Description
Technical field
The present invention relates to a kind of high-efficiency environment friendly coal additive, also relate to the preparation method of this coal additive.
Background technology
Coal or a kind of important energy source of China also are a kind of disposable energy simultaneously at present, and reserves constantly reduce, and because of its burning generation SO
2,CO
2And flue dust etc. also is the more serious energy of a kind of burning and exhausting damage ratio.How to improve coal efficiency of combustion, reduce pollution emissions, be the technical problem that people thirst for solving.People attempt improving with coal additive the combustion and emission of coal now, some technical schemes have also been proposed, such as the coal additive patent of invention of patent No. 200610032354.X, the coal energy-saving clean proliferating agent patent of invention of the patent No. 200910043153.3 etc.But, all there are some defectives in existing these technical schemes: single effect is better, net effect is poor, and the often emission effect that improves emphatically efficiency of combustion is relatively poor, simultaneously fine smoke elimination, solid sulphur, inhibition, solves emphatically the often fine raising efficiency of combustion simultaneously again of emission problem.The coal additive of a kind of not only efficient but also environmental protection of market demand.
Summary of the invention
The object of the present invention is to provide a kind of high-efficiency environment friendly coal additive.Another object of the present invention is to provide a kind of method for preparing this high-efficiency environment friendly coal additive.
In order to solve the problems of the technologies described above, its component of high-efficiency environment friendly coal additive of the present invention and weight part thereof are: the tea dregs of rice or Semen Brassicae campestris slag 2-15 part, slag 5-33 part, SPC-D 0.5-2 part, Potcrate 0.8-4 part, potassium perchlorate 1-8 part, sodium-chlor 2-8 part, hydrated barta 4-12 part, light magnesium oxide 1-5 part, Manganse Dioxide 0.1-1.7 part, nano titanium oxide 0.5-2.5 part, humic acids 1-21 part.
High-efficiency environment friendly coal additive of the present invention can add in the various inferior coals.
Greater than 1.5% coal, the ingredients weight parts of used described coal additive is preferably: the tea dregs of rice or Semen Brassicae campestris slag 2-15 part, slag 5-33 part, SPC-D 0.5-2 part, Potcrate 0.8-4 part, potassium perchlorate 1-8 part, sodium-chlor 2-8 part, hydrated barta 4-12 part, light magnesium oxide 1-5 part, Manganse Dioxide 0.1-1.7 part, nano titanium oxide 0.5-2.5 part, humic acids 1-14 part for sulphur content.
Less than 1.5% coal, the ingredients weight parts of used described coal additive is preferably: the tea dregs of rice or Semen Brassicae campestris slag 6-10 part, slag 20-33 part, SPC-D 1-1.5 part, Potcrate 1.1-3 part, potassium perchlorate 5-8 part, sodium-chlor 5-8 part, hydrated barta 7-10 part, light magnesium oxide 3-5 part, Manganse Dioxide 0.3-0.7 part, nano titanium oxide 1.5-2 part, humic acids 14-21 part for sulphur content.
Ingredients weight parts the best of described coal additive is: 9 parts of the tea dregs of rice or Semen Brassicae campestris slags, 27.5 parts in slag, 1 part of SPC-D, 2.5 parts in Potcrate, 5 parts of potassium perchlorates, 6 parts in sodium-chlor, 7 parts of hydrated bartas, 3 parts of light magnesium oxides, 0.5 part of Manganse Dioxide, 1.5 parts of nano titanium oxides, 14 parts of humic acidss.
The tea dregs of rice or Semen Brassicae campestris slag are the residues after the oil crops oil expression, a little oil gas is still contained in the inside, has extraordinary combustibility, is again natural raising agent, mix burning with raw coal boiler noncoking and slag are not lumpd, have simultaneously effect combustion-supporting, that improve thermo-efficiency.Can be directly used in power station stove, boiler oil.
Slag is natural raising agent, and it can make, and furnace wall noncoking, eutectic decomposition temperature reduce, decomposition rate is accelerated, and ash-removal effect is obvious, can improve combustion-supporting and smoke elimination, sweetening effectiveness.
The combustion-supporting ash-removal effect of SPC-D is obvious.
Potcrate is oxygen raw material processed, can improve the efficiency of combustion of coal, is ignition dope.
Potassium perchlorate both had been that smoke suppressor also is ignition dope.
Sodium-chlor not only has combustion-supporting effect, and chemical reaction keeps stable can make coal burning again the time, avoid coal-fired in burner hearth the intensity of a fire dynamic, fluctuated.
In the hydrated barta energy and the carbonic acid gas that coal burning produces in the boiler, reduce Carbon emission.
Manganse Dioxide, light magnesium oxide as sulphur-fixing agent, have shortened the time that generates vitriol under the furnace high-temperature condition, have improved solid sulphur sweetening effectiveness.
Nano titanium oxide is a kind of efficient denitrfying agent.
Humic acids [R-(COOH)
N] the special roles such as ion exchangeable, oxidation-reduction quality of carbonyldioxy, phenolic group isoreactivity group, promote burner hearth inner metal surface Fe
3O
4Anticorrosion, corrosion inhibition is played in the formation of protective membrane.
Coal additive of the present invention is take the tea dregs of rice or Semen Brassicae campestris slag and slag as carrier, abundant raw material, and cost is low.Add coal additive of the present invention in inferior coal mixed firing by weight the ratio of 1:99, can oxygen enriching burning-aid, to improve the efficiency of combustion of coal, the combustion time that prolongs coal, burning more abundant, can make nonflammable low grade coal reach the combustion efficacy of fat coal, detect through energy-conservation department: boiler slag carbon content can be reduced to 2.1%, can reduce by 58.7%, and boiler thermal output can be brought up to 98.88%, can improve 7.88%; Simultaneously, can effectively be deposited on the non-metallic elements such as the sulphur in the coal, phosphorus in the slag, can reduce the quantity discharged of the obnoxious flavour such as dust-exhausting quantity and sulfurous gas behind the stove, detect through environmental administration: its solid sulphur desulfurization degree can reach more than 95.6%, can reduce carbon monoxide 50%, be reduced to 22%, deashing, smoke elimination, corrosion mitigating effect are obvious; And can make that slag is loose, the deslagging noncoking, and reduce kettleman's the labour intensity such as slagging-off, improve the working conditions of boiler house.Coal additive of the present invention not only efficiently but also environmental protection.
The method of the described high-efficiency environment friendly coal of preparation provided by the invention additive comprises the steps: the 40-60 order is mixed, is crushed to described component raw material by described part by weight, puts into the stirrer stirring again and gets final product in 5-10 minute.The preparation method is simple and convenient, and cost is low.
Coal additive of the present invention also can prepare with blending means commonly used.
