Sulfolane distillation tail gas treatment device

The utility model relates to a sulfolane distillation tail gas treatment device. The sulfolane distillation tail gas treatment device comprises a gas-liquid separation tank, a stripping tower, a stripping tower kettle and an air stripping pipeline, wherein the stripping tower is connected with a sulfolane distillation tail gas pipeline, at least one layer of filler is arranged at the middle part of the stripping tower, a spray head is arranged at the upper part of the filler, the spray head is connected with the gas-liquid separation tank through a pipeline, and a total reflux condenser is arranged at the top of the stripping tower; the stripping tower kettle is mounted at the bottom of the stripping tower, and a plurality of gas bubbling devices are arranged in the stripping tower kettle; and the air stripping pipeline is connected with the plurality of gas bubbling devices via the total reflux condenser. The sulfolane distillation tail gas treatment device provided by the utility model can overcome the defects of the prior art, effectively remove sulfur dioxide in sulfolane distilled water steam, and recycle a condensate after stripping, thereby reducing the post-treatment cost and reducing the production of waste liquid.
