Sulphur lean solution is by the solution of the material compositions such as alkali, catalyst, water, and desulfurization lean solution squeezes into desulfurizing tower top by lean pump, and upper
Contain H in portion2The gas of S inversely contacts.Wherein, H2S absorbed by lean solution after as solution is discharged into rich solution slot together, by rich solution pump
It send in the injector to above regeneration tank, in course of injection entrainment of oxygen in pipeline inflow regeneration tank lower part, rich solution
Sulphur hydrogen radical ion generation elemental sulfur is reacted with oxygen, in the form of sulphur foam after emersion liquid level overflow to sulphur foam collecting tank
In, then industrial sulphur is obtained through sulphur of superfusing；The solution gone after sulphur removal foam flows back to lean liquid tank and continues cycling through use again.It crosses herein
Cheng Zhong, rich solution is contacted by injector with the oxygen in air occurs oxidation reaction, it is achieved thereby that sulfur regeneration, but do not participate in
The nitrogen of reaction, the H being precipitated on a small quantity2The S and SO of side reaction generation2The drain that regeneration gas is waited to pass through at the top of regeneration tank
Discharge, these regeneration gas are directly discharged into air, pollute environment.
At present, in industry the design of desulfurization regeneration slot generally using the above scheme, but with country to environmental requirement not
Disconnected to improve, these pernicious gases forbid direct emission.In order to ensure these regeneration gas qualified discharges, need to design one
