Abstract

The invention relates to a coal detergent, it is added chemical adjuvant by the compound and synthesized the reagent that can remove the harmful substance in the fire coal, the molecular sieve containing metallic element, it is a magnesium, calcium, silicon, aluminium type molecular sieve, the finished product is fine graininess, the consumption, can be regarded as additive to process the raw coal or regarded as the dip-coating agent to process the briquette coal, the fire coal supplies after the invention is processed are left naturally and used after 24 hours under the dry condition, the use temperature is 950 duC, the advantage of the invention is that the raw materials are easy to get, process simple, easy to use, cheap, process the supplies and carry on at room temperature, can reduce the discharge of the harmful substance in the fire coal effectively, the purification rate reaches 90%.

Description

Coal burning agent for reducing smoke or undesirable deposits
The present invention relates to the purification techniques of objectionable impurities in a kind of fire coal, particularly a kind of coal burning agent for reducing smoke or undesirable.
At present, purification techniques development about objectionable impurities in the fire coal is very fast, especially aspect industrial furnace, use some refining plants, use some purifying methods to obtain very big progress, as in fire coal, adding compound oxidation magnesium (being commonly called as rhombspar), the widespread use of the certain methods of clay and citrate of lime, but these are to the sulfide in the fire coal, the tangible method of nitride decontamination effect improving, no matter be to adopt device also to be to use reagent, its comprehensive purifying effect is still unsatisfactory, because objectionable impurities just is discharged into outside the Working environment, still remain in the air, its influence still exists.And the facility investment of using is big, and reagent expense height is not easy to apply on a large scale, particularly applying aspect civil.
The objective of the invention is,, propose a kind of coal burning agent for reducing smoke or undesirable at above-mentioned the deficiencies in the prior art.
Technical solution of the present invention is, add the synthetic reagent that can remove objectionable impurities sulphur, nitrogen, cyanogen, fluorine cpd and carbon monoxide of chemical assistant by compound, it is characterized in that, this reagent is the sticking agent that contains the metallic element molecular sieve, by multiple natural inorganic mineral and organic acid is compound makes, perhaps add acid or the making of bases chemical assistant by compound, its finished product is a fine particulate.Using method of the present invention is to handle coal-fired material at normal temperature condition, makes additive, and the dip-coating agent is done in per kilogram additive and the fusion of 100-120 kilogram raw coal, the dip-coating agent that the hot water of per kilogram raw material and 5 kilograms 〉=70 ℃ is modulated thick pulpous state.Dip-coating 80-100 kilogram moulded coal, the entire treatment process is carried out under normal temperature condition, and coal-fired material after treatment leaves standstill naturally under drying conditions after 24 hours and to use, in 950 ℃ of the use temperatures.The present invention is applicable to the coal-fired material of sulfur-bearing≤3%.The invention belongs to a kind of magnesium, calcium, silicon, aluminium type molecular sieve.According to coal gas, solid phase physical and chemical principle, make the molecular adsorption in the molecular sieve of the metallic element that the gas molecule particulate of the objectionable impurities that discharges in the fire coal can contain with the present invention under the different temperature difference, conversion is gas phase, solid state reaction generates unhydrolyzed binary compound, get rid of with the waste residue behind the fired coal combustion, reduced emission of harmful substances amounts such as sulphur, cyanogen, fluorine, nitrogen compound and carbon monoxide effectively, reduced it for the erosion of human body and the pollution that causes to environment.
The invention has the advantages that, constitute raw material of the present invention and be easy to get that processing is simple, easy to use, cheap, handling coal-fired material is to carry out at normal temperatures.Both can handle with coal, can handle with coal commercial coal stove again Industrial Boiler, remove with the set fire coal in objectionable impurities, decontamination and deodorant, purification efficiency is up to 90%.Processing of the present invention and application process are all pollution-free, and its comprehensive benefit is better than, and known " single alkali " reaches " two alkali ".It is good to burn slag forming through the fire coal after the present invention's processing, the hardness height, its set material forms integument (being responding layer) with the burning slag, not only purified environment but also improved coal-fired heat utilization efficiency, effect is fairly obvious, also for comprehensive regulation environmental pollution with eliminate objectionable impurities in the fire coal and provide a kind of effective few product and method of spending to the erosion of human body.
Now, embodiments of the invention are described:
Preparing quick lime, two kinds of compounds of calcium oxide with unslaked lime weight ratio 1%, they are mixed, levigate to 200 orders, as carrier, in carrier, add chemical assistant, wherein add the aluminium sesquioxide of vehicle weight 1%, 1.5% sodium silicoaluminate, 0.5% ferric oxide, 1% magnesiumcarbonate, 1% ethanol, 0.4% citric acid, 0.2% second two ammoniums, 1% acetic acid, even with carrier mix in mixing machine, duration of mixing 2 hours, the roasting 2 hours under 350 ℃ of temperature condition of material evenly, make the sticking agent that contains the metallic element molecular sieve, get 40 order screen underflows through screening and use as finished product.Using method of the present invention is, make additive, per kilogram reagent can be handled 100-120 kilogram raw coal, does the dip-coating agent, per kilogram reagent becomes the dip-coating agent of thick pulpous state with 5 kilograms 〉=70 ℃ hot water hybrid modulation, can dip-coating processing 80-100 kilogram moulded coal (for example honeycomb briquette).Using the present invention to handle coal-fired entire treatment process carries out at normal temperatures.The present invention is applicable to the fire coal of sulfur-bearing≤3% scope.Coal-fired material after the present invention handles needs leave standstill naturally under the drying conditions to re-use after (promptly 1 round the clock) in 24 hours, in 950 ℃ of the use temperatures.
Use magnesian lime, ground dolomite and magnesium cement to do carrier, interpolation chemical assistant salt, caustic soda or interpolation soda ash, vinegar are made the coal burning agent for reducing smoke or undesirable of the molecular sieve that contains metallic element also can use the method processing treatment fire coal that the present invention proposes, and its effect is fine.
