In the utility model, the emulsification of 7 pairs of fuel combinations of emulsifier is extremely important, described emulsifier 7 comprises a base 11, in the through hole of base 11 1 ends, be provided with nozzle 12, nozzle 12 has a flat slit-shaped spout, the other end of base 11 is the open channel 13 with Tong Guo liquid of a strip, be provided with the wedge shape oscillator 14 that on three-dimensional, to make micro-displacement in the open channel 13, the tip of wedge shape oscillator 14 is over against the flat slit-shaped spout of nozzle 12, one cover plate 15 is screwed the surface in open channel 13, open channel 13 constitutes the emulsification passages, opens cover plate 15 and can safeguard or change the wedge shape oscillators 14 in the open channel 13; Early stage tentatively the liquid of emulsification mixing come out through the flat slit-shaped spout high velocity jet of nozzle 12, enter open channel 13 (being the emulsification passage) over against nozzle 12, the moment that ejects is the mixed once of liquid, but in open channel 13, be provided with the oscillator 14 of the tool wedge shaped tip of a micro-displacement on three-dimensional, the wedge shaped tip part of the positive bump of the mixing material of high-speed motion oscillator 14, when making mixing material further broken oscillator 14 is applied an active force, this active force will make oscillator 14 vibrate on three-dimensional, and form the passage that mixing material flows between two surfaces of oscillator 14 and the open channel 13, the vibration of oscillator 14 applies the particle of multidirectional active force and further broken mixing material again to mixing material, a large amount of minute particles in the mixing material is mixed in the fluid, can thinks that maybe the fuel oil of mixed emulsification shape is that a large amount of water in oil molecules constitutes; Above-mentioned can make the mixed process of mixing material quite complicated on microcosmic at the oscillator 14 that vibrates on the three-dimensional, exist multidirectional active force to be applied on the mobile mixing material, and this multidirectional active force all puts on mixing material in fluid flows through the process of all surface of oscillator 14, so can make mixing material reach very high emulsification degree.
In open channel 13, on three-dimensional, make micro displacement for making above-mentioned oscillator 14, sidewall at oscillator 14 has four blind holes 22, end through the screw thread holder 16 of open channel 13 sidewalls places above-mentioned blind hole 22 and makes oscillator 14 be positioned at the center of open channel 13, between the inner surface of the blind hole 22 of the end of screw thread holder 16 and oscillator 14 sidewalls a minim gap is arranged, the existence in this gap makes oscillator 14 that a micro displacement space all can be arranged on three-dimensional, is equivalent to end intrafascicular approximately that oscillator 14 can be suspended in four holders 16; Remove above-mentioned structure, when oscillator 14 has certain thickness, oscillator 14 has two through holes to run through the two side, through hole through the correspondence of base 11, two fixed axis (not shown)s are fixedlyed connected with base 11 after passing the through hole of oscillator 14, oscillator 14 places the center of open channel 13, and the diameter of fixed axis is slightly less than the diameter of the through hole of base 11, and then oscillator 14 can be at the three-dimensional top offset in the gap that two above-mentioned diameter differences constitute; Above-mentioned gap length can be regulated, and preceding a kind of structure only need be regulated screw thread holder 16 and be got final product, and a kind of structure in back is by the fixed axis of changing different-diameter or the oscillator 14 of changing the through hole of tool different-diameter, the size that just can regulate above-mentioned gap; The difference of gap length, the amplitude difference of oscillator 14 under impact flow then, the size that acts on the reaction force on the fluid-mixing is also different, and then reaches the degree of regulating emulsifying liquid; In the displacement structure of two kinds of above-mentioned oscillators 14, when flow rate of fluid improved, the frequency of oscillation of oscillator 14 improved, the raising of frequency of oscillation, and corresponding emulsification degree also improves.The cross sectional shape of above-mentioned open channel 13 is rectangle or circle, when the cross sectional shape of open channel 13 is rectangle, its structure is the open channel of nozzle 12 over against a rectangle cross section, and open channel is provided with a fixable cover plate 15, and then open channel just constitutes the emulsification passage; The cross sectional shape of above-mentioned open channel 13 is circular, then only needs the passage of nozzle 12 over against a circular cross-section; Aforesaidly the open channel 13 that oscillator 14 is applicable to the rectangle cross section is set, the open channel 13 that oscillator 14 is applicable to circular cross-section is set by fixed axis by screw thread holder 16.
