Description
Technical field
The utility model is related to a kind of system of Recovered sulphur, and more specifically, the utility model is related to a kind of Crouse
The system of direct current method Recovered sulphur, belongs to Clausius equlity sulphur technical field.
Background technology
Simultaneously Recovered sulphur is that current utilization rate is most wide to Claus method treatment hydrogen sulfide acid gas, efficiency highest technique, H2S acid
Gas in combustion furnace, by supplementing appropriate air, makes H by after buffering2S burn incompletelys in combustion furnace, H2S portion burns
It is converted into SO2, adjust air inlet amount.H in combustion furnace2S and SO2Ratio is 2:1, H2S and SO2Reaction occurs under ignition temperature
Redox reaction, can obtain gaseous elemental sulphur(Sulphur).Mix waste gas make gaseous elemental sulphur be cooled to liquid through over cure cooler
State sulphur, now acid gas include H2S、SO2、COS、CS2、H2After O and sulphur steam etc., reheated device or high temperature blending valve, acid gas temperature
Temperature needed for claus reaction device is brought up to, then by LT claus reaction device, in the presence of catalyst, COS, CS2Then
With H2There is hydrolysis in O, obtain H2S, H2S and SO2Reaction is further continued for, acid gas further reclaims sulphur through over cure cooler after reaction
Sulphur.Acid gas is by three-level(Two-stage)After reactor, still there is very small amount H in tail gas2S、SO2、COS、CS2、H2O and sulphur steam
Deng reclaiming certain sulphur by catching sulphur device, then by incinerator, fully burn into SO2After discharge.
