Description
Technical field：
The present invention relates to a kind of wet desulphurization reactor, more particularly to a kind of cluster type gas lift desulfurization reactor, belong to chemical work
Journey equipment technical field.
Background technology：
Complex iron is to utilize Fe in the liquid phase3+The oxidisability of L is directly by H in acid gas2S is converted into simple substance S, collects desulfurization and sulphur
It is recovered in one.Simple with flow, desulfuration efficiency is high, the advantages of process economicses are reasonable, is widely used in natural gas, oil
The fields such as work.Due to no Equilibrium limit, H2S removal efficiencies are up to 99.9%, the Bick when latent sulfur content is less than 30 ton day
Louth technique is more economically economical, and have the advantages that equipment be simple and convenient to operate, floor space it is small, be particularly well-suited to medium and small
The desulfurization application of the latent sulfur content of type.
The key reaction of Complexing Iron desulfurization can be divided into absorbing reaction and regenerative response.
Absorbing reaction：
Regenerative response：
Traditional desulfurization gas lift reactor is generally the built-in inner cylinder of the outer barrel of inner/outer drum structure, i.e., and inner cylinder is generally suction
Area is received, outer barrel is zoneofoxidation with the annular space of inner cylinder composition.Generally the empty tower gas velocity of the empty tower gas velocity more than inner cylinder of control outer barrel, makes
The gas holdup of outer barrel thereby results in the apparent density of the apparent density less than inner cylinder of outer barrel, due to close higher than the gas holdup of inner cylinder
The presence of difference is spent, inside and outside cylinder liquid will form automatic cycle.It is passed through the H in inner cylinder2S is by Fe3+L is oxidized to elemental sulfur and is sink to instead
Device tapering is answered, while Fe3+L is reduced to Fe2+L, Fe2+L regenerates as solution is recycled to zoneofoxidation with air contact.
Although traditional desulfurization gas lift reactor has simple structure, easy to operate advantage, this structure also has
Some significant shortcomings.
Uptake zone area is determined by acid gas amount, and zoneofoxidation area is then by acid gas amount and its contained H2S concentration is determined.
It is larger for acid gas amount, and H2S concentration is again relatively low（Volume fraction<1%）Acid gas for, required uptake zone area be much larger than oxygen
Change area's area, to such a operating mode, either inner cylinder or annular space can all cause fluid circulation uneven as uptake zone, shape
The problems such as into circulation dead band.If artificially expanding zoneofoxidation area, air excess can be caused, produce side reaction in system
Thing --- thiosulfuric acid salt content increases, in turn result in proportioning it is liquid-tight degree rise it is too fast, cause tail gas exceeded.
And when the latent sulfur content for processing acid gas is higher, the size of required reactor is larger, and simple inner/outer drum structure is same
Sample can cause serious fluid inequality problem, and accessory substance thiosulfuric acid salt content is raised, and influences reaction efficiency.
The content of the invention：
