The operation principle of Novel anti-blockage desulfurizer 100 provided by the utility model is：First, when sulfur-containing gas with
After admission line 1 enters absorption tower 3, hydrogen sulfide and other sulfide are absorbed by the desulfurizing agent in absorption tower 3, by sulfur-containing gas
In hydrogen sulfide remove, natural gas after purification is by knockout drum 2, after removing the moisture in purified gas, into follow-up work
Industry produces or storage；Meanwhile desulfurizing agent rich solution (desulfurizing agent containing a large amount of hydrogen sulfide and other sulfide) is from the bottom of absorption tower 3
It is transported to by circulating pump 35 in regenerator 5, desulfurizing agent rich solution enters from the top of regenerator 5, using air blower 57 by air
It is delivered to through ventilation line 56 in regenerator 5, the efficient composite catalyst in regenerator 5 of the oxygen in desulfurizing agent rich solution and air
In the presence of oxidation regeneration reaction occurs, the hydrogen sulfide in sulfur removing pregnant solution and other sulfide-oxidations is rich into sulphur, desulfurizing agent
Liquid becomes lean solution, and now the sulphur foam in regenerator 5, which flows automatically, enters sulphur foam tank 6, and the sulphur in sulphur foam sinks naturally in sulphur foam tank 6
Form sediment, the lean solution in regenerator 5 flows automatically to surge tank 4, sulphur natural sedimentation in surge tank 4 in lean solution, when in surge tank 4
Lean solution therein is pumped into absorption tower 3 by circulating pump 34 when lean solution reaches certain liquid level and continues to absorb in sulfur-containing gas
Hydrogen sulfide and other sulfide；Finally, the sulphur of regenerator 5, sulphur foam tank 6 and the bottom of surge tank 4 is deposited in, passes through sulphur foam pump
81, which pass through back sulphur pipeline 8, enters solid-liquid separator 7, and the lean solution isolated enters reservoir 9, and the sulphur solid particle isolated is through solid
Body outlet 71 is removed；In addition, the Novel anti-blockage desulfurizer 100 in sweetening process due to the band liquid and water of drusen
Evaporation, the desulfurizing agent in each retort can produce partition losses, and the desulfurizing agent of loss can be supplemented by reservoir 9, when
When liquid level in reservoir 9 is relatively low, then the desulfurizing agent of suitable dosage is supplemented to reservoir 9 in time by fluid infusion pipeline 94.
Novel anti-blockage desulfurizer provided by the utility model has the beneficial effect that：The Novel anti-blockage desulfurizer
Sulphur acquisition rate is high, the desulfurizing agent lean solution in regenerator can not only be carried out into secondary precipitation by surge tank, moreover it is possible to will buffer
Desulfurizing agent lean solution in tank after secondary precipitation is transmitted back in absorption tower again, so as to complete desulfurizing agent from absorption tower-regeneration
Circulating for tower-surge tank-absorption tower, reduces the generation of waste liquid in sweetening process, waste gas；In addition, desulfurization in surge tank
The secondary precipitation of agent lean solution, the desulfuration efficiency of the desulfurizer is on the one hand improved, on the other hand also can effectively prevent desulfurizing agent
The sulphur not precipitated completely in lean solution enters in absorption tower, blocks absorption tower pipeline.
