Abstract
The method and apparatus of emulsifying fuel-oil by water stream, it is to adopt water vapour to make fuel-water emulsifying, the waste heat water that used water vapour can utilize internal combustion engine or other oil burning apparatus produces during to fluidized state.Its device has steam generator, steam needle-valve, oily vapour hybrid chamber, oily vapour emulsification chamber.Be equipped with oil emulsion with this legal system,, do not consume any type of useful work, also do not have the difficulty on storing and transporting, thereby have tangible use value and economic benefit without emulsifying agent.On the S195 diesel engine, 3% above rate of economizing gasoline can be obtained, and smoke intensity, particle and harmful gas emission can be significantly reduced with this method.
Description
The invention belongs to a kind of method of the fuel-water emulsifying that uses at random for internal combustion engine and other oil burning apparatus.
Current, the emulsion fuel of development adopts the scheme of the outer preparation of machine mostly both at home and abroad, although its method is a lot, have only the oil emulsion quality of a few method preparations such as electricity is ultrasonic, resonant wedge whistle better, but special equipment is complex structure mostly, all to use without any exception during preparation than fuel cost expensive the emulsifying agent of Duoing, and want consumed power or mechanical power.The oil emulsion of making store and can not guarantee not take place between the operating period oil, moisture from.Though internal combustion engine and other oil burning apparatus have oil-saving effect when using this fuel, can reduce smoke intensity and NO
XConcentration of emission, but disbursement usually exceeds fuel-economizing gained economic benefit.Be example now with tween (Tween) and this (Span) such emulsifying agent of department, as use amount is 0.5% of emulsion fuel total amount, then disbursement will be that 6～10% fuel costs of being saved equate with rate of economizing gasoline, under the not high situation of rate of economizing gasoline, also inversion phenomenon can take place, therefore directly influence promoting the use of of oil emulsion.
For this reason, have the people to study preparing oil emulsion at random both at home and abroad, its purpose is few usefulness or without emulsifying agent, to manage to improve the economic benefit of using oil emulsion.Yet, up to now, desirable preparation method does not appear as yet, and its main cause is few usefulness or without oil emulsion inferior quality prepared behind the emulsifying agent, the fuel-economizing performance is bad, wants consumed energy in the same old way, though purification function is arranged, economic benefit does not improve.
Purpose of the present invention makes the application of emulsion fuel that a breakthrough be arranged for various internal combustion engines and other oil burning installation provide a kind of without emulsifying agent, also do not consume useful energy and the new method of obvious fuel-economizing and the emulsified fuel at random that purifies benefit is arranged.
Main points of the present invention are to adopt water vapour to prepare oil emulsion, when internal combustion engine or the work of other oil burning apparatus, the water vapour that steam generator produces can be introduced fuel oil emulsifier through steam bottle, in emulsifier unit with from fuel tank, also meet through the diesel oil of filtering, through mixing, condensation and radiating treatment, just can prepare the oil emulsion that water particle is evenly distributed and particle diameter is trickle in oil.The waste heat water that the water vapour of steam generator can utilize engine and burner produces during to fluidized state.She Ji a kind of emulsifier unit has steam needle-valve, oily vapour hybrid chamber, oily vapour emulsification chamber according to the method described above, and oily vapour hybrid chamber can be made up of oil nozzle, steam nozzle, nozzle block, oily vapour emulsification chamber can by tighten up plug screw, emulsification chamber joint is formed.
As shown in Figure 1, steam generator (5) and steam bottle (4), to draw vapour emulsifier unit (3) be the critical component of implementing the fuel oil emulsifying method that the present invention proposes.Steam generator can be the water tank of transpiration-cooled engine, also can be the blast pipe that has cooling jacket that designs separately.Steam bottle has collection vapour concurrently and two functions of vapour amount are drawn in control.Drawing vapour breast device is the place of making oil emulsion after oil, the mixing of vapour process, the condensation, coming, the water vapour from steam generator (5) and steam bottle (4) meets in emulsifier unit from the fuel oil of fuel tank (1) and cleaner (2) and another road, through mixing, condensation, liberated heat loses when in time making the water vapour condensation, thereby make water vapour constantly in oil, be condensed into the suspension water particle in a steady stream, make astable water-in-oil emulsified.After making, uses through fuel pump (6) input fuel feed system immediately oil emulsion.Because oil emulsion is very short from the time that is made to use, the W/O grain also has little time to assemble and separates, so stability does not have problems.
As shown in Figure 2, this chief component that draws the vapour emulsifier unit comprises housing (8), oil nozzle (9), steam nozzle (10), nozzle base (11), fastening plug screw (13), emulsion tank joint (14) and steam needle-valve (16).The steam needle-valve is in normally open when engine or the work of other oil burning apparatus, so that steam flows into emulsifier unit through needle-valve by the steam nozzle.When fuel oil enters the M shape cavity of emulsifier unit by pipe joint (7), just in time with vertical direction on enter the M cavity through air nozzle (10) steam meet, two plume bundles are handed over mutually and are mixed, and form the vortex in the M cavity, thereby provide good condition for oily vapour mixing and emulsifying.The supercharging of slowing down in the M cavity of mixed fluid obtains throttling once more and quickens when the minimum vias of the part of flowing through (11), this is favourable to further formation fuel emulsification.Below in base (11), the emulsion tank cavity volume that is made of part (13) and (14) has an optimum value, big instead can make the oil emulsion overstand, and oil emulsion stability is degenerated; Little, when also being unfavorable for the work of the preparation of oil emulsion and engine or other burner to the requirement of fuel oil supply.The oil emulsion of making promptly enters fuel oil supply system through pipe joint (15) after the emulsion tank inner chamber stops a little, to adapt to system with the needs of using.
As shown in Figure 3, the steam bottle on a kind of S195 of being used for diesel engine is installed in above the water tank (24), and its critical piece comprises pressure equalizing chamber and steam chest two parts.Pressure equalizing chamber is made up of dummy piston (21), piston cylinder (20).Piston weight has strict demand, so that vapour pressure remains on prescribed limit in the steam chest, and then carries out strictness and controls drawing the vapour amount.When vapour pressure overshoot value, piston rises in cylinder, and bleeder port (19) exposes, and makes steam excessive, no longer raises to keep steam pressure.Steam chest mainly is made up of outer cover (22) and steam inducing tube (23), and 8 apertures are arranged at the steam inducing tube top, and aperture is away from liquid level, with the steam that guarantees the to enter aperture water particle of vaporization not; Steam inducing tube passes water tank inside, and connect with the steam inducing tube that draws the vapour emulsifier unit (17) at water tank bottom, can make like this that steam is not less than 100 ℃ in the pipe, and unlikely generation condensation, making and entering what draw the vapour emulsifier unit is steam but not water particle, unaffected to guarantee the emulsion process of carrying out subsequently.
