Description

A kind of boiler fired coal additive and preparation method thereof and using method
Technical field
The present invention relates to a kind of additive for fire coal, particularly relate to that there is combustion-supporting, the additive for fire coal of desulphurization and denitration and system thereof Preparation Method and using method.
Background technology
At present, combustion-supporting type additive for fire coal, the following material of general employing is as component: 1) alkali metal, alkaline-earth metal and mistake Cross metal-oxide, such as magnesium oxide, calcium oxide etc.；2) bases of alkali metal, alkaline-earth metal and transition metal or salt, such as nitric acid Salt, carbonate, chlorate, villaumite and some acylate etc.；3) oxidant, such as permanganate, potassium nitrate etc..
Such as: Chinese patent CN101269339A discloses a kind of coal combustion catalyst, by potassium salt, technical grade sodium chloride, life Calx, alum clay, rare earth oxide or rare earth chloride, iron sesquioxide composition, described potassium salt is nitrate or carbonate.Chinese patent CN101220313A discloses a kind of coal combustion catalyst, by oxide, halogenide, oxyhydroxide, organo-metallic compound, alkali The salt composition of metal；Described oxide is one or more of alkali metal, alkaline-earth metal and transition metal oxide；Described halogen Compound is NaX, CaX2, HgX, wherein X is fluorine, chlorine, bromine, iodine；Described transition metal oxide is MnO etc.；Described iodine metal Salt be KMnO4、Na2CO3、K2CO3。
The shortcoming of existing combustion-supporting type additive for fire coal is as follows: 1) coal combustion equipment is easily caused corrosion by halogenide, particularly halogen Chloride ion in compound additive is easily formed HC in coal-fired atmosphere1Gas, to boiler water wall, superheater, reheater piping Cause corrosion.2) carbonate such as Na2CO3、K2CO3At high temperature decompose and produce greenhouse gases CO2, add the pollution to environment. 3) denitration effect is poor.
In view of above-mentioned deficiency, invention a kind of combustion-supporting, desulfurization off sulfide effect good, little to coal combustion equipment corrosivity, realize refuse Innoxious, low cost, safe and environment-friendly additive for fire coal have been to be badly in need of.
Summary of the invention
The technical issues that need to address of the present invention are that the defect overcoming prior art, it is provided that a kind of reduce lighting of coal Temperature and lime-ash carbon content rate, improve burning of coal rate, reduce that corrosion coal combustion equipment, desulfurization off sulfide effect be good, dust contains in flue gas Amount less, the additive for fire coal of low cost and preparation method thereof and using method.
The present invention uses the technical scheme to be: a kind of boiler fired coal additive, and it includes following weight portion content component, CuO: 10-18 part, NH4VO3: 15-25 part, Na2B4O7·10H2O:15-20 part, Al powder: 10-20 part, H2O2: 15-20 part, chromium slag: 15- 25 parts, NaOH:5-10 part, TEA(triethanolamine): 8-13 part, rare earth oxide: 2-5 part.
In such scheme, it is preferable that also include glycine betaine 5-10 part.Preferably, MnO:5-10 part and Fe are also included2O3: 2- 6 parts.Wherein it is preferred to, rare earth oxide is preferably CeO2Or La2O3In one, it is highly preferred that press CeO2/La2O3Mass ratio is The mixed rare earth oxide of 3.5:1-3.75:1.
The present invention also provides for the preparation method of a kind of boiler fired coal additive, and step is as follows: (1), according to above-mentioned weight portion Weigh each component；By CuO, NH4VO3It is milled to 40-70 micron raw material a with rare earth oxide；By Al powder with chromium ground-slag is broken, sieve and obtain Obtain the particulate material b that particle diameter is 200-250 mesh；By Na2B4O7·10H2O is dissolved in 100 parts of water formation compound A, exists subsequently In described compound A, add described NaOH at 60-80 DEG C successively and triethanolamine forms compound B, be eventually adding described H2O2 Prepare raw material c；Step (2) by described raw material a, b, c and other material glycine betaine or/and MnO and Fe2O3Mix homogeneously prepares.
Present invention also offers the using method of boiler fired coal additive: the additive of above-mentioned preparation is pressed coal-fired matter by (one) The 0.15-0.5wt% of amount adds to described fire coal.(2) additive of aforementioned preparation is pressed solute/solution quality than for 1:9 Proportioning be configured to aqueous solution, bulk fire coal be impregnated in described aqueous solution, wherein, solute and coal-fired mass ratio in solution Example is 0.15-0.5:1.
In additive for fire coal of the present invention: chromium slag is the waste residue produced in bichromate production process, containing a large amount of water solublity Cr6+Compound, it can promote burning of coal, be catalyzed NOxTransfer N to2And catalysis SO2Transfer to for SO3, prevent and treat boiler coke, Cr6+ Compound is reduced avirulent trivalent chromium compound, such as Cr2O3, lower offal treatment cost and environmental pollution.
Al powder promotes coal to ignite rapidly, reduces the ignition temperature of coal, forms aluminium oxide, alumina catalyzation SO at 500 DEG C2 Reacting with CO, this reaction is exothermic reaction, reduces SO in flue gas2With CO content, improve ignition temperature.
H in above-mentioned additive2O2O can be resolved into when 350 DEG C2And H2O, O2Promote coal combustion, at high temperature decompose H2O Yu C reaction response, the trans-utilization improving carbon reduces lime-ash carbon content rate.
Rare earth oxide is oxygen delivery agent and coal combustion catalyst, and it can promote C cracking reaction, the dehydrogenative condensation of suppression coal. Applicant have surprisingly discovered that: when rare earth oxide uses CeO2/La2O3When mass ratio is the mixed rare earth oxide of 3.5:1-3.75:1, The combustion-supporting desulfurization denitration effect of additive is particularly good.
Triethanolamine, i.e. TEA, it as dispersant and penetrating agent, promotes that other component is dispersed to coal with glycine betaine In charcoal micropore, strengthen combustion-supporting, catalytic effect.
At about 220 DEG C NH4VO3Decompose, the V of generation2O5Having higher activity, vanadium is similar with copper, for can Variable valency metal, the transmission of the oxygen in energy catalytic oxide, promote coal combustion；Its NH4 +And decompose the NH generated3There is catalysis to make to coal With；NH under Cr oxide catalyst effect3With the NO in combustion processxSuch as NO and NO2There is strongly exothermic redox reaction, subtract Few NOxDischarge.
Na2B4O7·10H2O can eliminate the cinder in coal combustion equipment burner hearth, reduces equipment corrosion.
The beneficial effects of the present invention is: (1) additive raw material low cost, promote coal combustion desulphurization denitration realize simultaneously Hazardous waste is innoxious.(2) additive does not contains chloride ion compound, caking risk corrosion-free to coal combustion equipment.(3) add Agent not carbonate containing, nitrate, reduce NOxAnd CO2Discharge, environmental protection.(4), lime-ash carbon content rate is low, burning of coal rate is high, in flue gas Dust content is few.