Draw through a large amount of tests, the emulsification degree of mixing material is relevant with the flow regime of mixing material in open channel 13, and the flow regime of fluid is more complicated, and the emulsification degree better.Therefore, one end of described oscillator 14 is a wedge shaped tip, this wedge shaped tip is a flat, tip portion is over against above-mentioned nozzle 12, the other end of oscillator 14 is and above-mentioned wedge shaped tip symmetrical structure, between two wedge shaped tip parts is the tabular linkage section of a square-section, 14 of oscillators form two surfaces, form between the surface of these two surfaces and open channel 13 liquid flow on, lower channel, fluid is by open channel 13 time, at first impinge upon over against the wedge shaped tip part of the oscillator 14 of nozzle 12, mainly be divided into by oscillator 14 then, flowing in two surfaces of following two parts by oscillator 14, converges back outflow oscillator at the afterbody of the other end of oscillator 14.By hydromechanical theory, oscillator 14 is away from the important function that is mixed with of the shape convection cell of an end of nozzle 12, when being symmetrical structure as the wedge shaped tip at the two ends of above-mentioned oscillator 14, fluid mobile more stable can form local turbulent flow at tail end under the situation of laminar flow; Tail end as oscillator 14 is asymmetric wedge shape, and this asymmetric wedge shape is as being shorter than the front end wedge shape of (end over against nozzle 12 is called front end), and then the turbulent flow of tail end is more strong; As tail end is the streamlined curved surface, and then the turbulent flow of tail end relaxes relatively; As tail end is plane, and then the turbulent flow of tail end is the strongest.The front end of above-mentioned oscillator 14 and the structure of tail end wedge shaped tip identical or different can adapt to the emulsification of different mixing materials.
Integrally-built identical or different except above-mentioned oscillator 14 to adapt to the mobile emulsification of different mixing materials, increase the complex flowization of mixing material, help also that fluid is subjected to more active force to increase the fragmentation of liquid particles in flow process in the overall process by oscillator 14 both sides.For reaching above-mentioned purpose, the surface that makes oscillator 14 is a matsurface, and this matsurface is that many small raised lines vertical with oscillator 14 length directions constitute, or is that a plurality of small pits constitute, or is that a plurality of small projectioies constitute; When fluid passed through rough surface, fluid resistance increased, and promptly boundary-layer increases, gradient zones in fluid and oscillator 14 surface formation different in flow rate, increased the interaction force in the fluid, can further increase the degree of crushing of different liquids particle in the fluid, the emulsifiability of mixing material is increased; Above-mentioned oscillator 14 rough surfaces that are made of small raised line or small pit or minute protrusions can be formed by the process technology of routine, or rough surface separately factor constitute or can multifactorly constitute, or can constitute by the other factors outside above-mentioned three kinds of factors, but basic reason all is to increase fluid flow resistance or form a plurality of small turbulent regions to increase the interaction force of mixing material inside on oscillator 14 surfaces, finally increases the emulsification degree of mixing material; Certainly also can form matsurface at the inner surface of open channel 13, also available small raised line of the inner surface of open channel 13 or formations such as groove or pit also can reach the effect of the emulsification degree that increases mixing material; Further, the inner surface of the surface of oscillator 14 and open channel 13 is matsurface simultaneously, can further improve the emulsification degree of mixing material.Because the emulsification degree of mixing material is decided by multiple factor, the multiple factors such as form of the active force that applies of the interaction force between the surface tension of the polarity of the molecule of each liquid or size, liquid, each liquid, the external world that mixing material is subjected to and size thereof, liquid flow for example.In the utility model, mixing material is subjected to behind certain pressure by after spurting into open channel 13 with flat in the nozzle 12, directly clash into the corresponding wedge shaped tip of oscillator 14, oscillator 14 vibrates under the effect of impact, mixing material multi-direction motion back under reaction force is final under the restriction of wedge shaped tip, flow in two surfaces at oscillator 14, the active force of the oscillator 14 that mixing material is vibrated again, also be subjected to the internal action power of the turbulent flow of the frictional force on aforesaid oscillator 14 surfaces and formation, finally further disorderly flowing of the tail end fluid of oscillator 14, a series of fluid flow and multiaction power under, fluid-mixing can reach higher emulsification degree; Be the flow process that promotes above-mentioned fluid and the generation of active force, the length of the wedge shaped tip of the front end of oscillator 14 is 2~4 with the ratio of the thickness of oscillator 14, be preferably 2.5~3.2, when wedge shaped tip above-mentioned length and thickness than scope in the time, fluid-mixing has positive preferably bump to wedge shaped tip, wedge shaped tip has preferable rigidity again and also fluid-mixing is had suitable shunting action, is beneficial to passage or gap that fluid-mixing flows into the both sides of oscillator 15.
