Description

A kind of improved mink cell focus ignition dope

The present invention relates to a kind of improved mink cell focus perfect combustion catalyzer.

Mink cell focus such as heavy oil, residual oil are formed because of mainly containing oily the group, and viscosity is bigger, is unfavorable for abundant burning, by adding various ignition dopes, can change its characteristic and catalytic combustion-supporting, reach to improve burning carbon deposit and black smoke discharging in minimizing and the removing oil atomizer gun.It is calcium, cobalt, iron, manganese and the compound composition ignition dope of five kinds of naphthenate catalysts of zinc that Chinese patent 92103518 discloses with 10-30% ditertiary butyl peroxide initiator and surplus, this main by the composite ignition dope of forming of metallic naphthenate, its main drawback is that emulsifying property is poor, can not adapt to various stoves uses, and it is good inadequately to add rear stability, along with time lengthening is prone to precipitation, layering, thereby not anti-storage; Naphthenic acid is low in conjunction with the ability of catalytic metal ion because of the low influence of acid number, and the catalytic combustion-supporting effect is not really desirable; Naphthenic acid is because flash-point is low besides, and production, transportation, storing stability are poor.Therefore still having is worth improved place.

The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of and have efficient emulsification, catalytic combustion-supporting, eliminate smoke, remove contamination in one, the mink cell focus perfect combustion catalyzer that combustion-supporting effect is good.

The object of the invention realizes, the main improvement is that multiple organic emulsifier of employing and isocaprylic acid metal-salt are composite, specifically, heavy oil residual oil ignition dope of the present invention, it is characterized in that having the sorbitol list glyceride (trade(brand)name S-80) of 50-70%, the sorbyl alcohol glyceride Soxylat A 25-7 (trade(brand)name T-80) of 1-10%, the rouge ethanol sodium sulfate (claiming 12 pure sodium sulfate again, trade(brand)name K-12) of 0.1-1%, the manganese iso-octoate of 1-15%, the cobalt iso-octoate of 1-10%, the isocaprylic acid iron of 10-20%, the composite composition of isooctoate of rare earth metal of 1-10%.Isooctoate of rare earth metal of the present invention is preferably for adopting the group of the lanthanides rare earth chloride.Described isocaprylic acid iron preferably uses the ferric iron of isocaprylic acid.For making the catalytic combustion-supporting better effects if, reduce corrosion of metal damage also is added with the isocaprylic acid copper of 1-10% in the ignition dope of the present invention, isocaprylic acid copper preferably uses the cupric of isocaprylic acid.

S-80, T-80 are emulsifying agent among the present invention, and good solvability is arranged in middle High Temperature and Heavy Oil, play emulsifying effect, make the fine combination of energy under the effect of emulsifying agent of oil, water, form oil in water emulsion.K-12 mainly opens the oil group in heavy oil, the residual oil, and the viscosity of oil is descended, and helps emulsification.2-ethylhexoate mainly plays the combustion-supporting effect of catalyzed oxidation.Therefore add ignition dope of the present invention, and after adding the water of suitable quantity of water such as 20-30%, can make heavy oil, residual oil under the emulsifying agent effect, form the trickle pearl that water-in-oil such as diameter are about 3mm, after this water-in-oil microballon enters the combustion chamber, because of high temperature expands rapidly, gasification, the tiny oil droplet of ejection is burst be superfine little mist of oil, the surface-area of oil droplet increases several times rapidly, this process is called " effect of micro-explosion ", can make burning more abundant, thorough.The chemical reaction of a series of complexity, the H of generation can take place again with the oil inflame product in the water vapour of oil in water emulsion generation at high temperature simultaneously ₂With CO than oil easy firing more, they are adsorbed on the oil film surface, can remove oil film surface C O ₂And N ₂The air film that forms, thus make the heat passage of oil droplet rapider more abundant with burning, be referred to as " stripping effect ".The catalytic combustion-supporting of ignition dope has also reduced " activation energy " of heavy oil combustion, also helps the abundant burning of heavy oil, residual oil.Because above-mentioned acting in conjunction makes heavy oil, residual oil can reach abundant burning and manifest oil-saving effect, its comprehensive rate of economizing gasoline can reach 15-20%.

The preparation of ignition dope of the present invention only needs above each component is mixed in proportion, gets final product through stirring.

Further specify the present invention below in conjunction with several embodiment.

Embodiment 1: with commercially available S-80 57Kg, T-80 10Kg, K-12 1Kg, manganese iso-octoate 10Kg, cobalt iso-octoate 8Kg, group of the lanthanides isocaprylic acid rare earth chloride 9Kg, isocaprylic acid ferric iron 5Kg, mixing was stirred through 1 hour, add in the mink cell focus with 0.1% addition, water mixing 20-30% uses average rate of economizing gasoline 15-20% in stove.

Embodiment 2: with commercially available S-80 70Kg, T-80 1Kg, K-12 0.5Kg, manganese iso-octoate 2.5Kg, cobalt iso-octoate 2.5Kg, group of the lanthanides isocaprylic acid rare earth chloride 2.5Kg, isocaprylic acid ferric iron 11Kg, isocaprylic acid copper 10 Kg, mix through 1 hour and stir.

Additive of the present invention is owing to adopt multiple efficient organic surface active agent and isocaprylic acid catalysis burning-rate accelerator compounded combination, have better emulsifying effect and catalytic combustion-supporting effect than correlation technique, therefore but water mixing is used, watering quantity can reach 20-30%, not only make the heavy oil, residual oil can be fully emulsified, and burning is more abundant under the catalyzed oxidation of ignition dope, and its comprehensive rate of economizing gasoline can reach 15-20%.Sufficient combustion can also reduce the black smoke discharging, improves the kiln burning situation and burns till quality, can improve the clear rate 4% of folding in burning till as terra-cotta, and steel mill can reduce steel surface oxide skin and produce.Ignition dope of the present invention also has the residue decomposition ability, can make the big particle of the heavy carbide residue in heavy oil, the residual oil resolve into tiny carbide particulate, they are atomized by oil nozzle rapidly, both can effectively prevent the obstruction of oil nozzle, and again under the effect of " effect of micro-explosion ", make the oil nozzle coking obtain removing, can also prolong the work-ing life of oil nozzle and alleviate the labour intensity of removing the oil nozzle coking.Because carbon distribution is eliminated, and has reduced the incrustation of burner hearth, improved the heat transfer of boiler again, can improve thermo-efficiency.The abundant burning of heavy oil, residual oil can also reduce because of high sulfur-bearing makes burning generating more SO ₂And S ₃To equipment corrosions such as engine, boilers.Ignition dope of the present invention, identical because substance is acidity with oiliness, can layering because of acid-base neutralisation.
