Sulfur elimination in the utility model selects the amorphous FeOOH particle with larger pore volume and specific surface area,
Each iron atom is surrounded by the octahedron (oxygen atom composition) of a distortion in the amorphous FeOOH, and these are octahedra
It is connected with each other again and constitutes foldable layer, hydrogen atom is not in this structure, and is adjacent to around oxygen atom, is embedded in O
Between OH, the oxygen atom in folding it is equal with the distance of 4 iron atoms (2 iron atom spacing are 1.93pm, in addition 2
Individual iron atom spacing is 2.13pm).However, can only be connected by two iron atoms positioned at the atom for folding layer surface, two
The distance of iron atom is 2.05pm, and the distance of oxygen atom is 2.72pm in foldable layer.Therefore, beyond each folding layer surface only
There are OH key groups, hydrogen bond is existed only in OH key groups, two hydrogen bonds are formed between each group of OH key group.
Because amorphous FeOOH has special structure, some very small crystal or unformed are can be only formed
Body, thus with larger specific surface area, form the little hole in Numerous aperture, it is also possible to the room on surface is formed, thus
Have higher desulphurizing activated.Unformed FeOOH is in neutrality, at normal temperatures to H2S has very strong affinity.Reacted
Hydroxyl (- OH) and H in Cheng Zhong, FeOOH2HS after S dissociations is replaced and is generated FSSH, sees reaction equation:
Desulfurization:FeOOH+2H2S=FeSSH+2H2O
That is, high efficiency amorphous FeOOH reacts in desulfurizing tower with the hydrogen sulfide in natural gas, mercapto is generated
Base iron sulfide and water, so as to by the hydrogen sulfide stripping in natural gas.
In sum, emission-control equipment is introduced into produced gas in desulfurizing tower in the utility model, makes desulfurizing agent with sulfuration
Hydrogen is combined, and under the promoting of catalyst so that hydrogen sulfide gas react rapidly with desulfurizing agent, hydrogen sulfide gas quilt
Fully absorption, effectively keeps the stability of gas, finally realizes hydrogen sulfide qualified discharge.And the waste gas in the utility model
Processing meanss are workable, and the term of validity is long, can greatly reduce labour cost.Desulfurizing tower adopts dry desulfurization, inside sulfuration
The hydrogen inorganic agent replacement cycle is long, compared with traditional desulfurizing agent, greatly reduces the labour intensity of live employee.
Separately, device internal-response medium is solid particle, can not be volatilized out under normal temperature after inorganic agent saturation, to environment, people
Body is without impact.Discarded object after desulfurization is reclaimed by producer, and the scientific research technology gone out using producer's recent studies on is used high-efficiency adsorbent
Useless agent afterwards grinds to form particle, obtains useless agent powder, then useless agent powder is made into into suspension by adding certain chemical raw material, then
It is passed through oxygenous gas to be aoxidized, makes the iron sulfide in suspension be converted into amorphous FeOOH and elemental sulfur.
Effective recycling has been carried out to resource, the reluctant difficult problem of discarded object has been solved, the harm to environment has been reduced.
Emission-control equipment, without the need for being powered, meets what country advocated without any mechanical action, noiselessness in the utility model
Energy-saving policy, can save more resources.
