Abstract
The high efficiency coal-saving desulfurizer for various coal burning boilers, industrial furnaces and kilns and domestic furnaces is compounded with the first material capable of creating high activity chloride and the second material through heat treatment at temperature over 40 deg.c and capable of producing metal oxide. When used, the high efficiency coal-saving desulfurizer in the amount of 0.1-0.5 wt% of coal is added into coal for burning together with coal, and can decompose coal fast, activate coal fully and burn reasonably, so as to raise heat efficiency of boiler, reduce exhausted smoke and dust, SO2, CO and other harmful gas and thus reach the aims of saving coal and reducing pollution.
Description
The present invention relates to a kind of high efficiency coal saving sweetening agent that is used for various coal firing boilers, Industrial Stoves and Civil energy-saving cooking stove.
China is that producing coal all is maximum countries with burning coal in the world.In China's energy structure, based on coal, coal is first energy., in burning of coal utilizes, the ubiquity two large problems: the one, burning of coal is insufficient, and is unreasonable, and coal consumption is big, and thermo-efficiency is low, the coal resources serious waste; The 2nd, coal is a kind of uncleanly natural calculus-dissolving fuel, and combustion technology falls behind in addition, causes coal to produce multiple obnoxious flavour and materials such as volume of smoke, sulfurous gas, carbon monoxide, atmosphere pollution when burning.
To this, the Chinese government and relevant department and numerous scientific workers pay much attention to, economize on coal the consumption reduction and reduce coal-fired noxious emission a large amount of technology development works done in topsoil, obtained some effects, but produce little effect, its economic benefit, environmental benefit, social benefit are all undesirable.
As everyone knows, the ultimate analysis of coal shows that coal is that burning of coal is these complex compounds, the physics of mixture complexity, chemical reaction process by multiple elementary composition combustible and non-flammable complex materials such as carbon, hydrogen, oxygen, nitrogen, sulphur, phosphorus.When past people utilizes coal to obtain heat energy, it being burnt in air, still can not reasonably utilize with scientifically burning, is to cause both to waste coal resources, again one of reason of major polluting atmosphere environment.
Purpose of the present invention is exactly the structure of matter according to the complexity of coal, the physics of the complexity that takes place during burning, chemical transformation, and thermodynamic principles, and boiler, kiln practical operation situation provide a kind of high efficiency coal saving sweetening agent.In coal, add a small amount of this high efficiency coal saving sweetening agent, go into the stove burning together with coal, make coal in a series of physics, chemical transformation such as catalysis, activation, gasification, complexing, decomposition, displacement, chemical combination, energy evolution, fully rationally burning, improve thermo-efficiency, save coal; Simultaneously, suppress and reduce the generation and the discharging of multiple obnoxious flavoures such as flue dust, sulfurous gas, carbon monoxide, blackness of exhaustion, the protection atmospheric environment; Can also eliminate simultaneously the burnt dirt of burner hearth, improve heat conductivility, prolonged boiler work-ing life.
For achieving the above object, high efficiency coal saving sweetening agent of the present invention is formed first kind raw material by one or more materials that can generate high activity chloride; By forming the second class raw material through heat-treated more than 40 degrees centigrade and one or more materials that can generate metal oxide, again with first kind raw material and the second class raw material through processing composite forming.Its shared weight percent: first kind raw material 10-90%, the second class raw material 90-10%.
Wherein, first kind raw material is made up of in Repone K, sodium-chlor, calcium chloride, magnesium chloride, Potcrate, sodium chlorate, calcium chlorate, magnesium chlorate, potassium perchlorate, sodium perchlorate, calcium perchlorate, the magnesium perchlorate one or more.
The second class raw material is by forming through in the potassium oxide of heat-treated more than 40 degrees centigrade, sodium oxide, calcium oxide, magnesium oxide, aluminum oxide, ferric oxide, manganese oxide, chromic oxide, vanadium oxide, potassium hydroxide, sodium hydroxide, calcium hydroxide, magnesium hydroxide, aluminium hydroxide, ironic hydroxide, salt of wormwood, yellow soda ash, lime carbonate, magnesiumcarbonate, manganous carbonate, potassium manganate, sodium manganate, potassium permanganate, sodium permanganate, saltpetre, SODIUMNITRATE, nitrocalcite, the magnesium nitrate one or more.
The course of processing: each material in the first kind raw material is crushed to the 40-60 order, with each material in the second class raw material respectively under the 40-120 degree celsius temperature, after thermal treatment 8-36 hour, naturally cool to room temperature, thereafter separated pulverizing is to the 40-60 order, first kind raw material and the second class raw material is mixed together to stir again.
The present invention is further described below in conjunction with embodiment:
Embodiment 1:
