Abstract
The bitumenite smoke suppressor is suitable for eliminating smoke and dust of various kinds of bitumenite for different types of boiler, kiln and furnace. The bitumenite smoke suppressor is compounded with potassium chloride, sodium chloride, potassium nitrate, sodium nitrate, methanol, ethanol, ether, slaked lime, C12 fatty alcohol polyoxyethylene ether and water in certain weight proportion and through certain technological process. When it is used, the bitumenite smoke suppressor is diluted and spread onto bitumenite. Test shows that the bitumenite smoke suppressor can raise bitumenite burning heat efficiency by over 15 %, save bitumenite by 15 %-25 %, raise the burning area temperature by 150 deg.c and reduce exhaust dust effectively.
Description
One. technical field
The present invention relates to a kind of bituminous coal smoke suppressor, specifically a kind of smoke suppressor that is applicable to various bituminous coal.
Two. technical background
With bituminous coal is the various boilers of fuel, adopts the smoke contamination that method is removed or the minimizing bituminous coal is brought of water film dedusting mostly.But water film dedusting technology and engineering complexity, the cost height.Simultaneously the water film dedusting method just uncombusted in the flue dust or the miniature carbon granules that do not fire, is blocked in the water with moisture film, thereby brings new pollution.And be mixed in other impurity (for example sulphur) in the coal, becomes waste gas through burning, wherein can be water-soluble pass through moisture film the time water-soluble formation new source of pollution.(application number is the patent of invention " combustion-aided dust-removing additive for coal firing " that the inventor was once applied on September 10th, 2004: the additive that 200410073062.1) discloses a kind of energy combustion-aided dust-removing.But it is different types of bituminous coal in application, and dilution is different with the method for using.So just brought inconvenience to application.
Three. summary of the invention
Task of the present invention is: a kind of bituminous coal smoke suppressor is provided, and easy to use to be applicable to various bituminous coal, can eliminate or reduce smoke discharge amount, reduce and pollute, improve efficiency of combustion, economize on coal.
The present invention finishes above-mentioned task with following technical scheme.
A kind of bituminous coal smoke suppressor.By weight percentage, the prescription of this bituminous coal smoke suppressor is as follows: Repone K 5%--10% sodium-chlor 4%--8% saltpetre 3%--7% SODIUMNITRATE 4%--8% methyl alcohol 10%--15% ethanol 6%--11% ether 4%--7% slaked lime 23%--34% water 10%--18%C12 aliphatic alcohol polyethenoxy (4) ether 4%--8%.The production technique of this bituminous coal smoke suppressor is: according to above-mentioned prescription slaked lime and water are hybridly prepared into the mixed solution that contains slaked lime 35%--65.Get quantitative water in proportion, and in this water, add Repone K, sodium-chlor, saltpetre and SODIUMNITRATE in proportion successively, fully stir and be mixed with mixing solutions, slaked lime mixed solution, the Repone K for preparing, sodium-chlor, saltpetre, SODIUMNITRATE mixing solutions and mix by C12 aliphatic alcohol polyethenoxy (4) the ether amount of prescription regulation and are stirred, amount by the prescription regulation adds methyl alcohol, ethanol and ether successively again, stir, promptly make this bituminous coal smoke suppressor.This bituminous coal smoke suppressor should be deposited in and avoid sunlight to be exposed to the sun in the encloses container.
C12 aliphatic alcohol polyethenoxy (4) ether can replace with the polysorbate60 of equivalent in the above-mentioned prescription.
The pH value that dilutes this smoke suppressor institute water is 7.
The using method of above-mentioned bituminous coal smoke suppressor, bituminous coal per ton are added this smoke suppressor 500ml, according to the wet degree of doing of coal, add 30--200 water doubly earlier with this smoke suppressor dilution, then this smoke suppressor behind the dilute with water evenly are sprayed on the used coal, can use.
The present invention has following advantage and effect through testing and trying out.
1. can reduce or eliminate smoke discharge amount effectively, reduce environmental pollution.Because oxygenate content is abundant in this smoke suppressor, can provide the oxygen of capacity to guarantee that coal burns cmpletely, thereby reduce or eliminate imperfect combustion or unburned miniature carbon granules generation and quantity discharged, promptly reduced or eliminated the quantity discharged of flue dust.Contain slaked lime, Repone K, sodium-chlor in this smoke suppressor simultaneously, and these things can be eliminated the flue dust that other impurity are produced through burning in the bituminous coal.Therefore bituminous coal can reduce or eliminate the quantity discharged of flue dust reliably after using this smoke suppressor.Through test, the centering D-type boilerD adds this smoke suppressor, can make its soot emissions reach country and allow emission standard.For kilns such as dwarf boiler, smelting furnace and forging, pottery, refractory materialss, use the bituminous coal flue dust in line, add this smoke suppressor and can make smoke discharge amount reduce more than 70%.
2. this smoke suppressor is applicable to various bituminous coal, and easy to use.No matter the bituminous coal of assorted petty kind, the amount of this additive of use per ton all is 500ml; And all be do the wet degree of elder generation according to coal, add 30--200 water doubly and dilute, then it is sprayed at equably on the coal for using.
3. owing to uses this smoke suppressor to provide competent oxygen as burning of coal, thus sufficient combustion, can make coal owing to use this smoke suppressor to improve thermo-efficiency more than 15%, the combustion fire is distinguished the temperature raising more than 150 °, and 15%--25% is sparing in the use of coal.
4. this smoke suppressor raw material is easy to get, and production technique is simple, and production cost is low.
5. using method is easy, and environmental benefit, social benefit and good in economic efficiency are suitable for popularization.
Four. embodiment
A kind of bituminous coal smoke suppressor.By weight percentage, the prescription of this bituminous coal smoke suppressor is as follows: Repone K %6% sodium-chlor 5% saltpetre 5% SODIUMNITRATE 6% methyl alcohol 12% ethanol 8% ether 6% slaked lime 31% water 15% C12 aliphatic alcohol polyethenoxy (4) ether 6%.The production technique of this bituminous coal smoke suppressor is: according to above-mentioned prescription slaked lime and water are hybridly prepared into the mixed solution that contains slaked lime 58%.Get quantitative water in proportion, and in this water, add Repone K, sodium-chlor, saltpetre and SODIUMNITRATE in proportion successively, stir, be mixed with mixing solutions.Slaked lime mixed solution, the Repone K for preparing, sodium-chlor, saltpetre, SODIUMNITRATE mixing solutions and mix by C12 aliphatic alcohol polyethenoxy (4) the ether amount of prescription regulation and are stirred, amount by the prescription regulation adds methyl alcohol, ethanol and ether successively again, stir, promptly make this coal smoke suppressor.This coal smoke suppressor should be deposited in the encloses container, avoids sunlight to be exposed to the sun.The pH value that dilutes this smoke suppressor institute water is 7.C12 aliphatic alcohol polyethenoxy (4) ether can replace with the polysorbate60 of equivalent in the above-mentioned bituminous coal smoke suppressor prescription.
