Description
Technical field
The utility model relates to a kind of fuel-water emulsifying firing unit, and it is particularly suitable for Emulsion Combustion of Bunker Oil Mixed with Water.
Background technique
Along with Chinese economic development, to the energy, particularly the demand of oil will be doubled and redoubled, and the breach of future source of energy supply and demand is with increasing.The thermal efficiency is higher owing to having for diesel engine, oil consumption is low and fuel fire danger is urinated in characteristics such as storage transportations, be widely used in the big-and-middle-sized equipment such as automobile, agricultural machinery, naval vessels, tractor, tank, thereby become genuine oil consumption rich and influential family and important pollution source.Because an urgent demand of energy-conservation and environmental protection two aspects, countries in the world all begin various research and the improvement that improve oil inflame performance and diesel engine fuel oil burning (machinery) environment.For, the latter is an elder generation with firing chamber, oil sprayer with oil emulsion for the former.Diesel oil emulsification is a diesel oil, the synthetic of water and emulsifier, it utilizes the surface activity of emulsifier, reduce the surface tension of water, oil and water are with W/O or with the appearance of the form of O/W, this oil that exists with the form of mixture, though improved the combustion performance of diesel oil largely, but under different temperature and different environment, be easy to occur breakdown of emulsion (oil-water separation), when reaching 100 degrees centigrade in serviceability temperature, water will evaporate or break away from, and is very unsettled mixture therefore, and need professional produce in factory, exist to be difficult for storing, use inconvenient, transportation and the higher shortcoming of manufacture cost.And the Machine Design manufacturing of firing chamber, oil sprayer has been becoming better and approaching perfection day by day by years of development, limit by research method, manufacture method and material, and the hope that makes a breakthrough on its function and structural design at present is very little.
The model utility content
The purpose of this utility model is to provide a kind of fuel-water emulsifying firing unit, and it has concurrently energy-conservation and environmental protection two big characteristics.
The purpose of this utility model is achieved through the following channels: a kind of fuel-water emulsifying firing unit, its fuel tank, oil and water seperator, oil transfer pump, diesel-oil filter, Injection Pump are linked in sequence by low pressure fuel pipe, the Injection Pump the other end is connected with oil-water mixer oil-in end with high-pressure oil pipe, water tank, water transport pump, water filler, water jet pump are linked in sequence by the low pressure water pipe, the water jet pump the other end is connected with the oil-water mixer water inlet with high-pressure water pipe, and the oil-water mixer outlet end is connected with oil sprayer; The inner oil-water mixer of installing of described oil-water mixer.Be enclosed with circulating water cooling ring on the oil sprayer outer wall.Described oil-water mixer is the metal wire structure that multiple layer metal web frame or pencil distribute.
The utility model fuel-water emulsifying firing unit increases by one tunnel water supply combination identical with fuel feeding in the diesel engine supply system, increase oil-water mixer, instant preparation aqueous dispersion fuel (micro emulsion oil), increase the oil sprayer air ring, guarantee the physicochemical property of aqueous dispersion fuel, utilization " microexplosion " theoretical principle is realized the direct emulsifying combustion of diesel engine.It need not to change burning chamber of diesel engine and oil sprayer, technology is simple and easy, easy to prepare, with low cost, need not during emulsifying combustion to add chemical reagent such as any emulsifier and combustion improver, but can reach the firing effect of oil emulsion, and not have the sorrow of oil emulsion layering, breakdown of emulsion, be not subjected to the influence of serviceability temperature, Environmental Conditions, can be widely used in the diesel engine is in the various equipment of power source.This technology can be saved fuel oil 25-30%, reduces exhaust emission, and can increase the output power of motor, realizes the purpose of energy saving and reduction exhaust emission.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model fuel-water emulsifying firing unit is made up of supply system, Conversion of energy combustion system, output system, and supply system only provides fuel oil.This programme does not change other system of diesel engine, only changes its supply system and forms.Fuel tank 5, oil and water seperator 6, oil transfer pump 7, diesel-oil filter 8, Injection Pump 9 are linked in sequence by low pressure fuel pipe 15, Injection Pump 9 the other ends are connected with oil-water mixer 10 oil-in ends with high-pressure oil pipe 16, water tank 1, water transport pump 3, water filler 2, water jet pump 4 are linked in sequence by low pressure water pipe 13, water jet pump 4 the other ends are connected with oil-water mixer 10 water inlets with high-pressure water pipe 14, and oil-water mixer 10 outlet end are connected with oil sprayer 11; The described oil-water mixer 10 inner oil-water mixers 17 of installing.Described oil-water mixer 17 is the metal wire structure that multiple layer metal web frame or pencil distribute.Be enclosed with circulating water cooling ring 12 on oil sprayer 11 outer walls.
As shown in Figure 1, water transport pump 3 is sent into from water tank 1 water the low pressure water cavity of water jet pump 4 after low pressure water pipe 13 flows into water filler 2 filterings, water jet pump raises hydraulic pressure greater than 10MPa, and the also corresponding rising of water temperature this moment is after high-pressure water pipe 14 sprays into oil-water mixer 10 at a high speed.Similarly, diesel oil sprays into oil-water mixer 10 simultaneously through fuel tank 5 low pressure fuel pipes 15 oil and water seperator 6 oil transfer pumps 7 diesel-oil filters 8 Injection Pumps 9 high-pressure oil pipes 16.Oil-water mixer 10 is preparation aqueous dispersion fuel most important function parts in this programme, usually to form more stable aqueous dispersion, except that the needs mechanical agitation, also need to add suitable surface active agent, and this oil-water mixer 10 utilizes high pressure-temperature water stream at a high speed on the one hand, oil a fluid stream and oil-water mixer 17 and container wall collision form fine droplet, merge mutually, reach churned mechanically effect, oil-water mixer 17 can be the metal wire structure of multiple layer metal web frame or pencil distribution, utilize high temperature and high speed to improve oil on the other hand, the water molecule activity, interpenetrate, constantly reduce interfacial tension, improve the stability of dispersed phase, reach the effect of adding Active agent.Along with deepening continuously of this two aspects effect, the dispersion particle radius constantly reduces, and stability also improves constantly.Analyze from the dispersion interfacial tension, when oil, when water forms microemulsion, interfacial tension will drop to immeasurablel degree, and at this moment, the interfacial tension of profit system may temporarily become negative value less than zero.The dispersion degree of dispersed phase strengthens in this just negative interfacial tension promotion system, and the interface enlarges, even, stable, the transparent micro emulsion oil of final formation.The aqueous dispersion fuel micro emulsion oil for preparing is the vaporific firing chamber that sprays into through oil sprayer 11 with micro emulsion oil, forms inflammable mixture and work by combustion with air mixing.Because temperature is very high under the oil sprayer operating mode, easily make evaporation of water liquid or vaporization in the micro emulsion oil, thus increase air ring 12, in order to safeguard the thermodynamic property of micro emulsion oil.
