This utility model belongs to the technical field of sulfur-containing tail gas treatment equipment, specifically relating to a sulfur-containing tail gas treatment device for carbon nanotube production. The device includes at least three treatment units, each comprising: a tank for storing an alkaline solution and an L-shaped pipe mounted on the tank; wherein the L-shaped pipe penetrates the tank, with its inlet located outside the tank and its outlet located inside the tank and immersed in the alkaline solution; and a pipe connecting the tank in the current treatment unit to the inlet of the L-shaped pipe in the next treatment unit. This sulfur-containing tail gas treatment device for carbon nanotube production introduces the sulfur-containing tail gas into the first tank through the first L-shaped pipe and discharges it from the outlet of the L-shaped pipe.
