Abstract
The production process of smoke-eliminating, dust removing and energy saving combustion improver includes a) crushing, grinding and mixing potassium chloride, magnesium chloride and Fe2O3, setting the mixture inside a reactor and mixing with water for reaction; b) crushing ammonium nitrite and setting inside one other reactor and mixing with water for reaction the product of the fore step; c) mixing crushed coarse whiting, nitric acid and water to produce calcium nitrate; mixing calcium nitrate with the product of step b) for reaction, stoving, adding RE, quartz, barite and carbonate for reaction, and adding kaolin to reaction to obtain the combustion improver. The combustion improver is used in coal combustion to perform the functions of catalysis, releasing heat, fixing sulfur and lowering environmental pollution.
Description
Technical field:
The invention belongs to chemical field, particularly the fuel in the coal-mining industry is the manufacture method of a kind of smoke elimination, dedusting, combustion energy-saving combustion adjuvant specifically.
Background technology:
China is one and uses coal big country, nearly more than 40 ten thousand boilers, annual 300000000 tons in the coal that consumes, more than 11 ten thousand of Industrial Stoves, year is consumed more than 200,000,000 ton in coal, and more than 200,000,000 ton in civilian coal is because equipment and technology is outmoded, boiler efficiency is low, energy consumption is big, and exhaust gas emission exceeds standard, and air environmental pollution is serious, at present, for energy consumption that reduces coal firing boiler and the influence that reduces the coal firing boiler environmental pollution, need transform coal firing boiler, change and use coal-fired be use fuel oil or combustion gas, but need to drop into huge fund, and also need the working cost of great number after transforming, in the prior art, in order to improve coal-fired efficiency of combustion, usually use ignition dope, described ignition dope comprises potassium permanganate, sodium salt, ferric oxide and Manganse Dioxide.
Summary of the invention:
Technical problem to be solved by this invention is: in the prior art, in order to improve coal-fired efficiency of combustion, usually use ignition dope, described ignition dope comprises potassium permanganate, sodium salt, ferric oxide, Manganse Dioxide, but potassium permanganate is a kind of strong oxidizer, and security is not high, cost is big, and contain a large amount of sodium salts, and the easy coking of the ignition dope of ferric oxide and Manganse Dioxide, combustion-supporting effect is not good, can cause secondary pollution simultaneously, the present invention provides a kind of smoke elimination for the technical scheme that above-mentioned technical problem adopted that solves in the prior art, dedusting, the manufacture method of combustion energy-saving combustion adjuvant, wherein, the manufacture method of described ignition dope comprises the steps:
A) with 4.0-6.0 part potassium chloride, 3.0-4.0 part magnesium chloride, 4.5-5.5 part Fe
2O
3After fragmentation, the fine grinding, mix, be placed in the reaction pot, add certain water, stirring reaction 8-12 hour;
B) 6.0-8.0 part nitramine is pulverized, be placed in another reactor, add entry, stirring reaction 8-12 hour, a) last reactant is added mixing then, stirring reaction;
C) with after the pulverizing of 25-30 part coarse whiting, be placed in the reaction pot, add 0.5-1.0 part nitric acid and add water, stir, mixing is after the dehydration, generate calcium nitrate, then with b) reactant that obtains of step stirs and evenly mixs, after the reaction, oven dry, add then the quartzy barite carbonate of 24-30 part rare earth, after the reaction, add 27-30 part kaolin ore mixing, reaction can obtain industrial operable combustion adjuvant (above-described umber is weight portion) again.In the manufacture method of combustion adjuvant of the present invention, the quartzy barite carbonate of described rare earth comprises La2O
