Abstract
The invention relates to a fuel for a boiler, specifically to a composite carbon slurry with desulphurizing and denitrating functions. To overcome technical problems in the prior art, the invention provides a desulphurizing and denitrating composite carbon slurry which has desulphurizing and denitrating functions and can improve desulphurization and denitration effects. According to a technical scheme in the invention, the desulphurizing and denitrating composite carbon slurry comprises the following components by weight: 65% of a coal base, 29 to 32% of water, 0.3 to 0.5% of a dispersant, 0.1 to 0.3% of a stabilizing agent, 2 to 3% of a desulphurization agent and 1% of a denitration agent The invention has the following beneficial effects: during combustion, the composite carbon slurry realizes desulphurization and denitration effects; extra denitration procedure is not needed; and the desulphurization and denitration effects are obviously better than those in the prior art.
Description
Technical field
The present invention relates to the fuel that a kind of boiler uses, specifically a kind of composite carbon slurry with desulphurization denitration function.
Background technology
Composite carbon slurry is that a kind of coal-based, the water of 29%, functional agent of 6% by 65% forms; Can high performance clean burning, the compound fluid fuel of decreasing pollution thing discharge.Carbon back in coal is through broken, and grinding, under the effect of dispersion agent, forms the fluid of solid liquid phase with water; Under the effect of stablizer, delay the sedimentation speed of solid phase particles; Namely this solid-liquid homogeneous phase mixture slurry that carbon granule and water are formed under dispersion agent and stablizer acting in conjunction is the parent of composite carbon slurry.Add desulfurization or denitration functional agent on this basis and be desulfurization or denitration composite carbon slurry, or add two kinds of functional agents simultaneously and be namely called that desulphurization denitration composite carbon is starched.
Denitrating technique of the prior art is higher to temperature of reaction control overflow, time namely only within the scope of 900 ~ 1100 DEG C, just can reach object that is efficient and non-secondary pollution, because flue gas cooling rate in discharge process is fast, makes denitration rate lower, be only 30 ~ 50%.In prior art, desulfurization technology for add sweetening agent in solid coal cinder, but due to coal cinder water content in combustion processes low, make sweetening agent inefficiency, sweetening effectiveness is undesirable.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of desulphurization denitration composite carbon slurry, carbon is starched and has desulfurization and denitration function, improve desulfurization off sulfide effect.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: desulphurization denitration composite carbon is starched, comprise coal-based, water, dispersion agent, stablizer, sweetening agent, denitrfying agent, wherein each component accounts for the weight percent of total amount is coal-based 65% respectively, water 29%-32%, dispersion agent 3 ‰-5 ‰, stablizer 1 ‰-3 ‰, sweetening agent 2%-3%, denitrfying agent 1%.
Optimally, described sweetening agent is one or both in calcium carbonate, Calcium hydrogen carbonate.
Optimally, described denitrfying agent is one or both in urea, ammoniacal liquor.
Optimally, described dispersion agent is one or both in naphthalenesulfonate, sulfonated lignin.
Optimally, described stablizer is one or both in Xylo-Mucine, ferrous sulfate.
Optimally, described sweetening agent is for add in process of production.The sulfurous gas of generation is converted into calcium sulfite and is precipitated out by moisture contained by utilizing composite carbon to starch during burning in a large number.
Optimally, described denitrfying agent is add before using after manufacture.
Beneficial effect of the present invention is: this composite carbon slurry realizes the effect of desulphurization denitration in burning, and without the need to additionally carrying out denitration operation, and desulfurization off sulfide effect is obviously better than prior art.
