AI Technical Summary
In existing sulfur recovery devices, the reaction between hydrogen sulfide and sulfur dioxide in the combustion gas is insufficient, requiring multiple reactions and affecting sulfur recovery efficiency.
A sulfur recovery device for petroleum refining was designed, which includes a burner and a reactor, combined with a catalytic tube. The mixing of gas and catalyst is regulated by a turntable and an angle plate, and the mixing intensity is controlled by a mixing plate and a screw to increase the reaction efficiency.
It improves the reaction efficiency and speed between hydrogen sulfide and sulfur dioxide, thereby enhancing the efficiency of sulfur recovery.
