Abstract

The invention relates to a special-effect coal-saving composite additive. The invention belongs to the technical fields of energy saving, environmental protection, and new energy. According to the invention, various compounds and minerals with a certain ratio are processed into composite powder with a fineness of 200-300 meshes; with a proportion of 0.1-0.3%, the powder is directly uniformly mixed into coal with a water content of 8-10%; and the mixture can be applied in various industries, power industries, agricultural industries, pit furnaces, and domestic stoves. With relayed chemical, physical, and ion exchange composite reactions of the additive components, functions such as catalyzing, thermal insulation, combustion-supporting, smoke abatement, and the like are provided. Fired coal forms a stable inner and outer flame high-temperature combustion state. Therefore, combustible materials in coal, and carbon monoxide CO gas and sulfur-containing flue gas SO2 produced during combustion are forced to combust. Heat is increased, and emission is reduced. As a result of experiments, with a moderate dose of the formula, a coal saving rate can be higher than 20%, a smoke degree can be reduced by 30-45%, a sulfur capturing rate reaches 65-90%, and slag carbon content is reduced by 45-55%. When the scheme provided by the invention is implemented, special effects such as fast fire, high and stable furnace inner and outer flame temperature, sufficient combustion, high heat production value, and less smoke dust. Also, functions of coke removing and dust removing are achieved. Therefore, purposes of energy saving, emission reducing, and environment protecting are achieve.

Description

The special efficacy composite additive of economizing on coal

Technical field: the present invention relates to a kind of special efficacy composite additive of economizing on coal.Belong to energy-saving and emission-reduction, protection of the environment, technical field of new energies.

Background technology: along with the development of world economy, the energy and environmental problem become increasingly conspicuous, and Chinese Government pays much attention to address this problem, develop the economy, save energy is as fundamental state policy.The energy-conserving and emission-cutting technology scheme of constantly updating is to reduce mining deposits exploitation, Developing Circulation Economy, the effective way of preserving the ecological environment.

Summary of the invention: content of the present invention provides a kind of special efficacy composite additive of economizing on coal, it is processed into fineness by a certain percentage with multiple compounds and mineral is 200-300 purpose compound powder, ratio Direct Uniform with 1-3 ‰ is mixed in the coal of water content 8-10%, for the stoves such as all types of industries, electric power, agricultural cellar for storing things and life cooking stove; Make coal in combustion processes with additive in various compounds, mineral recur the chemistry of strong oxidation, catalysis, ion-exchange, the physics complex reaction, play combustion-supporting, economize on coal, the special efficacy of desulfurization, smoke elimination, decoking, deashing.

Composition of raw materials and Action Specification: the invention will be further described below in conjunction with the various material names of prescription, molecular formula, characteristic, effect, ratio of components and embodiment.

Combustion supporting catalytic smoke suppressor ferrocene C10H10Fe, fusing point 173-176 ℃, temperature is not decomposed in 400 ℃, a kind of good combustion-supporting, catalysis smoke suppressor, thermostability with height, in many chemical reactions and combustion reactions, show the performance of catalytic activity and energy-saving and smoke-removing: but 0.1% fuel-economizing 10-14% in diesel oil, added, power improves 10%, and the 30-70% that can eliminate smoke; Combustion speed propelling agent as rocket propellant in space industry uses; Add 0.2% in coal fuel is descended more than 20%, smoke intensity 30-45% can descend simultaneously; Have catalysis, combustion-supporting, energy-conservation, to eliminate smoke and impel carbon monoxide CO gas reforming be the effect of carbonic acid gas CO2 gas.Ratio of components is 35-40%.

1300 ℃ of bulk sweetening agent Calcium Fluoride (Fluorspan) CaF2, fusing points, it uses as fusing assistant in Iron And Steel Industry, can increase the flowability of slag, impels coal abundant burning in burner hearth not lump; Share the effect with desulfurization with calcium oxide CaO.Ratio of components is 8-10%.

270 ℃ of oxidation catalysis ignition dope potassium permanganate KMnO4, fusing points, when reaching 270 ℃, temperature just begins to decompose that to emit oxygen O2 combustion-supporting, the Manganse Dioxide MnO2 that produces after it decomposes has catalysis Potcrate KCIO3 and decomposes progressively when 400 ℃ of temperature that to emit oxygen O2 combustion-supporting, has the effect of oxidation sulfur dioxide in flue gas SO2 with oxonium ion (H3O+) reaction.Ratio of components is 3-4%.

Oxidation ignition dope Potcrate KCIO3,356 ℃ of fusing points, its stability is higher than potassium permanganate KMnO4, under the catalysis of potassium permanganate KMnO4, when temperature rises to 400 ℃, Potcrate KCIO3 begins to decompose that to emit oxygen O2 combustion-supporting, emits all oxygen O2 when temperature rises to 600 ℃, has combustion-supporting effect.Ratio of components is 12-15%.

610 ℃ of strong oxidation ignition dope potassium perchlorate KCIO4, fusing points, its stability is higher than Potcrate KCIO3, begins to decompose when temperature rises to 610 ℃ to emit oxygen O2 combustion-supporting effect is arranged.Ratio of components is 5-8%.

Combustion-supporting stablizer sodium chloride NaCI, 810 ℃ of fusing points, it not only has combustion-supporting effect, can play stable effect to each chemical reaction again.Ratio of components is 8-10%.

Gu 851 ℃ of dirty agent sodium carbonate Na2CO3, fusing points fall in sulphur, the coal surfactivity is increased, inflammable and play solid sulphur, dirty effect is fallen.Ratio of components is 2-3%.

2580 ℃ of sweetening agent calcium oxide CaO, fusing points use separately or share the effect that all has desulfurization with Calcium Fluoride (Fluorspan) CaF2.Ratio of components is 8-10%.

Embodiment: owing to adopt such scheme, 200 orders-300 order composite additive the total amount that the is processed into fineness ratio Direct Uniform in 1-3 ‰ is mixed in the coal that water content is 8-10%, for all types of industries, electric power, the stoves such as agricultural cellar for storing things and life cooking stove use, because the chemistry of formula is held in both hands in relay between each additive component, physics, the catalysis that the ion-exchange complex reaction brings up, insulation, combustion-supporting, the effects such as smoke elimination, make coal-fired freeze profile become one stable in, flame envelope high-temp combustion state, force the carbon monoxide CO gas and the sulfur-containing smoke gas SO2 burning that produce in the combustible species and combustion processes in the coal, the gain of heat reduces discharging, but experiment shows the median dose with prescription and reaches more than 20% with regard to envoy's combustion rate, smoke intensity decline 30-45%, sulfur-fixing rate reaches 65-90%, and boiler slag carbon content reduces 45-55%.Implement this programme and have on fire soon, in the burner hearth, the flame envelope temperature is high and stablize, and sufficient combustion, thermal value is large, flue dust is few, the special efficacy of decoking, deashing, reaches save energy, reduces and discharges, the purpose of protection of the environment.
