Abstract
An emulsified water-in-oil diesel oil contains diesel oil (60-90 %), water (10-40%) and emulsifier which is prepared from sodium dodecylbenzylsulfonate (0.1-0.16 wt%) and Span 80 (0.7-1.2 Wt%).
Description
The invention relates to the fuel oil of oil engine, particularly diesel oil emulsification about watering.
People at research diesel oil in diesel during the incendiary situation, if find in combustion processes, to add the water (generally accounting for about the 10-40% of gross weight) of appropriate amount, can improve the combustion conditions of diesel oil, play making the clean-burning effect of diesel oil, thereby can reduce fuel oil consumption and oke exhaust blackness.A burst of diesel oil heat of watering has also been risen in China in the sixties in 20th century.Owing to be directly diesel oil and water to be sprayed into cylinder through oil nozzle together by additional water tank to burn at that time by oil injection pump.But the state that waters in this fuel oil is unfavorable to the startup of engine, and behind engine shutdown, wants ponding in the cylinder, is easy to generate corrosion, so the valve of can only can fetching boiling water after diesel oil work for some time waters; Use pure diesel oil work for some time instead and can shut down and before flame-out, must close water valve.So the trouble of use, easy ponding, impurity filtered in the corrosion machine, particularly water often causes the obstruction of oil nozzle.The defective that for a change above-mentioned diesel oil directly waters and causes, people have carried out diesel oil and emulsive is explored and research.Owing to the emulsifying agent difference of using, the emulsification pattern of so-called oil-in-water and two kinds of patterns of water-in-oil is arranged.On May 5th, 1999, publication number was that the application for a patent for invention of CN1215747A " preparation method of diesel oil emulsifier and diesel oil emulsification thereof " is exactly a kind of diesel oil emulsification example of water-in-oil-type, the diesel oil emulsification that it can make water-in-oil-type with water and the diesel oil of 10-40% (weight percent), and can reach the effect of economizing on oil and reducing oke exhaust blackness through bench testing.But till before proposing to the present invention, the following defective of existing various diesel oil emulsification ubiquities: 1, the used raw material variety of emulsifying agent is various, preparation work is complicated.For example above-mentioned patent application public use eight kinds of raw materials, and under the temperature condition of regulation, operate in two stages, 2, the particle of diesel oil emulsification is too thick, and it is inhomogeneous, there is granularity greatly to be lower than 800 orders, can not pass through the filtration slit of engine diesel oil filter element smoothly, thereby oily water separation under the pressure effect of transfer pump, what therefore enter engine cylinder not exclusively is the diesel oil emulsification of water-in-oil-type, but contain portion water, the mixture of diesel oil and diesel oil emulsification, life-time service very easily forms ponding like this, not only machine is caused corrosion, and cause the cold start-up difficulty easily, and often cause the engine auto extinguishing.So, also do not have a kind of diesel oil emulsification really to obtain user's employing so far.
The object of the present invention is to provide a kind of emulsified water-in-oil diesel oil, it overcomes the above-mentioned defective of existing diesel oil emulsification, not only the raw material variety of its emulsifying agent is few, emulsion process is convenient and swift, and its emulsive granularity is all more than 800 orders, can pass through the filtration of diesel oil second filter smoothly, can not produce the phenomenon of oily water separation, and can still keep original emulsified state after the standing storage.
The object of the present invention is achieved like this:
A kind of emulsified water-in-oil diesel oil comprises the diesel oil of 60%-90%, and the water of 10-40% and emulsifying agent is characterized in that: described emulsifying agent is Sodium dodecylbenzene sulfonate and span 80; Its consumption is respectively (weight percent):
Sodium dodecylbenzene sulfonate 0.10-0.16% span 80 0.7-1.2%.
Above-mentioned emulsified water-in-oil diesel oil is characterized in that: described Sodium dodecylbenzene sulfonate was dissolved in earlier in the described water about 5-6 hour, and with described span 80 stirring and dissolving in described diesel oil, more above-mentioned two kinds of solution are mixed the back and stir and getting final product.
Above-mentioned emulsified water-in-oil diesel oil, it is characterized in that: can with a spot of diesel oil and water in advance with described emulsifying agent under turning left right speed conditions, stir at the temperature about 60 degree and per minute 960 be no less than 3 minutes after, be cooled to room temperature to make the emulsion of different concns, above-mentioned emulsion stirred under the condition of 1440 rev/mins of left and right sides rotating speeds with quantitative diesel oil and water by required profit proportioning be no less than 3 minutes at last.
The present invention has following advantage:
1. emulsifying agent only uses two kinds of starting material, is convenient to purchase and gets the raw materials ready.
2. be the good solvent of Sodium dodecylbenzene sulfonate owing to water, and diesel oil also is the solvent of span 80, therefore emulsifying agent can be dissolved in respectively in water and the diesel oil, directly makes diesel oil emulsification through mixing to stir, simple and efficient.
3. viscosity and mobile and pure diesel oil type seemingly and have good lubricated and rustless property.
4. granularity is little and even, about about 2 microns of the diameter of its droplet, can be smoothly fine filtering core by diesel oil second filter 800 sighting slit crack sizes, can oily water separation and form ponding.And existing diesel engine needn't do any repacking and just can directly use,
5. emulsifying effectiveness is stable, but oily water separation does not take place in standing storage (being no less than 40 days), does not have jelly and throw out yet.
6. good anti-condensation performance, behind No. 0 diesel emulsion of test use, being under-7 ℃ to-15 ℃ conditions did not still have solidification phenomenon through 3 hours, compared No. 0 diesel oil condensation.
7. the present invention can be earlier makes emulsion in advance with emulsifying agent and a spot of diesel oil and water, and then makes diesel oil emulsification by actual ratio requirement, therefore operation very flexible, be suitable for.
