Description

A kind of coal combustion clean catalysis agent
Technical field
The present invention relates to coal combustion technology fields, and in particular to a kind of coal combustion clean catalysis agent.
Background technique
The coal combustion efficiency of the prior art, generally below 85%, while the process burnt can also generate sulfur dioxide, nitrogen oxygenThe problem of compound, smoke contamination.Burning of coal efficiency is improved, coal resource can be effectively saved, it is common to promote coal combustion efficiencyMethod be exactly to allow coal to carry out oxygen-enriched combusting, and titanium dioxide will certainly be generated because of the presence of objective factor, in coal combustion processSulphur and nitrogen oxides, traditional method are exactly that adsorbent is used to adsorb and filter sulfur dioxide and nitrogen oxides, are preventedIt enters atmosphere pollution air, and the amount of the sulfur dioxide and nitrogen oxides that generate in coal combustion process is very big, this is just needed greatlyThe adsorbent of amount.Either oxygen-enriched combusting or adsorbent absorption tail gas require corresponding equipment to carry out, to burningIt is a complicated job that system, which is transformed or adds other equipment, virtually also will increase production cost, and this sideThe heat that carried in sulfur dioxide and nitrogen oxides will not be used for method, cannot improve the utilization rate of thermal energy.Thus,Best bet is while promoting burning, and can to reduce pollution using a kind of combustion catalyst.And existing catalyst,It can not be suitable for 1000 tons or more of large-sized boiler, and temperature is once excessively high, the stability of catalyst will sharply decline.
Summary of the invention
It is an object of the invention to: in view of the above-mentioned problems, providing a kind of coal combustion clean catalysis agent.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of coal combustion clean catalysis agent, including following component: solvent, oxygen-containing free radical component, infiltration class component, catalysis are splitSolve class component, menu noodles component, metal organic chelate;
The solvent is one or more of kerosene, liquefied coal coil, tar, Emulsifier EL-60;
The infiltration class group is divided into the mixing of polyoxyethylene ether, thiosulfonic acid, laurylene, dimethyl sulfoxide CAB health oleamide propylObject;
In the catalytic pyrolysis class component, catalyst active component is the base metal of VIB and/or VIII group, catalyst carrierFor amorphous oxide or silicate;
The menu noodles component is the mixture of Octylphenol polyoxyethylene ether, organic ammonium salt, alcohols.
Further, the oxygen-containing free radical group is divided into the mixing of sodium nitrite, potassium nitrite, sodium nitrate, potassium nitrateObject, sodium nitrite, potassium nitrite, sodium nitrate, potassium nitrate mass ratio be 4:4:2:2.
Further, in the infiltration class component, polyoxyethylene ether, thiosulfonic acid, laurylene, dimethyl sulfoxide, CAB health oilThe mass ratio of amido propyl is 2:1:1:1:2.
Further, in the menu noodles component, the quality of Octylphenol polyoxyethylene ether, organic ammonium salt, alcoholsThan for 2:1:8.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1. coal combustion clean catalysis agent of the invention, catalytic pyrolysis class component can promote coal coal macromolecular chain in combustionCracking, oxygen-containing free radical component at high temperature, discharges a large amount of oxygen, accelerates the power for improving coal combustion, pass through menuNoodles component and metal organic chelate make the coal very high voidage of coal cinder holding and specific surface area in combustion, make heatAmount spreads equal spoon, guarantees the activity of alkaline earth oxide, to reach dedusting, desulphurization denitration and energy-efficient purpose;And solventWith infiltration class component, effectively catalyst can be allowed to penetrate into inside coal seam, dissolve various components, promote the combustion inside coal seamBurn, by improve coal burn rate, make burning it is more abundant, reduce boiler air coefficient of excess, aggravate furnace in turbulence simultaneouslyPromote furnace heat uniformly to spread in time, improves capacity usage ratio, and then achieve the purpose that Synergistic and energy-saving.
2. coal combustion clean catalysis agent of the invention, can optimize ash content surface property in coal, forming it into has high reactionThe surface of property, and then so that furnace sulphur oxide, reaction of nitrogen oxides is reacted forming salt with metal organic chelate to greatest extentClass compound, reach desulphurization denitration effect, meanwhile, the efficient full combustion of coal, formed salt compounds after can also reduce dust,The discharge of carbon monoxide and carbon dioxide;The generation of the burnt dirt of coal-burning boiler can also be reduced and devoke scale removal, improve the work of burnerMake situation, improve production safety, reduces its operation and maintenance cost.
Specific embodiment
A kind of coal combustion clean catalysis agent, including following component: solvent, infiltration class component, is urged at oxygen-containing free radical componentChange cracking class component, menu noodles component, metal organic chelate;
The solvent is one or more of kerosene, liquefied coal coil, tar, Emulsifier EL-60;
The infiltration class group is divided into the mixing of polyoxyethylene ether, thiosulfonic acid, laurylene, dimethyl sulfoxide CAB health oleamide propylObject;
In the catalytic pyrolysis class component, catalyst active component is the base metal of VIB and/or VIII group, catalyst carrierFor amorphous oxide or silicate;
The menu noodles component is the mixture of Octylphenol polyoxyethylene ether, organic ammonium salt, alcohols.
Preferably, the oxygen-containing free radical group is divided into the mixture of sodium nitrite, potassium nitrite, sodium nitrate, potassium nitrate,Sodium nitrite, potassium nitrite, sodium nitrate, potassium nitrate mass ratio be 4:4:2:2;
In the infiltration class component, the matter of polyoxyethylene ether, thiosulfonic acid, laurylene, dimethyl sulfoxide, CAB health oleamide propylAmount is than being 2:1:1:1:2;
In the menu noodles component, Octylphenol polyoxyethylene ether, organic ammonium salt, alcohols mass ratio be 2:1:8.
Above description is the detailed description for the present invention preferably possible embodiments, but embodiment is not limited to this hairBright patent claim, it is all the present invention suggested by technical spirit under completed same changes or modifications change, should all belong toIn the covered the scope of the patents of the present invention.
