distributor, the settling separator communicates with the plate frame through the suspension pump, the plate frame is connected to the low-bit regenerator, the plate frame is connected to the preparation, The pre-processor is in communication with the metering commercial s...

[0060] Example 2
[0061] Such as Figure 5 and 6 As shown, the present application also discloses a desulfurization method suitable for complexing iron desulfurizer, including the following steps:
[0062] S1, the sulfide gas-containing gas into the center of the desulfurization column is in contact with the desulfurization column from the top of the desulfurization column, which is detached from the sulfide gas, and the gas is discharged from the top of the desulfurization column into other steps;
[0063] S2, absorbing hydrogen sulfide after hydrogen sulfide is from the lower liquid segment to the settlement separator, the settling separator separates the desulfurization rich liquid from sulfur particles from the low-grade regenerator, the sediment separator separated high-fixing The suspension is filtered through a suspension pump, and the filter filtered filtrate is fed into the low-level regenerator, and the filter cake filtered through the plate frame is flowing into the sul...
