Additive of the present invention is used to produce nanometer emulsion fuel, concrete using method is: the water of 0.1～5% additive of the present invention of weight percent, 50～89.9% liquid fuel and 10～49.9% is joined the rotating speed with 3000～4000 rev/mins stirred 20～50 minutes in the high pressure homogenizer, with high-pressure pump above-mentioned emulsification is got well-proportioned material then and be input in one group of static mixer and carry out second emulsifying, the particle diameter of the fine globule in the emulsion fuel is got final product in the scope of 10～100nm.
Additive of the present invention has the following advantages.
One, the fuel of additive preparation of the present invention has permanent stability.Use nonionogenic tenside in the additive of the present invention.Nonionogenic tenside has hydrophilic group and hydrophobic group, and during hydrophilic group is soluble in water, and hydrophobic group is soluble in organic phase, and water and oil are ideally combined, and is not separated for a long time.Compare with cats product, anion surfactant, ionization does not take place in nonionogenic tenside yet in the salt of acidity, alkalescence or hard water, and cats product, anion surfactant ionization in water, react with other material and to generate precipitation, and the nonionogenic tenside unionization, exist with central element or micella state, promptly form water-in-oil-type neutral molecule micella, have the ideal chemical stability.
Two, use the fuel of additive preparation of the present invention can make wherein the globule have the particle diameter of 10～100nm, particle diameter is far smaller than visible wavelength like this, produces transparent outward appearance.Product stationary phase is more than 1 year.
Three, use the fuel of additive preparation of the present invention to have and fall dirty and energy-conservation unique features.Environmental monitoring junction centre in Henan Province's has carried out the discharge monitoring of Air thing in March, 2004 to the diesel oil fuel that adds additive of the present invention, and has provided monitoring report (No. the 10th, Henan environmental monitoring son (2004)).The diesel oil fuel that adds additive of the present invention is additive 1.6%, 0# diesel oil 79% and water 19.4%; Contrast fuel is 0# diesel oil.
| Fuel | Flue dust mg/m 3 | SO 2 mg/m 3 | NO x mg/m 3 | Blackness of exhaustion | Noise dB (A) |
| 0# diesel oil | 26 | 154 | 201 | ＜1 grade | 66.2 |

Diesel oil emulsification is an aqueous fuel, and water is not that fuel can not burn, and just because water participates in burning, makes combustion processes optimized.Diesel oil emulsification produces " microexplosion " in combustion processes, make the burning of fuel complete, and efficiency of combustion gets high.The carbon granule that does not burn has " water-gas reaction " to take place in the presence of water vapor, generates H
2And CO, then H
2To produce activity core, begin a series of chain reactions then, produce H, O and OH atom and active substance, activate whole combustion processes greatly.Owing to strengthened combustion processes, make burning more abundant, realized good dirt and the energy-conserving action of falling, thereby made smoke intensity and dust concentration in the exhaust significantly reduce SO
xAnd NO
xAlso can correspondingly reduce.
The diesel product that adds additive of the present invention has carried out half type approval test of engine pedestal combustion test and hot water boiler, has obtained environmental protection and energy-conservation gratifying result.Now test-results is summarized as follows:
1. oil-saving effect:
(1). on 15 horsepowers of single cylinder diesels, carried out use and bench testing, with 0
#It is 2-8% that diesel oil is compared rate of economizing gasoline.
(2) use and stand combustion test on 75 horsepower of six cylinder engine generator set, have been carried out, with 0
#Diesel oil is compared rate of economizing gasoline 5-17%, and every kilowatt-hour of (KWH) specific fuel oil consumption reduces 7-18%.
(3) on 100 horsepowers of six-cylinder diesel engines, carried out the stand combustion test, with 0
#Diesel oil is compared, and when the 2300r/min specified speed, specific fuel consumption (KWH) reduces 4-5%, and when 1500r/min, specific fuel consumption reduces 2-20%.
(4) on the hot water boiler of the Italy of 30000 kilocalories per hour hundred moral board import burners, carried out combustion test.With 0
#It is 4-9% that diesel oil is compared rate of economizing gasoline, and the efficiency of combustion of fuel is than 0
#Diesel oil improves 4%.
(5) carry out combustion test on the food and drink kitchen range, with 0
#It is 10-18% that diesel oil is compared rate of economizing gasoline
2. dirty effect falls in environmental protection
(1) when 100 horsepowers of six-cylinder diesel engine stand combustion tests, carried out the smoke intensity in the exhaust and detected, with 0
#The diesel oil ratio, when 2300r/min, the discharge value of smoke intensity has reduced 11-22%, when 1500r/min, reduces 30-39%.
(2) when having carried out combustion test on the Italy of 30, the 000 kilocalories per hour hundred moral board import burner SF-50K hot water boilers, with 0
#Diesel oil is compared, and dust concentration has reduced 42-46%, and the dust concentration value mistake far away of littleization diesel oil is lower than set quota.
From above-mentioned oil-saving effect and fall dirty effect as can be seen: the about 7-12% of the rate of economizing gasoline of diesel oil emulsification, and it is very remarkable to fall dirty effect.At present, it is up to standard that dust concentration value in Zhengzhou City's boiler combustion exhaust is difficult to, and more chimney need add fly-ash separator and also be difficult to realize value up to standard, and emulsion fuel must not add any addition thereto can be up to standard, and well below set quota, the prosperous and powerful vitality of diesel oil emulsification is just appeared vividly.
Four, production technique and equipment are simple.The technology for preparing additive of the present invention and use its to prepare fuel all needs only to stir can prepare thermodynamic stable system, as clear as crystal.
Five, additive quality of the present invention is guaranteed, cheap.This can find out significantly from the raw material that uses.
