Abstract
This purifying agent takes dolomite, limestone, boron mineral, copper ore slag, alumina, iron ore slag, industrial salt, potassium carbonate and sodium nitrate as raw material. They are ground to size smaller than 0.5 mm and mixed in definite proportion. During application, purifying agent and coal are in the ratio of (5-8):10. This purifying agent can make the coal ignite carlier, burn completely, eliminate the smoke and lower the amount of NOx and SOx exhaust.
Description
The present invention relates to a kind of high efficient coal-saving decontaminating agent, belong to the burning of coal technical field.
China is coal storage, producing coal and coal-fired big country, and the coal of nearly 70%-80% is directly used in burning, and wherein 38% (about 3.5 hundred million tons of coals) are used for 450,000 Industrial Boilers.According to the statistics in Shanghai City and Jiangsu Province, its operational efficiency is about 65%, about about 100,000,000 tons of year waste coal.Industrial Stoves year is consumed about about 200,000,000 tons of coal, and incomplete combustion loss is about 25%, adds because of processing requirement starts frequently, and actual operating efficiency is not as good as 50%, and this loss also reaches about 100,000,000 tons of coals.About about 100,000,000 tons of the civilian coal yearly consumption of China, their efficient is very low, wastes also surprising.300,000,000 tons of the annual coal consumptions of heat power station, wherein the efficiency of combustion of low-volatile coal is also lower, and combustion instability.
In recent years, the Chinese government has carried out conscientious research and tackling key problem to efficient, low pollution coal combustion technology, has obtained significant achievement, and especially the pulverized coal combustion of station boiler has been obtained breakthrough progress.But the coal-fired situation for Industrial Boiler that has a large capacity and a wide range and kiln does not improve significantly, and the wastes and pollution situation is still very serious.Fluidized bed combustion provides modern technique for thoroughly improving this situation.But the coal-fired industry stove of existing hundreds of thousands of platform will be unpractical with fluidized bed combustion transformation.For this reason, scientific and technological work person is still in the various new combustion techniques of research, to obtain less investment, effective Industrial Boiler and kiln coal combustion technology.To the research of this problem, two technological lines are arranged substantially at present: the one, rationalization's furnace air flows, and strengthens heat transfer and burning to coal, reaches the purpose of energy-saving and pollution-reducing; The 2nd, studying coal-fired additive improves the burning of coal characteristic from chemical aspect.
Existing one of the purification techniques of economizing on coal as the additive for fire coal of Chinese patent 87100631.4 reports, is a main raw material with the coal gangue, is aided with other slag again, and its proportioning components is:
Industrial inorganic residue (coal gangue etc.): 100 kilograms
Wingdale: 10-30 kilogram
Silicate: 10-15 kilogram
Chimney soot: 10-15 kilogram
Salt: when the 5-15 kilogram used, the ratio of additive and coal was 80: 100, this shows, used the purification additive of economizing on coal of prior art, its cost height, and effect is also relatively poor.
The objective of the invention is to develop a kind of new high efficient coal-saving decontaminating agent, in coal, add compounds such as alkaline metal salts such as sylvite, sodium salt, calcium salt, manganese salt and copper, iron, nickel, make it in burning of coal, play catalyzed reaction, quicken the reaction process of carbon and oxygen, make catching fire in advance of coal, burning is complete, the elimination of smoldering, and the quantity discharged of NOx, SOx is descended to some extent.
The high efficient coal-saving decontaminating agent of the present invention's development, its proportioning components is:
Rhombspar: 10%～20% industrial table salt: 8%～12%
Wingdale: 10%～20% salt of wormwood: 6%～12%
Boron mud: 10%～30% SODIUMNITRATE: 8%～10%
Copper mine slag: 8%～15% aluminium vanadine: 8%～10%
The iron ore slag: the granularity of 8%～12% above-mentioned various materials is＜0.5mm, and being mixed is the high-efficient coal-saving scavenging agent, and scavenging agent is 5～8: 100 with coal-fired use proportioning.
Embodiments of the invention are as follows:
Embodiment 1:
Rhombspar: 10% iron ore slag: 8%
Wingdale: 20% industrial table salt: 10%
Boron mud: 10% salt of wormwood: 6%
Copper mine slag: 8% SODIUMNITRATE: 8%
Aluminium vanadine: 10%
Embodiment 2:
Rhombspar: 15% iron ore slag: 8%
Wingdale: 10% industrial table salt: 9%
Boron mud: 15% salt of wormwood: 9%
Copper mine slag: 15% SODIUMNITRATE: 9%
Aluminium vanadine: 10%
Embodiment 3:
Rhombspar: 15% iron ore slag: 10%
Wingdale: 15% industrial table salt: 12%
Boron mud: 15% salt of wormwood: 7%
Copper mine slag: 10% SODIUMNITRATE: 8%
Aluminium vanadine: 8%
Embodiment 4:
Rhombspar: 10% iron ore slag: 11%
Wingdale: 18% industrial table salt: 8%
Boron mud: 15% salt of wormwood: 10%
Copper mine slag: 8% SODIUMNITRATE: 10%
Aluminium vanadine: 10%
Among above-mentioned four embodiment, the granularity of material is all less than 0.5mm.
Behind above-listed four kinds of additives to a few chain of stations bar ovens and 2 pulverized coal firing boiler interpolations 5%, its effect is as follows: the furnace flame medial temperature improves 100 ℃～200 ℃, and boiler thermal output improves 6.7%～17.3%, and coal saving rate is 10.6%～23.5%; SO
2Quantity discharged reduces by 8.9%～17.39%; The NOx quantity discharged reduces by 22.4%～26.5%.
After using scavenging agent of the present invention, catch fire in advance, the furnace flame temperature improves about 100 ℃ approximately, is in boiler about 75% for boiler thermal output, and it is about about 10% generally to improve thermo-efficiency, and coal saving rate is 15%～20%, and the blackness of cigarette descends significantly; SO
2With NO
2Quantity discharged has reduction in various degree.
Scavenging agent of the present invention is raw material with the trade waste, low price not only, and turn waste into wealth, improved environment.Scavenging agent of the present invention is applicable to chain furnace and other Industrial Boilers, also can be used in coal-powder boiler and the moulded coal stove.