The thickness of oscillator 14 is greater than 1.5mm and less than the height of open channel 13 or the full-size of open channel 13, and and form the gap between the inwall of open channel 13, the thickness requirement of oscillator 14 can guarantee that it has certain rigid, weight, simultaneously make fluid-mixing be subjected to the resistance of certain area (being the area of the section of oscillator 14) again, and making the flow velocity on 14 liang of surfaces of oscillator obtain certain raising, the factor of these above-mentioned several respects all helps the emulsification of mixing material.
The front has provided structure and its effect of emulsifier 7 in detail, the effect of emulsifier 7 is extremely important, but multistage (inferior) emulsification and the mobile unobstructed of mixing material of whole device play an important role equally, for guaranteeing the high efficiency flow of above-mentioned mixing material, the output pressure of oil pump 6 is 10~25kg/cm
2For better, oil pump 6 is driven by motor 10, and through the emulsion fuel liquid measure that return duct 23 flows back to voltage-stablizer 5 be oil pump 6 outputs liquid measure 50~80%, under this state, the jet velocity of the liquid in the emulsifier 7 can reach a high value, the frequency of oscillation of oscillator 14 is also higher, emulsified at least device 7 emulsifications of liquid three times; Or oil pump 6 output pressures are 18~22kg/cm
2, the emulsion fuel liquid measure that flows back to voltage-stablizer 5 through return duct 10 be oil pump 6 outputs liquid measure 65~72%; For further the effectively mobile of the liquid in the whole device that guarantee, on water inlet pipe 2, be provided with water meter 17, entering water electromagnetic valve 18 and control valve 19, on return duct 23, be provided with pressure check valve 20, can in time regulate water oil input or input ratio.
Water in the fuel combination that the utility model uses can account for total amount 5~30% in regulate, above-mentioned so-called water accounts for 5~30% and is meant that its burning is fully effectively, in actual use, emulsion fuel generally is through a nozzle combustion jet to be gone into combustion chamber, at this moment emulsion fuel must be have pressure and sufficient quantity, general quantity delivered is greater than the actual amount that sprays into combustion chamber, unnecessary fuel then can be back to voltage-stablizer 5 through a user's return duct 21 that is connected with voltage-stablizer 5, can guarantee that then whole device liquid in use is unobstructed; Be the damage of emulsifier 7 in oscillatory process that prevents to occur, behind oil pump 6, connect a preceding four-way 24, four-way 25 after one of the termination before the threeway 8, two outlets of preceding four-way 24 connect two inlets of four-way 25 afterwards after connecing an emulsifier 7 respectively again, another outlet of preceding four-way 24 directly is connected with an inlet of back four-way 25, then form two pipelines in fact with emulsifier 7, when a pipeline goes wrong, another pipeline then can start, between preceding four-way 24 and emulsifier 7, be provided with ball valve 26, for regulating the fluid pressure in the whole device at any time, in preceding four-way 24, be provided with a Pressure gauge 27 with monitor pressures; Voltage-stablizer 5 also is provided with user's return duct 21, also is provided with gas and oil separating plant on user's return duct 21.
Total of the present utility model is simple relatively, but because the good oscillation effect of emulsifier 7, make the fuel combination emulsifying effectiveness very good, the control of flow makes emulsification, combustion through repeatedly emulsification in the device simultaneously, the diameter that finally makes the particle water in the fuel combination is about 10 μ m, and most of particle water can be at 5-7 μ m particle diameter, and particle water distributing very evenly in fuel combination is so adapt to various combustion apparatus.The utility model is adapted to all size equipment, gasoline engine, diesel engine, heavy oil combustion stove etc., can reach at rate of economizing gasoline under the situation of 10-20%, also can greatly reduce the pollution of discharging, but be the emulsifying device that a kind of commercial scale is used, have crucial economic worth.
