In the concentration emulsifier fuel feedstocks, add concentration emulsifier fuel feedstocks 0.7-2.5 water doubly then, generate emulsion fuel through stirring.The water ratio of this fuel is 41-70% when using, the propulsion source internal combustion that emulsion fuel is acted as a fuel and is put into boiler, oil engine or other combustion of liquid.
In the prior art, water ratio is at least 41-% in order to reduce the flue dust that waste gas is arranged that produces in the burning and the generation of oxynitrides, can realize by improving the fuel oil water ratio, but improving the fuel oil water ratio will cause the burned flame temperature to reduce, the evaporation of moisture simultaneously reduces the thermo-efficiency of latent heat and fuel oil, so be difficult to use emulsion fuel in efficient boiler, the content of moisture also was restricted during plain cylindrical furnace was fuel used.
The present invention is based on the design of emulsive principle science.The ultimate principle of its foundation is as follows:
Emulsion is meant that the liquid particle in the liquid becomes colloidal (colloid) or becomes thick particle shape to be dispersed in the lactous liquid.The material of colloid (colloid) shape can't see with ordinary optical microscope, but the colloidal particle is more bigger than atom, molecule.When colloid is dispersion state, be called colloidal state, its dispersion system is called colloid, and dispersed particle is colloidal particle.The general 1-500nm of the diameter range of colloidal particle contains 10
3-10
9Atom.Common colloid is that liquid is done to disperse medium, be also referred to as colloidal sol or colloidal solution (colloidalsolution).
The colloid that has positive charge is called positive colloid (positive colloid), has negative colloid of being called of negative charge (negative colloid).Negative colloid is in the majority in nature.Polymer is called as molecular colloid because of himself having the character of colloidal particle.Polymer electrolyte also has most fixedly electronics, can be used to make colloidal particle, is also referred to as polyion (polyion) or big electronics (macroion).This is the state of matter in conceptive expression.
Oil and water can generate emulsion through mixing in the short period of time, but very fast separation forms oil and water is two-layer.Obtain stable emulsion, just need the drop in the liquid be stablized with the emulsifying agent surface protective film that tabulates.The emulsion that water and oil form generally has two kinds, and a kind of is oil-in-water shape (O/w) type, and another kind is water-in-oil-type (W/O), by selecting to use different emulsifying agents, can obtain two types emulsion respectively.
Emulsifying agent is Dang Shui and oil when carrying out emulsification, is used to make the material of emulsion-stabilizing.The effect of emulsifying agent be water or oily sorption on the interface, interfacial tension is descended, so that obtain the interface protective film.For example all contain mixture in soap, the washing powder as polymer substances such as the anion surfactant of emulsifying agent and protein.
The present invention is dissolved in anion surfactant in the distilled water, stir and produce the colloidal emulsifying agent down, with oil is that liquid fuel joins in the aqueous solution of emulsifying agent, stir and form colloidal concentration emulsifier fuel feedstocks down, what this raw material formed is oil-in-water emulsion, possess hydrophilic property, under stirring and bubble effect, it is big that its volume becomes, and makes the contact area of moisture that increase be arranged again, therefore can add to concentrate emulsifying agent fuel feedstocks 1-2 water doubly.The moisture particle that these are a large amount of, under the effect of bubble, light specific gravity, with oil be that the proportion of liquid fuel is approaching, so oily water separation is preserved and can not produced in (2-3 month) for a long time, can chemically keep the high emulsified state of stability.
After adding its volume 1-2 water doubly in the concentration emulsifier fuel feedstocks of the present invention simultaneously, on the outer ring of water attached to oil, because of oil in core, oil will produce axial motion when burning, cry pedesis (micropartical in medium produces the heat energy motion, can evoke fluid molecule and become the particulate molecule) again.Oil in core at incendiary in a flash, water is just ignited and is water vapour, produce the water molecules of ultramicronization, when temperature of combustion reaches more than 1350 ℃, in the water molecules hydrogen and oxygen decompose, be formed with and be beneficial to incendiary hydrogen (H) and oxygen (O), save the necessary amount of the air of burning usefulness greatly, thereby reduce the current consumption of boiler; H
2, and O
2Generation can also promote the burning, can be able to perfect combustion (claiming the hydroxide combustion method again) to the clean oil of unburn, the perfect combustion of fuel oil reduces the generation of flue dust and oxynitrides greatly.In common combustion processes, the ratio of hydrogen, oxygen is: oxygen 21%, hydrogen 79%.But adopt emulsion fuel of the present invention to go burning, because the combustion-supporting effect of hydrogen (H) and oxygen (O), the burned flame temperature rises, and improves the thermo-efficiency of fuel oil, therefore only with 1/3 burning, can reach same thermo-efficiency.
Certainly because emulsion fuel amount of water of the present invention is very many, and the minimum needs of its kindling temperature just can be lighted more than 400 ℃, can burn away after catching fire, so when using, the temperature of boiler should be more than or equal to 400 ℃, preferred 400-600 ℃.The boiler high to accumulation of heat, available burning firearm stable operation roasting kiln, but, might must use specific device as under special combustion conditions.
The a spot of combustion air of emulsion fuel of the present invention just can be with fuel oil perfect combustion, can make since due to the incomplete combustion generating capacity of flue dust eliminated, the air capacity that burning is needed reduces, improve flame temperature simultaneously, make oxynitride, as NO
x, SO
x, waste gas generating capacity such as HCL, Dioxins, flue dust reduces significantly.
The present invention adopts the effect of aniorfic surfactant, with fuel oil and the water that cheaply is easy to get by stirring the colloidal emulsifying agent that forms the homogeneous that has bubble, and then liquid hydrocarbon fuel and emulsifier mix stirring, the emulsifying agent fuel feedstocks of its specific concentrated type, after during use concentration emulsifier fuel feedstocks 1.0-2.0 water doubly being sneaked into and stirs, between water and liquid hydrocarbon fuel, form homogeneous and stablize, be difficult to isolating emulsion, improved the chemical stability of emulsion, both can prolonged preservation, can give play to high thermo-efficiency with a spot of combustion air again, temperature of combustion rises, efficiency of combustion improves, play the saving fuel oil, the effect that reduces cost, and can reduce the generation of flue dust and oxynitrides significantly, experiment shows, at boiler combustion process, can produce exhaust gas and smoke and oxynitride hardly, have the excellent comprehensive effect.Available a spot of combustion air can obtain perfect combustion to unburned oil, is without a doubt to the flue dust of incomplete combustion cause, improves the generation that temperature also can lower oxynitride significantly again.
