Description
Technical field
The present invention relates to a kind of novel sulphur-fixing agent, belong to control atmospheric pollution technical field.
Background technology
Coal is one of main energy sources of China, is also to apply the most common energy former in modern industry
Material, but its main Land use systems is burning, and burn and can produce flue dust, sulfur dioxide (SO2)、
NOxEtc. atmosphere pollution.The acid rain etc. that these atmosphere pollutions are easily formed, causes atmospheric environment
Great harm, has had a strong impact on the quality of environment for human survival, has destroyed ecological balance.For solving
Certainly this technical barrier, China uses coal combustion and sulfur fixation technology to control sulfur dioxide (SO2) discharge,
Reduce atmospheric pollution.
At present, the sulfur solidifying technique of domestic coal-burning power plant has: desulfurization before combustion, sulphur fixation in coal combustion and flue gas desulfurization.
Wherein, desulfurization before combustion can remove the inorganic sulfur of 40%～60%；Though desulfurization desulfurized effect is good after combustion, de-
Sulfur rate is up to more than 80%, but owing to investment is big, operating cost is high, and waste gypsum after desulfurization
Problem of outlet, limits the application of its enterprise at home to a certain extent；Desulfurization in combustion, in fire coal
Increase sulphur-fixing agent and can control sulfur dioxide (SO2) discharge, convenient and easy, small investment and operation
Expense is low.Wherein, calcium based sulphur-fixation reagent is the most frequently used sulphur-fixing agent, and this is owing to calcium based sulphur-fixation reagent is cheap
It is easy to get.Common calcium based sulphur-fixation reagent has limestone, dolomite, quick lime etc., and it is mainly by oxygen
Change calcium (CaO) sulfur dioxide absorption (SO2), generate calcium sulfate (CaSO4), it is achieved control two
Sulfur oxide (SO2) purpose discharged.But under conditions of high temperature, sulfur retention products calcium sulfate (CaSO4)
Easily twice decomposition, reduces sulfur-fixing rate.
In order to solve this technical barrier, people carry out in-depth study to sulphur-fixing agent.In recent years, people
On sulphur-fixing agent, obtain certain Research Achievement, as Chinese patent CN 1252229 C disclose " combustion
Coal compound sulphur-fixing agent and preparation method thereof ", this sulphur-fixing agent is by being ground into compound less than 1mm of granularity
Carbonate, calcium carbonate, calcium oxide and magnesium carbonate uniformly mix composition, can be respectively in different ignition temperatures
The sulfur dioxide that section produces in fully absorbing coal furnace, thus reach to reduce in coal fire discharged flue gas
Content of sulfur dioxide, reduces the purpose of environmental pollution.Although this sulphur-fixing agent component raw material is easy to get, preparation
Simple process, low production cost, but its sulfur-fixing rate less than ideal under the high temperature conditions, this
Hinder popularization and the application of sulphur-fixing agent to a certain extent.Therefore, continue to explore and research sulphur-fixing agent
It is the most valuable.

Vanadic anhydride, niobium pentaoxide, the mesh number of aluminium powder are 100～200 mesh；Described nano-silica
Change titanium, the particle diameter of nano-calcium carbonate is 50～100nm.
