Description
Technical field
The present invention relates to a kind of fine chemical product, refer specifically to a kind of liquid fire coal additive.
Background technology
Coal is a kind of important energy and raw material, is the main fuel of Industrial Boiler.But traditional coal-fired mode has perhaps
Many shortcomings, as fat coal burns endless, colm cannot utilize, and pollutant emission is serious etc. on the impact of environment.In order to overcome
Above-mentioned deficiency, present way be the combustion characteristics according to this coal, caloric value, volatility and catch fire, sulphur content, slagging scorification
Property, the combustion index such as after-flame, by Coal rank according to a certain ratio, and add forming agent, sulphur-fixing agent, produce different performance, combustion
Burn completely, the less Filter Tuber For Clean Coal of pollutant emission.
But, improve burning of coal quality, the fire box temperature of raising Industrial Boiler and the thermal efficiency, minimizing the most further and give up
The discharge capacity of slag waste gas, improve the utilization rate of the discarded coal in colm even colliery, be still significant.
Summary of the invention
It is desirable to provide a kind of liquid fire coal additive, it can improve ignition temperature and the thermal efficiency, reduce slag
Phosphorus content, reduces slag carbon dioxide and the discharge capacity of flue dust, and makes full use of discarded coal.Save fat coal resource, thus
Save the consumption of coal and reduce the coal combustion pollution to environment.Additionally, liquid additive overcomes again the shortcoming that solid adds, only
Need conveying coal belt feeder on add one strength spray equipment and spray flux proportional with upper coal amount, easy to operate effect
Rate is high, and spraying is uniformly.
For solving above-mentioned technical problem, the technical scheme is that
A kind of liquid fire coal additive, including the raw material of following mass percent: 0.5%～2% cerous nitrate, 1%～5%
Sodium chloride, 10%～50% sodium nitrate or potassium nitrate, 10%～30% Neutral potassium chromate, the deionized water of surplus.
Preferably, a kind of liquid fire coal additive, it is characterised in that containing 2 water of crystallization in described Neutral potassium chromate.
Preferably, liquid fire coal additive, be made up of the raw material of following mass percent: 2% cerous nitrate, 2% sodium chloride,
18% sodium nitrate, 15% Neutral potassium chromate, the deionized water of surplus.
Preferably, liquid fire coal additive, when liquid fire coal additive and coal are used in mixed way, mass ratio is 1:800～900.
In the liquid coal-fired sulfur fixing agent of the present invention, cerous nitrate, Lanthanum (III) nitrate can reduce burning of coal activation energy, play catalysis and make
With, improve solid sulfur conversion rate.Combustion-supporting Degradation is played in sodium nitrate, potassium nitrate.Sodium chloride plays effect combustion-supporting, bulk, can
So that metal oxide lattice is reset, it is formed with pore size distribution and the aperture size of beneficially sulphur-fixing agent, and sodium chloride itself also rises
Sulfur fixation.Sodium chromate, the chromium ion of Neutral potassium chromate are in complexation steady statue, can clear up and suppress the dioxy that coal burning produces
Change sulfur gas, and stablize sulfur retention products metathesis reaction does not the most occur, play catalysis, suppress, stable sulfur and carrying admittedly
High sulphur-fixing agent captured sulfur result effect.
The coal-fired sulfur fixing agent of the present invention uses sodium chromate, Neutral potassium chromate, and activation compounding with other compounds, modification form, and use
Reacting the most rapidly in sulphur coal, catalytic fuel fully burns, with fire coal in generate sulfur dioxide gas precursor reactant,
Playing inhibitor effect in sulphur-fixing agent, it at high temperature forms silicate melt with sulfur retention products, prevents the subdivision of sulfur retention products
Solve, improve sulphur-fixing agent desulfurization efficiency, thus reach to be catalyzed, suppress, stably consolidate the effect of sulfur.Sulphur-fixing agent sweetening process is at coal-fired kiln
Carrying out in (stove) alkalescence atmosphere, in sodium chromate or Neutral potassium chromate, Cr+6 has strong oxidizing property, sulfur dioxide absorption, is oxidized to list
Matter sulfur, together collects with flying dust, reenters calcining in kiln (stove), in sulphur-fixing agent under catalyst action, complexing of metal ion
Sulfur dioxide and oxygen, solidification generates sulfate or sulfite product, by sodium chromate or Neutral potassium chromate inhibitor effect, at kiln
Under (stove) high temperature, and sulfur retention products forms silicate melt, prevents the double decomposition of sulfur retention products, it is achieved improve desulfurization efficiency mesh
's.In the present invention several raw materials with the use of, there is sulfur fixation simultaneously, and promote speed-raising solidification each other, play solid sulfur and fold
Add effect, sulfur environmental protection can not only be consolidated, and coal can be helped fully to burn, improve sulfur-fixing rate.Compared with prior art, this
Bright advantage is: this liquid fire coal additive not only makes coal fully burn, and can the solid sulfur of environmental protection.Sulfur-fixing rate is also than existing skill
Art is high.Through on probation, the present invention reduces burning of coal activation energy, to saving coals from boiler more than 5%, Gu sulfur reaches 40-60%.
Detailed description of the invention
In order to be more fully understood that the present invention, describe technical scheme in detail with instantiation below, but this
Invention is not limited thereto.
It is limited to this.
