Abstract

The present invention relates to a heavy oil additive which is a high-efficient energy-saving additive for the combustion of heavy oil added with water. The heavy oil additive is composed of regulating agents (a, b), combustion promoters and antimildew agents. The present invention has the characteristics of good high-temperature stability, no layering and no emulsion breaking at 90 to 105 DEG C, bright flame, easy control, 20% of fuel saving ratio, cost greatly lower than that of any heavy oil additive at home and abroad, and little environmental pollution; the present invention can be widely applied to metallurgy, chemical industry, glass, ceramics, enamel and other industries using the heavy oil as fuel.

Description

Heavy oil additive

The present invention relates to a kind of heavy oil mixed with water incendiary efficient energy-saving additive.It not only is applicable to thermal treatment and metallurgy industry, and all are the industry of fuel with heavy oil to be widely used in chemical industry, glass, pottery, enamel and other.

Energy problem is the great war preparedness problem of attracting worldwide attention, concerning all fields of mankind's activity.The energy policy of China is: " exploitation is laid equal stress on saving, puts prior energy-conservation in the recent period, and carrying out energetically with energy-conservation is the technological transformation and the structural reform at center ".All pay attention to energy-saving application Study on Technology and popularization at present both at home and abroad, external, heavy oil mixed with water burning and emulsifying technology are used for the poor efficiency boiler, and process furnace has all entered the practicability stage.Recently, after the 56 tame users of U.S. Rork Telecom use technology for mixing water in heavy oil, fuel-economizing 5.3～13.5%, Japan is from the sixties also develop actively fuel water technology, and rate of economizing gasoline is 5～25%.

China since the sixties just to the research (ultrasonic emulsification, machine stirring and emulsifying etc.) of fuel emulsification, obtain certain achievement, but because the oil in water emulsion poor stability, combustion efficacy is not good enough.In July, 1984, " the energy-efficient element of HPE " studied successfully by department of chemistry of Zhongshan University, and energy-efficient plain factory produces in the hengyang, hunan province city, applies, according to data report, rate of economizing gasoline 5～27%.According to energy-conservation research group of department of chemistry of Zhongshan University in May, 1986 report " in research that HPE is energy-efficient and the application data; the HPE price is 25 yuan/kilogram; the energy saving element TEM price that the wide good fortune in Hong Kong company produces be 130 Hongkong dollars/liter; the energy saving element Uq that the U.S. super source company produces, price is 37.2 dollars/liter.More than various energy saving element valencys cost an arm and a leg on the one hand, actual production is used, and drops into the auxiliary agent cost and balances or cancel each other with the fuel-economizing cost, it is not ideal enough to save value, user's enthusiasm is little; The high stability of oil in water emulsion does not reach a standard as yet fully on the other hand, generally at 80～90 ℃ the layering demulsifying phenomenon takes place, and causes boiling explosion phenomenon, disturbs stove internal combustion operating mode, and oil-saving effect is not in full use.

The purpose of this invention is to provide that a kind of high-temperature stability is good, cost is low, the additive for heavy oil of the obvious economic of fuel-economizing.

The present invention is achieved in that it is made up of conditioning agent a, the ignition dope that contains organic material, mould inhibitor, conditioning agent b.Conditioning agent a is a heavy oil, and it contains a large amount of bituminous matters, colloid, cured matter, its heavy oil of being made up of to multiple heavy hydrocarbons such as 36 alkane 17 alkane.The ignition dope that contains organic material is the waste liquid throw out that gives off of paper mill or evenly adds 5～20% 40～100 purpose coal dusts again in the waste liquid throw out of paper mill.Mould inhibitor is with sodium pentachlorophenate or Sodium Benzoate.Conditioning agent b adopts the sex change grease, and its effect is the flowability that increases mixed solution.Each component of this additive for heavy oil is by weight as follows: conditioning agent a is 100kg, and ignition dope is 600～1000kg, and mould inhibitor is 3～10kg, and conditioning agent b is 30～35kg.

Fig. 1 is preparation technology's schematic flow sheet of additive for heavy oil of the present invention: be metered into ignition dope (1), mould inhibitor (2) and conditioning agent a(3 according to the above ratio) in mixing tank (4), mixing temperature is controlled at 80～90 ℃, uniform mixing, and then adding conditioning agent b(5), enter mixing tank (6) once more, stir, temperature is controlled at 80～90 ℃, 30 minutes time, up to becoming uniform emulsifying dispersant, can enter packing (7) and go into bucket, become the finished product (8) of additive for heavy oil.Pail pack can adopt metal drum also can adopt plastic barrel, but the additive temperature of plastic barrel can not be higher than 40 ℃.

Fig. 2 is the applicating flow chart of additive for heavy oil of the present invention: additive for heavy oil (9) is metered into mixing tank (13) through gauger (10); Water (11) enters mixing tank (13) simultaneously through gauger (12) metering, enters emulsor (17) again; Heavy oil (14) is through preheater (15), preheating temperature is 80～90 ℃, and by gauger (16) metering, it is even to enter emulsor (17) emulsification again, squeeze into preheater (19) with pump (18), the nozzle (20) by burner is in kiln or stove (21) internal combustion at last.The some globules that contained in the oil in water emulsion are subjected to thermal evaporation to produce the intensive volumetric expansion, make mist of oil drip fragmentation, cause " secondary-atomizing " of mist of oil, because secondary-atomizing, female dripping disappears, and the substitute is the small particle of countless oil not of uniform size.Increase the area of oil mist combustion reaction, realized low oxygen combustion, brought the following effect of the present invention thus:

1. has high-temperature stability preferably: 90～105 ℃ of not stratified, breakdowns of emulsion not.Vaporization is uniformly only taking place more than 90 ℃, and the boiling explosion phenomenon that produces because of layering can not take place.Total system is under the effect of micro-explosion situation works.

2. the total addition level of additive of the present invention and water can reach about 25%, wherein amount of water is 17.5%, but the solids component in ignition dope energy ignition itself has enough calorific values, so rate of economizing gasoline can surpass contained Total Water, reduce because of crossing and add the thermosteresis that water causes.

3. if this additive is to be used for kiln or stove, can also in additive, add 5～20% 40～100 purpose coal dusts equably, coal dust instead of part heavy oil like this, rate of economizing gasoline is bigger, reaches as high as 45%.

4. additive factory cost of the present invention is low, and only 500 yuan per ton, during use, if addition 10～15% so the additive cost is 50～80 yuan in the oil in water emulsion per ton, is that other any energy saving element price is incomparable.

5. reduce of the pollution of paper mill black liquor, have good social benefit and economic benefit environment.

Embodiment:

The black liquor that the paper mill is given off adds 15% calcium chloride solution and stirs at a slow speed, after producing a large amount of flocculated suspension things, filter through plate-and-frame filter press, and in filtration procedure continuous eccysis water soluble salt material wherein, promptly get the used ignition dope of the present invention.Each component of this additive for heavy oil is by weight: 830 kilograms of ignition dopes, 150 kilograms in heavy oil, 30 kilograms of sex change greases, 3 kilograms of Sodium Benzoates.Mix in mixing tank and stir, the control whipping temp is 80～90 ℃, and churning time 30 minutes promptly gets the uniform additive for heavy oil of emulsification.