The novel sulphur-fixing agent principle of the present invention is as follows: after firming agent and coal are sufficiently mixed, and adds burner hearth
In burn, in combustion process:
1, when temperature is less than 300 DEG C, ethanol can promote coal combustion, improves calory burning, meanwhile,
Bentonite, zeolite, kieselguhr have good adsorptivity, can adsorb release air in combustion process
Pollutant；
2, when temperature 300～500 DEG C, it is raw that calper calcium peroxide can discharge oxygen in combustion
Become calcium oxide, the H that oxygen can be decomposed to form fat sulfur in coal2The gas oxygen chemical conversions such as S, COS
SO2, then react with the calcium oxide in the calcium oxide generated and raw material, generate CaSO4；
3, when temperature 500～950 DEG C, first, Pulvis Talci forms molten silicate body, and is coated with
On surface, with perlite because of thermal expansion build inside fire coal oxygen-enriched atmosphere mutually promote, thus
Realize solid sulfur purpose.Secondly, ferrum oxide can promote the sulfur fixation of solid sulfur composition, oxidation in coal ash
Zinc is sulfur fixation in reducing atmosphere, and with the solid sulfur of form of ZnS, in oxidizing atmosphere, oxidation
Calcium plays sulfur fixation, and with CaSO4The solid sulfur of form, meanwhile, ferrum oxide, zinc oxide also rise
To catalytic action.Then, barium hydroxide can form BaSO with oxysulfide4, BaSO4Can be with it
His sulfate formation eutectic, makes coal-fired structure change, and hole increases, increase oxysulfide with
The contact area of sulphur-fixing agent, thus improve sulfur-fixing rate.Finally, vanadic anhydride, potassium sulfate and diatom
There is coordinative role in soil, makes sulfur dioxide become sulfur trioxide, so that it is formed stable with firming agent
Compound, and then improve sulfur-fixing rate；
4, when temperature is more than 1100 DEG C, first, Kaolin, cordierite can be with calcium oxide, oxidations
The composition generation solid state reactions such as ferrum, form 3CaO.3Al2O3.CaSO4、2CaO.Al2O3.SiO2、
CaFe3(SiO4) high-temperature-phase such as OH, thus improve sulfur-fixing rate at high temperature；Meanwhile, Kaolin, bentonite,
Na in perlite, cordierite+、K+、Mg2+Plasma, it is possible to cause more crystal defect, have
It is beneficial to Ca2+Diffusion, improves sulfur-fixing rate.Secondly, strontium carbonate resolves into strontium oxide, with SOxReaction
Generate SrSO4, improve sulfur-fixing rate further.Again, niobium pentaoxide presents not in different temperature
Same phase, is α phase at 800～900 DEG C, and 1000～1150 DEG C is β phase, and 1200～1250 DEG C are
γ phase.Different phase transformations, changes texture of coal, increases crystal defect, improves sulfur-fixing rate；Then, aluminum
Powder, in coal combustion process, by easily causing microexplosion under high temperature action, makes coal open under the effect of microexplosion power
Split, make coal surface be easier to sulphur-fixing agent and carry out chemical reaction, thus improve sulfur-fixing rate.Finally, receive
Rice titanium dioxide, nano-calcium carbonate make the specific surface area of coal become big, prevent product CaSO4Blocking CaO
The duct on surface, improves sulfur-fixing rate.
Compared with prior art, the invention has the beneficial effects as follows:
1, general sulphur-fixing agent is to be oxidation of the sulfide into CaSO4, this product is easy secondary when high temperature
Decompose.Sulphur-fixing agent of the present invention is by sulfide 3CaO.3Al2O3.CaSO4、2CaO.Al2O3.SiO2、
CaFe3(SiO4) high-temperature-phase such as OH, under these product high temperature, thing is stable mutually, thus improves high-temperature fixed sulfur
Rate.
2, Na in Kaolin, bentonite, perlite, cordierite+、K+、Mg2+Plasma, energy
Enough cause more crystal defect, beneficially Ca2+Diffusion, improves sulfur-fixing rate.
3, niobium pentaoxide presents different phases in different temperature, is α phase at 800～900 DEG C,
1000～1150 DEG C is β phase, and 1200～1250 DEG C is γ phase.Different phase transformations, changes texture of coal,
Increase crystal defect, improve sulfur-fixing rate.
4, aluminium powder is in coal combustion process, by easily causing microexplosion under high temperature action, at the work of microexplosion power
Make coal ftracture under with, make coal surface be easier to sulphur-fixing agent and carry out chemical reaction, thus improve sulfur-fixing rate.
5, improve sulfur-fixing rate, reduce SO2Discharge, decrease atmospheric pollution, also reduce meanwhile
The consumption of the energy.This be due to the present invention sulphur-fixing agent in combustion, not only control SO2's
Discharge, and progressively carry out the solid state reaction of exothermic reaction, reduce heat dissipation, improve the efficiency of coal.
