Description
Technical field
The present invention relates to a kind of coal additive technical field, be specifically related to the coal synergist of a kind of high-efficiency environment friendly.
Background technology
Along with industrialization, Development of China's Urbanization accelerates and consumption structure is persistently upgraded, and China's energy demand is that rigidity increases, and is subject to
Domestic Resources supportability and environmental carrying capacity restriction and global energy security and reply climate change effect, resource environment is about
Bundle is strengthened increasingly.China be one using fire coal as the country of main energy sources, the consumption figure of coal accounts for the 70% of energy-consuming, coal
A large amount of use bring two large problems: one is energy efficiency problem, and two is environmental problem.The terminal utilization ratio of China's coal at present
Being about 41%, efficiency of fire coal is low, and energy waste is big.A large amount of fire coals cause again atmospheric pollution, coal-fired a large amount of discharge comprise CO, VOC,
NOx、SOx, the waste gas of the noxious pollutant such as microgranule, cause serious air pollution, carbon emission amount significantly to exceed standard, to human survival
Environment directly produces threat.
In today of energy scarcity, effectively, reasonably utilize existing resource, improve the thermal efficiency of coal, improve coal-fired profit
By efficiency, it is self-evident for alleviating environmental pollution to the importance of national economy.Have people at present and use coal catalyst
Improve the combustion efficiency of coal, but consumption is relatively large.At present, the mechanism of coal catalysis burning is primarily formed two kinds of theories,
I.e. oxygen transmission theory and electron transfer theory.Regardless of whether which kind of theory is directed to catalyst or their catabolite is formed
Chain carrier, chain carrier increases, and burning is necessarily accelerated and carries out completely.And in order to increase chain carrier
Quantity, it is necessary to increase catalyst consumption, and increase catalyst surface area.When rolling up the consumption of catalyst,
On the one hand the use cost of catalyst can be improved；On the other hand, owing to consumption is excessive, catalyst can block the capillary on coal surface
Hole, the combustibility being easily caused coal on the contrary declines.Therefore, research and development one adds just can make coal burning imitate on a small quantity
Substantially, the coal combustion synergist that noxious pollutant discharge greatly reduces becomes focus and the direction of this area to fruit.
Summary of the invention
The technical problem to be solved is to provide the coal synergist of a kind of high-efficiency environment friendly, this synergist, catalysis
Combustion efficiency is obvious, it is possible to reduce the ignition point of coal, promotes that coal burns completely, reduces discharge amount of exhaust gas.
For achieving the above object, the present invention adopts the following technical scheme that
The coal synergist of a kind of high-efficiency environment friendly, is made up of the raw material of following percentage by weight:
Preferably, the coal synergist of the high-efficiency environment friendly of the present invention, it is made up of the raw material of following percentage by weight:
Preferably, the Baume degrees of black liquid of the present invention is 35～45 ° of B é.The alkaline black liquor of paper mill discharge contains
There is a large amount of K2CO3, Na2CO3, KOH, NaOH and Ca (OH)2Deng, there is good combustion catalysis effect, by dry black liquid
In appropriate addition coal, the ignition temperature of coal can be made to reduce by 30 DEG C～50 DEG C, promote coal completely burned off, it addition, it also has desulfurization to make
With, desulfurization degree can reach 35%～58%, is conducive to protecting environment.
Preferably, the Baume degrees of alkali factory waste liquid of the present invention is 40～48 ° of B é.Containing a large amount of in alkali factory waste liquid
CaCO3With a small amount of CaCl2, it being suitably added this waste liquid and be conducive to coal ignition, also there is desulfidation simultaneously, desulfurization degree can
Reach more than 44%.
For ensureing the performance of synergist, it is preferable that the particle diameter of Iron Ore Powder of the present invention is 10～20 μm.Iron ore exploitation
During produce iron ore powder, wherein rich in Fe2O3, it is preferable coal combustion catalyst raw material, some iron mine tors do not possess out
Adopt value, through air slaking for many years, the substantial amounts of iron ore of the many accumulations in hillside, use, abundance can be collected.
In the formula material of the present invention, isopropanol, ethanol, the tert-butyl alcohol are volatile ingredient, advantageously reduce catching fire of coal
Point, plays good combustion-supporting effect；Containing substantial amounts of alkali metal salt in black liquid, alkali metal ion therein embeds carbon lattice
Inside, make the microstructure of carbon change, and as electronq donor, move accelerating part reactions steps by electronics,
Thus improve the speed of whole reaction, make carbon burning obtain more complete, take full advantage of coal resources, reduce the discharge of pollutant；
Acetone has obvious combustion-supporting effect；Alkali factory waste liquid contains a large amount of calcium, during coal burning, the sulfur dioxide of generation, sulfur trioxide with
Calcification synthesis calcium sulfite, calcium sulfate, be fixed in lime-ash, in its course of reaction, discharge substantial amounts of heat energy, make ignition temperature
Improve, promote original aphlogistic composition in coal, play combustion-supporting and catalysis combustion, make the boiler slag carbon content after burning
Decline；Fe in Iron Ore Powder2O3Provide burning initial stage required oxygen for feed coal in combustion, improve coal
The burning velocity of granule, reduces coal ignition point, promotes burning and reduces the discharge capacity of pollutant, it is also ensured that in boiler
Combustion case and load of exerting oneself, take full advantage of coal resources.
The beneficial effects of the present invention is:
1, burning velocity can be accelerated, improve efficiency of combustion.
2, ignition point and the bed of material ignition temperature of coal can be reduced, promote burning.
3, promote that coal burns completely, make full use of coal resources, reduce the discharge capacity of pollutant, protect environment.
4, volume is few, it is only necessary to mix coal gross weight 0.01～0.07% i.e. can reach good combustion efficiency.
5, black liquid and alkali factory waste liquid are to pollute the most serious garbage, collect recycling, turn waste into wealth, and reduce
Cost, also helps protection environment.
