Clean sulfur recovery device

The utility model relates to the technical field of chemical production, in particular to a clean sulfur recovery device which comprises a base. A combustion reaction box, a conversion box, a recoverer, a collection box, a quench tower and an air suction pump are fixedly connected to the upper end of the base from left to right, the lower end of the combustion reaction box is communicated with theconversion box through a first pipeline, the conversion box is communicated with the lower end of the recoverer through a second pipeline, and the upper end of the recoverer is communicated with thelower end of the quench tower through a third pipeline. The lower end of the recoverer is communicated with a collecting box through a fourth pipeline, a fifth pipeline is arranged at the upper end ofthe collecting box, the upper end of the fifth pipeline is communicated with a third pipeline, the upper end of the quench tower is communicated with an air inlet of the getter pump through a sixth pipeline, the upper end of t
