Description
Technical field
The present invention relates to desulfurizing agent production technical fields, more specifically to the production technology of ferric oxide desulfurizer.
Background technique
Many occasions in the industrial production can all generate sulfide.Such as, industrial chemicals is being produced with coal or petroleum
Production process in and general industry production discharge waste water or exhaust gas in.Wherein, chemical industry is being produced with coal or petroleum
In the production process of raw material, the hydrogen sulfide generated is mainly due to containing more sulphur-containing substance in raw material, so that the sulfur-bearing
Substance reacts in process of production and releases hydrogen sulfide, to directly result in catalyst activity object in subsequent production workshop section
Matter poisoning and deactivation.In addition, hydrogen sulfide sulfides contained in the waste water or exhaust gas that are discharged in industrial production, if directly
Row will seriously affect environment, even cause person poultry poisoning.
Currently, researcher is to efficiently reduce destruction of the above-mentioned sulfide to industrial production and environment, for de-
The research and development of sulphur agent give enough attention.Desulfurizing agent various types in the prior art, it is most to be aoxidized with Fe-series desulfurizing agent, manganese
Based on object desulfurizing agent, solid base/liquid base desulfurizing agent, activated carbon desulphurization agent or molecular sieve active metal desulfurizing agent.Wherein, iron
Fimily desulfurizing agent is more traditional one of desulfurizing agent, and the type desulfurizing agent is mainly the active group using ferriferous oxide as desulfurizing agent
Point.
The exhaust gas generated in the industrial production is mostly high temperature and the exhaust gas containing sulfide, and it is de- that iron oxide generally can be used
Sulphur agent is handled, the ferric oxide desulfurizer of conventional extrusion, although there are many holes for meeting, for the suction for sulfide
It is attached, realize desulfurization, but desulfurizing agent is with the extension of use time, meeting of the desulfurizing agent inside same desulfurizing agent relative to outside
Preferably, but since long-time uses, the aperture of hole is gradually become smaller, or even is plugged, so that hole quantity gradually tails off, leads
Desulfurizing agent inside causing is difficult to play a role, and service efficiency and desulfuration efficiency is caused to reduce.
Summary of the invention
1. technical problems to be solved
