Sulfur-containing gas recycling method and sulfur-containing gas recycling system

The invention relates to recycling of sulfur-containing gas, and discloses a sulfur-containing gas recycling method which comprises the following steps: S01, desulfurization: inputting pressurized industrial gas into an absorption device (3) so as to generate a rotating turbulent flow field in the absorption device (3); inputting the pressurized absorbent into the absorption device (3) so as to generate a jet flow field in the absorption device (3); the rotary turbulent flow field and the jet flow field interfere with each other, so that the absorbent absorbs the sulfur-containing gas in the industrial gas; and S02, recycling and regenerating: enabling the absorbent absorbing the sulfur-containing gas to flow out of the absorption device (3), conveying the absorbent into a regenerating device (4) for desorption, discharging the desorbed sulfur gas from the top end of the regenerating device (4), recovering the desorbed sulfur gas, and recycling the desorbed absorbent. In addition, the invention also relates t
