The invention discloses a desulfurizing device for disulfide-containing waste gas. The device comprises a water scrubbing tower and a desulfurizing tower, wherein the outer side of the water scrubbing tower is provided with a feeding pipe; a water scrubbing gas distributor is arranged at the inlet of the feeding pipe in the water scrubbing tower; a discharging pipe is arranged at the top end of the water scrubbing tower; the lower part of the outer side of the desulfurizing tower is connected with the discharging pipe; a desulfurized gas distributor is arranged in the desulfurizing tower; a demister is arranged on the upper part of the desulfurizing tower; a silk screen filling section is formed on the middle part of the desulfurizing tower; a waste gas discharging pipe is arranged at the top end of the desulfurizing tower; and an oil feeding pipe is arranged above the demister. The desulfurizing device has the beneficial effects that the gas distributor is adopted, so that an alkali liquor entrained in waste gas is removed completely, and the content of disulfide contained in the waste gas is lowered to 200mg/m<3> simultaneously by adsorbing and desulfurizing with oil; meanwhile, the silk screen filing section is adopted on the middle part of an adsorbing and desulfurizing tank, so that the content of disulfide in the waste gas can be further lowered to the maximum extent, treated waste gas can be exhausted directly into the atmospheric air though a chimney of 15 meters, and the produced sulfur-containing oil can be conveyed to hydrogenation treatment.
